Hi Guys,
I have been playing a bit with ARC's erdf extractor, trying to
enhance the erdf specification with a very nice feature: bnodes! One
of the great things about erdf is the compatibility with any decent
html editor: just provide a set of css classes to make these xhtml
documents mean more, rdf-wise. Although the current specification
makes it possible to assign simple properties to the current
document, it does not have the power to bundle predicates with the
help of a blank node.
In order to keep the css semantics as easy as possible, I have
extended the way erdf handles the classnames with a postfix. By
adding an underscore to the classname, a blank node is generated for
the object value. The properties that are found inside this element
have this blank node as their subject.
This makes it very easy to create a foaf person:
<ul class="foaf-person_">
<li><p class="foaf-firstName">First Name</p></li>
<li><p class="foaf-firstName">Last Name</p></li>
</ul>
The erdf extractor already works. What do you think of this?
Regards, Robert
