Viewing Document Metadata In Acrobat 5.0, Adobe PDF files contain Document Metadata in XML format.This Document Metadata contains (but is not limited to) information that is also in the Document Properties. Any changes made in the Acrobat Document Properties dialog box are reflected in the Document Metadata. Because Document Metadata is in XML format, it can be extended and modified using third-party products. You can copy and paste the Document Metadata XML source code. To view the Document Metadata: 1 Choose File > Document Properties > Document Metadata. 2 The Document Metadata dialog box displays all the metadata embedded in the document. (Metadata is displayed by schema-that is, in predefined groups of related information.) The information associated with each schema is visible by default; it can be hidden by clicking the triangle 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. 3 To view the XML code, click View Source.You can cut, copy, and paste XML code from the Metadata Source View dialog box. Click OK to return to the Document Metadata dialog box. 4 Click OK to close the Document Metadata dialog box, and click Cancel to close the dialog box without making any changes. Encrypting PDF files Acrobat Self-Sign Security encrypts PDF files, allowing you to securely share those files with a list of recipients you define.You must have a Trusted Certificate for each recipient to whom you want to send your encrypted file.You can also define the recipient's level of access to the file-for example, whether the recipient can edit, copy, or print the files.You should be sure that the certificate is intended for encrypting PDF files.This will be the case, if the certificate comes from the Self-Sign Security plug-in on the recipient's machine. However, if you import a certificate from any p7c file into Self-Sign list of trusted certificates, the private key that corresponds to this certificate may not be accessible from the recipient's Acrobat program. (See "Building a list of trusted certificates" on page 207.) You encrypt a PDF file automatically when you create a list of recipients for that file using Adobe Self-Sign Security. Note: For information on Acrobat Self-Sign, see "About Acrobat Self-Sign Security" on page 197. For information on Trusted Certificates, see "Managing user certificates" on page 205. To create a recipient list and encrypt a file: 1 With your PDF file open, choose File > Document Security. 2 In the Document Security dialog box, choose Acrobat Self-Sign Security for the security handler.
