10 years ago By the way, your query should have a list of triples, not a single triple.
e.g.,
(def results (kr-sparql/query datas (list (list subject predicate '?/o))))but that whole thing can be simplified to something like this:
(def results (kr-sparql/query datas `((~subject rdfs/label ?/o)))Or you could use the RDF API that's designed to query with a single triple.

10 years ago I got your example to work with a few modifications with the current snapshot version:

10 years ago Ok It works fine.
Thanks very much Kevin.
ps : the code is working, but I had a problem for retrieving it from github. The release 1.4.18 seems not to be up to date ... I had to direct download the code before testing it. Perhaps it is normal thing ?

10 years ago Yes old versions will never change. I didn't push a new version yet until we had it tested. That's what I was asking if you could download from here, compile, and run with the 1.4.19-SNAPSHOT.
you would have had to do something like:
git clone https://github.com/drlivingston/kr.git kr
cd kr
mvn clean package installthen on that machine KR 1.4.19-SNAPSHOT will be available.
So I'm assuming that's what you did? If everything is working, I'll push a new version to clojars as 1.4.19.

10 years ago Ok great. Then I'm going to mark this as closed an move toward releasing a new version to Clojars.

10 years ago Hi Kevin, sorry, but did you forget to release a new version on Clojars ?

10 years ago Sorry, I lost track of this. I just pushed KR 1.4.19 to Clojars with the relevant fixes for issues 9 and 10.
Current development version has been pushed to 1.4.20-SNAPSHOT.
This issue is created from #9 .
My question was :
on datas :
When I run :
(kr-sparql/query datas '(purl/AFlat rdfs/label ?/o))it return({?/o #<TypedValue com.hp.hpl.jena.datatypes.BaseDatatype$TypedValue@6084a2ef>})I tried to declare one method :(defmethod kr-clj-ify/clj-ify BaseDatatype$TypedValue [kb l] (.lexicalValue l))without success :-(.After Kevin's request the code I use is :
