The New York Times has announced that it has made available RDF documents for us to use. They use 30,000 tags to power their Times Topics Pages and they intend to make them all available. They’ve also created a Google groups community for people to give feedback and share their experience with the data.
The Linked Data initiative is worth mentioning, it is busy with creating a huge repository of RDF data. They say “Linked Data is about using the Web to connect related data that wasn’t previously linked, or using the Web to lower the barriers to linking data currently linked using other methods.” They have a huge amount of resources there, including tools and learning resources as well.
TimBL spoke at the semantic web conference recently and said that the semantic web vision he had was a way off but that all data posted on the web should be in RDF format and also (from the CGN article):
“Few Web site managers are trained in RDF, and not many Web development applications use the standard, Berners-Lee admitted. “I’m not sure we have a grasp of our needs for the next phase of products,” he said. He implored the semantic Web community in the audience to educate and inspire their peers. The people they need to talk to, he said, “are not going to be found in these corridors,” referring to the conference attendees themselves.”
