Paolo Castagna commented on JENA-63:
------------------------------------
Thanks for the feedback, please, have a look at the two new patches for ARQ and
TDB.
DatasetAssembler now has two methods:
- public final Object open(Assembler a, Resource root, Mode mode)
- public Dataset createDataset(Assembler a, Resource root, Mode mode)
DataSourceAssembler has:
- public Object open(Assembler a, Resource root, Mode mode)
- public DataSource createDataSource(Assembler a, Resource root, Mode mode)
- public Object createTextIndex (Dataset ds, Resource root)
DatasetAssemblerTDB extends DatasetAssembler and ovverrides createDataset
instead of open.
However, I was not able to make DataSourceAssembler.open final.
DatasetAssemblerTDB uses TDBFactory to create a Dataset, I did not find a way
to create a DataSource with TDBFactory. Therefore open in DatasetAssembler is
dealing with datasets while open in DataSourceAssembler is dealing with
datasources.

> It is possible (although not easy for users) to use LARQ with TDB and Fuseki.
> This is to make possible and easy to use LARQ with TDB datasets and with
> Fuseki.
> One way to achieve this is to improve DatasetAssemblerTDB in TDB as suggested
> by http://markmail.org/thread/r5phyiuqkqsyi2xc. This way, LARQ will be loaded
> and wired into ARQ if present in the classpath. Uses will need just to add
> the LARQ jar to their classpath (or depend on it if they use Maven).
