Isnt there any offcial w3c spec for trix like for trig? Dr. ir. H.M.

Right, I forgot TriG is not the only Quads format so I have generalized the importer to include TriX and N-Quads too. Holger On 8/04/2020 17:50, 'Bohms, H.M.

On 7/04/2020 12:01, Holger Knublauch wrote: Hi Adam, I am not aware of decent support for Trig within TBC. The issue is that each named graph that can be referenced by TB requires a file in the workspace. So even if we were to load the quads into a TDB, we'd still need to add code that produces TDB connector files (.xdb). Or, split it into multiple TTL files. In the latter case, I guess a 3rd party tool could be used too. For the time being, I have filed an internal development ticket (reference: TBS-2841) to improve on that in the future. BTW this is now implemented and will be part of TBC 6.4. It will take a TriG file and produce Turtle files for each sub-graph. From TBC you could then use project upload to get the data into EDG. This is for TBC only at this stage as it's common that some post-processing may be needed, e.g. to clean up the default graph. Holger Do you have any work-around in the meantime?

Since I've become so used to doing my development work in TBC, I'd very much like to find a way to work with them. Searching this list and the web, I don't get the feeling that there are many options but I thought it would be worth asking. One idea I had is to try and import a TRIG file into a Jena TDB (using Import->Import RDF Files into new TDB) but this results in an exception from deep within Jena (see below). This happens with any of the examples from the TRIG spec. Running on 6.3.0. I'm curious what other approaches I might want to investigate. My ultimate goal is running SPARQL queries across the named graphs defined in the TRIG files. --- Reason: java.lang.NullPointerException at org.apache.jena.ext.com.google.common.base.Preconditions.checkNotNull(Preconditions.java:882) at org.apache.jena.ext.com.google.common.cache.LocalCache.getIfPresent(LocalCache.java:3948) at org.apache.jena.ext.com.google.common.cache.LocalCache$LocalManualCache.getIfPresent(LocalCache.java:4859) at org.apache.jena.atlas.lib.cache.CacheGuava.containsKey(CacheGuava.java:81) at org.apache.jena.atlas.lib.cache.CacheSetImpl.contains(CacheSetImpl.java:72) at org.apache.jena.tdb.store.nodetable.NodeTableCache.cacheLookup(NodeTableCache.java:176) at org.apache.jena.tdb.store.nodetable.NodeTableCache._idForNode(NodeTableCache.java:141) at org.apache.jena.tdb.store.nodetable.NodeTableCache.getAllocateNodeId(NodeTableCache.java:91) at org.apache.jena.tdb.store.nodetable.NodeTableWrapper.getAllocateNodeId(NodeTableWrapper.java:40) at org.apache.jena.tdb.store.nodetable.NodeTableInline.getAllocateNodeId(NodeTableInline.java:51) at org.apache.jena.tdb.store.nodetupletable.NodeTupleTableConcrete.addRow(NodeTupleTableConcrete.java:85) at org.apache.jena.tdb.store.bulkloader.LoaderNodeTupleTable.load(LoaderNodeTupleTable.java:106) at org.topbraidcomposer.tdb.wizards.loader.Loader$StreamRDF_TDBLoad.quad(Loader.java:172) at org.apache.jena.riot.lang.LangTriG.emit(LangTriG.java:266) at org.apache.jena.riot.lang.LangTurtleBase.emitTriple(LangTurtleBase.java:486) at org.apache.jena.riot.lang.LangTurtleBase.objectList(LangTurtleBase.java:352) at org.apache.jena.riot.lang.LangTurtleBase.predicateObjectItem(LangTurtleBase.java:288) at org.apache.jena.riot.lang.LangTurtleBase.predicateObjectList(LangTurtleBase.java:269) at org.apache.jena.riot.lang.LangTurtleBase.triples(LangTurtleBase.java:250) at org.apache.jena.riot.lang.LangTurtleBase.triplesSameSubject(LangTurtleBase.java:191) at org.apache.jena.riot.lang.LangTriG.bracedGraph(LangTriG.java:213) at org.apache.jena.riot.lang.LangTriG.oneNamedGraphBlock2(LangTriG.java:137) at org.apache.jena.riot.lang.LangTriG.oneTopLevelElement(LangTriG.java:49) at org.apache.jena.riot.lang.LangTurtleBase.runParser(LangTurtleBase.java:91) at org.apache.jena.riot.lang.LangBase.parse(LangBase.java:41) at org.apache.jena.riot.RDFParserRegistry$ReaderRIOTLang.read(RDFParserRegistry.java:191) at org.apache.jena.riot.RDFParser.read(RDFParser.java:352) at org.apache.jena.riot.RDFParser.parseNotUri(RDFParser.java:342) at org.apache.jena.riot.RDFParser.parse(RDFParser.java:291) at org.apache.jena.riot.RDFParserBuilder.parse(RDFParserBuilder.java:506) at org.apache.jena.riot.RDFDataMgr.parseFromInputStream(RDFDataMgr.java:870) at org.apache.jena.riot.RDFDataMgr.parse(RDFDataMgr.java:693) at org.topbraidcomposer.tdb.wizards.loader.Loader.loadFromFiles(Loader.java:107) at org.topbraidcomposer.tdb.wizards.loader.TDBLoaderWizard$1.run(TDBLoaderWizard.java:76) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:119) Take care, Adam -- You received this message because you are subscribed to the Google Groups "TopBraid Suite Users" group.
