James Amsden commented on OSLCCORE-153:
---------------------------------------

Can we leverage XML semantics here? So in your example, > would would be based on lexical ordering of URIs - not something that would seem to be very useful unless the URIs were in some particular form. But not something it would see OSLC needs to worry about.

> The query syntax for oslc.where supports a query term that uses ">", ">=", "<", or "<=" with a URI value. However, the semantics are undefined.
> For example, what does the following mean, if anything?
>     oslc.where=dcterms:creator > <http://example.com/user/David>
> The only use case I can think of where this might add value is where the value is a URI of an enumeration member. If an enumeration has members defined with rdf:value denoting ordering, then a query such as:
>     oslc.where=cm:severity > cm:Medium
> might be useful. However, the spec does not define how enumeration members might be compared.
