Hello all,
As you might know, there are plenty of tools
<https://grafana.wikimedia.org/d/000000154/wikidata?orgId=1> analyzing
Wikidata’s content and its usage across the Wikimedia projects.
The new dashboard we would like to present you today, the *Wikidata
Identifier Landscape
<https://wmdeanalytics.wmflabs.org/WD_ExternalIdentifiersDashboard/>*, is
focusing on the external identifiers and their usage on Wikidata. Its
different views allow to answer questions like: how much do our external
identifiers overlap with each other? With how many statements are they
currently described? Which identifiers represent certain topic areas? On
what type of items are they usually used? How can we map the galaxy of our
external identifiers?

On the dashboard, you can browse through different tabs:
- the Similarity Map presents a global overview of the overlap in the
usage of Wikidata identifiers
- the Overlap Network visualizes all Wikidata external identifiers in a
network of nearest neighbors
- the Tables section allows you to check directly the number of items
using a certain external identifier, and the number of items using two
external identifiers of your choice
- the Identifier Classes tab maps the relationships between the external
identifiers belonging to the same class (eg chemistry, cultural heritage,
feminism…)
- the Particular Identifier tab provides for each identifier a map of
its neighbors and some examples of items where this identifier is used
On every tab, the descriptions gives you more information about the
calculation method and the result. You can also check the documentation page
<https://meta.wikimedia.org/wiki/Wikidata_Identifier_Landscape>.

If you have any question, if you find a bug of if you have a request for
future development, feel free to ping me or to comment on this Phabricator
task <https://phabricator.wikimedia.org/T204440>.
And of course, feel free to share the dashboard with people or projects
that could be interested in playing with identifiers :)
