+ Goals and features
+
+
+ MathQL-1 is designed to achieve the following goals:
+
+ - Exploitation of RDF technology
+to manage metadata and compliance with the main requirements for an
+RDF query language. In particular:
+
+
+
+ - MathQL-1 provides facilities for hierarchical constraints based
+on RDF Schema and for traversal
+of compound values of properties.
+
+
+ - MathQL-1 provides a full set of Boolean operators to compose
+query constraints and facilities for selecting URI's or literals by means
+of regular expressions.
+
+
+ - MathQL-1 allows to customize the query results specifying what
+part of a solution should be preserved or discarded.
+
+
+ - MathQL-1 has a well-conceived semantics defined in term of
+an abstract metadata model, imposes that queries return exhaustive solutions
+and includes a "select-from-where"-like construction.
+
+
+ - MathQL-1 supports a machine-processable XML syntax as well as a human-readable
+textual syntax to achieve the best usability.
-
-
-
-
+
+
+ - Careful treatment of query results that are as important
+as the queries themselves. In particular:
+
+
+
+
+ - MathQL-1 query results have a 4-dimensional geometry whereas
+other languages assume that query results are returned in 1-dimensional structures
+(ie lists of resources) or 2-dimensional structures (ie relational database
+tables). This allows to get better outcomes from queries returning structured
+results.
