Once I can think of is cppcms::json

Also it should be updated to C++11 and probably do some small features updates. it is one of the fastest JSON parsers around (and yes it is way faster and convenient than one in property tree)

What do you think?

If the Boost community wants a JSON library, then I would like to suggest another, more versatile ibrary: https://github.com/breese/trial.protocol Documentation can be found here: http://breese.github.io/trial/protocol/ This library consists of two (well, three) parts: 1. A dynamic variable which is a variant type that can contain fundamental types, arrays, and associative arrays. This can be used as a parse tree for JSON and similar binary formats like MsgPack, UBJSON, BinToken, and CBOR. But it can also be used as a data container for, say, configuration data. The dynamic variable has iterators so it works with std algorithms. It also comes with a visitor. 2. A JSON parser/generator framework. This contains an incremental pull parser (json::reader) as the basic building-block. The incremental parser is used by a Boost.Serialization archive to enable serialization directly between JSON and C++ data structures. The incremental parser is also used by a tree parser that converts JSON into the before-mentioned dynamic variable. 3. A BinToken parser/generator framework. Like the JSON framework, but for the binary BinToken format. Currently undocumented.
