16 <p> Matita is a new document-centric interactive theorem prover that
17 integrates several <a href="http://www.mkm-ig.org">Mathematical Knowledge
18 Management</a> tools and techniques. </p>
20 <p> Matita is <strong>traditional</strong>. Its logical foundation is the
21 Calculus of (Co)Inductive Constructions (CIC). It can re-use
22 mathematical concepts produced by other proof assistants like
23 <a href="http://coq.inria.fr">Coq</a> and encoded in an
24 <a href="http://www.w3.org/XML/">XML</a> encoding of CIC. The interaction
25 paradigm of Matita is familiar, being inspired by CtCoq and
26 <a href="http://proofgeneral.inf.ed.ac.uk/">Proof General</a>. Its
27 proof language is procedural in the same spirit of LCF. </p>
29 <p> Matita is <strong>innovative</strong>: </p>

42 the user interface sports high quality bidimensional rendering of
43 proofs and formulae transformed on-the-fly to <a
44 href="http://www.w3.org/Math/">MathML</a> markup, on which direct
45 manipulation of the underlying CIC terms is still possible;

64 the knowledge base is distributed: every authored concepts can be
65 published becoming part of the Matita library which can be <a
66 href="http://helm.cs.unibo.it/browse/">browsed as an hypertext</a>
67 (locally or on the World Wide Web) and <a
68 href="http://helm.cs.unibo.it/whelp/"> searched by means of
69 content-based queries</a>; </p>

79 the tactical language, part of the proof language, has
80 step-by-step semantics, enabling inspection and replaying of deeply
81 structured proof scripts. </p>
