Oops I had an extra } { in the JSON. Also, there are several
_javascript_ parsers for Turtle available which do add a slight
overhead, no big deal to me. Other serializations include
N-triples, RDFa and N3 -- any others? As for XML serialization,
there is a non-striped format (which may be the XML format JSowa
loathes) which is slightly less comprehensible than the striped
format. And my rendition of the striped XML format probably
should've used rdf:about, not rdf:id (actually, it should've been
rdf:ID if not rdf:about).
3. JSON (revised)
{ "http://www.mysemanticwiki.com/wiki/Person:X"
:
{ "http://www.w3.org/1999/02/22-rdf-syntax-ns#type"
:
[ { "value" : "http://www.mysemanticwiki.com/ontology/Nouns.rdf#Person",
"type" : "uri"
}
],
"http://www.mysemanticwiki.com/ontology/is.rdf#this"
:
[ { "value" : "http://www.mysemanticwiki.com/wiki/Man:X",
"type" : "uri"
}
]
}
}

The triple "Person:X is:this Man:X"
has these encodings (from a semantic wiki that requires
all its pagenames to contain a 'type'
prefix). Draw your own conclusions about each
encoding but to me Turtle is superior, followed by XML, and
wiping up the rear would be JSON, because JSON has no text
entity support unlike the other two. And so, fwiw, I think the
claim JSON is a 'lightweight' protocol is somewhat unfounded
plus I'm not crazy about an English-only protocol. Feel free to
correct me if I've missed anything here. thanks/jmc
1. Striped RDF XML
<!ENTITY rdf "http://www.w3.org/1999/02/22-rdf-syntax-ns#">
<!ENTITY wiki "http://www.mysemanticwiki.com/wiki/">
<!ENTITY is "http://www.mysemanticwiki.com/ontology/is.rdf#">
<!ENTITY nouns "http://www.mysemanticwiki.com/ontology/Nouns.rdf#">
<rdf:RDF xml:ns="&nouns;"
xmlns:rdf="&rdf;"
xmlns:is="&is;">
<Person rdf:id="&wiki;Person:X">
<is:this rdf:resource="&wiki;Man:X"/>
</Person>
</rdf:RDF>
2. Turtle
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
@prefix wiki:
<http://www.mysemanticwiki.com/wiki/>
@prefix is: <http://www.mysemanticwiki.com/ontology/is.rdf#>
@prefix : <http://www.mysemanticwiki.com/ontology/Nouns.rdf#>
wiki:Person:X
rdf:type :Person ;
is:this wiki:Man:X
.
