Re: schema.org proposal for extending Thing

Ah, OK I get it now. I'd describe additionalType as allowing you to refer to 'Things' that aren't schema.org 'Things'. Whereas CreativeWork's 'about' property allows you to refer to 'Things' that *are* schema.org 'Things'. I can now see how my category requirement could be expressed using additionalType. 

I'm not sure if there's general consensus that categorization/tagging is properly seen as a typing exercise. Looking forward to comments from the group...
