Bug 6594: Schema.org structured data for OPAC display
To support schema.org processors, such as Google, Bing, and Yandex, structure our data so that it has machine-readable attributes. This pass declares the CreativeWork sub-types as well as Product for the main bibliographic record details, and uses the Offer type for holdings information per the W3C Schema Bib Extend community group discussions. Signed-off-by: Dan Scott <dan@coffeecode.net> Signed-off-by: Jared Camins-Esakov <jcamins@cpbibliography.com> Comments on final patch. Signed-off-by: Chris Cormack <chris@bigballofwax.co.nz> Signed-off-by: Galen Charlton <gmc@esilibrary.com>
