10、Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO 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 t

11、echnical committee has been established has the right to be represented on that committee. International organizations, governmental 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

12、 of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulate

13、d to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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

14、for identifying any or all such patent rights. ISO 24619 was prepared by Technical Committee ISO/TC 37, Terminology and other language and content resources, Subcommittee SC 4, Language resource management. BS ISO 24619:2011ISO 24619:2011(E) ISO 2011 All rights reserved vIntroduction References and

15、citations are an important part of documents and papers. Traditionally authors use them to provide proper acknowledgment to the author(s) of other papers as a source for their work or use them to support their argumentation. Citations usually contain information that enables a reader to establish th

16、e possible relevance of the cited paper and to identify it unambiguously. Any librarian or knowledgeable person is able to retrieve the document using well-established procedures based on the information in the citation. The availability of directly accessible documents on the web has inspired the p

17、ractice of adding a web location (URI 4) to the citation information. This practice has made it possible to access referenced documents directly in web browsers as well as in other document viewers. This practice is already recommended in standards like ISO 690, although the emphasis there is more o

18、n identifying published resources and parts than on providing sustainable access to them. Increasingly often, such references need to be exploited by machines and software applications as well as by people, requiring reliable availability of the referenced resources. Problems with access that occur

19、when resources are relocated have led to the use of persistent identifier (PID) frameworks 23, 24. Current approaches 18, 19, 24address the resource relocation problem by introducing resolver services that translate a resource identifier to its actual current location. These resolver services have a

20、n added advantage of permitting the association of additional metadata with the identifier. Elaborate frameworks such as the Digital Object Identifier (DOI)14, use this feature to manage extra services, for instance copyright information. The practice of using persistent identifiers to cite and refe

21、rence scientific data, along with individual resources as well as data sets, is less well developed. It is no less powerful, however, in that it allows readers of a paper, or users of a knowledge resource, direct access to the primary scientific data to which the resource refers. When using referenc

22、es to access scientific data, including language resources, it becomes important to be able also to refer to and access parts of resources. This is especially true in the domain of language resources, where several layers of granularity are usually superimposed on the same data set or resource colle

23、ction. Therefore, discussions in this International Standard concerning the use and requirements for PID frameworks extensively explore how these frameworks can deal efficiently with identifying and accessing parts of resources. Special recommendations indicate how to approach the granularity issue

24、when issuing PIDs for resources and resource collections. The need to apply PID frameworks for identifying resources contained in scientific data sets has also increased since modern archives and repositories have begun to weave a network of related complex resources that may be distributed over sev

25、eral locations. In these cases, permanent linkage is a prerequisite. In a multimedia lexicon for instance, a lexical item can refer to images not necessarily physically in the lexicon, or that are even referenced at a different site under control of a different organization. However, the link betwee

26、n the lexicon item and the image must remain valid, even if some servers or files are subject to relocation over time. Emerging e-Science scenarios, which make use of distributed services processing distributed resources, are also completely dependent on having transparent access from any processing

27、 service, irrespective of where it is located or what organization may operate it. This implies that resolving resource references should not be hampered in any way by unnecessary dependencies involving reliance on unsustainable or unpredictable services, whether they are technical or organizational

28、. The requirement that services like PID frameworks be accessible to the whole community of language resource and technology providers is further complicated by the need to provide resolvable PIDs without imposing commercial dependencies on resource providers other than the fundamental and well-esta

29、blished requirements for maintaining resources on the Internet. BS ISO 24619:2011BS ISO 24619:2011INTERNATIONAL STANDARD ISO 24619:2011(E) ISO 2011 All rights reserved 1Language resource management Persistent identification and sustainable access (PISA) 1 Scope This International Standard specifies

30、requirements for the persistent identifier (PID) framework and for using PIDs as references and citations of language resources in documents as well as in language resources themselves. In this context, examples of language resources include such works as digital dictionaries, language-purposed term

31、inological resources, machine-translation lexica, annotated multimedia/multimodal corpora, text corpora that have been annotated with, for example, morpho-syntactic information, and the like. Computational and applied linguists and information specialists create such resources. This International St

32、andard also addresses issues of persistence and granularity of references to resources, first by requiring that persistent references be implemented by using a PID framework and further by imposing requirements on any PID frameworks used for this purpose. PID frameworks also allow the association of

33、 general metadata with the identifier, which can also contain citation information. This International Standard specifies minimum requirements for effective use of PIDs in language resources and cites the use of several possible existing standards and de-facto standards, such as: ISO 69016, APA3, ML

38、owing terms and definitions apply. 3.1 Resources 3.1.1 resource digital object on the web with a specific identity that can be addressed with a URI (3.2.2) NOTE 1 Adapted from IETF RFC 3986. NOTE 2 In the context of this International Standard, a resource can also be a language resource that has an

39、online representation. NOTE 3 A resource can have several representations. Depending on the PID framework (3.2.5), identification of a specific representation can be encoded in the identifier (ARK, see B.3) or be left to the content negotiating process 8 between the web client (3.3.8) that uses the

40、resolved PID to fetch the resource (3.1.1) and the resource server (3.3.6). 3.1.2 language resource digital resource that provides information about one or more languages NOTE Language resources cover lexicographical, terminological, morpho-syntactical, corpus-related, or semantic resources or digit

41、al resources used to study linguistic phenomena like texts and multimedia/multimodal recordings. They are created and used by linguists, information specialists, lexicographers and terminologists, among others. They frequently comprise many small records compiled within a larger work, and are often

42、authoritative in nature, such as standardized terminologies and glossaries issued by standards bodies such as ISO, IETF, W3C, etc. 3.1.3 complex resource resource (3.1.1) consisting of multiple constituent parts, each of which can be accessed individually NOTE A complex resource can be a federated r
