If we need to use the WDQS (or something analagous to it) for some of our searches (see T194185 T194245 T194255), then we need to store commons data in BlazeGraph
Wikidata already does this, so perhaps we could copy their approach?
Other considerations:
- Do we need another instance of BlazeGraph for commons? A Commons Data Query Service? Or would it be appropriate to use the WDQS?
- We need to decide how to store data about files (as opposed to wikidata items)
- We'd probably need a mechanism to back-populate BlazeGraph with existing commons data
