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>

+ 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

-resources at the general-purpose content level.<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>

- 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>

- Other languages to be developed in the context of the MathQL proposal will
- be suitable for queries about the semantic structure of mathematical data:
