be used to describe SOAP 1.2 messages serialized as XML 1.0.

|

この文書は XML 1.0 で直列化した SOAP 1.2 メッセージを記述するために使用できる
|
| 31 |
[CODE(MIME)[application/soap+xml]] 媒体型を定義します。

* 1. Introduction
|
| 35 |
|
| 36 |
> SOAP version 1.2 (SOAP) is a lightweight protocol intended for
|
| 37 |
exchange of structured information between peers in a decentralized,
|
| 38 |
distributed environment. It defines an extensible messaging
|
| 39 |
framework that contains a message construct based on XML technologies
|
| 40 |
that can be exchanged over a variety of underlying protocols.
|
| 41 |
|
| 42 |
SOAP 1.2 版 (SOAP) は脱集中分散環境の同輩間の構造化情報の交換のための軽量プロトコルです。
|
| 43 |
SOAP は様々なプロトコルの上で交換できる XML
|
| 44 |
技術を基にしたメッセージ構造を含む、拡張可能なメッセージ付けの枠組みを定義しています。
|
| 45 |
|
| 46 |
> This specification defines the media type "application/soap+xml"
|
| 47 |
which can be used to identify SOAP 1.2 message envelopes that have
|
| 48 |
been serialized with XML 1.0. Such serializations are useful as the
|
| 49 |
basis of "wire formats" for SOAP 1.2 Protocol Binding Specifications
|
| 50 |
[W3C.REC-soap12-part1-20030624], or in other situations where an XML
|
| 51 |
serialization of a SOAP envelope is required.
|
| 52 |
|
| 53 |
この仕様書は XML 1.0 で直列化した SOAP 1.2 メッセージ封筒を識別するために使うことができる
|
| 54 |
[DFN[[CODE(MIME)[[[application/soap+xml]]]]]] 媒体型を定義します。
|
| 55 |
XML 1.0 直列化形は、 SOAP 1.2 プロトコル束縛仕様書の[Q[[RUBYB[通信] [wire]]形]]の基礎として、
|
| 56 |
あるいはその他 SOAP 封筒の XML 直列化が必要な状況で有用です。
|
| 57 |
|
| 58 |
> The "application/soap+xml" media type explicitly identifies SOAP 1.2
|
| 59 |
message envelopes that have been serialised with XML 1.0; message
|
| 60 |
envelopes with a different SOAP namespace version or using another
|
| 61 |
XML serialisation MUST NOT use it.
|
| 62 |
|
| 63 |
[CODE(MIME)[application/soap+xml]] 媒体型は明示的に SOAP 1.2
|
| 64 |
メッセージ封筒を XML 1.0 で直列化したものを識別します。
|
| 65 |
異なる SOAP 名前空間版や他の XML 直列化を使ったメッセージ封筒は、
|
| 66 |
この媒体型を使っては'''なりません'''。
|
| 67 |
|

> The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
|
| 69 |
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
|
| 70 |
document are to be interpreted as described in [RFC2119].

:MIME media type name:application
|
| 77 |
:MIME subtype name:soap+xml
|
| 78 |
:Required parameters:none
|
| 79 |
:Optional parameters:
|
| 80 |
|
| 81 |
>
|
| 82 |
:"charset":This parameter has identical semantics to the charset
|
| 83 |
parameter of the "application/xml" media type as specified in
|
| 84 |
RFC 3023 [RFC3023].
|
| 85 |
:"action":This optional parameter can be used to specify the URI
|
| 86 |
that identifies the intent of the message. In SOAP 1.2, it
|
| 87 |
serves a similar purpose as the SOAPAction HTTP header field
|
| 88 |
did in SOAP 1.1. Namely, its value identifies the intent of the message.
|
| 89 |
|
| 90 |
:[CODE(MIME)[[[charset]]]]:[[RFC 3023]] で規定されている
|
| 91 |
[CODE(MIME)[[[application/xml]]]] 媒体型の [CODE(MIME)[[[charset]]]]
|
| 92 |
引数と同じ意味を持つ引数です。
|
| 93 |
:[CODE(MIME)[[[action]]]]:メッセージの意図を識別する URI
|
| 94 |
を指定するために使うことができる省略可能な引数です。
|
| 95 |
SOAP 1.2 では SOAP 1.1 の [CODE(HTTP)[[[SOAPAction]]]] HTTP
|
| 96 |
頭欄と同様の目的で使います。つまり、値はメッセージの意図を識別します。
|
| 97 |
|
| 98 |
> The value of the action parameter is an absolute URI-reference
|
| 99 |
as defined by RFC 2396 [RFC2396], which MUST be non-empty.
|
| 100 |
SOAP places no restrictions on the specificity of the URI or
|
| 101 |
that it is resolvable. Although the purpose of the action
|
| 102 |
parameter is to indicate the intent of the SOAP message there
|
| 103 |
is no mechanism for automatically computing the value based on
|
| 104 |
the SOAP envelope. In other words, the value has to be
|
| 105 |
determined out of band. It is recommended that the same value
|
| 106 |
be used to identify sets of message types that are logically
|
| 107 |
connected in some manner, for example part of the same
|
| 108 |
"service". It is strongly RECOMMENDED that the URI be globally
|
| 109 |
unique and stable over time.
|
| 110 |
|
| 111 |
[CODE(MIME)[[[action]]]] 引数の値は [[RFC 2396]] で定義された絶対
|
| 112 |
URI 参照で、空以外でなければ'''なりません'''。 SOAP
|
| 113 |
はこの URI の特異性やこの URI が解決可能かどうかについて何の制限も課しません。
|
| 114 |
[CODE(MIME)[action]] 引数の目的は SOAP メッセージの意図を示すことですが、
|
| 115 |
SOAP 封筒を基にして自動的に値を計算する仕組みはありません。
|
| 116 |
言い換えれば、この値は外部で決定しなければなりません。ある方法で論理的に接続されたメッセージ型の集合、
|
| 117 |
例えば同じ[Q[サービス]]の一部を識別するために同じ値を使うことを推奨します。
|
| 118 |
URI は大域的に固有であって、時をこえて安定であることを強く'''推奨'''します。
|
| 119 |
|
| 120 |
> Use of the action parameter is OPTIONAL. SOAP Receivers MAY
|
| 121 |
use it as a hint to optimize processing, but SHOULD NOT require
|
| 122 |
its presence in order to operate.
|
| 123 |
|
| 124 |
[CODE(MIME)[action]] 引数の使用は'''任意選択'''です。 SOAP
|
| 125 |
受信者は処理を最適化するヒントとして使っても'''構いません'''が、
|
| 126 |
処理のためにこの引数が存在していることを必要とする'''べきではありません'''。

