I recently committed (as discussed with Pete) some code to org.jboss.seam.rss that enables you to use JSF tags for creating rss/atom feeds. It is based around the YARFRAW (http://yarfraw.sourceforge.net/) library. The only other new dependency is commons-lang. There is a quick-and-dirty build.xml included in the source dir that requires some modification, I didn't want to mess with the main build structure while it was in the "collecting feedback" stage. Any use for it in the trunk? Any considerations/feedback before expanding on it? It is currently very simplified, using a parent-child Feed -> Entries structure with several simplifications (only one author, name only etc). usage is in the lines of <r:feed xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:r="http://jboss.com/products/seam/rss" title="#{rss.feed.title}" uid="#{rss.feed.uid}" subtitle="#{rss.feed.subtitle}" updated="#{rss.feed.updated}" link="#{rss.feed.link}"> <ui:repeat value="#{rss.feed.entries}" var="entry"> <r:entry uid="#{entry.uid}" title="#{entry.title}" link="#{entry.link}" author="#{entry.author}" summary="#{entry.summary}" published="#{entry.published}" updated="#{entry.updated}" /> </ui:repeat> </r:feed> Some questions that came to mind: * Delivery mechanism: I currently use the document store. Any better alternatives? Some sort of flush + response complete? * Most attributes support both text and html formats. Should there be 1. One "textFormat"-swith at feed level 2. titleFormat and title, subtitleFormat and subtitle etc.. 3. Complex tag structure with <r:title format="html">title</r:title> etc? I'm currently leaning towards 1. * What level of the atom specs to support? All of it? At least r:link, r:author, r:contributor, r:category, r:source, r:generator would be required (or whatever multi-attribute 0:n stuff are nested in the feed/entry elements in the specs) * Any usage for it in wiki? I haven't really looked that much as the wiki, it seems to have an own feed servlet and perhaps some cacheing requirements --- Nik
