Жалпыға ортақ объектілерді идентификациялау коды (OID)

Globally unambiguous persistent name
In computing, object identifiers or OIDs are an identifier mechanism standardized by the International Telecommunication Union (ITU) and ISO/IEC for naming any object, concept, or "thing" with a globally unambiguous persistent name.

ISO/IEC 6523 "International Code Designator" uses OIDs with the prefix "1.3". In computer security, OIDs serve to name almost every object type in X.509 certificates, such as components of Distinguished Names, CPSs, etc. Within X.500 and LDAP schemas and protocols, OIDs uniquely name each attribute type and object class, and other elements of schema. In Simple Network Management Protocol (SNMP), each node in a management information base (MIB) is identified by an OID. IANA assigns Private Enterprise Numbers (PEN) to companies and other organizations under the 1.3.6.1.4.1 node. OIDs down tree from these are among the most commonly seen; for example, within SNMP MIBs, as LDAP attributes, and as vendor suboptions in the Dynamic Host Configuration Protocol (DHCP). In the United States, Health Level Seven (HL7), a standards developing organization in the area of electronic health care data exchange, is the assigning authority at the 2.16.840.1.113883 (joint iso itu t. country. us. organization. hl7) node. HL7 maintains its own OID registry, and as of December 1, 2020 it contained almost 20,000 nodes, most of them under the HL7 root. DICOM uses OIDs. The Centers for Disease Control and Prevention uses OIDs to manage the many complex values sets or "vocabularies" used in the Public Health Information Network (PHIN) Vocabulary Access and Distribution System (VADS).
