The goal is to import artworks in Wikidata from Wikimedia Commons files with the artwork template.
Wikimedia Commons extraction
An extraction of Wikimedia Commons files with the template Artworks has been done by a Wikimedian in september 2014.
The file: http://zone47.com/div/artworks0.zip
Result: 190.000 files with 105 different properties
Table of the 105 properties with occurences: http://framacalc.org/1u7az8lted
Preparation for Wikidata
For a wikidata import:
- remove useless properties (detail, review, informations on the file...)
- merge redundant properties (artist-creator..)
Result: new version with 27 properties.
The file: http://zone47.com/div/artworks.zip
Table of the 27 properties: http://framacalc.org/8pewk3wre2
- Fields values are heterogeneous
- Artworks still in Wikidata and another with artworks with two or more occurences in the table.
At this point, many options. Some proposals:
- Global processing on fields (example on date)
- Division in lots (by institution?)
- First option 1 for some properties then option 2.
- Extract files with well formed metadata first
