We just spotted an issue with the RDFa parser in ARC. It looks like it is prone to forget some triples if the document does not end with a \n.

The following gist shows the issue: https://gist.github.com/725644 - this gives 5 triples. However, 10 are embedded in the HTML document. Adding a \n at the end of that document gives 10 triples.

This behavior has been tested with the latest version of ARC.
