Trackback implementation: rel="trackback" vs RDF

Question

Hi,

I want my Rails App to parse external websites for a trackback URL but I'm not really sure if I should just look for a

<a href="url" rel="trackback">Text</a>

or follow the RDF specifications described by sixapart. Or both. Wordpress and Techcrunch both only offer a rel="trackback" link and they should know. On the other hand maybe some blog only provides RDF and I'm missing the link.

What do you think?

And is there any ready gem/plugin out there (it's really hard to google for trackback...)

Thanks.

UPDATE

I'm now first trying to find the RDF information. If I do not find anything, I look for the link tag. I was refering to the sixapart specifications. Thanks for your help.

I'm checking for both now (first RDF, then link if not successfull). I was refering to the sixapart specifications. Thanks for your help!
