i am looking for arc users and developers. is there anybode here?
16:54:42
bengee is
16:55:24
i just wonder why it is necessary to have a database connection when using sparql on rdf's
16:55:56
arc has a sparql2sql rewriter but not an in-memory processor
16:56:18
ah ok
16:56:56
so its absolutely necessary or is there an alternative?
16:56:57
not yet, at least. feature requests are increasing, so I might have to add one
16:57:38
for simple operations, you can work with ARC's index arrays, but for pattern search, you need the DB
16:57:50
ok, thanks!
16:58:11
np :)
16:59:57
I'm pretty sure a basic in-memory sparql processor could be written during a free weekend, but I don't have any at the moment :(
17:03:54
but why the developers implemented a sparql2sql rewriter in the first place if an in-memory processor whould be so easy
17:05:42
the former was more important. in-memory is for non-persistant and small datasets only, which was not really needed
17:06:29
ah i see...
17:07:05
it's becoming more relevant now, because apps start to do more inferencing and combine data from multiple queries
17:08:46
thats what i'm up to do for a university project...
17:10:06
maybe i have the time to take a closer look and help with the development. if this is possible.
17:11:22
that'd be cool
