Progress Report… PBCore 1.3 for August, 2.0 in the Fall

pbcore — Tue, 06 Jul 2010 20:13:08 +0000

As previously posted, CPB has hired WGBH, Digital Dawn and AVPS to further the development of PBCore. As an interim step towards PBCore 2.0, and to accomodate PBCore’s use in CPB’s American Archive Project, we are working on version 1.3, due out at the end of July.

Attached to this post you’ll find a document that we’re working from as we consider changes to PBCore. It’s a grid which includes Digital Dawn’s requirements for changes to PBCore in the first column, and WGBH’s plan to address the changes in either 1.3 or 2.0 in the remaining columns. We’ve also incorporated comments from Dave Rice at AVPS – thanks Dave!

Many of the changes have to do with documentation and best practice examples… more so than schema changes. If you have an example best practice or suggestions for documentation clarity please pass them on to the WGBH team by commenting here on the PBCore blog or via our contact form! In addition, keep your change requests for 2.0 coming! We’ll be posting more about requests received so far in the coming days – requests submitted by July 25th will be considered for PBCore 2.0 (due to be published in early November).

The Corporation for Public Broadcasting Launches the PBCore 2.0 Development Project

pbcore — Mon, 22 Mar 2010 03:00:00 +0000

(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. For more information on the PBCore 2.0 Development Project, watch this space!

PBCore Presents at the American Archives Pilot Project Conference

pbcore — Wed, 30 Sep 2009 00:00:00 +0000

As PBCore finds itself used in a multitude of settings, databases, media information systems, and organizations, it is appropriate to “Re-Reconnoiter” with the Public Broadcasting Metadata Dictionary, particularly with regard to the American Archive Pilot Project (AAPP). At the September 2009 conference, hosted by Oregon Public Broadcasting in Portland, Oregon, PBCore was re-visited, highlighting its origins, its purpose, how it can be applied, and what could be considered better practices in the use and abuse of metadata descriptions.

The goal of the American Archive Project is stated …

… to serve as a digital repository of content produced by public television and radio, and is designed to be used by the general public, educators, broadcasters and historians. It is both preservation and a distribution system, which shares the public service orientation and sensibility of the public broadcasting system.

The AAPP is a pilot project to develop a subset of historically relevant digitized television and radio content. The goal of the project is to help CPB identify the challenges and issues encountered in the digitization of public broadcasting content as it relates to the implementation of the full Archive, which could ultimately involve scores of thousands of hours of content – both programs and back up material – reaching back as many as seven decades.

Certainly metadata plays a pivotal role. In a Re-Reconnoiter of PBCore, Paul Burrows (Media Solutions, University of Utah) recalled the genesis of the metadata dictionary and joins with the participants in exploring how its well-researched and well-defined metadata elements can be applied in describing media items and in sharing those descriptions between different information systems.

WNET-Thirteen Releases its Implementation of a PBCore Cataloging Tool

pbcore — Fri, 27 Feb 2009 00:00:00 +0000

WNET/Thirteen hereby releases the software of its PBCore Repository Project under the GPLv3 license (http://www.gnu.org/licenses/gpl-3.0.txt). The PBCore Record Repository is an online database tool built on Ruby on Rails, Sphinx search, and MYSQL that was created at WNET/Thirteen to facilitate the import, export, search, creation and modification of PBCore records according to the PBCore 1.2.1 standard (http://www.pbcore.org/PBCore/PBCoreXMLSchema.html).

For testing and evaluation a public installed version of the application can be found at http://pbcore.vermicel.li
(For administrative testing log in as username=admin and password=secret)

This work employs PBCore. The PBCore (Public Broadcasting Metadata Dictionary) was created by the public broadcasting community in the United States of America for use by public broadcasters and others. Initial development funding for PBCore was provided by the Corporation for Public Broadcasting. The PBCore is built on the foundation of the Dublin Core (ISO 15836), an international standard for resource discovery (http://dublincore.org), and has been reviewed by the Dublin Core Metadata Initiative Usage Board. Copyright: 2005, Corporation for Public Broadcasting.

Further technical documentation can be found at this website…

A current snapshot of the source code can be found at this website…

This tool is under development and feedback is appreciated.

