Hi Aaron,

Great. Thank you!

Maybe others can fill in the gaps you mentioned, e.g. specs on the SPARQL
endpoint.
I'll ask Laurens (member of our team) if he can check the possibilities for
porting YASGUI to it.

Regards,
Erik

Hi everybody.

I've got some questions for you regarding W3C SPARQL compliancy
 of the latest RYA release.
They are part of the requirements for selecting our companies next triple
store (we've ranked several candidates already, but we'd prefer to go open
source in time).
When answered I suggest to add them to a feature/compliancy list on Apache
Rya Home , good for marketing ;-)  I
could first add them to the Github Rya Documentation

.
Some major features are worked upon (JIRA
)
or maybe in the/a backlog, like Federated queries, RDF4J, SPARQL Web GUI
(Zookeeper).
This must be shown on the overview then as well (imho).

I'm getting more into Rya each day (reading, installing and exploring) and
hope to contribute to it.
Still a lot to learn, so I hope you don't mind me barging in this way.

The compliancy regard the folllowing topics:

SPARQL 1.1 Language
SPARQL 1.1 Protocol for RDF
SPARQL 1.1 Query result format JSON, CSV, TSV, ...
SPARQL 1.1 Federated Query
SPARQL 1.1 Service Description
SPARQL 1.1 Graph Store HTTP Protocol

Some other questions

   - Can Rya handle combined queries (Full text search, spatial)?
   - Is RYA compliant to the the OGC GeoSPARQL standard
   ?
   - Is it possible to set query timeout and max request body size?
   - Can long running queries be killed without killing the session?
   - Is the SPARQL endpoint/CLI accesible with other web interfaces like
   YASGUI?

Erik

Re: [DISCUSS] Graduation?

Hi all,

Shouldn't code for OpenRDF be refactored to RDF4J for graduation?
