How many extensions?

A question that has occurred to me during the discussion of the ‘bibliographic extension'. Is there any benefit/disadvantage in terms of how many extensions are added. For example are there benefits/disadvantages to proposing a ‘comics’ extension which is separate to a ‘books’ (or even ‘bib’) extension.

My guess is that the benefits of minimising the number of extensions relate to ease of managing/maintaining the extensions, but the disadvantages are around community input and cohesion.

Are we sure that a single ‘bib’ extension is what is needed, or would we be better served by breaking this down into a series of extensions?

This work is now close to being ready for release.  Dan has indicated that this provides an excellent opportunity for a bibliographic extension to be one of, if not the first, enabled and released in this way.  In preparation for this, Dan Scott and I have put together a candidate set of types and properties that could constitute an initial bib extension release, which this email introduces.

To take advantage of the opportunity to release along with the capability release, however, we need to agree a starting subset fairly quickly.  To that end Dan and I have drawn up this initial (1.0) proposal consisting of what we believe to be things that are fairly noncontroversial.

They are in three independent groups of proposals, for general bibliographic markup; some helpful things for the physical structure of archives & basic collections; and for comics.
