Hey guys,
recently i've been reading about this no-sql database OrientDB and it seems quiet appropriate to storage tiddlers in the same way that they exist,
being a Document-Graph db it can handle relations like tags-generated ones also.
As full-time student i do not have so much free time to work on it but i consider it a good new connector.
Please check it out and i'll keep you update on my efforts.
Greetings!
