I've been thinking about this sort of data syndication problem for the past few months, and have sketched out some simple ideas at http://www.java.utoronto.ca/news/. As Henryk alludes to (at least I think he means this), there are several separable layers to consider in an application design: a) mechanism for requesting or 'pushing' objects/data (e.g. XML-RPC, SOAP, whatever) b) transport (e.g., HTTP, SMTP, IIOP) c) encoding for the data being sent (e.g. MIME, XML, other) I've mostly been thinking about (c) and an XML-mechanism for encoding syndicated data. In principle, such a message could contain either the data or a URL reference that, when dereferenced, 'pulls' the data back. But, regardless of the approach taken, I think it's important to separate the three layers noted above, as in the long run this will make it easier for you (or anyone else) to expand the application's scope at each layer, without affecting the others. There are many others looking at generic syndication issues also, and some quite large/rich XML specifications on this topic (e.g., OCS, RSS). I have a list of references at: http://www.java.utoronto.ca/news/references.html that points to most of them.
