Updating the CTS TextInventory schema

Scott Mcphee points out the absurdity of a Canonical Text Service (CTS) definition that uses CTS URNs for all retrieval requests, but doesn't include CTS URNs in the service's TextInventory.  The historical explanation for the inconsistency is embarassingly simple:  the TextInventory schema predates the invention of CTS URNs, and has not been revisited since!  That oversight is rectified with today's release of version 0.12.1 of the CITE schemas package.

Ultimately, we want to arrive at catalog entries with urn attributes that look like this:

<textgroup urn="urn:cts:greekLit:tlg0012">
 <groupname xml:lang="eng">Homeric poetry</groupname>
 <work urn="urn:cts:greekLit:tlg0012.tlg001" xml:lang="grc">
  <title xml:lang="eng">Iliad</title>
  <edition urn=":cts:greekLit:tlg0012.tlg001">
   <label xml:lang="eng">Allen (OCT 1931)</label>

With release 0.12.1, the urn attribute is now optional but strongly recommended, alongside the previous projid attribute.  With release 0.13.0, the urn attribute will be required, and the projid attribute deprecated.  With release 0.14.0, the projid attribute will be dropped.

So grab from our nexus repository to get started with a modern TextInventory identifiying texts by URN.  You can manually download a zip bundle from the repository,  or update your maven coordinates with groupId "edu.harvard.chs", artifactId "cite" and version "0.12.1".

[Updated:  bumped version from 0.12.0 to 0.12.1 after adding trailing slash to dc namespace as requested by Bridget Almas]

Neel, with the next release of the schema can you also correct the dc elements namespace uri? It should be '' with a trailing slash.

Done: make the version number 0.12.1 now, not 0.12.0.
