Re: [ros-users] Web introspection tools

There isn't a single format for binary JSON, there's BSON [1], UBJSON [2],
BJSON [3], ... However, there's no reason that serialized ROS messages
couldn't be used (we allow web service calls using this in ROStful), though
with DDS for ROS 2.0, maybe that format will be changing soon.
