I’ve been pretty preoccupied with thoughts about the semantic web and how to utilize the possibilities of it recently. My problems with the various protocols, XML formats and microformats have been the lack of consuming services. In other words; it has been relatively painless to construct websites in a semantic way using microformats etc. but no cool services or applications have utilized it. In that regard it has felt much like just an idea with no real purpose. So I have been challenging my self to come up with ideas to utilize the semantic web – a way to consume some of this data in a way that makes sense. One of the formats I have been paying attention to is APML (Attention Profiling Markup Language).
