From the announcement:
CouchTM – the topic maps engine with CouchDB as backend – is released.
Apache CouchDB is a document-oriented database that can be queried and indexed in a MapReduce fashion. According to the website CouchDB is:
- A document database server, accessible via a RESTful JSON API.
- Ad-hoc and schema-free with a flat address space.
- Distributed, featuring robust, incremental replication with bi-directional conflict detection and management.
Inspired by the increasing impact of NoSQL approaches like CoucDB we developed CouchTM. This a TMAPI topic maps engine which uses the CouchDB as backend. CouchTM can be used like any other Java based topic maps engine. Hans-Henning Koch’s Bachlor thesis provides more information about CouchTM (in German). CouchTM as well CouchDB are available as open source.
BTW, don’t look for the files under Downloads but rather under Source. (as of 4/21/2011).
