Re: Some Draft SchemaBibEx Proposals

Hi Gordon,

As Karen mentions, Schema.org purposely avoids the strict definition of
domains and ranges and (as I would put it) 'hopes' to find the Expected Type
as a property but it is also acceptable to find a string representation.

The 'identifier' property I describe in the draft is stretching schema.org
documentation style a little, by adding in an order of preference to the
Expected Type.

You are correct that a URI could be an identifier but the meaning I was
hoping for in this case was that the identifier in question would be a
[Standard] Identifier.  Hence the examples of ISSN, ISNI, etc.

However I omitted the word 'standard' so as not to restrict the use to only
identifiers produced by standards bodies.

So, in my draft I was intending the URI would identify (link to) the
description of a [standard] identifier.

I perhaps need to work a little on my descriptive text - all suggestions
welcome!

~Richard.
