Philippines data from Wikidata

[jnicho02]

Hello Open Plaques,

I am from the Philippines and I am volunteering in a project to map
and include the data about my country's national historical markers into
Wikidata, which is a sister project of Wikipedia. We currently have
included over 500 markers in Wikidata (with photos in Wikimedia Commons)
and you can browse them on the Historical Markers Map, a simple web app I
created to extract the data from Wikidata and put them all on a browseable
map:
https://wmph.github.io/eph-historical-markers-map/

The national historical markers in my country are produced by the National
Historical Commission of the Philippines (NHCP) and its predecessor
agencies since the 1930s. Unfortunately, the NHCP does not maintain an
accurate or up-to-date database of the historical markers that they have
installed. A sister government agency, the National Commission for the
Culture and the Arts (NCCA) is mandated by law to maintain a database of
cultural properties[1] and this includes the NHCP's historical markers. But
as we learned when we talked with their database team, their data is also
not complete nor up-to-date. So we are currently helping the database team
update or correct wrong info in their data while we also use their database
to help complete our own data in Wikidata.

Anyway, you might be interested to incorporate the data that we have
already put into Wikidata into Open Plaques. The data in Wikidata is
licensed under the Creative Commons Zero license so there should be no
compatibility problem with Open Plaques’ Public Domain license.

We do encode the inscription when we have the time and we use Wikidata's inscription property (P1684) for that. Here is an example Wikidata item for a historical marker with the inscription included: https://www.wikidata.org/wiki/Q28869091
