Buran (meaning “Snowstorm” or “Blizzard”) was the first spaceplane to be produced as part of the Soviet/Russian Buran programme. Wikipedia
Buran
Buran is a library designed to consume and produce any RSS/Atom feeds using a data-driven approach. It works as a ROME wrapper, but in Buran, feeds are represented as data structures.
Buran can be used as an aggregator for various feed formats, converting them into regular Clojure data structures. When consuming a feed, Buran creates a map, which can be read or manipulated using regular functions such as filter, sort, assoc, dissoc, and more. After the modifications, Buran can generate your own feed, for example, in a different format (RSS 2.0, 1.0, 0.9x or Atom 1.0, 0.3).
