As I didn't find anything related, I would not use anything.

In DOAP it's like this:

The domain of doap:revision is doap:Version, which is in range of 
doap:release.

So we could have the following triples:

<#foo> rdf:type earl:Software
<#foo> doap:release <#bar>
(<#bar> rdf:type doap:Version)
<#bar> doap:revision "1.0"
