WS-Agreement Interoperability

NOTES FROM TELECON.:

1. We need to be clear on what interoperability issues we are trying to demonstrate. The first step would be to demonstrate interoperability on the schema.

2. Identify interoperability on the type of agreement factory mechanism being used. For instance, whether it would be useful to demonstrate interoperability on synchronous vs. asynchronous agreement creation mechanisms.

3. Identify what aspect of interoperability would be needed on the protocol. How would this be verified with respect to the implementation.

INTRODUCTION

Scenario 1:

An Agreement Factory exists at Location A. This is sent a message from Location B. Location A generates an agreement template and inserts it into a repository at Location B. Location B is then able to make use of this agreement and invoke services based on it. (this should include a Use Case diagram or a Sequence Diagram)

Participants involved:

Use-cases:

• AssessGrid - VIOLA job submission/reservation
• SORMA as consumer of Agreements
• ASKALON
  • Alex Villazon (supervisor)
  • Mumtaz Siddiqui (implemented WS-Agreement for Askalon)

Test-cases: Here we should describe the test-cases we are going to consider for the interoperability test.

Results of text-cases:

INTEROP. DEMONSTRATION

This scenario demonstrates:

Scenario 1 - AgreementFactory Test Cases:

ServiceConsumer - ServiceProvider:

• consumer discovers endpoint of AgreementFactory
• consumer queries discovered AgreementFactory for templates
• consumer stores resolved templates as tupels {Factory EPR, template}*
• consumer selects one of the template
• consumer create AgreementOffer based on selected template
• consumer calls ~createAgreement message on AgreementFacotry via associated EPR
• provider creates new Agreement Service instance
• provider returns EPR to created Agreement Service instance
• consumer validates that Agreeement ServiceTerms are recognized correctly
