Writable file formats by software application

I was wondering what the state of data about writable file formats per software application is in Wikidata. Here is a visualization of the data as of today:

What I learned from this visualization is that we need to enter more data about what writable file formats are supported by various software applications. Please let me know if you are aware of sources that list information about writable file formats that could be scraped to supply additional statements for Wikidata!

Feel free to try this query yourself here. I look forward to re-running this query periodically to see how the process of making this data more complete unfolds.

Wikidata: Archival papers held by institutions

I was curious to know how many links to archival collections are being added to items about people in Wikidata. I wrote a SPARQL query for the Wikidata Query Service to find out.

This query makes use of Property 485 “archives at” and the bubble chart visualization is one of the built-in options for data display of the Wikidata Query Service.

The institutions named the most often by the “archives at” property are in the largest bubbles. Yale University Library and the Beinecke are in the middle layer as of today. I would like to add enough links to archival collections at these two institutions to see this visualization change (with the bubbles for Yale and the Beinecke increasing in size) before the end of 2016.
