Minutes

1. Most recent PRs
   • "remove requests" PR
     • merged in but needs follow-up patches
     • too many un-related things jumbled in by Nick
   • several recent PRs are ok, one merged, one needing more consideration
2. PR Backlog
   • an attempt was made to review and close PRs where no response from proponent to review questions has been given for 2+ months
     • only 1 PR closed 1 several others only 1 month waiting so far, will review later
3. Stores
   • Nick and Edmond are currently using the SPARQLStores
   • Nick is motivated to improve SPARQLStore so will add in more PRs over next 3 months
   • FileWatcherStore:
     • proposed by Nick to (re)load an in-memory graph based on changes to RDF files in a dir
     • pseudo code:

g = Graph("FileWatcherStore")
g.open("path-to-dir", reload_individual_files=True)
if reload_individual_files:
    secretly create a Dataset with a Graph() per file
    reload per file
else:
   create just a graph, put all files' content in there
   reload whole lot on any change

One Q: what to do about graph-aware files, trig, JSON-LD? A: v2.0?

• HDT store reviewed and purpose discussed
  • Nick will look into HDT Store installation for example for FileWatcherStore

4. rdflib-jsonld

   • No progress to date.
   • Nick to investigate implementing 6x JSON-LD test suites (only 1 implemented now) so we can know the status of rdflib-jsonld wrt all JSON-LD tests

5. Timetable for 6.0.0

   • must haves
     • tidy-up
       • g.serialize() --> turtle, decode (UTF-8)
         • str(g) ?
         • g.stringify(format="turtle", encoding="utf-8")
         • g.to_string(format="turtle", encoding="utf-8")
         • g.string (property) --> calls g.serialize(format="turtle").decode("utf-8")
         • g.print(format="turtle", encoding="utf-8") --> calls g.serialize(format="turtle", encoding="utf-8"))
       • g.add(()). /g.remove(()) --> g.add() -- Ashley to benchmark
         • perhaps too big a change for 6.0.0
     • documentation
       • reference examples/ code in rdflib documentation - Nick
       • Edmond has indicated to Nick how to include code files in RST files
     • document release process
       • Nick to push his notes from 5.0.0 release process into developers.rst in docco
