The work of preparing Inte

10、rnational 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, governmental and non-governmental, in liaison wi

11、th 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 Directives, Part 2.The main task of technical

12、 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 member bodies casting a vote.Attention is drawn to t

13、he possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 17369 was prepared by Technical Committee ISO/TC 154, Processes, data elements and documents in commerce, industry and ad

14、ministration.This first edition of ISO 17369 cancels and replaces ISO/TS 17369:2005, which has been technically revised.iv ISO 2013 All rights reservedBS ISO 17369:2013ISO 17369:2013(E)IntroductionThe Statistical Data and Metadata Exchange (SDMX) initiative (http:/www.sdmx.org) sets standards that c

15、an facilitate the exchange of statistical data and metadata using modern information technology, with an emphasis on aggregated data.There are several sections to the SDMX technical specification.a) The SDMX Framework Document presents the scope and integrated functionality of the concepts and speci

16、fications that constitute the SDMX standard.b) The SDMX Information Model is the information model upon which syntax-specific implementations described in the other sections are based. This is intended for technicians wishing to understand the complete scope of the technical standards in a syntax-ne

17、utral form. It includes as an annex a tutorial on UML (Unified Modelling Language).c) SDMX-ML is the XML format for the exchange of SDMX-structured data and metadata. This document describes the use of the XML syntax in SDMX messages, and is accompanied by a set of XML schemas and sample XML documen

18、t instances.d) SDMX-EDI is the UN/EDIFACT format for exchange of SDMX-structured data and metadata. This describes the use of the UN/EDIFACT syntax in SDMX messages.e) The SDMX Registry Specification provides for a central registry of information about available data and reference metadata, and for

19、a repository containing structural metadata and provisioning information. This specification defines the basic services offered by the SDMX registry: registration of data and metadata; querying for data and metadata; and subscription/notification regarding updates to the registry.f) The SDMX Technic

20、al Notes constitute a guide to help those who wish to use the SDMX specifications. They include notes on the expressive differences of the various messages and syntaxes; versioning; maintenance agencies; the SDMX Registry.g) Web Services Guidelines constitute a guide for those who wish to implement

21、SDMX using web-services technologies. They place an emphasis on those aspects of web-services technologies (including, but not requiring, an SDMX-conformant registry) which will work regardless of the development environment or platform used to create the web service.SDMX version 2.0 represented a s

22、ignificant increase in scope, and also provided more complete support in those areas covered in SDMX version 1.0. SDMX version 2.0 is backward-compatible with SDMX version 1.0, so that existing implementations can be easily migrated to conformance with SDMX version 2.0.SDMX version 2.1 represents a

23、set of changes resulting from several years of implementation experience with SDMX version 2.0. The changes do not represent a major increase in scope or functionality, but do correct some bugs and add functionalities in some cases. Major changes in SDMX-ML include a much stronger alignment of the X

24、ML schemas with the information model, to emphasize inheritance and object-oriented features, and increased precision and flexibility in the attachment of metadata reports to specific objects in the SDMX information model.The idea of backward-compatibility in the standards is based on the informatio

25、n model. In both releases, some non-backward-compatible changes have been made to the SDMX-ML formats. However, the same set of information required to use SDMX version 1.0 will permit the use of the same features in SDMX version 2.0. Thus, a data structure definition (DSD) is easily translated from

26、 SDMX version 1.0 to SDMX version 2.0, without requiring any new information regarding structures, etc. There have been no changes to the SDMX-EDI format.The main changes from SDMX version 1.0 to SDMX version 2.0 can be briefly summarized as follows. Reference Metadata: In addition to describing and

27、 specifying data structures and formats (along with related structural metadata), SDMX version 2.0 also provides for the exchange of metadata which ISO 2013 All rights reserved vBS ISO 17369:2013ISO 17369:2013(E)is distinct from the structural metadata in SDMX version 1.0. This category includes “re

28、ference” metadata (regarding data quality, methodology and similar types: it can be configured by the user to include whatever concepts require reporting); metadata related to data provisioning (release calendar information, description of the data and metadata provided, etc.); and metadata relevant

29、 to the exchange of categorization schemes. SDMX Registry: Provision is made in SDMX version 2.0 for standard communication with registry services, to support a data-sharing model of statistical exchange. These services include registration of data and metadata, querying of registered data and metad

30、ata, and subscription/notification. Structural Metadata: The support for exchange of statistical data and related structural metadata has been expanded. Some support is provided for qualitative data; data cube structures are described; hierarchical code lists are supported; relationships between dat

31、a structures can be expressed, providing support for extensibility of data structures; and the description of functional dependencies within cubes are supported.The main changes from SDMX version 2.0 to SDMX version 2.1 can be briefly summarized as follows. Web-services-oriented changes: Several org

32、anizations have been implementing web services applications using SDMX, and these implementations have resulted in several changes to the specifications. Because the nature of SDMX web services could not be anticipated at the time of the original drafting of the specifications, the web services guid

33、elines have been completely re-developed. Presentational changes: Much work has gone into using various technologies for the visualization of SDMX data and metadata, and some changes have been proposed as a result, to better leverage this graphical visualization. Consistency issues: There have been

34、some areas where the draft specifications were inconsistent in minor ways, and these have been addressed. Clarifications in documentation: In some cases it has been identified that the documentation of specific fields within the standard needed clarification and elaboration, and these issues have be

35、en addressed. Optimization for XML technologies: Implementation has shown that it is possible to better organize the XML schemas for use within common technology development tools which work with XML. These changes are primarily focused on leveraging the object-oriented features of W3C XML Schema to

36、 allow for easier processing of SDMX data and metadata. Consistency between the SDMX-ML and the SDMX information model: Certain aspects of the XML schemas and UML model have been more closely aligned, to allow for easier comprehension of the SDMX model. Technical bugs: Some minor technical bugs have

37、 been identified. These bugs have been addressed. Support for non-time-series data in the generic format: One area which has been extended is the ability to express non-time-series data as part of the generic data message. Simplification of the data structure definition/specific message types: Both

38、time series (SDMX version 2.0 Compact) and non-time series data sets (SDMX version 2.0 cross sectional) use the same underlying structure for a structure-specific formatted message, which is specific to the data structure definition of the data set. Simplification and better support for the metadata

39、 structure: New use cases have been reported and these are now supported by a re-modelled metadata structure definition. Support for partial item schemes such as a code list: The concept of a partial (sub-set) item scheme such as a partial code list for use in exchange scenarios has been introduced.
