Mephisto stands for MEshing People, Hardware and Software TOgether. Mephisto supports collaborative linking of data about software, hardware and people, with the goal to:

• track bugs more efficiently across various bug trackers,
• solve technical issues collectively,
• get accurate information on hardware compatibilities,
• monitor engineering process and tasks,
• more generally to interlink the heterogenous information systems dealing with software, hardware and people, using semantic Web technologies.

Mephisto consists of:

• A set of ontologies used for modelling the business domain of software engineering,
• A set of data extractors exposing existing data as RDF,
• A Web annotator and browser for adding metadata to online discussions, bugs, hardware components, people, documentation etc.,
• A KDE annotator and browser,
• An RDF backend for storing the annotations.
