13、SO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, gov

14、ernmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC

15、 Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the membe

16、r bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical expe

17、rts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is

18、 approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is revie

19、wed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying a

20、ny or all such patent rights. ISO/TS 18876-1 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and integration, Subcommittee SC 4, Industrial data. This International Standard is organized as a series of parts, each published separately. The structure of this Internationa

21、l Standard is described in this part of ISO 18876.

TECHNICAL SPECIFICATION ISO/TS 18876-1:2003(E) ISO 2003 All rights reserved 1 Industrial automation systems and integration Integration of industrial data for exchange, access and sharing Part 1: Architecture overview and description 1 Scope This Technical Sp

27、ecification establishes an architecture, a methodology, and other specifications for integrating industrial data for exchange, access, and sharing. The following activities are supported: integrating data which may be: from different sources or different contexts, described by different models, or d

28、efined in different modelling languages; sharing data among applications through systems integration architectures; resolving conflict between models developed with different objectives; translating data between different encodings; translating models between different modelling languages. The follo

29、wing are within the scope of ISO 18876: integration models; methods for creating, extending, and updating integration models; methods for creating a mapping specification to map data instances between an integration model and an application model that falls within its scope; encoding and decoding of

30、 data and models with different formats, such as SGML 1, XML 7, EXPRESS 3, UML 6 and ISO 10303-21 4; methods for consolidating data sets from different sources and different models; modelling and mapping specification languages. The following is within the scope of this part of ISO 18876: the archit

31、ecture and an outline of the methodology. The following are outside the scope of this part of ISO 18876: integration models; ISO/TS 18876-1:2003(E) 2 ISO 2003 All rights reserved detailed specifications of the methodology; NOTE Such specifications can be found in other parts of ISO 18876 or in other

34、 abbreviations apply; those taken from ISO 10303-1 are repeated below for convenience. NOTE 1 Definitions copied verbatim from other standards are followed by a reference to the standard in brackets, such as “ISO 10303-1”. In these cases the definition in the referenced document is normative; its re

35、petition here is informative and in the case of any discrepancy the definition in the referenced document has precedence. An explanatory note follows definitions that have been adapted from other standards. In these cases, the definition given here is normative for the pur- poses of this part of ISO

36、 18876. 3.1.1 application model (AM) model that represents information used for some particular purpose NOTE Some application models are also integration models (see 3.1.12). 3.1.2 class category or division of things 1)To be published. (Revision of ISO/IEC 8824-1:1998) The following referenced docu

37、ments are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO/TS 18876-1:2003(E) ISO 2003 All rights reserved 3 NOTE There are a number

38、of ways that class can be defined. This definition is intended to be as broad as possible, and is broader than that used in ISO 15926-2. EXAMPLE Pump, power station, engineer, and fictional space vehicle are examples of classes. 3.1.3 concept general notion or idea of something 3.1.4 data representa

39、tion of information in a formal manner suitable for communication, interpretation, or processing by human beings or computers ISO 10303-1 3.1.5 data model set of constructs that provides the definition, structure, and format of data, whether physical or abstract in the sense of being bound to some r

40、ecording medium 3.1.6 derived concept concept in an integration model that is wholly defined in terms of primitive concepts 3.1.7 encoding transformation transformation of the way data elements are represented for computer processing EXAMPLE Conversion of data governed by an EXPRESS schema from an I

41、SO 10303-21 file to an XML document is an example of an encoding transformation. 3.1.8 foundation concept primitive concept that determines the underlying world viewpoint of an integration model NOTE There can be a number of integration models. Each will have its own modelling paradigm which is char

42、acterised by the foundation concepts that it contains. EXAMPLE The concepts of class and individual are foundation concepts for a general integration model. 3.1.9 general concept primitive concept that has very wide applicability, but is a specialization of some foundation concept NOTE A concept may

43、 be considered to be a foundation concept by one community, while it is considered to be a gen- eral concept by another. 3.1.10 individual thing that exists in space and time NOTE This includes things that actually exist, or have existed, and things that possibly exist (past, present, and future) in

44、 space and time. EXAMPLE The pump with serial number ABC123, Battersea Power Station, Sir Joseph Whitworth, and the Starship “Enterprise” are examples of individuals. ISO/TS 18876-1:2003(E) 4 ISO 2003 All rights reserved 3.1.11 information facts, concepts, or instructions ISO 10303-1 3.1.12 integrat

45、ion activity that creates, modifies, or extends an integration model 3.1.13 integration model (IM) application model that can represent the information that is represented by two or more application models NOTE Being an integration model is about the role one model plays with respect to one or more

46、application models. 3.1.14 mapping correspondence between instances of one model and instances of another model that represent the same mean- ing NOTE A mapping can be uni-directional or bi-directional. 3.1.15 mapping specification definition of the transformations necessary to take information acco

47、rding to one data model and represent the same information according to another data model NOTE 1 A mapping specification can include data structure transformations, data value transformations, data encoding transformations, and terminology transformations. NOTE 2 Mapping specifications can be proce

48、dural, or declarative, or a combination of these. 3.1.16 model limited information representation of something suitable for some purpose 3.1.17 model context sum of implicit concepts and constraints that limit the possible extension of a model without changing any exist- ing declarations NOTE 1 The

49、model context is therefore the class of all possible extensions to a model. NOTE 2 This term is more general than application context as defined in ISO 10303-1. 3.1.18 model scope range of information that an application model can describe 3.1.19 primitive concept concept in an integration model that is not wholly defined in terms of other concepts 3.1.20 specific concept primitive concept that is a speci
