New MaJorToM Topic Map Store based on redis

Published by {{by}} on {{at}} and updated at {{updated}}.

Abstract:

Today we added a new backend to the powerful Topic Maps engine MaJorToM: the Redis Topic Map Store. Redis is an open source, advanced key-value-store supporting strings, sets, hashes and lists as values. The code is published at the MaJorTom Google Code project.

The new topic map store is the perfect combination of a light-weight and persistent data store. It enables a parallel access without the need to implement own thread locking mechanism. Redis is easy to administrate and enables very fast read and write access. Additionally it allows replication to multiple servers using its built-in sharding functionality.

To make a topic map storage within a Redis database, we recreated the schema of the Topic Maps Data Model based on the Redis possibilities. The Schema is documented . We are looking forward for comments on both the Redis store and the schema.

Update 2011-04-14: Johannes Schmidt has published another proposal for mapping of the Topic Maps Data Model to Redis schema.

In Musica migrans we mapped the life courses of musicians in the 19th century. Topic Maps provides us the flexibility we need to model the diversity in the lives of the artists.
