2. Metadata records

2.1 Embedded in a digital object



• Metadata embedded in webpages
  Note: In many websites, metadata records are embedded in the source code of a webpage. Users usually will not see the metadata when they access and browse a website unless they choose to view the source code.
  In the following examples, please choose View: Source from the browser.
  • Apple Computer, Inc. website | link to site --> view source | cached pdf file |
  • IBM website| link to site --> view source) | cached pdf file |
  • Microsoft website | link to site --> view source) | cached pdf file |
  • A research report | link to site --> view source | cached pdf file |
    
    
• Metadata embedded in digital images
  Note: Some image software allows metadata records about an image to be recorded and attached in the image. When an image is viewed from the software application, it looks as if a record is embedded in the digital image. Values in some elements are automatically captured by the software while others are controlled by metadata creators.
  • An example from Photoshop CS: | cached: Metadata record; keywords; original image |

2.2 Metadata records displayed from databases

Note: Bibliographic databases, digital collections, and digital repositories store metadata records in databases and display the records with a more user-friendly interface. The following examples show how a record could be presented to users and how it is actually encoded or stored in a database.

• Library bibliographic catalogs
  
  • Examples from the KentLINK OPAC:
    |cached: Displayed bibliographic record and MARC record |
    
    
• Digital collections
  • Examples from the OhioLINK Digital Media Database:
    |cached: Image and Full metadata record |
    
    
    
  • Examples from the Worthington Memory collection, (Worthington, Columbus, Ohio):
    |cached: Search results; Expanded record; Dublin Core record |
    
    
  • An Example from the GREEN (Green's Functions Digital Library) project, Kent State University
    |link: cached pdf file |
  
  
  
  • Example from the Alexandria Digital Library (ADL), UC Santa Barbara
    
    • Display records at ADL-- cached PDF files: Standard report | Standard XML
      
    • Records stored at the National Science Digital Library (NSDL) Metadata Repository
      
      
• Digital repositories
  
  • Examples from the National Science Digital Library (NSDL)
    • The same ADL record displayed at the NSDL-- cached PDF file: metadata record
      
      
    • To see other examples in NSDL:
      • www.nsdl.org => type your search term, for example, "planet Mars" => click on "View all related information" at the item you select.
        
        
  • Example from American Memory, Historical Collections from the National Digital Library
    
    • cached PDF file: Image thumbnail and full metadata record
      
      
    • To see other examples in the American Memory collection:
      • http://memory.loc.gov/ammem/index.html ==> search or browse

2.3 Sample records provided by metadata standards or guidelines

Note: Metadata standards usually provide the best practice guides in their specifications. The examples provided focus on the contents rather than the formats. It ensures that metadata elements, structure, and value spaces specified by a standard are correctly understood and controlled when applied to real situations. It is not their intention to provide format guidelines as to how a record should be encoded or displayed.

• Dublin Core
  http://dublincore.org/documents/dc-citation-guidelines/
  • See examples provided in this Guidelines for Encoding Bibliographic Citation Information in Dublin Core Metadata.
    
    
• CDWA (Categories for the Description of Works of Art), Getty
  http://www.getty.edu/research/conducting_research/standards/cdwa/examples.htm
  • See over 100 examples under "Catalog Examples".
    
    
• VRA Core 3.0 (Visual Resource Association (VRA) Core Categories)
  http://www.vraweb.org/projects/vracore3/examples.html
  
  • The last section of the standard included several examples.
    Pay attention to the data sets in Example 3 that describe a chair documented by a photograph. The photograph was later copied to a slide format and scanned to create a digital image.
    
    
• VRA Core 4.0 Beta (Visual Resource Association (VRA) Core Categories)
  http://gort.ucsd.edu/escowles/vracore4/
  • Metadata records for 13 works are provided. For each work, there is a html display record, a full VRA record, and a record encoded with XML.
    
    
• Cataloguing Culture Objects (CCO) (website: http://www.vraweb.org/ccoweb/cco/index.html)
  • Book Appendix A: Examples. 178 examples are available
