You are effectively duplicating

In Haarlem (the Netherlands), house numbers are either black (ground
level) or red (upstairs addresses). The government denotes this with
22-RD (rood=red) or 22-ZW (zwart=black), which OSM follows.

Just to be clear, you propose removing boundary=administrative from
maritime borders, but leaving the maritime=yes tag? So this will
result in many ways with the only tag maritime=yes?

Hi all,

Thank you all for all feedback. I will take this back to the project.

Just something I'd like to clarify: many of you seem to assume this
introduces a new tagging paradigm. The opposite is true: the proposal
uses a tagging scheme that is already used in about 90 percent of the
countries, and the retagging request only concerns the exceptions. You
might or might not agree with this tagging scheme, but it is the way
things are currently done in most countries.

I would also like to point out that other data consumers do rely on
the presence of admin_level on boundary ways too. For example,
https://www.öpnvkarte.de and https://korona.geog.uni-heidelberg.de/
already rely on admin_level tagging on boundaries (and thus do not
display internal admin boundaries in Poland). There might be more of
them.

Anyway, as I said, I will take this back to the project and will let
you know if there is news.

[Tagging] Tagging request: missing admin_level tags

[Matthijs Melissen]

Hi all,

OpenStreetMap Carto, the default stylesheet on openstreetmap.org, is
considering to change the mechanism for rendering admin boundaries.
The proposed rendering of admin borders will be based on admin
boundary ways rather than polygons. This has a number of advantages -
for example, it will make it possible to style maritime boundaries
differently.

The admin boundary ways are already in the database. However, in some
cases they are missing an admin_level tag. When the proposed style
change will be deployed, boundary=administrative ways without
admin_level tag will no longer be rendered. I would therefore suggest
to make sure admin_level tags are present on all
boundary=administrative ways.

A map showing admin boundary ways without admin_level tag (displayed
in gray) can be found here:
http://product.itoworld.com/map/2?lon=20.00736=51.92203=6
As can be seen, most countries already do have admin_level on ways.
However, in for example Poland, Iran and Australia, this data seems to
be missing.

Moltonel, could you please refrain from making changes that go against

[Tagging] Feature proposal - Rejected - Jewellery shop

[Matthijs Melissen]

Dear all,

The proposal to replace shop=jewelry by shop=jewellery has been rejected.
http://wiki.openstreetmap.org/wiki/Proposed_features/Jewellery_shop

The proposal received 40 votes for, 18 votes against, and 4
abstentions. The approval rate was 68.97%, which is less than the
required 74%.

It is clear that this is a contentious issue within the community.
People on both sides of the debate seem to have strong opinions. The
vote shows that a majority of voters supports changing the tag, but
also that there exists a strong minority that is against the change.
Most people voting against the proposal do so for fundamental reasons,
so I don't think a modified version of the proposal might change the
balance (under current voting rules).

Thanks everybody for the large turnout.

That doesn't really make sense, people use the American spelling
because this is the tag suggested by editors or because it is the tag
supported by data consumers, not because they think it's necessarily
the best tag,

I'm quite sure that most people who voted for 'jewellery' use
'jewelry' when mapping.

For my proposals, I follow the currently documented process with 74%
approval, and therefore consider the jewellery proposal rejected.

However, I think a discussion about a lower threshold, and in general
a formal approval of the voting guidelines by the community, would be
very useful.

I would argue that the German term Regierung does not correspond to
the term government (and that the German language is missing a synomym
for government). For example, Dutch has both the term 'Overheid' which
refers to all branches of government, and 'Regering' which refers to
the national executive branch (and more precisely only to the
(vice)ministers).

Basically you are saying that the English term matches the definition
correctly, but that there exists a near-synonym in Germany that does
not match the definition. I don't think that's enough reason to change
the tag (or its definition).

From the proposal:

Dear all,

Currently, we have the following confectionery related tags:

* shop=confectionery (12045 instances)
* shop=chocolate (730 instances)
* shop=pastry (708 instances)

How should we tag a shop selling cakes? A shops selling croissants and
cinnamon rolls? A shop focussed on chocolate, but also selling other
types of confectionery marketed towards adults?

