8、SERVICE Summary This Recommendation I International Standard describes how the ODP Trading Function can be realised using information entries and support mechanisms of the OS1 Directory. This Specification is to be used in conjunction with the ODP Trading Function Standard (see ITU-T Rec. X.950 I IS

9、O/IEC 13235-1). If there are any discrepancies between the prescriptive statements in ITU-T Rec. X.950 and those in this Specification, the prescriptive statements in ITU-T Rec. X.950 take precedence. The scope of this Specification is: - - - standardised templates for Trading Function information o

10、bjects in the DIT; descriptions of mapping of Trading Function operations to appropriate Directory operations; description of use of other Directory features to provide the support mechanisms for implementing the ODP Trading Function. The field of application of this Specification is for the constru

11、ction of the ODP Trading Function using the OS1 Directory, when required. Source The ITU-T Recommendation X.952 was approved on the 12th of December 1997.

The IT Telecommunication Standardization Sector (ITU-T) is a permanent organ of the IT. The ITU-T is responsible for studying technical, operating a

13、nd tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn,

14、produce Recommendations on these topics. The approval of Recommendations by the Members of the IT-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis

15、with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of

16、 this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of

17、the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged

X.952 (1997 E) STD*ITU-T RECMN X.752-ENGL 3777 4862571 0648336 304 Introduction The ODP Trading Function (see ITU-T Rec. X.950-Senes I ISO/IEC 13235) provides the means to offer a service and the means to discover services

29、that have been offered. ITU-T Rec. X.950 I ISOiEC 13235-1 defines an enterprise Specification, an information Specification and a computational Specification of this Trading Function. No engineering Specification is defined in ITU-T Rec. X.950 I ISODEC 13235-1. This Recommendation I International St

30、andard describes how the Specifications of the Trading Function in ITU-T Rec. X.950 I ISOIEC 13235-1 can be engineered using OS1 Directory Service (see IT-T Rec. X.500 I ISODEC 9594-1) to store information and to provide support mechanisms. This Specification does not prescribe that a trader must be

31、 engineered by using OS1 Directory. But if OS1 Directory is used, this Specification defines standardised templates for information entries (e.g. service offer and link information objects) in the Directory DIT. Clause 5 gives an overview of how the Trading Function is implemented as a combination o

32、f X.500 DUA and DSA. The X.500 DSA is used to store the Trader Information Object and a Trader DUA (T-DUA) implements the functionality required by a Trader, which is difficult, or impossible, to implement using OS1 Directory services. Clause 6 defines the standardised templates for information entr

33、ies of the Trader Information Object, the information known to a particular Trader. Clause 7 describes mapping of Trading Function operations to appropriate Directory operations. Clause 8 specifies a minimal Type Repository Function necessary to enable the correct functioning of the X.500 Directory

34、for Trading. Clause 9 describes the mechanisms used to enable the handling of dynamic properties of a Traders service offers. This Specification contains two annexes. Annex A is a normative schema definition of Trader definitions. Annex B is an informative schema definition of a sample service descr

The scope of this Specification is: Scope and field of application - - - standardised templates for Trading Function

38、 information objects in the DIT; descriptions of mapping of Trading Function operations to appropriate Directory operations; description of use of other Directory features to provide the support mechanisms for implementing the ODP Trading Function. This Specification does not prescribe that a trader

39、 must be engineered by using OS1 Directory. But if OS1 Directory is used, this Specification defines standardised templates for information entries (e.g. service offer and link information objects) in the Directory DIT. This Specification does not put any restrictions on where these entries are plac

40、ed in the Directory DIT. That is, this Specification does not standardise any structure rules. This Specification does describe a mechanism to provide the Trading Function using OS1 Directory. The field of application of this Specification is for the construction of the ODP Trading Function using th

41、e OS1 Directory, when required. 2 Normative References The following Recommendations and International Standards contain provisions which, through reference in this text, constitute provisions of this Recommendation I International Standard.
