We need a new entity type for storing structured data about media files.
From the story time meeting on 2016-02-23:
- It does only have short caption, long caption and full featured statements.
- No uniqueness constraints needed for labels and descriptions.
- Missing references should be less prominent in the UI.
Open questions:
- Which additional datatypes will be needed (e.g. multilingual; second-precision; smart-uri)
- Further investigation of long caption (ALT-texts, etc..) and its format (wikitext, including templates etc..) needed.
- How to represent legends?
