Re: [Psidev-ms-dev] more is_a vs. part_of errors?

[Chris T. <chr...@eb...>]

Hiya.

I think deprecation is pretty standard and is implemented for 
PSI CVs iirc. That way a term is not substantively changed, just 
flagged as deprecated with a pointer to the new preferred term 
and therefore nothing breaks (although terms are obviously added 
elsewhere as part of the process, but then they will be being 
added all the time anyway so a frozen CV is not that great an 
idea but updates need not be nightly as say OLS is (again, iirc)).

Cheers, Chris.
