Hi Sebastian, all,
coming back to an old thread.

Above is now updated to do better white space handling. There is now 
also a stylesheet to go back from NIF to an HTML document and generate 
its-ta-ident-ref etc.
How to use this
1) Sample input doc
http://www.w3.org/People/fsasaki/its20-general-processor/sample/nif-conversion/inputfile-without-ta-annotations.html
2) Output of generating NIF from 1), and of generating entity 
annotations in the NIF wrapper (here done manually)
http://www.w3.org/People/fsasaki/its20-general-processor/sample/nif-conversion/its-ta-2-nif-output.rdf
3) XSLT Stylesheet to go back from 2) to 1) and to add the entity 
annotations to the HTML
http://www.w3.org/People/fsasaki/its20-general-processor/tools/nif-2-its-ta.xsl
4) Output of 3)
http://www.w3.org/People/fsasaki/its20-general-processor/sample/nif-conversion/nit-2-its-ta-output.html
with some javascript to show the annotations.
Comments welcome. At Sebastian: the NIF RDF/XML is not yet up to date 
wrt to the comments you gave during the MWL-LT f2f call 8 May, I'll do 
that later.
