@Marc: For BaseX 8.0, we are planning to speed up our document index, and we could possibly enrich it with some more (possibly user-specific) metadata. I have added a reference to this mailing-list thread in the correspondent GitHub issue [1].
However, I am not sure if we should extend in our existing APIs. Maybe it would be more consistent to provide an additional XQuery Module for that, or extend the Database Module. Additional metadata could be returned via db:list-details(), and we could an updating function, sth. like db:store-details(). What do you think? Any more suggestions are welcome. @Vincent: > I've started to implement along these lines by creating a second database to > hold metadata about documents in the actual database.
