Does 10gR2 Jena Adaptor support SPARQL(W3C) queries with FILTER conditions?

617912Jun 23 2010 — edited Jun 28 2010
I have a SPARQL query with some filter conditions. When i try to execute it against an Ontology persisted in Oracle DB using Jena adaptor (for 10gR2), the sem_match query that is generated does not have the conditions specified (in my case a regex is expected). Is ther no support for FILTERs or am I going wrong somewhere?

Also, wanted to know which API (Jena API OR Oracle Jena Adapter) does the transformation from W3c standard SPARQL to the oracle specific PLSQL procedure?

Thanks,
Rajesh.

Moin!

I did also download the most recent (DVD) ISO did a setup_install_server
and didn't have that problem. I did however skip the burn step and instead
mounted the ISO directly via loopback devices:

# lofiadm -a /jumpstart/OS/isos/sol-10-u2-ga-sparc-dvd.iso
/dev/lofi/7
# mount -F hsfs -o ro /dev/lofi/7 /mnt/10u2

When looking at the files system of this mount the Boot directory is not
linked and as said the setup_install_server worked fine.

Hope this helps

Correct. The CD is a bit low on space, so the boot files are only present in a SPARC UFS filesystem (necessary so the CD is bootable). The x86 box won't read that filesystem (either from CD or from an image).

You'd need to either build at least one SPARC machine, mount the CD there, then copy the files over to the x86 box.

Or as mentioned, use the DVD image. The space there allows the boot code to be duplicated in two places so the x86 box can read it.
