Abstract

Systems, methods, and apparatus, including computer program products, providing unique identifiers for data-bearing digital objects. Scheme-based definition of uniqueness contexts and scheme-based mappings between identifiers are described. A method of one aspect includes generating a first object identifier for a first object of a first object type on a first system, the first object identifier having an identification context. The identification context includes a first system identifier or one or more second object identifiers of one or more respective second objects. The method further includes providing the first object identifier with the identification context to identify the first object uniquely. A method of another aspect includes defining an equivalence mapping between first identifiers with respective first identification context values and second identifiers with respective second identification context values; and using the equivalence mapping to map an identifier for one object to an identifier for another semantically equivalent object.

Dependent claims

A system comprising:

a computer having memory, the memory storing instructions that when executed by the computer perform operations comprising:
defining an aggregate object on a data processing system, wherein the aggregate object incorporating data from at least two aggregating objects, and each of the aggregating objects has a respective object identifier, and wherein the aggregate object includes a scheme name and scheme ID;
generating an object identifier for the aggregate object, the object identifier for the aggregate object being unique within a particular identification context, wherein the identification context includes a structural identification context that identifies particular dependencies of the aggregate object, the object identifier for the aggregate object being unique with respect to the particular dependencies and including a concatenation of at least one of the object identifiers of the at least two aggregating objects, and at least one of the particular dependencies is based on the incorporated aggregating object data, wherein the identification context further includes at least one of the object identifiers of the aggregating objects, wherein the generation of the object identifier for the aggregate object is based at least in part on a structural identification scheme specifying that aggregating objects belong to the structural identification context and further specifying how object identifiers of the aggregating objects are concatenated into the object identifier for the aggregate object;
and
providing the object identifier of the aggregate object together with the corresponding identification context to identify the aggregate object uniquely on the data processing system.

A computer-implemented method comprising the following steps performed by at least one processor:

defining an aggregate object on a data processing system, wherein the aggregate object incorporating data from at least two aggregating objects, and each of the aggregating objects has a respective object identifier, and wherein the aggregate object includes a scheme name and scheme ID;
generating an object identifier for the aggregate object, the object identifier for the aggregate object being unique within a particular identification context, wherein the identification context includes a structural identification context that identifies particular dependencies of the aggregate object, the object identifier for the aggregate object being unique with respect to the particular dependencies and including a concatenation of at least one of the object identifiers of the at least two aggregating objects, and at least one of the particular dependencies is based on the incorporated aggregating object data, wherein the identification context further includes at least one of the object identifiers of the aggregating objects, wherein the generation of the object identifier for the aggregate object is based at least in part on a structural identification scheme specifying that aggregating objects belong to the structural identification context and further specifying how object identifiers of the aggregating objects are concatenated into the object identifier for the aggregate object;
and
providing the object identifier of the aggregate object together with the corresponding identification context to identify the aggregate object on the data processing system.

A computer program product, encoded on a non-transitory, computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

defining an aggregate object, wherein the aggregate object incorporates data from at least two aggregating objects, each of the aggregating objects having a respective object identifier, and wherein the aggregate object includes a scheme name and scheme ID;
generating an object identifier for the aggregate object, the object identifier for the aggregate object being unique within a particular identification context, wherein the identification context includes a structural identification context that identifies particular dependencies of the aggregate object, the object identifier for the aggregate object being unique with respect to the particular dependencies and including a concatenation of at least one of the object identifiers of the at least two aggregating objects, and at least one of the particular dependencies based on the incorporated aggregating object data, wherein the identification context further includes at least one of the object identifiers of the aggregating objects, wherein the generation of the object identifier for the aggregate object is based at least in part on a structural identification scheme specifying that aggregating objects belong to the structural identification context and further specifying how object identifiers of the aggregating objects are concatenated into the object identifier for the aggregate object;
and
providing the object identifier of the aggregate object together with the corresponding identification context to identify the aggregate object uniquely.
