[oslc-core] Enhancing OSLC Query filtering

[Arthur Ryman]

Dragos,

There is a full text search mechanism. oslc.searchTerms [1]

The query syntax was intended to be simple and relatively easy to 
implement. For complex queries, we should use a standard query language, 
e.g. SPARQL. So rather than enhance the simple query syntax, we should be 
promoting query based on SPARQL, e.g. from an index.

Hey all, 

the  oslc.where parameter of OSLC queries allow filtering data using basic 
operators. In some cases this is not sufficient as expressing conditions 
using basic operators is either not possible or very cumbersome. Can the 
OSLC Query be enhanced with some common used predicates such as "like", 
"contains" etc? An example is searching for all the resources that contain 
a specific word in their dc:title property. 

Regards, 
     Dragos
