Blog zeitgeist tool TailRank is opening up its parsed feed update stream to third-party developers through a new feed delta API. Developers can request the latest 100 posts discovered and parsed by TailRank’s spiders.
The API is a good way to capture a snapshot of the most active and highly linked blogs written in English at any one time. Past research and development projects have seeded their data sets from Weblogs.com and perhaps TailRank can be a new source of information for newcomers to analyze the blogosphere in different ways. API keys will be available at no cost for non-profits and educational work and under license to commercial organizations.
TailRank lead developer Kevin Burton also maintains Apache’s Jakarta FeedParser project, a Java library that helps make sense out of the various feed formats and namespaces on the web today.
