Hi all,
I've got a simple problem and looking forward to a "good" solution.
Hopefully someone can give me a useful hint... ;-)
I've got two TDB backed models both containing several named graphs: A
and B
You mean 2 TDB datasets?
I realise it's obvious and so you probably have good reasons you don't want to
do it, perhaps to do with avoiding duplication - but simply copying all the
data into a single TDB seems the easiest and quickest solution.
Hi Bill,
indeed, that seems the easiest solution, in particular if the two RDF datasets
you want to merge do not receive a lot of updates and you do not mind having
the merged result not updated in real-time with the sources.
If you allow stuff to be added/removed from the original RDF datasets and you
want to keep the merged dataset in sync things become more complicated. In
particular deleting stuff.
