43、 define a set of services that may be used to facilitate the mapping of identifiable elements between communicating applications.Applications may have,and often do have,different identifications for the same objects.In any exchange all parties to the exchange must agree on the names or identifiers o

44、f the objects.Often this agreement is managed through a set of alias identification registration services.This standard defines an alias service model(ASM)and formal object model for translating context in information exchanges.This standard defines a simple implementation approach to a subset of th

45、e much broader issue that is addressed by ISO/IEC 11179 Information technology-Metadata registries(MOR)and ISO/IEC 19763 Information technology-Metamodel framework for interoperability(MFI).This standard enables the use of existing ontology mapping standards(e.g.,OWL/RDF.topic maps)as part of the co

46、ntextualization of objects in the exchange and new standards as they are developed as part of the predicate definition between items.This standard provides for the exchange of the semantic mapping information as well as format information.The specific grammar and mechanisms used to express the conte

47、xt in these standards is not part of the scope of this standard.All references to levels in this standard pertain to the levels of the function hierarchy model identified in the ISA-95 Part 1 standard.This standard defines a set of services definitions that are designed to provide the functionality

48、needed for a vendor independent method for translating identifiers across different names paces.Using a common representation of objects,such as enumeration strings,property names,and equipment tag names,is an important element of any integrated system.Enterprise/Control system integration involves

49、multiple different steps to exchange data between different computer system applications,as shown in Figure 1.a)The applications usually have different internal representations of exchanged objects in their own local data stores.In an exchange,this representation is converted from the local format t

50、o a commonly accepted global format.The ISA-95 Part 2 standard defines representations of a global format for Level 4-3 data exchanges.The Part 4 standard defines representations of a global format for Level 3-3 data exchanges.b)Any object identification and enumeration which needs to be exchanged a
