Use WikiData About Walters Paintings
The metadata for some of the paintings in the collection of the Walters Art Museum have been imported to Wikidata. Wikidata is the newest project of Wikimedia. Wikidata is a free linked database that can be read and edited by both humans and machines. Wikidata acts as central storage for the structured data of its Wikimedia sister projects including Wikipedia, Wikivoyage, Wikisource, and others. On Wikidata we started the project sum of all paintings with the goal to get an item for every painting in the collection of a museum.
The data is accessible in different ways and already viewable in some prototypes:
If you are going to use Wikipedia data, would it make sense to use Dbpedia instead? Dbpedia at least conforms to linked open data standards. I have never heard of Wikidata, but it doesn't appear to have a SPARQL endpoint, so that's a pretty big red flag.

There is a lot of potential for this. Data in Wikidata means a direct link to Wikipedia, a website used by hundreds of millions of people. Having your information in Wikipedia ensures that it can reach a global audience—an audience beyond Baltimore or even this country. Using Wikidata as your data repository also means you don't have to maintain your own. Not a bad deal, right? :)
