For opera devotees, fans, ‘tragics’ … etc., but mainly for myself, I’ve developed a synthetic RSS feed of news about Season events, tickets and subscriptions for Opera houses around the world that you can find near the bottom of this page.
I’ve used Yahoo Pipes and Yahoo’s YQL—an SQL-type query language for Yahoo search databases—to search for new season announcements from the world’s opera houses and mangled the results into an RSS format. The links in the feed jump to the announcement pages for each Opera house.
Hope you enjoy it. Please let me know.
