I agree; that's apparently not what the community has decided.

It could, but again I don't think that is how the community has chosen
to model them.

Otherwise, what is P1629 for? Note the original description:

https://www.wikidata.org/wiki/Wikidata:Property_proposal/Archive/27#P1629

"item corresponding exactly to the concept represented by the
property, if applicable."

> I think your particular question is that around bullet point 3

What question? I wasn't aware that I asked one.

Re: [Wikidata] Wikidata in the LOD cloud

Andy,

It looks like P3348 is not actually filled out completely and a bit
incorrectly to my eyes.

1. Wouldn't "National Library of Greece" be instead represented by "issued
by" P2378, instead of P1629?  Look at the properties for the type
https://www.wikidata.org/wiki/Q18614948
2. Secondly, what is so important to know about the National Library of
Greece Authority Records ID?  that could all be captured on the property
P3348 itself.

   - It's an external identifier.  We already know that through the
   authority assumption and ExternalId type.
   - there are a few things to say about the identifier, such as what does
   it really represent?  a work? a title? both?  broadly any single item in
   their *holdings*?  ( look at how https://www.wikidata.org/wiki/Q18609040
   uses facet of P1269 to hold the representation "taxon" at a higher level
   for all property that represent a "taxon" like
   https://www.wikidata.org/wiki/Property:P627 )
   - Are the same IDs also held and included in a particular named database
   that often gets cited or referenced?  Then we should say that they are
   included in that named database with some property (of which I don't know
   if we have something that works for that currently)
   - Are the IDs constrained and only issued and generated for some holding
   type or set of collections for National Library of Greece, for example,
   only official active holdings (not dropbox holdings that have not been
   vetted)
   - Is there an email or phone number for the Authority Records questions,
   then I'd add that also to P3348.
   - What else is there to say about the IDs, what they represent, who
   issues them, etc.  Capture all the metadata of the authoritative ids on the
   ID property itself.

I think your particular question is that around bullet point 3, where an
authority might maintain 2 or 3 holding types or collection sets, and then
issue sets of identifiers for those 2 or 3.  Each holding type or
collection set might be in a database that is named and known and often
cited and has many things to say about the database itself, like who owns
it, when it was first created, etc.  Irrespective of all the sets of ID's
that it might contain.

I think we should have a separate entry for each entry in the LOD
Cloud database; if necessary, sets of two or more of the can be
grouped under a parent item.

Re: [Wikidata] Wikidata in the LOD cloud

[Egon Willighagen]

How will we handle LOD entries for data sets provided by a third party?

For example, Bio2RDF released over time quite a few data sets, each having
a separate entry in the LOD cloud, e.g. Bio2rdf::DrugBank?

Do we create a separate Wikidata item for that? Link it to the Wikidata
item for Drugbank, so that one database can have more than one LOD Cloud ID?

What do you think?

This has highlighted an issue I've been concerned about for some time;
the lack of granularity in property P1629, "subject item of this
property".

For example, the data set has an entry for "National Library of Greece
Authority Records", which corresponds to our property P3348 "National
Library of Greece ID". Yet the P1629 on that property is for Q1467610,
"National Library of Greece" -  we have no item for the ID or its data
set.

Of course, one institution can have many such ID types, and thus
Wikidata properties.

There was quite strong opposition when I tried to create more items
for sets of IDs (one successful example, for instance, is Q51044 of
ORCID iDs). I think we will need to revisit that.

In this case, they aheva  JSON file, so I sent a link to that to
Magnus, and he added it.

More generally, if I have the IDs and short descriptive text in a
spreadsheet, I use:

Hi all,

a question here:

P8605 is shown as string, e.g. as "doi" in 
https://www.wikidata.org/wiki/Q5188229  , which is the last path segment 
of the identifier,  shouldn't this be "http://lod-cloud.net/dataset/doi; ?


At least for the LOD Cloud project.

When approved, a fifth example was added, for a Bio2RDF subset in the LOD
cloud, linked the Bio2RDF entry in Wikidata itself (and not a Wikidata item
for the subset). That would be possible, but then bio2rdf-pubchem (and
many, many more) will be linked to that Wikidata item for Bio2RDF. Is that
what we want? Or should bio2rdf-pubchem be linked to the PubChem entry in
Wikidata? Etc?