Should we preserve the shop=chocolate and shop=pastry tags, or should
we make them subtags of shop=confectionery (or shop=bakery)?

I think the second issue is a bigger problem for shop=art, as this tag

A small local Dutch museum sold a painting to a private party, to

That's correct and something I'm aware of. Hubo in Belgium is very
different from Hubo in the Netherland. The chains are not even owned
by the same entity.

Dutch Hubo:

Please keep in mind that this is your personal definition - and
perhaps the definition of the people in your field. But that's not
necessarily the definition of the average English speaker. For
example, Wikipedia calls the following museums all art galleries in
their first line:
* https://en.wikipedia.org/wiki/Barber_Institute_of_Fine_Arts
* https://en.wikipedia.org/wiki/Tate_Modern
* https://en.wikipedia.org/wiki/National_Portrait_Gallery,_London

I don't think either fit your definition. You could say Wikipedia is
wrong here, but I think it does show that English speakers use the
term 'art gallery' in this sense of the word too.

Are you British yourself, by the way?

I don't think this would help, for example Birmigham has the

gallery in your sense of the word.

True, coming up with a precise definition is quite hard though. I
think I would like to include places like job centres, but exclude
museum cashiers or private bus/road work companies. Would something
like this work?

"The tag office=government is used to tag offices of a
(supra)national, regional or local government agency or department. In
these offices, staff directly paid for by the government carry out
administrative jobs to govern the area and/or people."

Could somebody (perhaps a native speaker) improve on this definition?

[Tagging] Galleries versus art shops

[Matthijs Melissen]

Hi all,

This discussion continues the feature proposal 'Discourage tourism=gallery'.

Most list members seem to agree that, in spite of what the wiki says,
tourism=gallery should not be used for places like the MoMA in New
York.

However, it is still not clear to me whether we should distinguish
shop=art and tourism=gallery.

Max proposed the following definitions:

| A gallery is showing art to the public. There is the possibility of
| purchase, but it is only a tiny fraction of the audience which actually
| is buying. The works are by artists the gallery represents. Shows are
| designed by the artist (with help or in collaboration with the
| gallerist). Am exhibition consists typically of new work by the artist
| is usually on display for a couple of weeks only. The business model of
| an art gallery is based on the sales from the art. A gallery usually
| gets a cut of up to 50% of the price of the artwork and is doing the
| dealings with the art collector.

| An art shop is selling art(sy things). Visiting without buying is
| possible, just as you may walk through a supermarket without buying
| anything. The artworks are for sale may be more on the craft side
| of the arts. They usually are of decorative nature and not of
| considerable worth on the art market.
| Artworks may end there as second hand goods. The
| producers of these artworks may not even know their work is in the
| shop. There is no special exhibition, concept or theme other than the
| intent of selling the goods.

I think these are nice definitions that we could work with. However,
it is quite different from the use of the tags now.

First, the wiki page on currently states for tourism=gallery: 'Private
galleries which are primarily funded by selling the works to visitors
would still be tagged shop=art'. This would imply that Max' galleries
should be tagged shop=art.

Second, the tag shop=art has 5316 uses, the tag tourism=gallery only
1526. The data indicates that the majority of art galleries (per Max'
definition) have been tagged as shop=art. Conversely, a significant
part of all shop=art objects, are actually art galleries according to
the definition above.

Furthermore, the line between art shop and art gallery might also be
subjective and hard to draw in some cases.

What do you think, would it make sense to try to keep both shop=art
and tourism=gallery? Or should we discourage either of these options
in favour of the other? Or should we come up with new tags?

[Tagging] Do-it-yourself versus hardware stores

[Matthijs Melissen]

Hi all,

We currently have separate tags for shop=doityourself (37 857
instances) and shop=hardware (24 674 instances).

The OSM wiki gives the following definitions:

Do-it-yourself:
| Do-It-Yourself-stores (DIY for short) are similar to hardware stores, except
| they are generally larger and stock a wider range of products.
| Products sold may include hand tools, power tools, self-assembly furniture,
| decorating products, bathroom and kitchen furniture and fittings, garden
| furniture, electrical goods, fencing, flooring, and more.

