The permitted act is accessing the resource, which may involve the user downloading the resource, or the provider delivering the resource. It is assumed that use events are always preceded by an access so that an appropriate agreement is also required in that case. In other cases the agreement may be implicit with a transaction being initiated when an access event takes place. An attempt to access a resource without making first making a request, and thereby creating an agreement, may trigger a request, with the access only continuing once the request has been completed. Payment could be handled in various ways, users may pay directly with a credit card, their institution may be charged, or they may pay money into the broker with the broker making payments to the service providers.
Provider offers terms and conditions under which resource can be accessed.
User selects and accepts appropriate terms and conditions and an agreement is recorded. The payment mechanism is also agreed upon at this point. Provider requests payment for access to resource. Payment is made by the user, or by the broker on the user's behalf. User accesses resource.
