unAPI format and Semantic Web

Ross Singer's recent post about "One Data Format Identifier (and Registry) to Rule Them All" caused some interesting discussions. I didn't read all of them, and don't have much to add, but I do have a chance of reflecting how unAPI format wiki was created at the first place.

It turned out that I always have trouble of understanding why Semantic Web is so obsessed with URI and Ontology. I am not Semantic Web expert, but to me the strict URI approach seems to directly conflict with other "convention over configuration" approaches like tagging, wiki, twitter. And it doesn't seem everyone will have the time to learn each other's ontology anyhow. As a result, any sufficiently large RDF file always make my head spin because of all these long URIs, and I am not sure how much bandwidth were used to carry them on the Internet.

So why don't just use a word as the identifier, and let everyone pickup a dictionary and find out its semantic. I guess Oxford dictionary is a better agreed-upon ontology. In retrospect, perhaps this is how unAPI format differs from SRU/OpenURL, we can choose a name and hopefully it will work. Does it work? I don't know.

Since multiple copies keep stuff safe, I also paste here the unAPI format retrieved from Internet Archive.
