As a relatively new mapper I am rather confused about this discussion about
source. To quote the wiki for the tag, source:
"The source tag is a meta-tag, used for categorising the source of
information added to the database. It is not usually used for
rendering, but it assists with the verification of data, and informs future
editors about the origins of the data they are modifying."
In term of the changeset this is what you find for the change set under
"proposed features/changeset"
"This tag is to be used the same way as source=*
on objects and may be a future replacement to object level source
tagging, when using it, it is highly recommended that your edit should
only contain data from that source."
The former is quite well documented and readily seen by newbies under the
properties window in JOSM. I've no idea how to find the latter within JOSM for
a particular object.
I can be a pain to add source tags to each object but I just hacked the presets
and added a drop down box for these. I though it was good mapping practice as
per the wiki.
I would be tempted to just to tag the changeset but I would have to change the
way I edit and use many more changesets during a typical session. Perhaps I
should and this is why my stats are so bad in this respect!!!
If putting source on the changeset is to be the way forward then it should be
better documented for Newbies and also the changeset tag needs to be readily
viewable for an object in editors. i.e. there when you select it in the
editor. If it already is and I'm missing this, it would be good to know how
you can view this information as I tend to be more likely to change an object
where there is no object source tag.
