Information technology -- Open systems interconnection -- Part 1: Object identifier resolution system
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
ISO/IEC 29168-1:2011 specifies the object identifier (OID) resolution system (ORS), including the overall architecture and a DNS-based resolution mechanism.
It specifies the means for inserting any application-defined information associated with an OID node into the domain name system (DNS) and the means of retrieval of that information using the ORS.
It does not restrict the number of applications it can support.
It specifies the required operation of an ORS client, including the mapping of an OID-IRI (internationalized resource identifier) value by the ORS client into a DNS name to produce a DNS query for the specified application information and the processing of any returned information. The ORS has no role in the allocation or registration of OID nodes.
The required behaviour of an ORS client is specified, but the interfaces to it are specified only in terms of the semantics of the interaction. A bit-level application program interface is platform- and software-dependent, and is not in the scope of ISO/IEC 29168-1:2011.
It does not include a tutorial or complete specification on the management of DNS zone files; it specifies (only) the DNS resource records that need to be inserted in the zone files in order to support ORS access to the information associated with an OID node.
ISO/IEC 29168-1:2011 specifies required DNS zone file resource records, and prohibits the use of other resource records of a similar form but with different semantics (in DNS zone files in the .oid res.org domain). It does not otherwise restrict the general use of DNS zone files.