Hardware:
| A hardware store, sometimes known as an ironmongers shop in the UK, is
| where you can buy screws and bolts, nails, hooks and other metal materials as
| well as metal tools.
| A hardware shop will often stock a wide range of products which can include
| building, electrical, plumbing supplies, garden tools, power tools,
kitchenware,
| homeware, locks, keys, and a key-cutting. Where these types of product/service
| are supplied in isolation, a different tag may be more appropriate.

As you can see, these definitions are quite similar. Not surprisingly,
taggers have problems with these definitions too. Some examples
* Home Depot in the US is tagged home depot 1161 times as
shop=doityourself, but also 148 times as shop=hardware.
* True Value, according to the wiki a prototypical American hardware
store, is tagged 74 times as shop=doityourself and 106 times as
shop=hardware.
* The Dutch shop Hubo, which might fit the Hardware definition better,
is tagged 23 times as shop=doityourself and only 4 times as
shop=hardware.

Would it make sense to keep distinguishing between shop=doityourself
and shop=hardware? If so, how could we make the difference more
precise?

There is new tagging in the proposal. It is, respectively:
- office=government, government=register_office
- office=government (with correct admin level)
- office=government, government=register_office
- office=government, government=tax

Thanks. I think the proposal takes some of these values into account
already. I don't think the others necessarily need to be included in
the currrent proposal.

Thanks for your useful comments.

I'm not sure if I fully understand your explanation. How would you
categorize the following examples:

* http://www.mudam.lu/en/le-musee/la-collection/currently-at-mudam/
* http://www.whitewallgalleries.com/

Note that the wiki currently states: 'Note that art galleries very
often have the word "museum" in the name. Despite this, if they are
primarily displaying art, they should probably take the tag
tourism=gallery'.

It is not clear whether you (and the people agreeing with you) do or
do not agree that this statement in the wiki is correct.

Isn't the division of powers theory referred to as 'three branches of
government'? That seems to indicate that government can encompass the
legislative power as well.

Also, note that on local level, the branches are much more mingled,
and usually share a single building (the city council usually meets in
the building where the mayor/aldermen work).

Good point. Do you, or anybody else, have a better definition? I think
I'd prefer the job center to be included, but the museum to be
excluded.

True, but I don't think that's really a problem. If the reality is
different in across countries, we can expect the tagging to differ as
well. I think the wiki page should provide some international
guidelines, but in the end each national community can decide how to
implement them (similarly to how each country decides what counts as a
trunk road).

Good point as well. However, note that this differs a lot between
countries as well. For example, in some countries, if you have a tax
question, you can just walk in to the tax office, where'll you be
redirected to the tax inspector that will actually handle your tax
forms. In other countries, you can only reach the tax office by phone
or mail. There are also many forms in between places where you can
just walk in, and places that are closely guarded. For example,
ministry buildings are generally relatively closed off, but sometimes
you might need to go there to get certain documents. For instance, in
Luxembourg you can register your diplomas in person at the higher
education ministry. An other example, you would not usually go to the
city's traffic department are usually, but you might need to go there
if you need signs to close of a parking space.

Re: [Tagging] Discussion about Multivalued Keys

[Matthijs Melissen]

Hi Colin,

Thanks for getting this discussion started. I agree it's fine to use
the proposal template also for proposals that are not about proposing
a concrete tag.

One thing to take into account in this discussion is that multi-valued
keys often move the problem to the data consumer. For that reason I'd
recommend to avoid them in many cases.

Take for example your example shop=supermarket, shop=bakery.
Independent of the exact way of tagging, using a multivalued tagging
scheme forces the renderer to make a decision between a supermarket
and a bakery icon. Basically, there is no possible way for the
renderer to support a multi-valued key here! The renderer might have a
rule that considers supermarkers always more important than bakeries,
or vice versa. But I think it's much more useful if the mapper decides
what's the main function, supermarket or bakery, rather than forcing
the renderer to make a choice.

