Referencing a model from programming code?

Hi!

I collected some thoughts on how to set up a lightweight semantic
interoperability framework based on OWL and SAWSDL here:

I was unable to find the equivalent of SAWSDL [1] for programming
code. As you may know SAWSDL provides a way to annotate XML schemas
and WSDL artifacts with references to a vocabulary in a standardized
way. Since programming code can be considered a design artifact of a
system it would be great if it was possible to annotate it with
references to a vocabulary. Is there a standard for that? It would
make it possible to keep an unbroken chain of references between many
of the artifacts used in software development.
