+ The MathQL proposal rises in the context of the <a
+ href="http://helm.cs.unibo.it/">HELM project</a>, which aims at the development
+of a suitable technology for the creation and maintenance of a virtual,
+distributed, hypertextual library of structured mathematical knowledge
+based on <a href="http://www.w3.org/XML/">XML</a> technology, through the
+ integration of the current proof assistants and logical frameworks with
+the most recent technologies for the development of Web applications and
+electronic publishing.<br>
+ <br>
+ 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. The first of these languages,
+ <b>MathQL-1</b>, is focused on querying an arbitrary <a
+ href="http://www.w3.org/RDF/">RDF</a> database because RDF is the <a
+ href="http://www.w3.org/">W3C</a> standartd for describing Web resources
+at the general-purpose content level.<br>
+ <br>
+ As an RDF query language, MathQL-1 provides the main features required
+ by the RDF community while complying with the needs of HELM. The peculiar
+ aspects of this language concern the query results, which are highly structured
+ and possess their own syntax, formally explained by a rigorous semantics.<br>
+ <br>
+ MathQL-1 is particularly helpful in distributed systems where query
+ engines are implemented as stand-alone units, because in this situation
+ the query results are exchanged between the system components as well as
+ the queries, and thus both the queries and the query results need to be
+encoded in a clearly defined format.<br>
+ <br>
+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).<br>
