10、O 2012 All rights reservedForeword 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

11、in a subject for which a technical 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 Commi

12、ssion (IEC) on all matters 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 technica

13、l committees are circulated 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 shal

ISO 26324 was prepared by Technical Committee ISO/TC 46, Information and documentation, Subcommittee SC 9, Identification and description.

15、l object identifier DOI1) system provides an infrastructure for persistent unique identification of objects of any type. DOI is an acronym for “digital object identifier”, meaning a “digital identifier of an object” rather than an “identifier of a digital object”. In this International Standard, the

16、 term “digital object identifier” refers to the system defined in this International Standard unless otherwise stated. The DOI system was initiated by the International DOI Foundation in 1998, and initially developed with the collaboration of some participants in ISO/TC 46/SC 9. Due to its applicati

17、on in the fields of information and documentation and previous collaboration with some ISO/TC 46/SC 9 participants, it was introduced as a possible work item in 2004 and further developed from 2006 to 2010. The DOI system is designed to work over the Internet. A DOI name is permanently assigned to a

18、n object to provide a resolvable persistent network link to current information about that object, including where the object, or information about it, can be found on the Internet. While information about an object can change over time, its DOI name will not change. A DOI name can be resolved withi

19、n the DOI system to values of one or more types of data relating to the object identified by that DOI name, such as a URL, an e-mail address, other identifiers and descriptive metadata. The DOI system enables the construction of automated services and transactions. Applications of the DOI system inc

20、lude but are not limited to managing information and documentation location and access; managing metadata; facilitating electronic transactions; persistent unique identification of any form of any data; and commercial and non-commercial transactions. The content of an object associated with a DOI na

21、me is described unambiguously by DOI metadata, based on a structured extensible data model that enables the object to be associated with metadata of any desired degree of precision and granularity to support description and services. The data model supports interoperability between DOI applications.

22、 The scope of the DOI system is not defined by reference to the type of content (format, etc.) of the referent, but by reference to the functionalities it provides and the context of use. The DOI system provides, within networks of DOI applications, for unique identification, persistence, resolution

23、, metadata and semantic interoperability. _ 1) DOI is a registered trademark.

24、RD ISO 26324:2012(E) ISO 2012 All rights reserved 1Information and documentation Digital object identifier system 1 Scope This International Standard specifies the syntax, description and resolution functional components of the digital object identifier system, and the general principles for the cre

25、ation, registration and administration of DOI names (where DOI is an acronym for “digital object identifier”). This International Standard defines the syntax for a DOI name, which is used for the identification of an object of any material form (digital or physical) or an abstraction (such as a text

26、ual work) where there is a functional need to distinguish it from other objects. The DOI name does not replace, nor is it an alternative for, an identifier used in another scheme, such as the schemes defined by ISO/TC 46/SC 9. This International Standard describes how the DOI system can be used in c

27、onjunction with another identifier scheme (for example, to provide additional functionality, such as resolution, where this is not already available), and how the character string of that other scheme can be integrated into the DOI system through the DOI metadata record and/or the DOI syntax. This I

28、nternational Standard does not specify specific technologies to implement the syntax, description and resolution functional components of the digital object identifier system. 2 Normative references The following referenced document is indispensable for the application of this document.

33、e object (3.9) within the DOI system (3.6) NOTE 1 Names consist of characters in a sequence specified by the DOI syntax (3.5). NOTE 2 The terms “identifier” and “number” are sometimes but not always used in the same sense and are to be avoided where ambiguity can arise. The unqualified use of “DOI”

34、alone can also be ambiguous. Therefore “DOI” is always used in conjunction with a specific noun e.g. DOI name (3.4), DOI system (3.6) unless the meaning is sufficiently clear from an earlier mention or the specific context. 3.5 DOI syntax rules for the form and sequence of characters comprising any

44、.1 General characteristics The DOI syntax shall be made up of a DOI prefix and a DOI suffix separated by a forward slash. There is no defined limit on the length of the DOI name, or of the DOI prefix or DOI suffix. The DOI name is case-insensitive and can incorporate any printable characters from th

45、e legal graphic characters of Unicode. Further constraints on character use (e.g. use of language-specific alphanumeric characters) can be defined for an application by the ISO 26324 Registration Authority. The combination of a unique DOI prefix (assigned to a particular DOI registrant) and a unique

46、 DOI suffix (provided by that registrant for a specific object) is unique, and so allows the de-centralized allocation of DOI names. The DOI name is an opaque string for the purposes of the DOI system. No definitive information may be inferred from the specific character string of a DOI name. In par

47、ticular, the inclusion in a DOI name of any registrant code allocated to a specific registrant does not provide evidence of the ownership of rights or current management responsibility of any intellectual property in the referent. Such information may be asserted in the associated metadata. BS ISO 2
