Great! and Compliments.

Simple authoring of  RDFa can be a problem. In a WYSIWYG way, or
precisely WYSIWYM with last M stands for Meaning... first mistake is
on steps required to produce it:

a. first add ontology/schema and its namespace
b. second add statements (great, but you must know how the information
may be structured - not really simple)

for simple use with WYSIWYG this is more complete but also complex.

Another approach, but limited to implementation to complex statements
structures sounds like an integration of RDFa on foaf-o-matic and
similar tools.

Third approach can be good is FOAFr by Michael, but the RDF source may
be exist. Then, but from manual editing, Dan Brickley said, about an
How-to (I think  Primer examples and working templates may be a right
way and also a page on our wiki).

So in a mixed approach think a WYSIWYG editor with "insert RDFa" menu
so now you have "Templates" (a mix from FOAFr with no RDF source and
working-examples) with ready code and a form to fill and have RDFa
output (like foaf-o-matic).

Well, the question is... if I need for a more complex RDFa Template to
fill in or direct code-writing? another menu item from menu can be
"Create Templates/Templates editor". In this way an author can
create/edit templates using first step to add onto, schema and more...
and then add semantic stuff to templates.

I think adding this middle (template editor but with more Templates
already done) step a WYSIWYG can able all people to use in a simple
way RDFa.

This is another interesting point. Implementing RDFa in real world can
be the solution also to sintatic sugar and more... thanks for this
implementation again.
