PBCore can also be used to exchange the media objects themselves. This ain't the official PBCore website For an official description of the PBCore metadata standard visit www.pbcore.org. This unofficial site is intended to move PBCore forward by the people using it. Please contribute to PBCore evolution and development Many of us are jumping into PBCore for cataloging and sharing information about A/V objects. We are finding it useful but imperfect, and clearly the PBCore standard needs further development. Change management has been administered by the PBCore Resource Group, members of which started this website. But everyone using PBCore in the wild could usefully drive the discussion. So please consider this a welcome to write something: questions, observations, projects...bring it. rss 2008-11-20T23:29:09+00:00 http://www.pbcoreresources.org/article/making_pbcore_end_user_friendly/ http://www.pbcoreresources.org/article/making_pbcore_end_user_friendly/#When:17:40:27Z Two screencast were recently added to Blip.tv that show how the Open Media Project’s Drupal modules make PBCore easier for end users.  Craig Sinclair from Amherst Community Media created a screencast that shows how to configure the PBCore module for Drupal to display customized elements in a hierarchy to users.  I added another screencast that shows how to add PBCore to any content type with CCK and how to use some simple javascript to limit the number of options show to users.  Sites using the current beta of the module can now export a node as XML as well as dump of their site specific configurations making it easier to compare how organizations are implementing PBCore in practice. The PBCore module for Drupal is still rough around the edges, but the structure is now there for anyone with even basic PHP skills to contribute.  rss 2010-08-09T17:40:27+00:00 http://www.pbcoreresources.org/article/deadline_for_pbcore_2.0_change_requests_looms/ http://www.pbcoreresources.org/article/deadline_for_pbcore_2.0_change_requests_looms/#When:20:58:24Z July 25th if the official deadline for input on the next major revision of PBCore. A release of PBCore 2.0 in November, 2010 is expected to represent a major leap forward, based on lots of change requests and research among the user community, plus where projects like the American Archive need to go. This is our chance to make sure it’s going in the most useful direction, and solving the right problems.

It seems like a good idea to open the topic for broader consideration. The Semantic Web would mostly likely be implemented by Linked Data. Using URIs and RDF, “Linked Data is about using the Web to connect related data that wasn’t previously linked, or using the Web to lower the barriers to linking data currently linked using other methods.” Those other methods would include linking things together by hand, piece by piece, which webmasters of the world can tell you doesn’t exactly scale well. So how does PBCore fit into linked data using URIs and RDF? I don’t have anything close to a complete answer, just ideas that came from the discussion. I would love some feedback to take this thing further. rss 2010-04-09T01:57:41+00:00 http://www.pbcoreresources.org/article/cpb_today_announces_the_launch_of_the_pbcore_2.0_development_project/ http://www.pbcoreresources.org/article/cpb_today_announces_the_launch_of_the_pbcore_2.0_development_project/#When:14:22:22Z (Washington, DC) - - The Corporation for Public Broadcasting today announced the launch of the PBCore 2.0 Development Project. The PBCore 2.0 Development Project will expand the existing PBCore metadata standard to increase the ability, on one hand, of content producers and distributors using digital media to classify and describe public media content (audio and video) and, on the other, of audiences to find public media content on a variety of digital media and mobile platforms. The PBCore 2.0 Development Project will also work to enhance the PBCore standard to ensure that it will be able to satisfy the demands of multiplatform digital content as well as an evolving World Wide Web. Since PBCore's development in 2005, it has become not only one of the most widely-used metadata standards in the world, but also the basis of other metadata standards. At the same time, in the last five years, the number of digital media applications that would benefit from PBCore has grown significantly. An updated PBCore will benefit not only public broadcasters, but all users of metadata standards based on PBCore. PBCore 2.0 will be managed by WGBH, AudioVisual Preservation Solutions and Digital Dawn. More information on the PBCore 2.0 Development Project will be available at http://www.pbcore.org starting in mid-April.

The XSL and a drag-and-drop Mac application of it are at http://www.avpreserve.com/pbcore-instantiationizer/. An article about the development and related issues is at http://www.avpreserve.com/pbcore-instantiationizer/pbcore-instantiationizing/. Overall transforming many of the metadata fields from MediaInfo’s output to PBCore is fairly straightforward (mediainfo:overallbitrate -> pbcore:formatdatarate, mediainfo:filesize -> pbcore:formatFileSize), but fields such as formatTracks and formatChannelConfigurations are a bit of a challenge to automate. Any feedback on this is appreciated.

The AAPP required participating stations to use PBCore as a metadata format, at least in principle. I decided to push implementation of PBCore in my AAPP content collection as far as possible using the toolset I used on a previous video archive project (Prairiefire on WILL-TV). This toolset is based on the website Content Management System called ExpressionEngine, which makes setting up a particular database structure rather easy. I set up the database structure based on PBCore elements, with controlled vocabularies reflecting the AAPP taxonomy and suggested PBCore picklists. I then created xml templates in ExpressionEngine to render my AAPP collection metadata as valid PBCore records. I then went one step further, following discussions with Dan Jacobson and David Rice, and created a PBCoreCollection wrapper containing all 235 of the PBCore item records (each as a PBCoreDescriptionDocument) in my collection. The national portal for the AAPP, being developed and hosted at Oregon Public Broadcasting, was able to simply ingest the PBCoreCollection, demonstrating the viability of this approach to aggregating a large collection from multiple content sources. This article details the methods used to accomplish this in ExpressionEngine. Similar methods could be used in Drupal, which we’re working on now. rss 2010-02-18T00:37:11+00:00
