OCLC came up with the 'Library' ontology as a provisional extension for the
WorldCat work: http://www.essepuntato.it/lode/http://purl.org/library/

In retrospect we probably should not have created a load of classes for
carrier types - a more pragmatic solution may be found by making use of
Schema's external enumerations
<http://blog.schema.org/2012/05/schemaorg-markup-for-external-lists.html>

Removing those from the list the number of object properties
<http://www.essepuntato.it/lode/http://purl.org/library/#objectproperties>
and data properties
<http://www.essepuntato.it/lode/http://purl.org/library/#dataproperties> is
very short.

I would suggest that we don't constrain our thinking to any [currently held]
record format - Marc/RDA/Onyx etc.  But consider the things we describe in
those formats - Books, Articles, Journals, Theses, and their associated
People, Organisations, Places, Concepts, Events, and Annotations.

If it makes sense to describe the colour of paper used for a book, the fact
that there is no Marc tag for it should not prevent us from recommending it.
([hopefully] fictitious example, not a basis for a new email thread ;-)

It is then up to us to back up such a recommendation with examples and
recipes of how you would use that data (in current formats if you have it)
and represent it in Schema.
