Hi Chris,

The aliases you can use are 1) those that are pre-defined or 2) those that can be declared on a per-query basis, if supported by the query language you're using.

iTQL and SPO don't support per-query alias declarations.  RDQL does, via the USING clause -- see http://www.hpl.hp.com/semweb/doc/tutorial/RDQL/#URI%20Prefixes  

We hope to eventually support the SPARQL language as it matures, and it also has a provision for per-query aliases ("prefix" declarations, I believe they call them).

Subject: [Fedora-users] Resource Index question #3

Hello,

The "alias" capability is implemented in ResourceIndexImpl.java but
there doesn't seem to be any web services interface for an application
to register an alias for a namespace that it uses. This means that
queries must be written in terms of fully spelled out property
designations.

Is there a programmatic means of registering an alias for a user defined
namespace?

Thanks, Chris
