Hello RDFa WG members,
This is a comment on Profiles in the latest RDFa WD [1]. The draft
<div about="#person">
<dt>Job title</dt>
<dd class="job" property="jobtitle"></dd>
</div>
After RDFa parsing, the following RDF triple is generated from this
snippet (assuming a term mapping for jobtitle):
<#person> ex:jobtitle "" .
I ask that the parsing algorithm be changed so that no triple is
generated in the case where an element has a @property attribute, no
@content attribute, and no text content.
The motivation for this change: Template-generated HTML often contains
empty elements like in the example above. This happens when a field is
not present in a given record. Generating an empty <td/> or <span/> is
often less effort than suppressing the generation of the element
altogether, so thats' what template authors often do. When a zero-
length element carrying @property is encountered, then it's almost
certain that the author's intention was *not* to generate a zero-
length literal, so the parsing algorithm should reflect that.
Best,
Richard
