Venus
Sam Ruby has been giving out plenty of examples from his version of the Planet software, called Venus.
Here are the posts so far: Reading Lists, Filters, MeMeme, Stream Editing.
For me, what this needs is to be hooked up to a real database. So the configuration, including the list of subscriptions, and the cache of feeds would be stored in some relational schema. The reason why I think this is important is that for me it opens the data to be used by many different apps without needing access to the filesystem. Sam gives a good example of using Ruby to re-use the data contained in the feed cache.
Once something like that is in place it could start moving towards being more of a feedreader than just an aggregator of feeds.
I think the coolest part about this is(as Joe Gregario pointed out, it transforms all of the data into Atom as part of the filtering process. It opens many possibilities, most of which I would bet haven’t even been conceived of yet.
And now I realise that tvrss is almost exactly the same as Planet, but for a specific source of data. Oh well, it’s character building.
