Hamsta currently lacks a standardized network interface that would allow other systems accessing its capabilities. There is a custom network interface with text-parsing based protocol that is poorly documented and needs to be implemented on the client side to be usable. This interface does not use any standardized way of communication or library.
This project suggests to add a standardized web service interface (let us call it API) to Hamsta. Expected attributes are following.
Current Zend Framework OpenID implementation does not support the protocol version 2.0 fully. For example the Yadis discovery is not supported at all. Thus the Zend Framework OpenID module can not be used with OpenID providers using this version of the protocol.
