Following are examples of metadata and how it can help photographers, both now and in the future. You can use the File Info dialog box to view and append or replace metadata in image files. The basic File Info dialog box in Photoshop CS Embedded metadata can be in XMP form and is also aliased to other schemas for backward compatibility. To edit PDF metadata online with the help of PDF Candy, start with uploading of the file for posterior processing: “Add file” button will let you upload the file from your device; alternatively you may use the drag and drop mechanism for that. . Explore different types and functions of metadata (administrative, technical, administrative, etc.) Exercise: Examine three digital library instances, discuss differences in user approach and experience, and look for examples of metadata use. For example, a book's title and author is metadata. Metadata can be many kinds of information - a location, a date, or a catalog item number.

PDFdocuments created in Acrobat 5.0 or later contain document metadatain XML format. Metadata includes information about the documentand its contents, such as the author’s name, keywords, and copyrightinformation, that can be used by search utilities. The documentmetadata contains (but is not limited to) information that alsoappears in the Description tab of the Document Properties dialogbox. Document metadata can be extended and modified using third-partyproducts.
The ExtensibleMetadata Platform (XMP) provides Adobe applicationswith 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 inXMP format, making it easy to share metadata among different documents.You can also save document metadata to a metadata template thatyou can reuse in Acrobat.
- Choose File > Properties, and clickthe Additional Metadata button in the Descriptiontab.
- Click Advanced to display all the metadata embedded inthe document. (Metadata is displayed by schema—that is, in predefinedgroups of related information.) Display or hide the informationin schemas by schema name. If a schema doesn’t have a recognizedname, it is listed as Unknown. The XML name space is contained inparentheses after the schema name.
- Choose File > Properties, click theDescription tab, and then click Additional Metadata.
- To edit the metadata, do any of the following, and thenclick OK.
To add previously saved information, click Append, select an XMP or FFO file, and click Open.
To add new information and replace the current metadata with information stored in an XMP file, click Replace, select a saved XMP or FFO 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 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 in the upper right corner.
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 file (XMP) from the dialog box menu in the upper right corner.
- Choose File > Properties, click theDescription tab, and then click Additional Metadata.
To save the metadata to an external file,click Save and name the file. The metadata is stored as a file inXMP format. (To use the saved metadata in another PDF, open thedocument and use these instructions to replace or append metadatain the document.)

Metadata Examples Pdf File
by Eric Mc Guire, Support Engineer
Your PDF documents are only as good as your users’ ability to find them so they can make use of the information within them. That’s where metadata can help.
Metadata means ‘data about data’. It offers additional information about your file, such as the fact that you’re the author, when you created your file, the software you used to create the file, the PDF document’s subject, and more.
Using metadata is especially helpful if your company uses a content management system, because those software systems provide features specifically used to search metadata beyond a document’s file name.
Metadata fields include:
- Document title (different than the file name)
- Author
- Subject
- Keywords
- Base URL
- Creator (the application the file was created in)
- Created date
- Modified date
- File size
- File name
Search Pdf Metadata
Each of these pieces of information can help users find PDF documents. As an example, you might need to find a PDF document and only know the name of the author. If the PDF file has proper metadata inserted into it, you can search for the author’s name to narrow down the files that she created or target the exact one.
So how do you go about customizing the metadata in your PDF documents? It’s pretty simple.
How to view the metadata in a PDF file
If you’re using Foxit Reader to view metadata in a PDF document, open the document and choose File > Properties and then select the Description tab. The metadata will show up right there.
How to add or edit metadata
Lots of content creation applications, such as Microsoft Word and Adobe Photoshop, allow you to create metadata for your files. Using Adobe Photoshop, for example, automatically adds the name of the author and the date it was created it. To add metadata, simply open the File menu and go to File Info.
PDF editing tools, such as Foxit PhantomPDF, also allow you to add metadata or edit it. Which means you’ve got an easy way to ensure your PDF documents are easily found when anyone is looking for them. And of course, that’s the best reason of all to use metadata effectively in your PDF documents.
