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
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>
