17.14.30 src (ODSO Data Source File Path)

This element specifies the relationship whose target is the location of the external data source to be connected to a given WordprocessingML document to perform the mail merge (for a source document) or to find the associated field data (for a merged document) when the merge type, specified using the dataType element (§17.14.10), is set to native.

If this element is omitted, then no file location is specified for the data source for the current mail merge. If no relationship exists with the given relationship ID, or this relationship is not of the Mail Merge Data Source relationship type, then this document shall be considered non-conformant.

The data source location is only used under the following conditions:

  • The dataType element (§17.14.10) is set to native

  • The current application is able to use the information contained in the odso element (§17.14.25) to access the data source

[Guidance: In this case, using the data source file path in the src element provides an equal or greater amount of information for the mail merge data source for clients which can consume it. end guidance]

[Example: Consider a WordprocessingML source document containing the following mail merge data:

<w:src r:id="rId1" />

This mail merge's src element specifies via its r:id attribute value of rId1 that the external data source to be connected to the given WordprocessingML document is the data source targeted by the relationship whose Id attribute is equal to rId1. If we examine the corresponding relationship part item for the setting part, as follows:

<Relationship Id="rId1" Type="" Target="file:///c:/example_file.mdb" TargetMode="External" />

Since the relationship whose Id attribute value is rId1 specifies the source file path for the data source, that data source effectively specifies a file path of c:\example_file.mdb. end example]

Parent Elements

odso (§17.14.25)



id (Relationship to Part)

Namespace: .../officeDocument/2006/relationships

Specifies the relationship ID to a specified part.

The specified relationship shall match the relationship type required by the parent element:

  • for the contentPart element

  • for the footerReference element

  • for the headerReference element

  • for the embedBold, embedBoldItalic, embedItalic, or embedRegular elements

  • for the printerSettings element

  • for the longDesc or hyperlink element

[Example: Consider an XML element which has the following id attribute:

<… r:id="rId10" />

The markup specifies the associated relationship part with relationship ID rId1 contains the corresponding relationship information for the parent XML element. end example]

The possible values for this attribute are defined by the ST_RelationshipId simple type (§

[Note: The W3C XML Schema definition of this element’s content model (CT_Rel) is located in §A.1. end note]
