Parameters

strMetadata A string containing the XML metadata to be associated with the document. For more information, see

the following description.

Returns

A Boolean value: true if successful; false otherwise.

Description

Method; sets the XML metadata for the specified document, overwriting any existing metadata. The XML passed as

strMetadata is validated and may be rewritten before being stored. If it cannot be validated as legal XML or violates

specific rules, then the XML metadata is not set and

false is returned. (If false is returned, there is no way to get

more detailed error information.)

Note: Even if true is returned, the XML that is set may not be exactly the same string that you passed in. To get the exact

value to which the XML was set, use

document.getMetadata().

The format of the metadata is RDF that is compliant with the XMP specification. For more information about RDF

and XMP, see the following sources:

• The RDF Primer at www.w3.org/TR/rdf-primer/

• The RDF specification at www.w3.org/TR/1999/REC-rdf-syntax-19990222/

• The XMP home page at www.adobe.com/products/xmp/

Example

The following examples show several different legal ways to represent the same data. In all of these cases but the second

one, if the data were sent to

Document.setMetadata(), it would not be rewritten (aside from removing line breaks).

In the first example, metadata is in tags, with different schemas placed in separate rdf:Description tags:

<rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'>

<rdf:Description rdf:about='' xmlns:dc='http://purl.org/dc/1.1/'>

<dc:title>Simple title</dc:title>

<dc:description>Simple description</dc:description>

</rdf:Description>

<rdf:Description rdf:about='' xmlns:xmp='http://ns.adobe.com/xap/1.0/'>

<xmp:CreateDate>2004-10-12T10:29-07:00</xmp:CreateDate>

<xmp:CreatorTool>Flash Authoring WIN 8,0,0,215</xmp:CreatorTool>

</rdf:Description>

</rdf:RDF>

In the second example, metadata is in tags, but with different schemas all in one rdf:Description tag. This example

also includes comments, which will be ignored and discarded by the

Document.setMetadata():

1 2 ... 164 165 166 167 168 169 170 171 172 173 174 ... 564 565
