Multiple RDF documents

Hi all,

We have been using SKOS to model our data within our HILT project and there
are potential issues with the current model. I am not an expert in SKOS and
I wonder if someone could advice me regarding this. 

A snippet of existing model is like this

http://hiltm2m.cdlr.strath.ac.uk/hilt4/get_filtered.xml   

There are two potential problems with this model

1. A possible id clash within different schemes. As the concepts from
different vocabularies are listed in the same rdf document, referring to a
concept #888 might not be necessarily unique, especially when we search
across multiple vocabularies managed by different organizations.

2. Parsing issue - When these concepts are retrieved as a result of search,
there is no way to identify whether a particular concept has been pulled out
as a result of real search or it is listed because it is a related concept
of a search result. (In the above example, there is no way to identify if
the concept #888 has been retrieved because of search or because it is the
broader term for concept #944)

This is important to know especially when client parses the document.

One of the possible solution we can think is having multiple RDF document
within one xml file like this
http://hiltm2m.cdlr.strath.ac.uk/hilt4/get_filtered_new.xml

I don't know how sensible it is and really appreciate any comment on this.

Thanks

Anu
