Hmmm... I thought BeOS used this sort of mechanism, mirroring the file
system metastructure in some sort of quasi-relational db in order to
support BQuery objects (which let you ask for all file system nodes
satisfying some set predicate, which can even be expressed as a string
something like the 'where' clause of a SQL 'select'):
This machinery has, I think, been there since Be's first release.
Have they licensed the patent?
