I was reading some articles at O’Reilly’s excelent O’Reilly Radar weblog. Then I read this:
Triple tags? Triples, that rings a bell. So I decided to follow the link to the announcement at the flickr site. And guess what do I read?
Still… that reminds me of something… Hmm… So for each picture, you can add any random predicate (property) with a value. So basically you end up with a bunch of ([picture], [predicate], [value]) tuples right. Hmm.
So let me paraphrase this thing. Flickr always has known tags, which could give you some more hints about what the picture was about. Keywords if you will. These were additional pieces of metadata, information about data (pictures in flickr’s case). Right now these tags can be structured, so there is room for a property/field/predicate/whatever-you-want-to-call-it name and a value. And this predicate has a namespace. Hmm. So what they create is a kind of framework to be able to describe pictures. Interesting. Wouldn’t it be a nice idea to generalize this and develop a framework like this to describe any resource?
We could call it, hmm, say… RDF?
