Summary

Recommendation ITU-T X.672 | International Standard ISO/IEC 29168-1 specifies the object identifier (OID) resolution system (ORS). This enables (arbitrary) information to be associated with any ORS-supported OID node (of the international OID tree defined in Rec. ITU-T X.660 | ISO/IEC 9834-1). This associated information is identified by an application specification that may have a requirement for instances of that application (running on any computer system) to obtain the associated information by an ORS search, using an Abstract Syntax Notation One (ASN.1) OID‑internationalized resource identifier value to identify the node.

Currently defined application information for a node includes the canonical form of an international OID, child node information, registration information about the owner of the node, a reference to an ASN.1 module identified by the node, information supporting tag-based applications and information supporting cybersecurity.
