Hi GLAM friends, (Trying again as the first ping about this didn’t result in any specific collections or GLAMs.)
Connected Open Heritage[1] keeps moving on, and have so far worked with the WLM database and the upcoming migration to Wikidata, some batch uploads to Commons and preparations for visiting governments and authorities.
One thing we still need some help with is to get in touch with GLAMs who has digitized collections of photos, videos, paintings or drawings, or possibly scanned books (such as travel diaries) of immovable heritage sites[2] that could be relevant to the project. It can be either old connections that you are already in touch with or new GLAMs that you want to work with.
As we have both work time and developer skills in this project we are happy to help with both contacting, coordinating and do the technical part required to get a good cooperation going, as long as you give us some starting points and places to look.[3] If you already have a good relationship with a relevant GLAM we can help only with the parts you ask for, and you can still be the primary contact for the partnership. Suggestions can either be added to https://meta.wikimedia.org/wiki/Connected_Open_Heritage/Partners#Suggestions or sent as an answer here.
