下面是一些基本事务对应的Soap信息

XDS Register Document Set transaction

 This transaction must move registry metadata from the Repository actor to the Registry actor. There are no document attachments since the documents have already been deposited in the Repository by this time. This transaction just moves a single element, the bundle of registry metadata.

Since there is only one item of payload, the SOAP with Attachments format is not used. Instead the simpler SOAP format is used. Below is an example of this format. It contains an HTTP header and a HTTP Body.

HTTP Header - note the following header fields:

• SOAPAction is required
• Content-Type must be as shown

HTTP Body - note the following points:

• It is entirely XML
• The outer-most layers of XML are SOAP
• Next is the registry SubmitObjectsRequest
• Within the SubmitObjectsRequest is the registry metadata
• Notice the namespace definitions on SubmitObjectsRequest.

XDS Provide and Registry Document Set transaction

This transaction is used to move documents and metadata from the Document Source actor and the Document Repository actor. Since more than one element of data must be encoded, a coding scheme must be employed that is capable of wrapping multiple elements. That coding scheme is SOAP with attachments.

HTTP Header - note the following header fields:

• SOAPAction is required
• Content-Type has a new part, the boundary sting
• Within Content-Type is the boundary string to be used as a delimiter between the "parts". This string is typically generated randomly by toolkits that generate this format.
• The final use of this delimeter has an extra "--". This is critical for some parsers.

HTTP Body - note the following points:

• The body has multiple parts separated by the boundary string
• Each part has a Content-Type header and optionally a Content-ID header
• The Content-ID header is an "ID" for this piece of content within the message. The "ID" is always surrounded by angle brackets "< >".
• The first part is always the metadata. See XDS Registry Document Set transaction above for details.
• An ExtrinsicObject in the metadata representing and XDSDocumentEntry can have a id attribute with this "ID" value. This links the ExtrinsicObject in metadata to real document content in the message.
• In the example below, the ExtrinsicObject XML element has an id attribute with the value "doc_1". This is interpreted as a "pointer" to the message part with Content-Id equal to <doc_1>.
• A submission can contain any number of documents

Using MIME Multipart/Related as a document format

The MIME Multipart/Related format is used as a document format within XDS-I. 

Content-Type: Multipart/Related; boundary=example-2

--example-2
Content-Type: text/plain

Text related to the PDF below is inserted here.
--example-2
Content-Type: application/pdf
Content-Transfer-Encoding: BASE64

BASE64 encoded PDF goes here
--example-2--

The first line is a Content-Type header which must have as its first value the string "Multipart/Related" and an additional part must document the boundary string to be used. The blank lines (technically \r\n) are used to indicate "end of header". One of the parts must be of type text/plain and the other must be "application/pdf" and the contents of this part must be the BASE64 encoded contents of the relevant PDF.
