Hi Eric,
I think the problem comes down to this part of the config:
> <#minimalDataset> rdf:type ja:RDFDataset;
> ja:defaultGraph <#minimalGraph>.
>
> <#minimalGraph> rdf:type tdb:GraphTDB;
> tdb:location "/home/escott/TDB/minimal/".
Can you use:
<#minimalDataset> rdf:type tdb:DatasetTDB ;
tdb:location "/home/escott/TDB/minimal/".
instead?
The way to have it set up, the graph isn't transactional because it's in
inside ja:RDFDataset.
ja:RDFDataset means an in-memory general purpose dataset that can
contain any sort of graph including a mixture of graphs from different
storage systems or inference engines. It does not support transactions.
tdb:DatasetTDB is a dataset directly backed by TDB and does support
transactions.
I've found the cause of your specific problem aad applied a specific fix
but other things will go wrong when using an in-memory dataset (e.g. if
you add a new graph via SPARQL Update).
The best solution is to use a TDB dataset directly by using tdb:DatasetTDB.
