Connector Restricted Usage Policy for multiple connectors

[jfernandezsqs]

I have deployed three DSC connectors (one acting as provider with a catalog, offer, representation, artifact, contract and two usage policies rules of Connector Restricted Usage) and the other connectors acting as consumers (connector_B and connector_C).

The rules applied are the Connector Restricted Usage ones (URL https://connector_B and URL https://connector_C):

{"@type":"ids:Permission","@id":"https://connectora:8080/api/rules/492eb8bd-4a66-4be5-bf50-e54228dc347b","ids:description":[{"@value":"Restricted usage only for connector_b","@type":"http://www.w3.org/2001/XMLSchema#string"}],"ids:constraint":[{"@type":"ids:Constraint","@id":"https://w3id.org/idsa/autogen/constraint/a5b50075-89d5-4940-90ac-9b35a397894b","ids:operator":{"@id":"https://w3id.org/idsa/code/SAME_AS"},"ids:leftOperand":{"@id":"https://w3id.org/idsa/code/SYSTEM"},"ids:rightOperand":{"@value":"https://connector_B","@type":"http://www.w3.org/2001/XMLSchema#anyURI"}}],"ids:action":[{"@id":"https://w3id.org/idsa/code/USE"}],"ids:title":[{"@value":"Restricted usage connector B","@type":"http://www.w3.org/2001/XMLSchema#string"}],"ids:target":"https://connectora:8080/api/artifacts/bf435743-df13-42fc-bf92-f9fecf45d1a9"}

When I try to stablish the negotiation contract POST /api/ids/contract

curl -X 'POST' \

It is obtained the following error:

Is it possible to stablish a contract agreement with an offer that has a contract containing multiple Connector Restricted Usage rules? This is allowing data access to more than one specific consumer connector using the Resticted Connector Usage policy.

Hi @jfernandezsqs
Unfortunately the DSC does not support multiple connectors to be whitelisted. See implementation here: https://github.com/International-Data-Spaces-Association/DataspaceConnector/blob/main/src/main/java/io/dataspaceconnector/service/usagecontrol/RuleValidator.java which assumes that each policy must be valid. Thus, for the moment no OR condition is applicable.
