I have basic beginning to a parser for the BSON spec: http://www.mongodb.org/display/DOCS/BSON It is basically a binary compressed form of JSON. The usage model should be general, but I intend to read this data over TCP. [...] I was wondering if there is a tool set that exists for this purpose. For instance, should I use Data.Binary and make my Binary instance of get and put use the BSON protocol? Or is that not correct?
It sounds like this would work well. I just used Data.Binary for the first time yesterday to parse a few several-hundred-megabyte files, and I have no complaints. Its interface allows for testing of nice properties, like that (decode . encode $ x) == x. Along with quickCheck and an Arbitrary instance for your unserialised types, this makes it easy to find problems in your coding. The Data.Binary authors have also gone to some trouble to make it all efficient -- you really should try it out. Denis
