This section describes how compliant is Bondy's WAMP implementation.


Bondy tries to be as compliant as possible with the WAMP Specification. However, because the specification was not designed from the ground up to consider a distributed router there are some requirements we cannot (and/or we do not want to) be compliant with.

The following two sections go into a detail compliance analysis listing what WAMP features Bondy implement and those cases in which Bondy does not comply with the Specification. In those particular cases you will also find an explanation of the rationale and the roadmap behind them.
