Long story short, PubSub.com is willing to offer a $5,000 bounty to whoever builds the "best" implementation of RFC3229 (Delta encoding in HTTP) with appropriate extensions for use with syndication feeds as an open source Apache module by Jan 1, 2005. The requirements for feed-oriented delta transfers are very, very close to those for passing around potentially huge, dynamically changing RDF/XML files, effectively synchronizing models between systems. Seems to me PubSub's solution could feed two birds with one bean, hence this mail. In the past few days there have been a couple of related developments - MSDN got stung with excessive bandwidth costs trying to broadcast the aggregated content of 1300+ feeds [2], and a (relatively!) simple algorithm for a delta-based solution has been described [3]. Most of the discussion has been taking place on the atom-syntax list [4]. Bob Wyman (of PubSub) describes the feed-oriented requirements some more at [5], there's a little more background on my blog at [6],[7]. Cheers, Danny.
