Description

From users@ email, after the configuration sorted out.

Hierarchies of models, such as inference models, on top of a TBD2 backed-graph do not pass down the transaction leading to

Example configuration (full version attached):

:service  a                   fuseki:Service ;
        fuseki:dataset                :dataset ;
        ...

## Wrapper: Datset containing one TDB2-backed graph
:dataset a ja:RDFDataset ;
    ja:defaultGraph       :graph .

##  TDB2-backed graph
:graph rdf:type tdb2:GraphTDB ;
    tdb2:dataset :datasetTDB2 .

## TDB2 database
:datasetTDB2 rdf:type tdb2:DatasetTDB2 ;
    tdb2:location "DB2".
