Atomisator, a framework to build custom RSS feeds

We are all overwhelmed by the amount of data in our feed readers. While this problem is unavoidable if you keep on adding new feeds in it, they could be automatically filtered and categorized to reduce the flow of data.

I wanted for a long time to try out some custom filters over my feeds to find for example related entries, by trying to understand the meaning of the posts, using tools like NLTK.

So I needed a playground for this, where I could play with feeds.

I think the closest tool for this is to use Yahoo Pipes but as far as I know, the only way to create custom filters is to run a web service and call it from Yahoo Pipes.

Anyways, I started to code a framework (at first it was an example for my latest book) that looks a lot like Yahoo Pipes in its principles. I don't have any User Interface at this time of course, but a simple plugin-based tool that will let me combine my code snippets with feeds.

It is called Atomisator (see http://atomisator.ziade.org).

The process is quite simple:
1. Readers are plugins that know how to read a source and provide entries out of it. 2. Filters are plugins that know how to remove unwanted entries, or enhance them (change their title, summary, etc.). They can be combined. 3. the entries are then pushed in a database. This is useful to avoid doublons, and to keep track of past entries. 4. to create the feed, the entries are read from the database 5. Enhancers are plugins that will add to entries extra info. Typically info that can't be stored, like Digg comments if the entry is detected on Digg, or Google related searches, and so on 6. The feed is then generated.

Right now I am focusing on making it fast, which is not simple because the plugins can play with all entries in the database.

It is in early stage and undertested, but it kinda works. I pushed it at PyPI to see of it meets interest. If it does, I will document the process of writing plugins.

Make sure you have SQlite installed, and give it a try :
$ easy_install atomisator.main

$ atomisator -c atomisator.cfg

$ atomisator

You will have an atomisator.xml feed created. You can add other feeds in atomisator.cfg as well and try them.

Now with this environment, I can start to try out custom algorithms over my feeds.

I've been told the name doesn't sound right in Ehglish, but it does in French so I keep it ;)
