[Pellet-users] Importing SPARQL in Jython?

[Margaret A Mitchell]

Thanks!  Unfortunately, SETH only works with Java 1.4, which is outdated.  Every system I have access to is 1.6, which Seth doesn't seem to be able to handle...

I think I have to default to creating a query text file and calling the command line from Python, where I feed the query to Pellet that way...The only problem with that is it's much slower, so if anyone has any better ideas, let me know! =)

Thanks,
M
