- Would Lexemes be in their own dump or included in the main Wikidata dump?
- When it is planned to enable RDF and dumps (rough estimate is OK)?It will need some work on WDQS side (esp. due to Lexeme/Form thing - right now Updater wouldn't understand that part properly) so I'd like to plan for it.
- Any estimates on how lexical data growth would be looking like? That depends on if we do any mass imports of course. This is important because some performance tweaks for new data will require full DB reload, but if there's not a lot of data we can wait with it for a while.
Topic on Extension talk:WikibaseLexeme/RDF mapping
1. Unless we do something I think they're in the main Wikidata dumps for now. Given that the dumps are a problematic area we should probably think about separate dumps for Lexemes. @Leszek Manicki (WMDE) might be able to say more about which data will be added to which dump at the beginning. (We turned off a lot of exports or stripped them down to the bare minimum for now.)
2. RDF is blocked on finishing this mapping. Once we have agreed on the mapping we can start implementing. I can hold it off on whatever other work needs to be done first in the Query Service. Just let me know. Then we can start creating blocker tickets etc.
3. We'll be asking people to take it slow - especially at the beginning. I hope editors will follow that wish. Beyond that I have a hard time making predictions.
We don't need to block anything on WDQS I think - until we enable Lexeme namespace on WDQS, Updater will ignore it and if it's separate dump then it will live separately and we can enable it whenever we're ready. I just wanted to know when to plan the work on it.
