Make RDF schema and URL's/URI's consistent

Description (Last modified by ronald)

Need to gather up all RDF schemas being used, both our own and external, get an overview of it all, and make sure it's consistent, proper, and documented.

At the same time, we need to gather up all URI's/URL's being used everywhere (in RDF, XACML, etc) and make them consistent, documented, and globally unique. Part of that are the discussions on:

  • URI vs URL
  • # vs /

The use of Kowari models also needs review, especially in light of which models are internal only and which may be subject to public access in the future.

  • description changed.

  • priority changed from unassigned to critical.

One of the problems is that we cannot make these package private or protected as these will be used across multiple packages/services. I am afraid these will have to be pulled out into a separate library for starters with useful functionst to allow different services/packages to have access. Mildly problematic in the sense that it is useful to see the URL when editing/modifying code and now another file will have to be looked at, I think this is less of an issue than having URI's spread everywhere in code and the mess of having to change and deal with it.

We are not going to deal with this now, but this is critical post-launch.

  • owner changed from somebody to pradeep.

What are the consequences of moving to the OTM layer for this?

Replying to amit:

The OTM doesn't change anything - this is a schema problem (we still have to specify the schema with OTM and still have to define the URI's). The OTM will hopefully allow us to focus more time on the actual schema definition instead of the nitty gritty iTQL etc.

:) Let me rephrase. What should/could we do in OTM to make it easier to manage this?

  • version changed from 0.5-SNAPSHOT to 0.8.
  • milestone changed from TBD to 0.8.

06/20/07 15:51:00 changed by amit

  • owner changed from pradeep to ebrown.
  • priority changed from critical to medium.

This is related to the OWL dump work done by Eric and needs to be handled there.

Indeed there are a few bugs introduced because of otm changes. I'll check in fixes shortly.

But as discussed in a few emails in April, this stuff is dependent on a number of mulgara fixes which we have not yet taken:

We can of course merge the mulgara head -- or cherry pick.

I don't think this is needed on production. Any machine that can dump the object definitions will probably suffice. (i.e. The ability to dump the schema isn't needed in production.) Thus, we could branch our own version of mulgara and merge with the mulgara's head and make that available to plos or whoever else wants it. However, I'd suggest closing #417 first.

07/09/07 10:44:00 changed by amit

I don't think there is a direct dependency on #417 as that is a nice to have. I agree that we do not need Mulgara on the production system so that can wait too. Let's use an internal build on Mulgara (from svn of Mulgara.org) to do the testing for now so at least we can give them an option.

07/14/07 11:37:55 changed by amit

  • priority changed from medium to high.
  • version changed from 0.8 to 0.7.

Moving this up to to ensure that the OWL stuff works to provide the content model information to PLoS. Please test this on your Mulgara build and then we will figure out when to move to it for production purposes.