:Encoding considerations:Identical to those of "application/xml" as
|
| 130 |
described in RFC 3023 [RFC3023], section 3.2, as applied to the
|
| 131 |
SOAP envelope infoset.
|
| 132 |
|
| 133 |
[[RFC 3023]] 3.2節で [CODE(MIME)[application/xml]] について説明されていることが
|
| 134 |
SOAP 封筒情報集合にも適用されます。
|
| 135 |
|
| 136 |
>
|
| 137 |
:Security considerations:Because SOAP can carry application defined
|
| 138 |
data whose semantics is independent from that of any MIME wrapper
|
| 139 |
(or context within which the MIME wrapper is used), one should not
|
| 140 |
expect to be able to understand the semantics of the SOAP message
|
| 141 |
based on the semantics of the MIME wrapper alone. Therefore,
|
| 142 |
whenever using the "application/soap+xml" media type, it is
|
| 143 |
strongly RECOMMENDED that the security implications of the context
|
| 144 |
within which the SOAP message is used is fully understood. The
|
| 145 |
security implications are likely to involve both the specific SOAP
|
| 146 |
binding to an underlying protocol as well as the application-defined
|
| 147 |
semantics of the data carried in the SOAP message (though
|
| 148 |
one must be careful when doing this, as discussed in SOAP 1.2 Part
|
| 149 |
1 [W3C.REC-soap12-part1-20030624], section Binding to
|
| 150 |
Application-Specific Protocols).
|
| 151 |
|
| 152 |
SOAP はその意味が MIME [RUBYB[覆い子] [wrapper]]のもの
|
| 153 |
(や MIME 覆い子が使用されている文脈) から独立した応用定義のデータを伝達できますから、
|
| 154 |
MIME 覆い子だけの意味に基づいて SOAP メッセージの意味を理解できると期待するべきではありません。
|
| 155 |
従って、 [CODE(MIME)[application/soap+xml]] 媒体型を使う時は常に SOAP
|
| 156 |
メッセージが使われている文脈による安全性への影響を完全に理解することを強く'''推奨'''します。
|
| 157 |
安全性への影響は特定の下位プロトコルへの束縛にも、
|
| 158 |
SOAP メッセージで伝達されるデータの意味にも関わります。
|
| 159 |
|
| 160 |
> Also, see SOAP 1.2 Part 1 [W3C.REC-soap12-part1-20030624], the
|
| 161 |
entire section Security Considerations.
|
| 162 |
|
| 163 |
また、 SOAP 1.2 第1部の安全性に関してもご覧下さい。
|
| 164 |
|
| 165 |
> In addition, as this media type uses the "+xml" convention, it
|
| 166 |
shares the same security considerations as described in RFC 3023
|
| 167 |
[RFC3023], section 10.
|
| 168 |
|
| 169 |
加えて、この媒体型は [CODE(MIME)[+xml]] 記法を使っていますから、
|
| 170 |
[[RFC 3023]] 10章で説明されている安全性についての考察も該当します。
|
| 171 |
|
| 172 |
> The action parameter is not a security mechanism, and SHOULD NOT
|
| 173 |
be used for authentication. If the action parameter is used to
|
| 174 |
make decisions (e.g., dispatch, filtering), it is RECOMMENDED that
|
| 175 |
the basis for such decisions should be confirmed by examining the
|
| 176 |
SOAP Envelope.
|
| 177 |
|
| 178 |
[CODE(MIME)[action]] 引数は安全のための仕組みではなく、
|
| 179 |
認証のために使用する'''べきではありません'''。決定
|
| 180 |
(例えば発射、濾過) のために [CODE(MIME)[action]]
|
| 181 |
引数を使う場合は、その決定の基礎は SOAP 封筒の検査によって確認することを'''推奨'''します。