[Tagging] Feature Proposal - Rejected - Aquatics centre

[Matthijs Melissen]

Dear all,

The proposal for aquatics centre has been rejected:
http://wiki.openstreetmap.org/wiki/Proposed_features/Aquatics_centre

The proposal received 17 approving votes, and 28 opposing votes (38%
support). I would like to thank everybody for voting.

From the comments, it follows that there is strong support for the tag
combination leisure=sports_centre + sport=swimming to map such
features. I have therefore taken the liberty to document this tagging
combination explicitly on the wiki:
http://wiki.openstreetmap.org/wiki/Tag:leisure%3Dsports_centre#Combinations

I also opened a couple of requests at various OSM projects:
* I asked iD to render leisure=swimming_pool with a blue rather than a
white outline, call leisure=swimming_pool something like 'Swimming
pool (water area only)', and add a searchable preset 'Swimming pool
(facility)' or 'Swimming pool (sports centre)' or something of the
sort for the tag combination leisure=sports_centre, sport=swimming
(https://github.com/openstreetmap/iD/issues/2927)
* I asked JOSM to call leisure=swimming_pool something like 'Swimming
pool (water area only)', and add a preset 'Swimming pool (facility)'
or 'Swimming pool (sports centre)' or something of the sort for the
tag combination leisure=sports_centre, sport=swimming (see
https://josm.openstreetmap.de/ticket/12432#comment)
* The project opentreetmap-carto was asked to add support for the tag
combination leisure=sports_centre, sport=swimming
(https://github.com/gravitystorm/openstreetmap-carto/issues/2018)

Of course it is up to decide to these projects what to do with these requests.

In any case, I would like to ask mappers to make sure that
leisure=swimming_pool (Overpass Turbo: http://overpass-turbo.eu/s/dYB)
is only used to mark water areas. The entire facility should marked as
either leisure=water_park or leisure=sports_centre + sport=swimming.

[Tagging] Art galleries/museums

[Matthijs Melissen]

Hi all,

The wiki defines the tag tourism=gallery as 'an area or typically a
building that displays a variety of visual art exhibitions' [1]. This
is an officially approved tag [2]. In addition, the wiki page on
tourism=museum [3] specifies that art galleries should be tagged as
tourism=gallery, even if they have 'museum' in the name.

However, practice shows that the tag tourism=gallery is not very
frequently used. We have currently 54 951 instances of tourism=museum,
versus only 1 505 instances of tourism=gallery. I had a look at some
famous galleries: the MoMA in New York, the Uffizi in Florence, the
National Gallery of Art in Washington DC, the Van Gogh Museum in
Amsterdam, the Musée d'Orsay in Paris, and the Guggenheim Museum in
Bilbao. It turned out that all of them are tagged as tourism=museum.

This might be partly caused by ignorant mappers, but perhaps there is
also a more fundamental problem. The line between a gallery and a
museum is not always easy to draw, especially in continental Europe,
where many museums have both historic and artistic exhibitions
(compare for instance the Louvre). Also the fact that many galleries
are called 'museum' does not help.

How should we continue from here? Should we try to improve the tagging
situation? Or should we discourage tourism=gallery, making it a
subtype of tourism=museum?

The tag shop=jewelry is one of the few tags that use American rather

[Tagging] Retag request: swimming pools

[Matthijs Melissen]

Dear all,

Recently, amenity=swimming_pool has been officially marked as
discouraged. In addition, a vote was carried out to propose a tag for
swimming pools that are used for sport or swimming lessons. This vote
was rejected, but from the comments of the voters,
leisure=sports_centre + sport=swimming has emerged as a suitable tag
combination for such objects.

I therefore have two retagging requests. It would be great if mappers
could have a look at this in their local area.

* Please change the tag amenity=swimming_pool into
leisure=swimming_pool (Overpass Turbo:
http://overpass-turbo.eu/s/dYz).
* Please make sure that leisure=swimming_pool is only used to mark
water areas. Tag the entire facility as either leisure=water_park or
leisure=sports_centre + sport=swimming (Overpass Turbo:
http://overpass-turbo.eu/s/dYB).

