Thanks for your reply I m planning to drop the last sentence of the paragraph I sent to you anyway We know for sure that Guha created the Meta Content Framework which was announced by 1997 but exactly who did what after that can t be determined from our current references The Netscape press release of March 1999 doesn t mention Guha s name so we can t even declare him as the author of that implementation The editors who created History of web syndication technology may be able to gather more data about this period
