trias_to_ojp_2.0

Draft of XSLT (and server associcated) to do a trias -> ojp 2.0 transform, which allows clients to use trias and to connect in the background to an OJP 2.0 service. Currently only a draft for some request parts. PoC

Supported functionality

If something is missing that you need, then we need to extend the xslt.

XSLT 1.0

The core are two xslt:

• One transforms trias requests into ojp 2.0 requests: 'trias_to_ojp2.0_request.xslt'
• One transforms ojp 2.0 responses to trias responses: 'trias_to_ojp2.0_response.xlst'

Currently, a first draft of the first xslt is really done

We use mostly subtemplates for common elements and "functions".

Programs

• server.py: the service
• test_client.py: a simple test client
• test_transform_req.py: the test program for the the requests TRIAS -> OJP 2.0
• test_transform_resp.py: the test program for a Stop Event Response OJP 2.0 -> TRIAS

All are currently in a PoC state.

TODO

• Requests: Placeref better
• Responses: Do some of the other services

Adminstrative stuff