To use the Overpass Turbo links, browse to the right area and click 'Run'.

[Tagging] Jewelry/jewellery shops

[Matthijs Melissen]

Hi all,

We currently use British English for almost all OSM tags. Jewellery
shops however are typically tagged with the American English variant
shop=jewelry (20083 occurrences), and hardly ever with the British
English variant shop=jewellery (187 occurrences). Editors and data
consumers only support the American variant.

Some mappers have proposed switching to the British English version.
I'm not sure if that's really is a good idea. It wouldn't be an easy
task, as it would require synchronisation between mappers, editors and
data consumers. The gain would be fairly minor and the disadvantages
rather large: all data consumers that handle jewellery shops would be
required to update their code. On the other hand, maybe it makes sense
to try anyway.

If we decide to accept the tag shop=jewellery and mark shop=jewelry as
discouraged, we should have at least a good plan. Without plan,
nothing will happen, as mappers don't want to use unsupported tags,
and data consumers don't want to support unused tags. Of course we
can't decide what editors/data consumers should do. However, we could
come up with a recommendation, and hope editors/data consumers are
willing to follow it. An example plan/procedure could look as follows:

Editors:
- The first 6 months after acceptance of the proposal to switch,
editors should keep producing the old tag shop=jewelry only. This
gives data consumers time to make arrangements to support the new tag.
- The following 3 months, editors might either produce shop=jewelry or
shop=jewellery.
- After 9 months from acceptance of the proposal, editors should only
produce shop=jewellery.

Data consumers:
- Within 6 months after the acceptance of the proposal, data consumers
should accept shop=jewellery in addition to shop=jewelry.
- When usage of shop=jewelry has declined sufficiently, data consumers
can stop supporting shop=jewelry. This is not expected within 12
months after acceptance of the proposal, and likely much later.

Data:
- The first 6 months after acceptance of the proposal, the data should
remain unchanged.
- After 6 months, the amount of shop=jewelry tags is expected to
decline in favour of shop=jewellery tags. It is hard to predict how
long this process will take.

Wiki:
- 6 months after the acceptance of the proposal, shop=jewellery should
be marked as recommended tag.
- 9 months after the acceptance of the proposal, shop=jewelry should
be marked as discouraged.

As you can see, this is not a simple proposal. There are also some
risks involved, for example because it is unclear whether data
consumers and editors would be willing to follow the recommendations.

All in all, it is a fairly large operation for a relatively small
improvement, and I'm not sure if it's worth it. I wonder though what
other mappers think. Would it make sense to switch the recommended tag
to shop=jewellery? And if we do so, would a plan similarly to the one
above make sense?

maintainer of the openstreetmap-carto stylesheet.)

[Tagging] Public buildings

[Matthijs Melissen]

Hi all,

The tag amenity=public_building has been marked as 'Don't use' on the
wiki since 2010 (see
http://wiki.openstreetmap.org/wiki/Tag:amenity%3Dpublic_building ). As
far as I know, marking the tag as 'Don't use' has not been discussed
extensively, and the tag is still very commonly used (111 941 times
currently). I therefore think it would be worth to discuss this tag
once more.

Initially I didn't have much problems with this tag, and I have used
it commonly to mark government buildings. However, when I started
looking at how this tag is used (with Overpass), I discovered that it
is indeed use for quite a variety of things. It saw it being used for
government buildings, train stations, expo halls, art centres,
municipal sport centres, and band stands, amongst others. Nearly all
of these have more specific other tags.

In particular, potential replacement tags for government tags are
office=administrative (26 836 times in use) for central government and
office=administrative (8 725) for local government.

I think we have a choice of two options:
1. Accept the tag - in that case we'd need to come up with a clear
definition, and decide how it compares to the office=administrative
and office=administrative tags.
2. Reject the tag and mark it as discouraged on the wiki..

The tag is currently supported by JOSM, but not by iD. If we decide to
approve this tag, it would make sense to ask iD to support it. On the
other hand, if we decide to discourage it, it would make sense to ask
JOSM to remove the preset, and preferably, even add a deprecation
warning to the validator.

