Dear Wiki[media] researchers,

this mail is to announce the release of the current, intermediate state of SWiM, a semantic wiki for mathematics. Based on the semantic wiki IkeWiki (http://ikewiki.salzburgresearch.at), which is similar to the better-known Semantic MediaWiki but offers a better RDF and XML infrastructure and a more flexible user interface, SWiM adds support for the following mathematical markup languages:

* MathML, a W3C standard in its upcoming version 3, is used for presenting mathematical formulae. * OpenMath (http://www.openmath.org) is used to enter mathematical formulae in a semantically reasonable structure, regardless of how they are rendered. * OMDoc (http://www.omdoc.org) is used to embed formulae into documents and to semantically structure these documents into mathematical theories and statements.

Note the difference to wikis supporting LaTeX formulae: Here, we chiefly care about the _semantics_ of mathematical knowledge and how to benefit from these structures, and only in a second step about the visual appearance of formulae.

New features in 0.2 are:

1. a completely redesigned and improved user interface, mostly thanks to the hard work Sebastian Schaffert did on IkeWiki

2. rendering of mathematical formulae in MathML 3, according to notation definitions for symbols that can dynamically be made inside the wiki, using the mmlproc renderer (http://kwarc.info/projects/mmlkit/).

3. a way to edit OMDoc XML structures as tables and OpenMath content-markup formulae in a linearized ASCII notation inside the TinyMCE HTML editor (http://tinymce.moxiecode.com)

4. import and export working for OMDoc documents, and partly working for OpenMath content dictionaries and MathML 3 notation definitions.

For the next milestone, I'll mainly be working on enhancing the OpenMath support, e.g. turning SWiM into a proper editor for OpenMath content dictionaries. For technical details, see the roadmap at https://trac.kwarc.info/swim/roadmap.

Check out …

* the live demo at http://swim.kwarc.info * the project homepage at http://kwarc.info/projects/swim/ for further information, downloading an installable packags or the sources, and recent publications. * the bug tracker at http://trac.kwarc.info/swim/ to report bugs or to request features * the SWiM mailing list at http://lists.jacobs-university.de/mailman/listinfo/project-swim and the MathWeb wiki page at http://mathweb.org/wiki/SWiM for more announcements and to participate in detailed discussions.

Best,

Christoph
