RDFa added to Copac records

Copac record displays now included RDFa markup. This should make our record (or metadata if you prefer) displays more machine readable.

You should see no difference in our record displays (unless some bug has been disturbed somewhere.) However, you can reveal the RDFa by giving one of our record displays URLs to the W3C RDFa Validator. If you do that you’ll see that we have used a variety of vocabularies in encoding our data. An example of the type of output you get from the Validator is shown below in Turtle format.

<http://copac.ac.uk/crn/013797505> a schema:CreativeWork;
    isbd:P1045 "With 85 photographs by the author."@en;
    isbd:P1053 "120 p. : illus. ; 29 cm."@en;
    schema:about "History"@en,
        "Peak District (England) — Pictorial works."@en,
        "The Peak, Eng."@en;
    schema:author [ a schema:Person;
            schema:name "Poucher, W. A. (William Arthur)"@en ];
    schema:datePublished "1946."@en;
    schema:inLanguage "English"@en;
    schema:name "Peak panorama : Kinder Scout to Dovedale."@en;
    schema:publisher [ a schema:Organization;
            schema:name "Chapman & Hall,"@en ] .

The primary vocabulary is schema.org, though where our metadata couldn’t be squeezed into schema.org we’ve used other vocabularies. The full list is as follows:

I don’t know of any user applications that can make use of RDFa yet. I was hoping Zotero might be able to harvest the RDFa, but it doesn’t seem to be able to. So if anyone knows of anything that can make use of the RDFa in our record displays, please get in touch.

We’d also be grateful to know if you think this is a useful addition to our records, how it could be improved and if you think you’ll use it.
