Attached is an Excel sheet aggregating the change requests gathered for PBCore 2.0 development. The three sheets represent three different modes of gathering requests (online, in conversation, etc.)
PBCore_2.0_Changes_100726.xls
We had a lot of repeat requests which is encouraging and has help us focus in on a few key changes needed for PBCore 2.0:
- Collections – how to bundle or wrap multiple PBCore records into a collection or feed
-
- Episodes/Chapters/Segmentation – how to use PBCore to represent complex records
- Multiple Carriers – how to express one work across multiple carriers (e.g. one program that spans three tapes)
- People and affiliations – how to increase PBCore’s capacity to store structured “people” data
- Controlled vocabularies – many are outdated and need review. Also support linked data protocols by allowing references to UIDs or URLs.
- Rights – how to make use of PBCore’s extension capabilities to express more complex rights metadata
Many of these issues point to the fact that PBCore 1.2 and 1.3 have not been fully documented on this site and new examples are needed.
We hope to remedy this and include 2.0 documentation as we continue to re-vamp the site this fall. If you have any comments or suggestions on how to address the issues outlined here or in the spreadsheet, please pass them along! Comment on this post or email pbcoreinfo@wgbh.org.

Progress on PBCore!
Here’s the version 1.3 XSD and documentation, which is an interim release to focus primarily on supporting upcoming American Archive projects.
PBCore v1.3:
Many thanks to those who submitted change requests for version 2.0. We’ll keep you posted as work continues to finalize the 2.0 requirements and pbcore.org redesign.

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).

(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!

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.

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

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.

This tool is under development and feedback is appreciated.

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.
