No indeed, perhaps these and their answers belong in the FAQ. > I'm having another play with my blog data in Longwell which seems like > it's approaching the comfort limit : 267102 triples, 32MB RDF/XML > (upping options to -Xms128M -Xmx512M).

For that, we rely on Sesame; in their efforts to move towards a final 2.0 release, they haven't quite made it to adding in DB support. There are remnants of Sesame 1 in our code, when it was possible to use a database backing store, but I'm pretty sure those fragments are dead. A bit from Sesame folks on the present state regarding MySQL: http://www.openrdf.org/forum/mvnforum/viewthread?thread=1143 > I'd like to see what serendipity there may be in making some of the > big data sets available alongside this : WordNet, Cyc, Wikipedia3... > Is this feasible right now? You're going to run into scalability problems at some point, probably soon. If you're up for it, I'd like to know at what size you find things stop working reasonably (and a bit about your hardware). > I'm also noodling with Jena & Redland stores on the same server, I was > wondering whether there was any neat way of exposing their contents > (which may be big) to Longwell?

You can do it from the command line, but not while it's running. Consider SemBank for non-static datasets. There was a fellow on the list who suggested he used Sesame contexts to aid in updating his data, but I don't think we saw code for that scenario. -- Ryan Lee [EMAIL PROTECTED] MIT CSAIL Research Staff +1.617.253.5327 http://simile.mit.edu/ _______________________________________________ General mailing list [email protected] http://simile.mit.edu/mailman/listinfo/general
