[Handle-info] OpenHandle: JSON

["Hammond, Tony" <t.hammond@nature.com>]

Hi:

Just wanted to share a couple demo JSON serializations of a handle record
(<info:hdl/10101/nature>) for comment [1], [2].

The first one [1] is a hand transcription of the RDF/N3 [3] - seems to parse
OK with Rhino. It includes namespacing (rdf, handle) and a notation for
declaring namespaces ("@prefix") which are not supported by JSON.

A second version [2] sans namespaces (and excluding the rdf: properties,
here just rdf:type) leads to a more streamlined look and is copied below.

The examples are based on <info:hdl/10101/nature> and include fictional
reference info for demo purposes.

I guess the real problem with JSON would be "difficult" data types - strings
that would need encoding, although should be reasonably straightforward [4],
[5].

char
    any-Unicode-character-
        except-"-or-\-or-
        control-character
    \"
    \\
    \/
    \b
    \f
    \n
    \r
    \t
    \u four-hex-digits

Cheers,

Tony
