From the website:

Isidorus is an Open Source Topic Map engine actively developed using sbcl and elephant. Isidorus supports import and export of XTM 1.0 and 2.0, full versioning, merge semantics, an Atom-based RESTful API and Topic Map querying — with more to come.

Current areas of development include:

  • Enforcements of constraints (TMCL)
  • Json-import / export and a AJAX front end for data curation
  • Enhanced querying

Also note:

A Virtual Box image of a pre-installed isidorus-environment on an Ubuntu-Linux system is available at:
