Getting back to the merits of the proposal itself….
Although there are some details that would need to be worked out, I think there is the basis here for an elegant solution to sector specific needs that build upon, yet do not dilute, the value of the core Schema.org<http://Schema.org> vocabulary.
Some of those details that would contribute to the success of this approach are, however, in the hands of the search engines.
We know that Google et al are understandably reticent to share insights into what they do and don’t recognise in data they harvest, yet some indication of what they would do with something defined in one of these extension vocabularies would contribute significantly to the adoption of such extensions.
For example what would they do, or intend to do in the future, with a bib.schema.org/MicroForm<http://bib.schema.org/MicroForm>, or with a bib.schema.org/translationOfWork<http://bib.schema.org/translationOfWork> property associated with a schema.org/Book?<http://schema.org/Book?>
Would they:
* Ignore them both
* Recognise them both for what they describe
* At least recognise the Microform as an instance of CreativeWork (which it is a subtype of)
* ?

Could you help by providing some more realistic examples of cases
where a description mixes core schema.org<http://schema.org/> terms with those from
Bibliograph?
Below are a few examples of live data from OCLC’s worldcat.org<http://www.worldcat.org/> containing some BiblioGraph.net<http://bibliograph.net/> terms mixed with core schema.org<http://schema.org/>, plus a few other bits and pieces. I’ve provided extracts, and include links to the full descriptions, in turtle. (if you prefer other flavours, swap the .ttl suffix for .nt, .rdf, .jsonld, or remove it for the html/rdfa version)

These few examples are from a set of 300+ million bibliographic descriptions in worldcat.org<http://worldcat.org/>, with links to some 200 million Work descriptions derived from the same source. As a work in progress there are still a few issues to resolve both in vocabulary and data terms. However they are an effective live demonstration of using schema.org<http://schema.org/> as a core vocabulary and extending it with BiblioGraph.net<http://bibliograph.net/> - the pattern being proposed for bib.schema.org<http://bib.schema.org/>.
