Andy Seaborne commented on JENA-988:
------------------------------------
It is possible to do this by simply testing for the presence of the directory
where the store might be in the usual java way.
There is some private code {[DatasetBuilderStd.isNewDatabaseArea}} that takes a
pragmatic approach. It uses {{File.exists}} and tries to look for "tdb.cfg".
But because older versions of TDb did not have a configuration file, full
reliable testing is not possible.
