I am pleased to announce that I finally put online a new version of the crawler (1.2) that crawls RDF documents for Ping the Semantic Web. Now the web service is able to detect and index RDF files serialized in N3/Turtle. It means that much more RDF documents will be visible via Ping the Semantic Web since many RDF documents are serialized using N3 (and I think that more and more RDF documents will be serialized that way in the future).

Also, I entirely re-wrote the crawler. It is now (supposed to be) much more tolerant to the different way people could write their RDF documents. It is also much faster.

I also changed the exporting file format for the version 1.2. I changed the “topic” attribute for a “serialization” attribute. Why did I removed the topic attribute? Because it will be replaced by something else in the next month or so. The new “serialization” attribute can have one of these two values: “xml” or “n3”. It explicit the serialization format the crawler should expect by crawling this document.

In the mean time, if you find any documents that are not processed well by Ping the Semantic Web please leave a message in my mail box with the URL to that document so that I’ll be able to debug what is wrong.