What do you think? Which way would you prefer to go?

It was in fact 7 days, but your point is still standing. Some users
have requested an extension of the voting period. I doubt an extension
will change the outcome of either of the proposals (Aquatics centre
and Discourage amenity=swimming pool), but if people prefer more time
I don't mind either. I therefore have extended the voting period for
both proposals by an additional week.

To me it is not clear that this is a solution, as the definition of
building=public is equally vague. Is a prison a public building? A
band stand? A theatre? A bus depot?

Re: [Tagging] Feature Proposal - RFC - Aquatics centre

[Matthijs Melissen]

Thank you for all feedback. The feedback brought forward a couple of
valuable points, but in my opinion these points don't require a change
to the proposal. In particular, I don't think it's useful to
explicitly state in the proposal whether or not customer parking
should be included, and will leave this decision to the individual
mapper. I also think aquatics centres are distinct enough from regular
sport centres to warrant their own tag. The discussion on civic
landuse is independent of this proposal. Thanks again for all input!

[Tagging] Tagging tourist offices

[Matthijs Melissen]

Hi all,

Tourist offices are currently tagged as tourism=information, information=office.

The tag tourism=information is also used for guideposts, maps, boards,
etc. In my opinion, the tagging for tourist offices is quite complex,
and the grouping of tourist offices with things like guideposts is not
very intuitive. On the other hand, data consumers will probably not be
eager to start supporting a different tagging scheme, and it will
probably take quite some time to change the data to the new tagging
scheme.

So my question is, would it make sense to propose a different tagging
for tourist offices, for example tourism=tourist_office or
office=tourism? Or should we stay with the current tagging? I'm myself
quite ambivalent on this issue, and I'd like to hear your opinion.

I can change it in the main text, but I'd prefer to leave it like that

I had a look at the data, but for comparable facilities such as water
parks, sport centres and theme parks, the parking area is usually not
included in the areea. I don't think it makes sense to suddenly
deviate from the current practice, so I will not explicitly require
parking areas to be included in the area in my proposal.

For indoor aquatics centres, I can imagine the leisure=aquatics_centre
would normally be placed on the building.

Hi all,

I have created a proposal page for the tag leisure=aquatics_centre:

The proposal is deliberately rather basic and does not contain a lot

That doesn't seem to be exactly true, I can find aquatic(s) centre in

I like this one, and I think going with two main tags, water_park and
aquatic_centre (I think we should use UK spelling), is a viable
option.

Alternatively, would aquatic_centre also work as an encompassing tag,
using subtags to specify the usage, as Holger suggests? Would it be
strange to refer to a subtropical waterpark or an outdoor swimming
pool with toys and water slides as an aquatic centre?

I suppose this is the best we have. If nobody comes up with a better
tag for the area around a swimming pool (indoors or outdoors), I'll
start a proposal to standardize on leisure=water_park. It would
perhaps slightly deviate from normal English usage but I don't see a
better way to disambiguate between swimming pool as water area and
swimming pool as the facility including amenities.

Does this including indoor swimming pools (for example public swimming

And for the native English speakers: it's still not clear to me

Re: [Tagging] Swimming pools

I collected some usage statistics of pools I know:

Indoor swimming pool, building:
5x leisure=swimming_pool
2x amenity=swimming_pool
1x leisure=water_park
1x leisure=sports_centre
1x leisure=sports_centre+sport=swimming

Indoor swimming pool, water area:
10x not tagged

Outdoor swimming pool, area:
5x leisure=water_park
2x amenity=swimming_pool
2x not tagged
1x leisure=park and sport=swimming

Outdoor swimming pool, water area:
5x leisure=swimming_pool
2x leisure=swimming_pool and amenity=swimming_pool
1x natural=water
2x not tagged
1x water area under construction

The statistics make the overloading of leisure=swimming_pool for two
different purposes very clear.

The difference between these two is not always clear in my opinion.

