You can use existing standards to achieve these goals, as is already demonstrated. Fundamentally, you can use RDF Language to describe anything for machine processing, and of course that includes feeds, and the nature of said feeds (formats, deltas, refresh schedules etc..). Standards and technology aren't the problem here, so let's not frame matters that way, for broad clarity. -- Regards, Kingsley Idehen Founder & CEO OpenLink Software Company Web: http://www.openlinksw.com Personal Weblog 1: http://kidehen.blogspot.com Personal Weblog 2: http://www.openlinksw.com/blog/~kidehen Twitter Profile: https://twitter.com/kidehen Google+ Profile: https://plus.google.com/+KingsleyIdehen/about LinkedIn Profile: http://www.linkedin.com/in/kidehen Personal WebID: http://kingsley.idehen.net/dataspace/person/kidehen#this
