    16. 16. Structured Data
    17. 17. Data Portability
    18. 18. Interoperability
    19. 19. Ubiquitous Connections
    20. 20. We are not just cataloging,We are enabling connection
    21. 21. Digital Media Ecology
    22. 22. “The opportunity before all of us is living up to thedream of the Library of Alexandria and then taking it a step further: Universal access to all knowledge. Interestingly, it is now technically doable. “ Brewster Kahle, founder of the Internet Archive
    23. 23. PART TWO:PBCore Origins
    24. 24. Dublin Core (ISO 15836)The Dublin Core set of metadata elements provides a small andfundamental group of text elements through which most resourcescan be described and catalogued. Using only 15 base text fields, aDublin Core metadata record can describe physical resources suchas books, digital materials such as video, sound, image, or text files,and composite media like web pages. http://en.wikipedia.org/wiki/Dublin_Core
    25. 25. Simple Dublin Core The Simple Dublin Core Metadata Element Set (DCMES) consists of 15 metadata elements: • Title • Creator • Subject • Description • Publisher • Contributor • Date • Type • Format • Identifier • Source • Language • Relation • Coverage • RightsReference: http://dublincore.org/documents/usageguide/elements.shtml
    26. 26. DC Structure:Resource: the media item in the abstract
    27. 27. DC Structure:Manifestation: a physical or digital instance of the resource
    28. 28. DC Structure:A Resource can have one and only one Manifestation
    29. 29. DC Structure:• Resource: the media item in the abstract• Manifestation: a physical or digital instance of the resource• A Resource can have one and only one Manifestation
    30. 30. The One-to-One PrincipleIn general Dublin Core metadata describes one manifestation orversion of a resource, rather than assuming that manifestationsstand in for one another. For instance, a jpeg image of the Mona Lisahas much in common with the original painting, but it is not thesame as the painting. http://dublincore.org/documents/usageguide/
    31. 31. The One-to-One principle is inefficient and/ormessy when dealing with multiple manifestations of amedia resource.Steven J. Miller, The One-To-One Principle: Challenges in CurrentPractice
    32. 32. Other Dublin Core gaps
    33. 33. Other Dublin Core gaps• DC has no place for genre
    34. 34. Other Dublin Core gaps• DC has no place for genre• DC says nothing about versioning or provenance
    35. 35. Other Dublin Core gaps• DC has no place for genre• DC says nothing about versioning or provenance• DC says little about media format
    36. 36. PBCore• built on Dublin Core• created by the American public broadcasting community for use by public media• funded by the Corporation for Public Broadcasting pbcore.org
    37. 37. PBCore Strengths• Simple like Dublin Core• Improved for moving images• Solves the one-to-one problem• Strong on technical metadata• Extensible• User community growth
    38. 38. People using PBCore• PBS & NPR & local stations• Film Archives• Northeast Historic Film• Democracy Now!• Fresh Air with Terry Gross• WNYC• The Dance Heritage Collection• Alliance for Community Media• Open Media Project• The Rock n’ Roll Hall of Fame• The American Archive• User community growing fast...
    39. 39. PBCore Community• pbcore.org• PBCore listserv• pbcoreresources.org
    40. 40. PBCore Versions• 1.0 - first public release in 2005• 1.1 - January 2007, minor fixes• 1.2 - December 2008, added pbcoreEssenceTrack• 1.3 - August 2010, added the top-level element pbcoreAssetType• 2.0 - February 2011, many improvements based on user-community input• 2.1 - Hopefully soon
    41. 41. PBCore Structure:Asset: the media item in the abstract
    42. 42. PBCore Structure:Instantiation: a physical or digital instance of the asset
    43. 43. PBCore Structure:A single Asset can have many Instantiations
    44. 44. PBCore Structure:• Asset: the media item in the abstract• Instantiation: a physical or digital instance of the asset• A single Asset can have many Instantiations
    45. 45. PBCore Instantiations
    46. 46. PBCore Instantiations• Instantiations capture technical metadata for either physical or digital media objects
    47. 47. PBCore Instantiations• Instantiations capture technical metadata for either physical or digital media objects• This is needed for provenance and preservation
    48. 48. PBCore Instantiations• Instantiations capture technical metadata for either physical or digital media objects• This is needed for provenance and preservation• Also needed by software applications that handle digital media
    49. 49. PBCore Instantiations• Instantiations capture technical metadata for either physical or digital media objects• This is needed for provenance and preservation• Also needed by software applications that handle digital media• Also important for answering the question “Where is the media object?”

    71. 71. But follow standards andprovide structured data
    72. 72. PART FOUR:PBCore 2.0
    73. 73. PBCore 1.x weaknesses• No way to record separate dates for the Asset and its Instantiations• No way to record information about multi-part Instantiations• No way to record distinct rights information for different Instantiations• No way to show relationships between Instantiations, e.g. that an MPEG4 file was made from a master video file• You can record that Harrison Ford is an Actor, but you can’t specify what role he plays in the film• You can’t identify clip information within an asset, e.g. where in the timeline a subject or person occurs• You can’t bundle together a collection of PBCore 1.x records for easy transfer to other technical systems and collections
