Secondary use cases

iSHARE Trust Framework's three primary use cases are supported by seven secondary use cases. These include:

• Processes related to registration;

• Processes that recur in primary use cases.

Processes related to registration

These four secondary use cases need to be completed before any, or specific, primary use cases can be initiated.

Any party needs to:

1a. Register adherence/certification in the iSHARE registry(satellite) via a Satellite (role) or Satellite Administrator

and later needs to be able to:

1b. Modify adherence/certification in the iSHARE registry(satellite) via a Satellite (role) or Satellite Administrator

Before initiating Human to Machine use cases, the Service Consumer needs to:

2a. Create Service Consumer and/or Human Service Consumer identity at Identity Provider Prerequisites:

• An agreement needs to be in place between Service Consumer and Identity Provider;

• An agreement needs to be in place between Service Provider and Identity Provider.

later, a Service Consumer needs to be able to:

2b. Modify Service Consumer and/or Human Service Consumer identity at Identity Provider

When delegating rights, the Entitled Party needs to:

3a. Register delegation at Service Provider, Entitled Party, or Authorization Registry Prerequisite:

• For registration at Service Provider or Authorization Registry, an agreement needs to be in place between Entitled Party and Service Provider or Authorization Registry.

later, an Entitled Party needs to be able to:

3b. Modify delegation at Service Provider, Entitled Party, or Authorization Registry

When authorizing something or -one, the Service Consumer needs to:

4a. Register authorization at Service Provider, Entitled Party, or Authorization Registry Prerequisite:

• For registration at Service Provider or Authorization Registry, an agreement needs to be in place between Service Consumer and Service Provider or Authorization Registry.

later, a Service Consumer needs to be able to:

4b. Modify authorization at Service Provider, Entitled Party, or Authorization Registry

Processes that recur in primary use cases

These three secondary use cases form the wiring of all primary use cases. Without them, primary use cases cannot be completed successfully.

In any primary use case, any party needs to:

5a. Check whether its counterparty is iSHARE adherent/certified (with the Satellite)

5b. Check whether its counterparty’s certificate is valid

In any primary use case, the Service Provider also needs to:

6. Determine an authorization decision based on entitlement-, delegation-, and/or authorization info in its own contract administration and/or from external PIPs

When delegation- or authorization info is requested by a Service Provider, an Authorization Registry or Entitled Party also needs to:

7. Determine authorization decision based on Service Consumer assertion included in Service Provider’s request

Please note that the secondary use cases will not be detailed more than the above. No depictions or sequence diagrams are to be developed (contrary to for the primary use cases). This (deliberately) leaves freedom in implementation.
