A query language for RDF metadata

- + - - - + + - + - - - +
+ The objective of the MathQL proposal is the development of a +set of query languages enabling the retrieval of formalized mathematical +Web resources on the basis of content-aware requests.

+
+ Other languages to be developed in the context of the MathQL proposal + will be suitable for queries about the semantic structure of mathematical + data: this will include content-based pattern-matching (MathQL-2) and possibly + other forms of formal matching involving for instance isomorphism, unification + and definitions expansion (MathQL-3).