What do you think?

Hi SJ,

I think we already have that with
https://www.wikidata.org/wiki/Property_talk:P973 in some fashion?

> This is to be used to provide links to reliable external resources that

Scroll down on that link and look at its listed patterns that eventually
get added to the TODO list.
(look at the other *See also* properties it lists as well - which I often
use)

NOTE: I'm not an expert on this particular P973 property of Wikidata
however.

Oh and one thing I forgot: It would be pretty helpful for further
automating this if we had the mapping between Wikidata's property and
the LODCloud entries. Anyone up for proposing a new property for that?

Re: [Wikidata] Wikidata in the LOD cloud

[Egon Willighagen]

Of particular interest is the link counts, based on formatter URI for RDF
resource (P1921).

There are 167 property - P1921 combinations: https://w.wiki/YsV

Calculating the number of links times out when run for all properties:
https://w.wiki/Ysk So, an iterative script is likely more practical.

But basically, the query just counts the number of items with a property,
but limited by the properties that have a P1921 defined. Surely, that can
be done more efficiently.

[Wikidata] Wikidata in the LOD cloud

[Daniel Mietchen]

Hi all,

the newest version of the LOD cloud is just a week old,[1] but the
underlying information for Wikidata is out of date by several years.[2]

Has anyone looked into streamlining the data submission process?

Best,

Daniel

Re: [Wikidata] Wikidata in the LOD Cloud

[Lucas Werkmeister]

Hi Ettore,

speaking as the person who’s entered the current data into the LOD
Cloud… no, I’m afraid it’s not as easy. Some of our namespaces (i. e.
RDF formatter URLs) are wrong, some of the namespaces in the LOD Cloud
are wrong, some datasets just don’t have a clean namespace (or they have
several of them), some of our properties map to more than one LOD Cloud
dataset, some LOD Cloud datasets map to more than one of our properties,
and in general this is all just a terrible mess.

We might be able to start cleaning up this mess if we create a property
“LOD Cloud identifier” or something like that, but I think if you try to
match datasets between the two databases automatically you’re just
asking for trouble.

Cheers,
Lucas

Re: [Wikidata] Wikidata in the LOD Cloud

[Ettore RIZZA]

Dear all,

stop me if my question is naive or stupid. But I see that a dataset like
Europeana is both in the Lod Cloud and as a property in Wikidata
<https://www.wikidata.org/wiki/Property:P727>. However, the method using
the "Formatter URL for RDF resource" property does not work because this
property is missing from Europeana ID. How many other cases like this?

But I see in this simplified version of the Lod Cloud
<https://jqplay.org/s/bgiJvPKryC> that each dataset has a namespace. Would
not it be more efficient to match Wikidata and Lod Cloud using this
namespaces in a series of Sparql queries <http://tinyurl.com/y8taazzm>?

Cheers,

Ettore

Previously it was manual work, yes, and for properties not in the LOD

I’ll try to resubmit Wikidata now and see how the submission process has

Looks like after the last update Wikidata dropped out again? 
https://lod-cloud.net/versions/2018-30-05/lod-data.json contains 
Wikidata, but in https://lod-cloud.net/lod-data.json it seems to be

[Wikidata] Wikidata in the LOD Cloud

[Léa Lacroix]

Hello all,

Thanks to Lucas who filled the necessary requirements, Wikidata now appears
in the LOD cloud graph: http://lod-cloud.net

Currently, the graph doesn't display all the actual connections of
Wikidata. The only connections that show up are the properties that link to
other projects or databases, and having a specific statement on them to
link to an RDF endpoint.

If you see something missing, you can contribute by adding the statement
“formatter URI for RDF resource” on properties where the resource supports
RDF (example <https://www.wikidata.org/wiki/Property:P214#P1921>).

You can learn more about the procedure to update the graph and a list of
the existing and missing datasets here
<https://www.wikidata.org/wiki/User:Lucas_Werkmeister_(WMDE)/LOD_Cloud>,

Thanks to Lucas and John for making this happening!
