Re: [Glossary] Definition of a portable document (and other things...)

Leonard,

We agree that WDe is not portable. Your dashboard example is indeed borderline, but I *think* it can not be really qualified as portable, because it cannot do anything offline... On the other hand, if the dashboard is part of a larger Web document that teaches information visualization where the dashboard is an example then it is Portable. The borderline is fuzzy. But I think that, as far as I am concerned, a Portable Web Document is defined by a MUST in the definition below.

I think the question is what the subject of discourse is for digital publishing (and EPUB+Web). It is perfectly ok to have Web documents that are not portable but that, may be, can be transformed into a portable Web document. But I believe that it may be perfectly all right to decide that we concentrate on Portable Web Documents in such a strict sense.

I know this is the one point on which Bill and I disagree, but we have some actual use cases where this comes up.  Also, in my mind, this is the “cached” state for the PWD – where it would normally get something online but when not connected it could/would use something local (but not part of the document).

We had (based on the wiki page on packaging) three 'states', namely the online, cashed, and portable; are we saying that the Portable Web Document is, in fact, a *state* of a Web Document, rather than some sort of a category?
