#701, extensible protocol support now available.

[Dagmar Timler]

Hi

A big thank you to Brent for implementing a new extensible protocol which enables us to communicate with 3rd party software.

See https://trac.openxdata.org/ticket/701

This has been merged into the trunk with revisions r6044 and r6043

He has also implemented an ODK version of the protocol, and a sample REST application. See tickets 

https://trac.openxdata.org/ticket/758

https://trac.openxdata.org/ticket/757

The next step is applying the ODK patch, once it has been verified (in the next iteration), and then implementing a comprehensive REST protocol.

I am in the process of writing and updating the documentation, but see the attached diagrams for a start. Please send feedback/comments!

Thanks

Dagmar

Hi Dagmar and Brent,

This is fantastic. Integration with ODK-Collect will really enrich the OXD platform and give us an additional client.

Hi Dagmar,

I would like to ask you a question. I can see a filter on the diagram. With this approach, is the MultiProtoSubmitFilter intercept an incoming Request, perform an authentication, load a proper protocol-API, and  pass the Request to MultiProtoHttpServletRequest?

Best,

Samson

Hi Samson

Thanks for the reply, and the question.

Yes, the MultiProtoSubmitFilter intercepts an incoming Request, performs authentication, loads the proper protocol-API (using the ProtocolLoader and ProtocolResolver), and `wraps` the Request `in a` MultiProtoHttpServletRequest, 

...

which is used by the MultiProtoSubmission to execute the ProtocolHandler request. Note: ProtocolResolver and ProtocolHandler are interfaces that must be implemented by each protocol-provider.

I hope this helps

Dagmar

That's all I need.

Thanks.