On the other hand, I can find on the internet 'Splashdown waterparks',
'Calyspo Cove waterpark', and 'Sandcastle Waterpark' as

Would aqua park be any better? I suppose still it still wouldn't work
for pools mainly used for sport swimming or swimming lessons?

Sorry, I think I misunderstood you. I wondered if you (or somebody

[Tagging] Swimming pools

[Matthijs Melissen]

Hi all,

There are currently two tags for swimming pools in use:
* leisure=swimming_pool (511 413 occurences)
* amenity=swimming_pool (46 495 occurences)

Historically, amenity used to be the more popular tag, but usage has
shifted to leisure, with amenity now making up less than 8% of the
instances. Would it be time to mark the amenity-version as
'discouraged' on the Wiki?

In addition, it seems that the swimming pool tags are used for two
different things: the pool itself, and the entire building/area
(including showers, cafe, etc.).

Would it be useful and possible to resolve this ambiguity? We
currently have leisure=water_park, but it seems to more focussed on
recreational swimming with water slides etc. Does it make sense to use
leisure=water_park for indoor swimming pools that are focussed on
swimming lessons or speed swimming as well? If not, should we use
another tag for such facilities? Any other suggestions to resolve the
ambiguity?

There has been a long tradition of this mailing list (and, before it
branched off, the talk mailing list) making recommendations on tagging
schemes, so I see no reason to suddenly question this. In this case
the recommended tag is the more popular tag, but there have also been
instances were a fewer used tag was recommended.

Unfortunately, contacting mappers individually has a very low response rate.

For my bookmaker changes, I contacted 20 mappers individually through

three of them. This was to ask me help with retagging, but I'd guess
asking them for their opinion would give a similar low response rate.
With less frequent mappers, I'd expect the response rate to be even

[Tagging] Tagging of historic=monument

[Matthijs Melissen]

Dear all,

Openstreetmap-carto (the default rendering style on openstreetmap.org)
will soon render objects tagged historic=monument with an icon.

There is currently a large number of objects incorrectly tagged as
historic=monument.

The definition of historic=monument according to the wiki:
'A memorial object, especially large (one can go inside, walk on or
through it) and made of stone, built to remember, show respect to a
person or group of people or to commemorate an event'.

Note that this tag should not be used for national heritage buildings
(called listed buildings in some countries). The word 'monument' does
not have this meaning in English. Instead, historic=yes, the heritage
key, or the listed_status key could be used for such buildings:
http://wiki.openstreetmap.org/wiki/Key:listed_status
http://wiki.openstreetmap.org/wiki/Proposed_features/heritage

It would be good to correct as many incorrectly tagged objects as
possible before the tag is rendered. This map can be helpful for that:
http://www.historic.place/themes/monuments/map.html

See https://github.com/gravitystorm/openstreetmap-carto/issues/1532
for the discussion on Github.

No.

 As tagged it says you cannot walk there.

This is correct. There is a security checkpoint at the gate, and
pedestrians are not normally let in unless they are known to security.
This is different from a national border checkpoint, because there are
no such checkpoints at places where the public can cross the border,

Re: [Tagging] AE and BE orthography in tagging

 Recently I had amened the shop=jewelry page with a short notice that
 shop=jewellery should be preferred, as this is British orthography and the
 generic tagging rules/guidelines state that tags should be in British
 English where possible.

Note that shop=jewelry is not the only US English term we use.

Others include (I'm not a native speaker so correct me if I'm wrong):
- railway=subway rather than railway=metro or railway=underground (in
UK English, a subway is a pedestrian underpass AFAIK).
- highway=elevator rather than highway=lift
- sport=soccer rather than sport=football.

I'm sure there will be others.

In the case of shop=jewelry, most data consumers only support the US
spelling. Usage stats for the UK spelling are currently about 1,1%.
Getting all data consumers to change to the US spelling would be a
huge hassle.

If we want to change spelling, I would prefer a choreographed process,
for example an announced automatic edit one year in the future, in
order to allow data consumers to prepare themselves.

Re: [Tagging] Proposal: Rename wiki status Approved to Published

I appreciate your effort to bring more clarity in the different wiki statuses.

