1.  Introduction

1. Introduction

   This document describes a lightweight service for checking the
   availability of domain names.  This service is based on the IRIS
   framework and uses the data model defined by RFC 3982 [7].  By doing
   this, the domain availability service has the advantages provided by
   IRIS and DREG, such as well-known methods for server navigation,
   structured queries and results, and layered extensibility.

This document describes a lightweight service for checking the availability of domain names. This service is based on the IRIS framework and uses the data model defined by RFC 3982 [7]. By doing this, the domain availability service has the advantages provided by IRIS and DREG, such as well-known methods for server navigation, structured queries and results, and layered extensibility.

   The use of IRIS for this service also allows seamless integration
   between the domain availability service and the service provided by
   DREG.  This allows a user to find the availability status of a domain
   and reference the full registration information in DREG.

The use of IRIS for this service also allows seamless integration between the domain availability service and the service provided by DREG. This allows a user to find the availability status of a domain and reference the full registration information in DREG.

   The data model in this service (called a registry schema in IRIS
   terms) is a strict subset of the DREG data model.  This enables
   implementors to directly reuse DREG code paths and allows operators
   to deploy the service in either the same server processes as a DREG
   service (same host and port) or in a different server process
   (different port) or machine (different host).

The data model in this service (called a registry schema in IRIS terms) is a strict subset of the DREG data model. This enables implementors to directly reuse DREG code paths and allows operators to deploy the service in either the same server processes as a DREG service (same host and port) or in a different server process (different port) or machine (different host).

   As an example, an operator may wish to deploy both types of service
   on the same set of machines.  As time goes on, the operator may then
   decide to segregate the services, placing the domain availability
   service on one set of machines and the DREG service on a separate set
   of machines with a stricter set of controls.  Either deployment
   scenario is transparent to the end user and always appears to be
   seamlessly complementary.

   When coupled with [9], this domain availability service is
   lightweight and extremely efficient for high-volume, public-facing
   service.

3.1.  Schema Description

3.1. Schema Description

   References to XML elements with no namespace qualifier are from the
   schema defined in Section 3.2.  References to elements and attributes
   with the "iris" XML namespace qualifier are from the schema defined
   in IRIS [6].

References to XML elements with no namespace qualifier are from the schema defined in Section 3.2. References to elements and attributes with the "iris" XML namespace qualifier are from the schema defined in IRIS [6].

   The schema present in this document is tied to the protocol version
   associated with the XML namespace URI defined in Section 5.2.
   Extensions to the present DCHK schema are allowed, though not
   recommended, but would require a new version.  Please refer to RFC
   3981 [6] for more details about versioning the IRIS protocol.

   the scope of the formal XML syntax.  While reading this section,
   please reference Section 3.2 for needed details on the formal XML
   syntax.

3.3. Blocks Extensible Exchange Protocol (BEEP) Transport Compliance

   All DCHK clients and servers MUST implement the Lightweight UDP
   Transport Protocol (IRIS-LWZ) [9].  The use of other transports like
   the XML Pipelining with Chunks (IRIS-XPC) transport [12] or the BEEP
   transport [8] is optional and completely at the discretion of the
   server operator.  The XPC transport is in any case preferable to the
   BEEP transport.

4.  Internationalization Considerations

4. 国際化問題

   Implementors should be aware of considerations for
   internationalization in IRIS [6].

国際化において、作成者はIRIS[6]で問題を意識しているべきです。

   Clients needing to localize the data tags in this protocol should
   take note that localization is only needed on the names of XML
   elements and attributes, with the exception of elements containing
   date and time information.  The schema for this registry has been
   designed so that clients need not interpret the content of elements
   or attributes for localization, other than those elements containing
   date and time information.

このプロトコルでデータがタグであるとローカライズする必要があるクライアントはローカライズがXML要素と属性の名前で必要であるだけであるというノートを取るべきです、日時の情報を含む要素を除いて。 この登録への図式はクライアントがローカライズのために要素か属性の内容を解釈する必要はないように、設計されています、日時の情報を含むそれらの要素を除いて。

   Clients should also make use of the <language> elements provided in
   many of the results.  Results containing internationalized data can
   be accompanied by these elements in order to aid better localization
   of the data by the user.

また、クライアントは結果の多くに提供された<言語>要素を利用するべきです。 ユーザによるデータの、より良いローカライズを支援するためにこれらの要素で国際化しているデータを含む結果に伴うことができます。

   All date and time elements make use of the XML Schema [10] data type
   "dateTime".  If their contents are Coordinated Universal Time (UTC)
   timestamps, they MUST be specified by using the capitalized 'Z'
   indicator (instead of 'z').

すべての日時の要素が"dateTime"というXML Schema[10]データ型を利用します。 それらの内容が協定世界時(UTC)のタイムスタンプであるなら、大文字で書かれた'Z'インディケータ('z'の代わりに)を使用することによって、それらを指定しなければなりません。
