Would be a pretty attractive option for a workshop:
install ruby, write some statements to graphs, write a dataset to file, put up a SPARQL server over the file, use the query DSL, [some other advanced stuff here]
Arto Bendiken
@artob
:+1: Indeed, I could have used that in the RDF.rb workshop I gave here in Berlin two months back.
Thomas Johnson
@no-reply
@bendiken I'm doing one in Hamburg in late Nov.: http://swib.org/swib15/
Arto Bendiken
@artob
Scheduled for another RDF.rb workshop in Nagasaki in two weeks, could certainly use.
Hamburg? Not that far. Could I interest you in a day-trip to Berlin? :)
Thomas Johnson
@no-reply
you probably could. others have already tried to pull me that way for unrelated reasons
I'm coming in via Amsterdam, and probably taking a week and change after the conference to make my way back there
is Nagasaki a business trip? or a conference workshop? or... ?
Arto Bendiken
@artob
Awesome. Will make sure we're around in that time frame, and happy to show you around Berlin. It's a unique city.
Thomas Johnson
@no-reply
thanks. I've heard good things.
Arto Bendiken
@artob
Nagasaki is for this: http://2015.biohackathon.org/ ...they're heavy users of Ruby and RDF.rb. Got invited a few years back, couldn't go--got another invite this year, looking forward to it.
Thomas Johnson
@no-reply
:cool:
I'll be in touch when my flights are all settled for the SWIB thing
Arto Bendiken
@artob
Sounds good.
If that'd be Nov 26, that's Thanksgiving, right? I'm sure we can scare up a turkey or two... ;)
Thomas Johnson
@no-reply
it is, yes. I'm an iconoclast and usual cook duck or goose on turkey day, though.
not really a turkey fan
Arto Bendiken
@artob
Well, you're coming to the city of hohemian iconoclasts, so you're good. :)

@gkellogg
I suppose we have most of the components except a full-featured, Rack-based SPARQL endpoint implementation?
Note that the sparql gem does include rack/sparql and sinatra/sparql, and that there is a spec implementation there.
I also published a Micro Sparql gem a while ago that essentially does this, as I used it for a demo.
I'm giving a talk in about 4 weeks in Minneapolis on RDF.rb, so we can share resources.
Thomas Johnson
@no-reply
@gkellogg yeah, I'll be there in Minn.

Thanks for setting that up, pretty cool!

Hey all! I'm curious to get some feedback on an in-process Apache Jena connector for RDF.rb on JRuby (either 1.7 or 9k series). The documentation is minimal (only a small README), but it is pretty usable already. https://github.com/abargnesi/rdf-jena
Tony Bargnesi
@abargnesi
You can run "rspec spec/repository_spec_jena.rb" to run the RDF::Repository spec tests.
Gregg Kellogg
@gkellogg
@abargnesi that's great! I was just talking with someone the other day about how useful Jena adaptors for parsing/serializing as well as a repository would be. I'll take a look shortly.
Tony Bargnesi
@abargnesi
@gkellogg thanks! feel free to open issues as you see them.
Gregg Kellogg
@gkellogg

@abargnesi a Gemfile would probably be a good idea. I got an error running with jruby-9.0.3.0:

org/jruby/RubyKernel.java:939:in require':LoadError: JRuby ext built for wrong Java version incom.github.rdf_jena.JenaRepositoryService': java.lang.UnsupportedClassVersionError: com/github/rdf_jena/JenaRepositoryService : Unsupported major.minor version 52.0

[rdf-jena] java -version java version "1.7.0_10"
That's the default version of Java on Mac El Capitan
Tony Bargnesi
@abargnesi
Good catch! I will look at how to best declare the java language version. Apache Jena 3+ requires Java 8.
Tony Bargnesi
@abargnesi
@gkellogg Included checks for JRuby and Java 8 at install-time. See abargnesi/rdf-jena#1.
Tony Bargnesi
@abargnesi
Pushed 0.2.1 version to rubygems.
Gregg Kellogg
@gkellogg
@no-reply still need to figure out what’s causing stack-overflows and other things in SPARQL::Client::Repository and RDF::Mongo. Any thoughts?
Thomas Johnson
@no-reply
@gkellogg i don't, but I haven't looked properly yet
will try to do that this afternoon

rdf-raptor is not happy and failing many specs now, Perhaps someone has time to look into it. @dwbutler?
Thomas Johnson
@no-reply
I reorganized and pushed up some old benchmarking work: https://github.com/ruby-rdf/rdf-benchmark
you need to manually download the Berlin generator to get this working for now, but I figure a Rake task is the eventual goal.
just wanted to get it public in case I find time to work on it along with other RDF::Repository stuff

I'm working on a blog post on the HAMT Repository and had the chance to give some thought to thread safety in the process.
I wonder whether you two think it would be worth reworking RDF::Repository slightly to synchronize transactions out of the box? Something like:
  • assign @mutex at initialization
  • wrap the relevant parts of SerializableTransaction#execute in repository.mutex.synchronize { ... }.
