AW: 回复:AW: About metadata implementation

Dear Jianbin,

if I understand you are defining your own ontology, rather than what this WG is proposing. We'd be interested to know the reasons why our proposed ontology is not suitable for you.

Concerning the representation: if you look at the examples of our API document, JSON is a representation we consider relevant for the client-side API.

Best regards,
Werner

Thanks Werner!
Yes, we are working the ontology for media resource, very much like media annotation group's work. But we have some properties that could contain very flexible values, such as a set of weighted keywords which best describe the content. The problem is to find a right representation method that supports modification and search well. Options I can think of are, xml and supported databases, JSON and CouchDB/MongoDB, Or Key-value Pairs (not sure
 if it's feasible). I would love to hear any suggestions.
Thanks.

Jianbin
