PBCore at “Describing Moving Images” Workshop
Yesterday I presented PBCore at a workshop organized by Northeast Historic Film on “Describing Moving Images.” PBCore was just one part of a day filled with FRBR, DACS and authority control discussions. Students were especially interested to learn about cataloging collections in PBCore and how to relate one PBCore record to another. My slides are [...]
PBCore presentation at IMA 2011
I presented PBCore 2.0 as part of a panel on collaboration at the IMA 22011 conference in Austin, Texas. The panel was mostly focused on case studies of collaboration — including examples between radio & print, amongst television & the arts community, and between media makers. PBCore is more of an enabling technology than an [...]
How to relate complex parts and instantiations
PBCore may be used to express multiple instantiations per work (e.g., multiple tapes containing one program). It may be done in different ways, depending on what – if any – descriptive metadata should accompany each tape. If metadata to describe the content of each tape (i.e., the program segment material) is not needed, then the [...]
Introducing PBCore 2.0
PBCore is a metadata standard designed to describe media, both digital and analog. More importantly, it was designed for the Internet and for the kinds of software applications we now use to manage, access, and share media.
How to express collections in PBCore
The introduction in PBCore 2.0 of the root element ‘pbcoreCollection’ directly addresses the need to “wrap” or collect assets for use in an XML-based publishing system like Really Simple Syndication (RSS). Use ‘pbcoreCollection’ to wrap any number of ‘pbcoreDescriptionDocument’ asset records for sharing or to express the structure of a collection of records.
How to create abstract assets (no instantiation)
PBCore 2.0 can be used to express “abstract,” or metadata-only assets. These assets simply do not have any instantiations, and might serve to represent a high level idea such as a television for which there is no single physical or digital instantiation. The descriptive metadata within such an assets may be referenced from within other [...]
How to sequence records within relationships
When PBCore is used to list related items, it can also express the nature of their interrelationships. For example, when expressing an asset within pbcoreDescriptionDocument, use the sub-element structure of pbcorePart to define segments, stories or episodes. Then utilize the element structure within ‘pbcoreRelation’ to articulate any associations between assets. <?xml version="1.0" encoding="UTF-8"?> <pbcoreDescriptionDocument xmlns="http://www.pbcore.org/PBCore/PBCoreNamespace.html" [...]
How to embed a transcript within a description
PBCore does not limit the amount of data contained in its description-oriented fields, so it’s possible to includet whole transcripts. Transcripts and other lengthy descriptions are likely to contain characters that are problematic to include in XML, however. There are two solutions: 1) wrap or surround it within a CDATA structure: <pbcoreDescription> <![CDATA[This is how [...]
