Editing document metadata
Adobe PDF documents created in Acrobat 5.0 or later contain document metadata in
XML format. Metadata includes information about the document and its contents, such as
the author's name, keywords and copyright information, that can be used by search
utilities. The document metadata contains (but is not limited to) information that also
appears in the Description tab of the Document Properties dialog box. Any changes made
in the Description tab are reflected in the document metadata. Document metadata can be
extended and modified using third-party products.
The Extensible Metadata Platform (XMP) provides Adobe applications with a common
XML framework that standardizes the creation, processing, and interchange of document
metadata across publishing workflows. You can save and import the document metadata
XML source code in XMP format, making it easy to share metadata among different
documents.
To edit document metadata:
1. Choose File > Document Properties.
2. In the Description tab, type the author's name, subject, and keywords. Use keywords that
other people might use in a search utility to locate the PDF document.
To view and edit advanced document metadata:
1. Choose File > Document Properties, and then click Additional Metadata.
2. If you want to add to the descriptive information, select Description from the list and type
information in the text boxes.
3. Click Advanced to display all the metadata embedded in the document. (Metadata is
displayed by schema--that is, in predefined groups of related information.) Display or hide
the information in schemas by clicking the plus and minus signs (Windows) or arrows
(Mac OS) next to the schema name. If a schema doesn't have a recognized name, it is
listed as Unknown. The XML name space is contained in parentheses after the schema
name.
4. To edit the metadata, do any of the following, and then click OK.
To add previously saved information, click Append, select an XMP or FFO file, and click
Open.
To add new information and replace some or all of the existing information, click
Replace, select a saved XMP file, and click Open. New properties are added, existing
properties that are also specified in the new file are replaced, and existing properties that
are not in the replacement file remain in the metadata.
To delete an XML schema, select it and click Delete.
To import metadata into a document:
Choose File > Document Properties, click Additional Metadata, and then do any of the
following:
Note: You must save a metadata template before you can import metadata from a
template.
To replace the current metadata with a template of metadata, choose a template name from
the dialog box menu.
To append the current metadata with metadata from a template, hold down Ctrl
(Windows) or Command (Mac OS) and choose a template name from the dialog box
menu.
To replace the current metadata with information stored in an XMP file, select Advanced
in the list on the left, click Replace, select the XMP file, and click Open.
To share metadata code among documents:
1. Choose File > Document Properties.
2. Click Additional Metadata, and then select Advanced in the list on the left.
3. Do one of the following:
To save the metadata to an external file, click Save. Specify the file name and location,
and then click Save. The information is stored in XMP format.
To save the metadata as a metadata template, choose Save Metadata Template from the
pop-up menu. Enter a template name, and click Save.
4. To use the saved metadata in another PDF document, open the document and use the
instructions for importing metadata into a document.
