Re: SPI DatasetGraph creating Triples/Quads on demand using DatasetGraphInMemory

Hi. I've pushed up a draft to https://github.com/dick-twocows/jena-dev.git. This has two test cases; Echo : which will echo back the find GSPO call i.e. call find ABCD and you will get the Quad ABCD back. This does not cache between calls. CSV : which will transform a CSV file into Quads i.e.

I guess you could use addGraph to intercept and alter (or substitute) the graph, but that seems like a real distortion of the semantics. Seems like the AFS-Dev material is more to the point here. Andy, what do you think it would take to get that stuff to Jena master? Do you think it is ready

Eureka moment! It returns a new Graph of a certain type. Whereas I need the graph node to determine where the underlying data is. Cheers Dick. On 15 March 2016 at 11:28, Andy Seaborne wrote: > On 15/03/16 10:30, Dick Murray wrote: > >> Sorry, supportsTransactionAbort() in

I wrote the DatasetGraphInMemory code, but I suspect your question may be better answered by other folks who are more familiar with Jena's DatasetGraph implementations, or may actually not have anything to do with DatasetGraph (see below for why). I will try to give some background
