My, can't we admit that XPath is a bit over our head, so we prefer confronting the admin we're supposed to be cooperating with? Wrt resources, my guess it's about par traffic-wise (1-5k per book vs. megabytes of RDF) but much better CPU-wise. That is, if you don't want the RDF for other fine things like metadata etc.
I think you've missed my point. The RDF flat-out cannot tell me which of the target _formats_ are available for immediate download to the users. I'm not looking for which _titles_ are available in the catalog, I'm looking for which _formats_ are available. Also note that I'm already parsing the feeds to see what the top 'n' titles are already, so parsing XML via whatever methods I need is not the blocker here. Let me give you an example of two titles available in the catalog: Vergänglichkeit by Sigmund Freud http://www.gutenberg.org/cache/plucker/29514/29514 The Lost Word by Henry Van Dyke http://www.gutenberg.org/cache/plucker/4384/4384 Both of these _titles_ are available in the Gutenberg catalog, but the second one is not available in the Plucker _format_ for immediate download. Big difference from parsing title availability from the catalog.rdf file. Make sense now?
