信息技术.开放系统互连.第1部分:对象标识符解析系统

[中文适用范围]： 本建议书/国际标准规定了对象标识符（OID）解析系统，包括整体架构和基于 DNS 的解析机制。它规定了将任何应用程序定义的与 OID 节点关联的信息插入 DNS 的方法（见第 6 条），以及使用 ORS 检索该信息的方法（见第 7 条）。它不限制其支持的应用程序数量。它规定了 ORS 客户端的必需操作（见第 7 条），包括由 ORS 客户端将 OID-IRI 值映射为 DNS 名称以生成针对指定应用程序信息的 DNS 查询，以及处理任何返回的信息。ORS 不参与 OID 节点的分配或注册。ORS 客户端的必需行为已规定，但其接口仅按交互的语义规定。位级应用程序接口取决于平台和软件，不在本建议书/国际标准的范围内。它不包括关于 DNS 区域文件管理的教程或完整规范（为此，请参阅 IETF RFC 1035 和 IETF RFC 3403）；它仅指定（仅）需要插入区域文件中以支持对与 OID 节点关联的信息的 ORS 访问的 DNS 资源记录（见 6.3）。本建议书/国际标准规定了必需的 DNS 区域文件资源记录，并禁止在（.oid-res.org 域中的 DNS 区域文件）中使用具有不同语义的类似形式的其他资源记录（见 6.2）。它不限制 DNS 区域文件的一般使用。 [外文原描述]： 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.
