[uf-dev] JSON representation of semantic objects

Fri Jan 4 14:39:34 PST 2008

Both those seriliazations look remarkably verbose. Why doesn't:
<div class="haudio">
 <span class="fn">Start Wearing Purple</span> by
 <span class="contributor">Gogol Bordello</span>
 found on
 <span class="album">Underdog World Strike</span>
</div>
just map to:
{"fn":"Start Wearing Purple", "contributor":"Gogol Bordello",
"album":"Underdog World Strike"}
instead of the multi-crufted:
{
 "_:haudio1" :
 {
 "http://www.w3.org/1999/02/22-rdf-syntax-ns#type" :
 [
 { "value" : "http://xmlns.com/haudio/1.0/Album", "type" : "uri"}
 ],
 "http://purl.org/dc/elements/1.1/title" :
 [
 { "value" : "Start Wearing Purple", "type" : "literal", "lang" : "en" }
 ],
 "http://purl.org/dc/elements/1.1/contributor" :
 [
 { "value" : "Gogol Bordello", "type" : "literal", "lang" : "en" }
 ],
 "http://xmlns.com/hmedia/1.0/contains" :
 [
 { "value" : "_:haudio2", "type" : "bnode" }
 ]
 },
 "_:haudio2" :
 {
 "http://www.w3.org/1999/02/22-rdf-syntax-ns#type" :
 [
 { "value" : "http://xmlns.com/haudio/1.0/Recording", "type" : "uri"}
 ],
 "http://purl.org/dc/elements/1.1/title" :
 [
 { "value" : "Start Wearing Purple", "type" : "literal", "lang" : "en" }
 ],
 "http://purl.org/dc/elements/1.1/contributor" :
 [
 { "value" : "Gogol Bordello", "type" : "literal", "lang" : "en" }
 ]
 }
}
