The only way to get a representative sample is to select some of the data randomly. ESW links a human-curated selection of sites, PTSW gets fed similarly similarly and Sindice crawled, IIUC. I don't think anyone even has a good idea of how many FOAF files are out there, to know if they have a good selection or not. I think we have 12 million or so unique ones, but we know there's an awful lot more out there. Ontop of that, "FOAF" is especially vague, eg. do qdos.com profiles (eg. http://qdos.com/user/Steve-Harris/18b6f60b41e05aaa418565ebfe901d6b/turtle) count as FOAF profiles? They have foaf:People in them, and use one or two foaf properties, but foaf: is not the most common prefix. What about DOAP files with lots of FOAF in them? Some use foaf: more than doap:, and so on. - Steve
