For example, what is the difference between axioms and assumptions? (I've asked this before, and I think the answer has to do with whether they are theorems about constants defined by the article or not...) I would like to see a slogan or two to keep in mind about OpenTheory, and a web page (or pdf if necessary) describing semantics (maybe in some logical framework or something). I think a slogan could be "A theory package is a collection of theorems, represented by proofs." - Is that right? But it sweeps two important issues under the rug: definitions and assumptions. Is there an accurate slogan that would deal with these two things and say exactly what a theory package is? Definitions complicate things because I think you need to talk about language extensions and conservative extensions of theories, but all this is presumably standard stuff - I just want to see exactly how OpenTheory embodies it. The semantics I'm looking for may well already exist in a paper somewhere - in that case I'd like to see a link on the project homepage.

Normally there's no way to delete packages and so you'd have to just upload a new version, but since it was the initial upload that contained problems I just reset the whole repo and re-uploaded the fixed version. Hopefully everything is now in order - the lesson here is to CHECK CAREFULLY before uploading!!!

Yes, the example package is excellent!
