RDF vs JSON: Which format to use in POD apps

[cdawei]

RDF:

• Pros: Good for sharing data as terms / concepts are defined in some ontology.
• Cons: The app developper has to create their own ontology and make it public if they want to use custom concepts.

JSON:

• Pros: Native support in most widely used languages.
• Cons: Need a "schema" for terms / concepts used when sharing files to others.

For example, in the keypod app, it seems clear to use JSON and store something like below usually won't cause any problem.

{[{"key": "ACT", "value": "Canberra"}, {"key": "NSW", "value": "Sydney"}]}

In other words, some trade-off between being more precise (RDF) versus being more convenient and efficient (JSON).
