Architecture meeting update

• Gabriel: gave update on arch meeting yesterday, see phab:T96903
  • priority is content
  • The usual issue: if we move to SOA, what happens to PHP-only shared hosting? Daniel: isolated APIs and continue a duplicated PHP implementation. Gabriel: or move to next-generation containers.
  • We're already there for VisualEditor (requires Parsoid), but it's optional. As we build new features and front-ends on top of HTML storage...
  • Daniel: abstraction layer for content, need to Associate multiple content with one revision. How to present this.
  • Brion had idea of representing multimedia with a tag extension.
  • Gabriel: Challenge of caches. e.g. Lead images for mobile is going to be stored in RESTBase, graphoid data, ...

Lyon hackathon and ArchCom

Daniel: two sessions + Wikidata session. From phab:tag/hackathon-lyon-2015/ :

1. Governance: phab:T89907 "Discuss and approve a MediaWiki developer community governance model at Lyon hackathon"
2. Priorities: phab:T91744 "Have an architecture guidelines & roadmap session at the Lyon hackathon". But phab:T96903 is a long list.
   • Daniel: this is a hackathon, not an Architectural Summit.
   • Gabriel: * what is concrete?
   • Tim: what is going to happen in the next 6 months or year?
   • Maybe concrete session on how the content clients above will be using RESTBase
   • Tim: Metadata storage, how to attach metadata to revisions, e.g. mobile lead images
   • Daniel: agree on direction if not on the goal.
3. plus Wikidata "bitching session" phab:T92505

(Wikimedia Hackathon 2015 is empty)

Discussion for Hackathon:

• generic mechanism / infrastructure for storing multiple revision-associated kinds of content
• HTML5 content model, widgets, structured data extraction and * presentation

Next week May 20: ArchCom meeting focus on hackathon, no public IRC meeting.
Pick an RfC for discussion at hackathon?, e.g. phab:T73236
Gabriel: Or draft a problem description for discussion.
