I'd avoid data base solutions for footprints, symbols, simulation models and 
the like. 

* Unless there are excellent import/export functions, a data base is an 
additional obstacle to collaboration. These functions need to be written and 
maintained-

* Only a very small subset of the operations available on file systems is 
present by default in data bases. Just to get the same level of user power 
as with files, a major effort of data base scripting is needed.

* A data base can easily be corrupted on update of the data base driver. 

* Open source data base drivers like postgres or mysql may be quite mature. 
Compared to the stability of the unix file utils they still look shaky. And 
fast moving.

* A data base would add a major dependency to the already significant set.

* The number of all objects in the library is fairly moderate. All symbols 
and footprints from the distribution plus all of gedasymbols are currently 
about 4300. This can easily be handled by a file system.

Just my two euro cents.