PBCore v1.2 in on the Horizon

pbcore — Mon, 15 Dec 2008 00:00:00 +0000

A portion of the original PBCore v1.1 metadata dictionary is changing into what will be known as PBCore v1.2. The justification for changes to the PBCore schema is to better accommodate the possibility that a media asset may have multiple instantiations, all the same except for technical attributes. Thus, metadata elements that describe a media asset as a whole still exist in v1.2; however, the different attributes associated with multiple instantiations are now “containerized” under a new container called the pbcoreEssenceTrack.

That’s quite a mouthful. To preview the differences between v1.1 and v1.2, visit our web page on the PBCore XML Schema Definition (XSD). Comparative diagrams and further narrative discussion is provided there in order to highlight what will be the next edition of PBCore. An updated version of the XSD is immediately available for download from the same web page. However, the documentation and User Guide for PBCore has not yet been updated throughout the overall PBCore website. Stay tuned for that adjustment.

PBCore Resources Website now Available to help you use PBCore

pbcore — Mon, 01 Dec 2008 00:00:00 +0000

This is THE PLACE for users of the PBCore Metadata Dictionary and Schema!

The PBCore Resources Website is a place to collaborate and share experiences related to PBCore. Many of us are jumping into PBCore for cataloging and sharing information about A/V objects. We are finding it useful, but there are nuances to using PBCore properly, and in some situations, PBCore has not yet been able to fulfill all cataloging needs. Official change management is currently in the hands of the PBCore Resource Group. But everyone using PBCore in the wild either has implementation efforts to share or specific questions to ask about best practices in employing PBCore.

Jack Brighton is the Assistant Director of Broadcasting and Director of Internet Development at WILL Public Media, University of Illinois at Urbana-Champaign. He has spearheaded the effort to provide you with a place to share PBCore experiences, ask questions, and provide observations, all in a threaded discussion format. As well, announcements and links to related metadata activities and presentations are provided.

The PBCore Resources Website (http://www.pbcoreresources.org) can be considered a companion to the primary PBCore site (http://www.pbcore.org). Please visit the new user resources site, create a log-in, and begin sharing and learning about all things PBCore.

PBCore featured at IMA Session by Jack Brighton, WILL

pbcore — Fri, 01 Feb 2008 00:00:00 +0000

Jack Brighton is the Assistant Director of Broadcasting and Director of Internet Development at WILL Public Media, University of Illinois at Urbana-Champaign, where he manages web site technology and content. At the February 19-23, 2008, Conference of the Integrated Media Association, Mr. Brighton hosted a presentation on PBCore as the metadata standard for public broadcasting stations. In his session he asked such questions as: What does this mean for you? What is the purpose of a metadata standard anyway, and why PBCore? The essentials of the PBCore standard and its XML schema were covered. References were made to a variety of resources and tools, including the free File Maker Pro-based PBCore cataloging utility. Brighton also demonstrated how to use a website Content Management System to create an online video library, complete with standards-compliant web pages, RSS/Atom feeds, and PBCore XML records for each media object.

QuickStart Guide for PBCore Cataloging Tool Updated as of January 2008

pbcore — Wed, 02 Jan 2008 00:00:00 +0000

With the release of the PBCore Cataloging Tool, a QuickStart Guide was posted to the PBCore website. This Guide has been greatly expanded and in essence has become your User Guide to the PBCore Cataloging Tool.

The updated guide provides step-by-step instructions on using the Cataloging Tool, how to enter metadata, how to create User Accounts, making reports and print-outs, how to modify picklists, and the steps to both import and export XML metadata that complies with the PBCore XSD (XML Schema Definition).

Don’t just start poking around the buttons and layouts of the Cataloging Tool. Reference the QuickStart Guide for easy reading and rapid instructions. A Table of Contents is included in the Guide.

This QuickStart Guide provides instructions for both the Standard version of the PBCore Cataloging Tool (requires FileMaker Pro) as well as the Runtime versions (stand-alone, no application software required).

Duplicating a metadata record is now possible! One of the frequently asked updates to the Cataloging Tool is the ability to duplicate an individual record and then modify the duplicate to reflect only minor changes in the metadata descriptions. This is helpful when the intellectual content remains the same, but the formats (instantiation) or the intellectual property rights are the only adjustments in the data record.
