PuSH Feed Type
The people who run a DiscoverEd instance may wish to be updated nearly-immediately when there are new resources published by a curator.
Right now, DiscoverEd instances aggregate feeds and crawl every once in a while, often manually at the behest of the search engine operator. PubSubHubBub provides a way for the DiscoverEd instance to subscribe feeds and receive automatic, nearly-instantaneous notification of new information in the feed.
This can be built on top of existing Atom/RSS feeds that curators already publish.
This feature was defined and developed during the fun DC meeting thing. (Nathan, did that meeting have a name?)
To be considered working, this specification would provide the following things.
- Instructions for any Atom/RSS feed to participate in the PuSH network.
- DiscoverEd can accept POST requests from a PuSH hub. These POST requests are how the hub notifies the Nutch
- DiscoverEd can subscribe to updates from a PuSH hub (whose address can be configured in the configuration file).
