Preface/Scope

Scope

1.1 General
The Directory Standards define not only the protocol but also the behaviour of DSAs when they collaborate to carry out the purpose of the Directory. In order to achieve consistency and full interoperability, it is necessary to select from the options and interpretations laid down in the Directory Standards, and in particular within [ISO/IEC 9594-4 / CCITT X.518].

This part of ISO/IEC ISP 10615 specifies the behaviour of DSAs in exercising the DAP, the DSP, or both, that is required to carry out Distributed Operations in accordance with these requirements.

The scope of this part of ISO/IEC ISP 10615 is to define:

- Static capabilities that are required by DSAs in order to achieve acceptable levels of service in cooperation with other DSAs
- Procedures, based on procedures given within the base standards, in the detail required to achieve consistency and interoperability
- Protocol use, as required to implement the procedures.

It is applicable to DSAs implementing the '88 Directory Standards [ISO/IEC 9594:1990 / CCITT X.500:1988].

It applies to all DSAs that contain a component of the distributed Directory, although many of its requirements are inapplicable to DSAs that do not support the invocation of DSP operations.

Implementations claiming conformance to this part of ISO/IEC ISP 10615 may be based on either ISO/IEC 9594 or CCITT X.500 or both. There are no practical differences as far as this part of ISO/IEC ISP 10615 is concerned.

This part of ISO/IEC ISP 10615 is not free-standing. Compliance with this part of ISO/IEC ISP 10615 requires compliance with ISO/IEC ISP 10615 parts 2 to 4 inclusive, and with normative references identified in those documents. Conversely, this part of the part of ISO/IEC ISP 10615 is applicable to DSAs which conform to other parts of ISO/IEC ISP 10615, and in particular to parts 2 (ADI12), 3 (ADI21) and 4 (ADI22).

1.2 Position within the taxonomy
This part of ISO/IEC ISP 10615 is identified in ISO/IEC TR 10000-2 as ADI32 Directory - Distributed Operations -
DSA Support of Distributed Operations.

1.3 Scenario
In the Distributed Directory, one mode of interaction is the chaining (including multicasting) of enquiries in accordance with the procedures laid down in [ISO/IEC 9594-4 / CCITT X.518]. Another is the following of referrals and of embedded cont inuation references.

In carrying out these procedures, a DSA is accessed by a DUA or another DSA, and carries out the requested action with or without ref erence to other DSAs. This part of ISO/IEC ISP 10615 is concerned with the information contained in a DSA to enable it to determine that other DSAs are involved, and with the procedures whereby other DSAs can be involved, by the use of chaining or referrals (Figure 1).
