Hi Manu, thanks for this, good questions. Let me take a stab at it....

Hi Mark, Just to understand when certain triples are generated, it is my understanding that all of the examples below should not generate any triples, please verify: ----------------------------------------------------------------- <div resource="#me" rel="foaf:knows"> <span resource="#ben"> </div> -----------------------------------------------------------------
In all models <> foaf:knows <#me> .is generated if there is an implicit @about="" on the <body> element. But I am not sure that is the case, in which case that triple is not generated either (sorry Ben, we seem to disagree on that).
I first believed that in the model of Mark the <#me> foaf:knows <#ben> .is also generated regardless of whether the previous triple is generated. I then had to re-read the syntax document to find out, via the processing steps, that this is not so. (@rel has a higher priority in setting [new subject], ie, it will be set to null, and that is not send down to <span>)
Which by itself is also significant (thanks, Manu!): if there is an uncertainty on this for us, too, this shows the extra complexity induced by the usage of @resource (sorry Mark:-)...
----------------------------------------------------------------- <div href="#me" rel="foaf:knows"> <span href="#ben"> </div> -----------------------------------------------------------------
The behaviour should be _exactly_ like the one above.
----------------------------------------------------------------- <div href="#me"> <span rel="foaf:knows" href="#ben"> </div> -----------------------------------------------------------------
In the model of Mark @href sets the [new subject] in <div>, which is then turned into [current subject] that is sent down to <span>. Ie, the
<#me> foaf:knows <#ben> . will be generated.
-----------------------------------------------------------------
<div resource="#me" rel="foaf:knows">
<div resource="#ben">
<a rel="foaf:knows" href="#mark">Mark</a>
</div>
</div>

<#me> foaf:knows <#ben> . will be generated for the same reason. -- Ivan Herman, W3C Semantic Web Activity Lead Home: http://www.w3.org/People/Ivan/ PGP Key: http://www.ivan-herman.net/pgpkey.html FOAF: http://www.ivan-herman.net/foaf.rdf
