That's why mainstream IT ignores the SW.    (03)

Tim B-L's proposal from 2000 went far beyond that.  RDB2RDF does not
support interoperability -- it is designed to copy RDBs into RDF
and run everything from a triple store.  Interoperable systems
must be able to interoperate dynamically.    (05)

With true semantic interoperability, you don't put facades on data.
The data formats and they way they're stored are totally irrelevant.
Data from any source, stored in any format whatever, should be usable
according to its semantics, not its syntax.    (07)
