Detailed Description

An object ID is an OSI structure used to identify objects in an OSI environment. An

object ID might identify an application or a set of rules that both parties involved in

the communication recognize.

The following text describes enhancements to the APS procedures, the SPI interface,

and the PTrace tool that raise OSI/AS object ID limitations.

The OSI standards describe an object ID as an ordered set of integers used for

authoritative identification. No limit is placed on the size or number of integers. For

example, FTAM uses a default ap-title containing an object ID of {1,3,9999,1,7}.

Another example is the object ID for QUIPU, a directory service implementation,

which is {0,9,2342,19200300,99}. Lacking formal agreements in this area, OSI/AS

defined the object ID structure, ZAPS-DDL-OBJ-ID, to contain a set of up to sixteen

integers ranging from 0 to 32767.

OSI/AS now defines an expanded object ID structure, ZAPS-DDL-OBJ-ID-32, as

containing a set of up to 24 doubleword integers ranging from 0 to 2,147,483,647.

Object IDs are embedded in a number of OSI/AS structures. In order to fit expanded

object IDs into these structures, a mechanism is introduced by which an expanded

object ID can be compressed into the size of the regular object ID structure.

A regular object ID is an object ID described by the ZAPS-DDL-OBJ-ID structure.

An expanded object ID is an object ID described by the ZAPS-DDL-OBJ-ID-32

structure.

A compressed object ID is an object ID previously described by the ZAPS-DDL-

OBJ-ID or ZAPS-DDL-OBJ-ID-32 structure that has been compressed to fit into the

ZAPS-DDL-OBJ-ID structure.
