Yesterday, I
wrote about the different representations I want to have available in the BDL.
Perhaps a clearer statement of the BDL's scope is that everything of relevance
to Bach should be either be directly contained by the BDL or would referable
from the BDL. There is no way a BDL can subsume all the wonderful resources
that others are developing about Bach. However, it would be great if the BDL
could know about these other resouces and "interoperate" with them
so that it would be easy for someone to make the best use of all these materials
together.
