Hi Juan:
Two more suggestions:
1. For GoodRelations RDFa snippets, there are two tools
http://www.ebusiness-unibw.org/tools/grsnippetgen/
http://www.ebusiness-unibw.org/tools/goodrelations-annotator/en/
The help author RDFa for GoodRelations and vCard.
2. In general, I recommend (and use) the following approach to author
RDFa:
a) Model the data in Turtle syntax.
b) Convert the Turtle code into RDF/XML via any standard tool, e.g.
http://www.rdfabout.com/demo/validator/
c) Convert the RDF/XML into RDFa using
http://www.ebusiness-unibw.org/tools/rdf2rdfa/
d) If needed, integrate the visible content with the resulting snippet.
For me, this approach has increased productivity and reduced the
amount of bugs significantly, as soon as the data models are more
complex than just a few property-value pairs.
Best
Martin
