SWAML, pronounced [swæml], is a research project around the semantic web technologies to publish the mailing lists' archives into a RDF format. It has been developed by the CTIC Foundation and the WESO-RG at University of Oviedo (Spain). You can visit the project page at BerliOS for more details.
SWAML process description
SWAML reads a collection of email messages stored in a mailbox (from a mailing list compatible with RFC 4155) and generates a RDF description. It is written in Python using SIOC as the main ontology to represent in RDF a mailing list.
