I have some comments to this, which I hope we can discuss at the appropriate session. In brief, as with the classification of books, a classification scheme for subjects and a classification scheme for classes of "Thing", are two separate
matters! I hope we are able to keep this in mind. Let's discuss when we meet.
Best regards,
Mike

Dear all,
Aleksandra Sojic has created a first version of the meta ontology, see
https://github.com/ontohub/OOR_Ontohub_API/blob/master/Domain_fields.owl - use "raw" for downloading and viewing with Protégé:
https://raw.github.com/ontohub/OOR_Ontohub_API/master/Domain_fields.owl
This ontology provides a meta-classification that according to the domain subjects distributes domain-ontologies into the domain-specific classes. As the reference classification we have considered several international standards which are used to classify
domain fields. The International Standard Classification of Education (ISCED) has been selected as the most appropriate reference for the specification of the (subject) categories within the OntoHub. ISCED is a member of the United Nations International Family
of Economic and Social Classifications and is the reference classification for organizing education programmes and related qualifications by levels and fields of education (ref. ISCED). In particular, we have used the last version of ISCED (the final draft
published in June 2013) as it provides a hierarchy of knowledge domains suitable for covering comprehensively the corresponding ontology-modelling fields.
The Domain-fields-ontology has to be developed further in order to include several other specifications, especially considering the domains which experience a significant expansion in the ontology development, e.g. Life Sciences.
Please find attached a graphical visualisation of the recently published Domain-fields ontology.

Watching this thread, and interested as well...do you have a reference
for who is heading this up?

Oliver,
Worth pointing out is that we (the NCBO team) don't feel that the
current
BioPortal categorization is very good. It should probably not be used as
the basis for anything. There are external efforts to produce a
categorization system for the biomedical domain. We aren't taking
the lead
in this categorization effort but if a standard (defacto or not) does
arise we would be interested in adapting our system to use it.

Subject: Re: [oor-forum] Categories for ontologies
P.S.
the interesting question is then: what happens if we federate BioPortal
with SOCoP? We need a taxonomy including all the involved
categories, such
that in the ontology browser, all the BioPortal categories are combined
into one category "biology" (which can be expanded into the BioPortal
categories on demand).
