rdf AND rdf-a?

Morning all

The site I'm working on uses microformats fairly heavily. And we've encountered all the usual problems: accessibility, lack of namespacing / scope etc. Anyway for accessibility reasons we've just updated our standards to prohibit the use of the microformat abbreviation design pattern (so most interesting microformats). This may change when we do a little more testing but there's no date for that so it's looking like microformats are bye-bye

Pretty soon (honest) we'll be putting RDF views of the data live

So my questions are:

- if we have full RDF, should we also be using rdf-a?

- if so what would be the benefits (yahoo search stuff?)?

- and what would be the costs (ham-fisted html hackers wrecking the templates springs to mind ;) )?

any pointers much appreciated
