17、IntroductionThis International Standard is the culmination of more than a decade of standards development work by the International Committee for Documentation (CIDOC) of the International Council of Museums (ICOM). Work on this International Standard began in 1996 under the auspices of the ICOM-CID

18、OC Documentation Standards Working Group. The document1)provided by CIDOC formed the basis for ISO 21127 which was first published in 2006. While the initial impetus for the work came from the museum community, it has since spread to encompass other types of cultural heritage institution. This Inter

19、national Standard has been appropriated and extended to meet the needs of other institutions dealing with cultural heritage.The primary purpose of this International Standard is to offer a conceptual basis for the mediation of information between cultural heritage organizations such as museums, libr

20、aries, and archives. This International Standard aims to provide a common reference point against which divergent and incompatible sources of information can be compared and, ultimately, harmonized.ISO 21127 is an ontology2)1for cultural heritage information: a formal representation of the conceptua

21、l scheme, or “world view”, underlying the database applications and documentation systems that are used by cultural heritage institutions. It is important to note that this International Standard aims to clarify the logic of what cultural heritage institutions do in fact document; it is not intended

22、 as a normative specification of what they should document. The primary role of this International Standard is to enable information exchange and integration between heterogeneous sources of cultural heritage information. It aims to provide the semantic definitions and clarifications needed to trans

23、form disparate, localized information sources into a coherent global resource, be it within an institution, an intranet, or on the Internet.The specific aims of this International Standard are to serve as a common language for domain experts and IT developers when formulating requirements, serve as

24、a formal language for the identification of common information contents in different data formats; in particular to support the implementation of automatic data transformation algorithms from local to global data structures without loss of meaning. These transformation algorithms are useful for data

25、 exchange, data migration from legacy systems, data information integration, and mediation of heterogeneous sources, support associative queries against integrated resources by providing a global model of the basic classes and their associations to formulate such queries, and provide developers of i

26、nformation systems with a guide to good practice in conceptual modelling.The ISO 21127 ontology is expressed as a series of interrelated concepts with definitions. This presentation is similar to that used for a thesaurus. However, the ontology is not intended as a terminology standard and does not

27、set out to define the terms that are typically used as data in cultural heritage documentation. Although the presentation provided here is complete, it is an intentionally compact and concise presentation of the ontologys 86 classes and 137 unique properties. It does not attempt to articulate the in

28、heritance of properties by subclasses throughout the class hierarchy (this would require the declaration of several thousand properties, as opposed to 137). However, this definition does contain all the information needed to infer and automatically generate a full declaration of all properties, incl

29、uding inherited properties.1) The CIDOC CRM Special Interest Group continues to maintain a version of this original document, usually known as the “CIDOC Conceptual Reference Model” or CIDOC CRM.2) In the sense used in computer science, i.e. it describes in a formal language the relevant explicit an

30、d implicit concepts and the relationships between them. ISO 2014 All rights reserved vBS ISO 21127:2014BS ISO 21127:2014Information and documentation A reference ontology for the interchange of cultural heritage information1 ScopeThis International Standard establishes guidelines for the exchange of

31、 information between cultural heritage institutions. In simple terms, this can be defined as the information managed by museums, libraries, and archives.A more detailed definition can be articulated by defining both the intended scope, a broad and maximally inclusive definition of general principles

32、, and the practical scope, which is defined by reference to a set of specific museum documentation standards and practices.The intended scope of this International Standard is defined as the exchange and integration of heterogeneous scientific documentation relating to museum collections. This defin

33、ition requires further elaboration. The term “scientific documentation” is intended to convey the requirement that the depth and quality of descriptive information that can be handled by this International Standard need to be sufficient for serious academic research. This does not mean that informat

34、ion intended for presentation to members of the general public is excluded, but rather that this International Standard is intended to provide the level of detail and precision expected and required by museum professionals and researchers in the field. The term “museum collections” is intended to co

35、ver all types of material collected and displayed by museums and related institutions, as defined by ICOM3). This includes collections, sites, and monuments relating to fields such as social history, ethnography, archaeology, fine and applied arts, natural history, history of sciences and technology

36、. The documentation of collections includes the detailed description of individual items within collections, groups of items, and collections as a whole. This International Standard is specifically intended to cover contextual information (i.e. the historical, geographical, and theoretical backgroun

37、d that gives museum collections much of their cultural significance and value). The exchange of relevant information with libraries and archives, and harmonization with their models, falls within the intended scope of this International Standard. Information required solely for the administration an

38、d management of cultural institutions, such as information relating to personnel, accounting, and visitor statistics, falls outside the intended scope of this International Standard.The practical scope4)of this International Standard is the set of reference standards for museum documentation that ha

39、ve been used to guide and validate its development. This International Standard covers the same domain of discourse as the union of these reference documents; consequently, for any data that is correctly encoded in accordance with any of these reference documents, a form of encoding can be created t

40、hat is both compatible with the current standard and which entails no semantic loss.2 ConformanceUsers intending to take advantage of the semantic interoperability offered by this International Standard should ensure conformance with the relevant data structures. Conformance pertains either to data

Any encoding of data in a formal language that preserves the relations of the classes, properties, and inheritance rules defined by this International Standard, is r

43、egarded as conformant.Conformance with this International Standard does not require complete matching of all local documentation structures, nor that all concepts and structures present in this International Standard be implemented. This International Standard is intended to allow room both for exte

44、nsions, needed to capture the full richness of cultural information, and for simplification, in the interests of economy. A system will be deemed partially conformant if it supports a subset of subclasses and subproperties defined by this International Standard. Designers of the system should publis

45、h details of the constructs that are supported.The focus of this International Standard is the exchange and mediation of structured information. It does not require the interpretation of unstructured (free text) information into a structured, logical form. Unstructured information is supported, but

46、falls outside the scope of conformance considerations.Any documentation system will be deemed conformant with this International Standard, regardless of the internal data structures it uses; if a deterministic logical algorithm can be constructed, that transforms data contained in the system into a

47、directly compatible form without loss of meaning. No assumptions are made as to the nature of this algorithm. “Without loss of meaning” signifies that designers and users of the system are satisfied that the data representation corresponds to the semantic definitions provided by this International S

48、tandard.3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.3.1classcategory of items that share one or more common traitsNote 1 to entry: Class traits serve as criteria to identify items that belong to the class. These traits need not be explicitly fo

49、rmulated in logical terms, but can be described in a text (called a scope note) that refers to a common conceptualization of domain experts. The sum of these traits is called the intension of the class. A class can be the domain or range of none, one, or more properties formally defined in a model. The formally defined properties need not be part of the intension of their domains or ranges; such properties are optional. An item that belongs to a class is called an instance of this class. A class is associated with an open set of real-life insta
