RDF datastore comparisons?

Hi,
Sorry for relatively broad question. Is there some form of comparison 
document that recaps the main RDF datastore technologies (Sesame, Jena, 
Boca, Virtuozo...) their main features and characteristics such as 
backend DB support, SPARQL end-point support, etc.
Thanks in advance