However, I don't think changing the status 'Approved' to 'Published'
is a good idea. In my opinion, 'approved' is exactly what it is: a
proposal approved by the OSM community.

The fact that only a small number of people vote is not relevant, as
anybody in the community can get involved in the tag selection process
if they want to.

In short, I oppose this proposal.

 Using the default OSM-Carto layer for a project isn't very professional. The

That's not necessarily true. According to CARTOGRAPHY.md, the purposes
of the default layer are:

- It's the primary feedback mechanism for mappers to validate their
edits - so detail is useful
- It's a major part of the impression visitors to osm.org receive - so
clear design is useful
- It's an examplar stylesheet for rendering OSM data - so easy
customisation is useful

That said, as the openstreetmap-carto is a one-size-fits all map,
there are often better maps for specific situations.

Yes, it was pointed out to you already:

Yes, I also think this is one of the more common shops that has no

 Checking Tag-info it's 8/6 in favour of electronic_cigarettes over 
 e-cigarettes.

Currently, the most common tag is shop=e-cigarette:

e-cigarette x170
e_cigarette x10
electronic_cigarettes x8
electronic_cigarette x4
e-cigarettes x6

 To me, electronic_cigarettes is clearer  should be used, but I thought it

Do you suggest to list all other shop types, including well-known ones

 The wiki page is very recent with only two contributors. I wouldn't be
 surprised if e-cigarette in the db was also contributed by no more
 than 1-2 mappers. I suggest contacting them to make sure that they are
 ok with e_cigarette, and then make the change to wiki and db.

There are at least 30 mappers who have used shop=e-cigarette. Almost
all of them started using this tag *after* user StephaneP imported
about 80 e-cigarette shops in France.

I also think that e-cigarette would be better than e_cigarette, as the
- does not represent a space, and e-cigarette is a regular English
word, used for instance in newspapers.

 If there is a better word, or a tag that is already used, we can discuss it

I would use a subtag, like natural=water, water=pond, pond=fish_pond.

The paradoxic effect of adding more detailed tags is that the data
gets less useful to data consumers, because most data users won't add
particular processing rules for fish ponds, while if we use a subtag,
they could still use the rules for water=pond.

[Tagging] Change of rendering: place of worship and terminal without building tag

[Matthijs Melissen]

Dear all,

In the next version of the openstreetmap-carto style sheet (the
default rendering used on openstreetmap.org) there will be some
changes that might highlight current tagging errors.

In particular, areas tagged with amenity=place_of_worship or
aeroway=terminal that do not have a building tag will be no longer
rendered as a building.

It is therefore suggested to explicitly add a building=yes tag (or a
more specific building tag) to all buildings tagged with
amenity=place_of_worship or aeroway=terminal. Objects tagged as such
that are not buildings of course do not need to receive a building
tag.

Re: [Tagging] Change of rendering: place of worship and terminal without building tag

[Matthijs Melissen]

I had a look in Padova, and I noticed that most polygons tagged
amenity=place_of_worship in that area are not actually buildings. They
include the gardens, parking areas, and in some cases even tennis and
soccer pitches that apparently are part of the church. In such cases,
a building=yes tag is of course not necessary, and I think it would
also be an improvement if such areas are not rendered as buildings.

I went through about 120 objects in Padova in 10 minutes or so, so
checking them can be done quite quickly. I think the quickest way to
handle this is by installing the Todo plugin in JOSM, opening the Bing
layer, and using the Export-JOSM option. Then you can add all churches
to the Todo list. Go to the next one with the ] key.

I'm not in charge of the release cycle, so I can't tell exactly when
this will be rolled out, but I think the plan is to roll this out
between now and a couple of days.

I should also mention that the change will only influence the gray
building-like rendering. The religion icon will stay in place
independent of the absence or presence of a building tag.

Exactly, hence my last line:
 Objects tagged as such that are not buildings of course do not need to

If a place of worship is not a building (including places of worship
that are only tagged as node) it does not need a building tag, but if
a place of worship is a building, the building tag is required (to
distinguish it from places of worship that are not buildings).
