Ivan, thanks for the link. This helps a lot. It is difficult for outsiders to keep track of the progress at W3C, which is why I opened this thread. The Turtle language and therefore also the Turtle in HTML <script> will be part of RDF 1.1, right? I am asking, because we might make use of this in NIF[1] in the following both ways. (Note that RDFa might also be an option or alternative). Both options (especially B) are drafts, so feedback is welcome. *****OPTION A (using hash - ids)***** <html> <head> <script> @base <...#> @prefix str: <http://nlp2rdf.lod2.eu/schema/string/> . @prefix itsx: <http://www.w3.org/20XX/XX/its2.0/> . <hash_10_6_03925a352b25cb24e02e1dae623d0936_Berlin> itsx:mentions <http://dbpedia.org/resource/Berlin> ; itsx:entityType <http://nerd.eurecom.fr/ontology#City> . </script> <body> Berlin is the capital of Germany. </body> *****OPTION B (using id milestones)***** <html> <head> <script> @base <...#> @prefix str: <http://nlp2rdf.lod2.eu/schema/string/> . @prefix itsx: <http://www.w3.org/20XX/XX/its2.0/> . <id_Berlin_uuid_3488jdndu438> itsx:mentions <http://dbpedia.org/resource/Berlin> ; itsx:entityType <http://nerd.eurecom.fr/ontology#City> . </script> <body> <span id="id_Berlin_uuid_3488jdndu438">Berlin<span> is the capital of Germany. </body> All the best, Sebastian [1] http://svn.aksw.org/papers/2012/WWW_NIF/public/string_ontology.pdf On 06/12/2012 06:40 PM, Ivan Herman wrote: > Sebastian, > > Stéphane Corlosquet has already commented on this, but somehow the thread went on: the upcoming Turtle standard refers to the possibility of adding Turtle into an HTML file using the<script> element[1].
