An algorithm for determining dependability information. An algorithm for some cryptographic operation. The cryptographic algorithm used. If there are more algorithms involved, this will be the next cryptographic algorithm. The abstract base for the dependability information data types. The date and time when this dependability information has been assigned. The algorithm used to determine the dependability information: - none = no algorithm, value guessed - internal = provider internal algorithm URI of the issuer of the dependability attribute. The ID of the attribute at the issuer site. All dependability information. Represents a service's availability. The numerical value of the availability attribute. Represents a service's reliability. The numerical value of the reliability attribute. Represents a service's safety. Represents a service's confidentiality. The algorithm(s) that are used while communicating with other services. The algorithm(s) used while processing data inside the service. The algorithm(s) used while storing data in the service's long term storage. Represents a service's integrity. Represents a service's maintainability.
