Track usage of entities on client pages in a database table (on the client wiki). Usages that should/could be tracked: * the item linked on wikidata (already tracked on the repo side) * other items referenced explicitly on the wiki page * items used indirectly, e.g. because their label is shown on a page * properties used to access statements of items on a page There should be an abstraction layer that allows code to access the list of entities used by a given page, and conversely, the list of pages using a given entity on a given wiki.

Notes from meeting: - design database schema for service that registers where data is used (keep in mind difference between tracking on a single client vs. global tracking); figure out in which detail usage is tracked (eg referenced explicitely, implicitely or indirectly) -> 13 points - implement the service - hook up property parser and Lua functions to record usage -> 13 points (against a dummy interface; dumb version that includes all referenced entities and not filtering by what is actually being used) - changes should trigger a purge of pages that use the changed data - dispatcher needs to figure out which clients to send a change to (as it is no longer enough to send it to all clients that have a sitelink for a given item) - write API module that gives a list of pages that use a given item
Made individual bugs from the meeting notes (see blockers).
