Sadhu! for your aspiration. As Buddhists have known for a long time,
and the rest of the world is just starting to learn, having masses
of information is no use if there's no way to organize and make
sense of it.
It's interesting to reflect that Buddhists have often been at the
forefront of information technology. The oldest inscriptions in
India (Asokan pillars) are Buddhist-inspired, as are the oldest
manuscripts, and also the oldest printed documents in the world, a
Chinese version of the Diamond Sutra. Printing was developed, in
fact, to enable the reproduction of the sprawling Chinese Tripitaka.
I have no knowledge of databases, etc. But as those on this list are
aware, i have started a project called sutta-central, which aims to
co-ordinate the material available on the web from various Buddhist
canons. It has a different angle than your idea, since we will not
attempt to supply such details and different ways of seeking texts.
Rather we hope to link up existing resources in different languages.
But i'm sure we could get the two sites to link up together for
mutual benefit.
