http://www.pbcore.org/announcements.html Recent updates, news, and announcements about the PBCore Metadata Dictionary Project. en-us 2005 Tue, 23 Mar 2010 00:12:00 MDT 09 Oct 2009 10:12:00 MST pburrows@media.utah.edu (Paul Burrows) pburrows@media.utah.edu (Paul Burrows) http://www.pbcore.org/favicon.ico http://www.pbcore.org/index.html http://www.pbcore.org/announcements.html#cpbpbcore2 (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! http://www.pbcore.org/announcements.html#pbcoreataapp 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, 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. Both PDF and QuickTime movie versions of the presentation are available for download. http://www.pbcore.org/announcements.html#wnettool Written by DaveRice on Friday, February 27, 2009. 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 tool is under development and feedback is appreciated. David Rice, Digital Media Archivist, WNET/Thirteen http://www.pbcore.org/announcements.html#pbcore1-2soon A portion of the original PBCore v1.1 metadata dictionary is changing into what will be known as PBCore v1.2. To preview the differences between v1.1 and v1.2, visit our web page on the PBCore XML Schema (XSD) (http://www.pbcore.org/PBCore/PBCoreXMLSchema.html#diagram). 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. http://www.pbcore.org/announcements.html#pbcoreresourcesite 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. 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. http://www.pbcore.org/announcements.html#IMA2008 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. http://www.pbcore.org/announcements.html#catalogingtoolruntimes The PBCore Cataloging Tool based on FileMaker Pro databases was made available for download earlier in 2007. The tool is a fully featured database file that complies with the PBCore metadata dictionary. It provides a PBCore compliant method for describing media assets and has direct links to the PBCore User Guide for assistance. The Tool also offers export and import of XML files of metadata that are based on the PBCore XSD (XML Schema Definition). As a database file, the Tool required the user to purchase and install the actual FileMaker application in order to launch and run the Tool. We call this iteration of the Tool the Standard Version. The PBCore project is putting the finishing touches on Runtime Versions. The Runtime Versions do not require the FileMaker application. They are stand-alone, self-launching files and are available in two editions, one for the Macintosh and one for the Windows operating systems. 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. The links to download these files are to be found at http://www.pbcore.org/PBCore/PBCore_Tools.html#tools http://www.pbcore.org/announcements.html#quickstartupdated 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.

In the December1 7, 2007 issue, Marcia Brooks (project manager for the PBCore project during the last several years) writes about the PBCore Metadata Dictionary. The article updates us on the past, current, and future events surrounding PBCore and its usage across many different metadata communities. http://www.pbcore.org/announcements.html#catalogingtool Need to catalog media items using the PBCore Metadata Dictionary? From our PBCore User Guide (http://www.pbcore.org/PBCore/PBCore_Tools.html) you may now download the FileMaker Cataloging Tool along with two read me files (for end-users, and for admins/developers who want to customize the tool). An audio/video overview of the Cataloging Tool is available in our fourth training module, PBCore 104 (http://www.pbcore.org/PBCore/PBCore_TrainingMaterials.html#trainingfiles). From within the Cataloging Tool, each metadata field is accompanied by a direct hyperlink to its definition and guidelines for usage in the PBCore User Guide. The PBCore Users Group listserv (sign-up available at PBCore.org) is a resource to support the PBCore community of practice -- please share your questions, experiences and innovations. http://www.pbcore.org/announcements.html#mappings How do the PBCore elements map to other metadata dictionaries and schemas? In our PBCore User Guide (http://www.pbcore.org/PBCore/PBCore_Mappings.html) we provide 15 entries related to the mapping of PBCore elements to other metadata systems. Some of these documents we have authored from scratch. Others are documents generously provided by other librarians, information science researchers, public broadcasting entities, and long-time participants in the PBCore Metadata Dictionary Project. In some cases, actual mappings are still being vetted and refined, but will be posted as soon as they are "green lighted." You will notice that some mappings are not strictly about PBCore, such as the Dublin Core crosswalk to MPEG-7 and MARC 21. We have included these seminal works because they act as bridging documents for future PBCore comparisons and mappings. PBCore is specifically mapped in detail for both Dublin Core and IEEE LOM Learning Object Metadata (where you will find over a dozen elements related to the integration and utilization of media items in educational settings). http://www.pbcore.org/announcements.html#samplemetadatarecords What do Complete Metadata Records look like with PBCore? (http://www.pbcore.org/PBCore/PBCore_SampleRecords.html) In our PBCore User Guide, the Full Documentation and Cheat Sheet Documentation for the PBCore metadata elements provide numerous examples of data entries. These examples are viewed on an element-by-element basis. We have now posted samples as complete metadata descriptions on a record-by-record basis where all the PBCore elements are populated with descriptive data for a given media item or object. Our sample records catalog different media types and variations on "repeating elements and containers." The layout of our sample metadata records follows the structure of PBCore in an easy to read format, showing each element within its container, organized by Content Class (Intellectual Content, Intellectual Property, Instantiation, and Extensions). If there is a question about the definition and best practice for using an element, each is hyperlinked to its original documentation in the PBCore User Guide. Every Sample Metadata Record provides a link to a complete XML version of the sample descriptions, in accordance with the PBCore XSD (XML Schema Definition). http://www.pbcore.org/announcements.html#caseexamples How is PBCore being used in the Real World? (http://www.pbcore.org/PBCore/PBCore_CaseExamples.html) Over several years, representatives from Public Broadcasting public media and related institutions joined as a Working Group to craft what has become Version 1.1 of the Public Broadcasting Metadata Dictionary of descriptors for radio and television programs, as well as related digital and non-digital text, images, and rich media files. In the presentation of the PBCore elements in the PBCore User Guide, each metadata element is identified by properties, including Name, Definition, Refinements and Encoding Schemes, Guidelines for Usage, Obligation to Use, Repeatability, Type of Data, and Examples. While the examples included with the element-by-element definitions offer "samples at a glance," what is missing are actual Use Cases outlining how various stations and organizations implement PBCore elements in their own workflows, program descriptions, production activities, promotions, and sharing. Reviewing actual implementations of the PBCore is valuable because it shows how our metadata building blocks are used in real-world applications. Included in our Case Examples are PBS, Public Radio Satellite Service-ContentDepot, HD Public Radio Program Service Data (PSD), NDIIP, MIC-Moving Image Collections, Wisconsin Public Television Media Library Online, Democracy Now!, Iowa Public Television, Traffic and Program Scheduling Software, KQED Public Radio, Stanford University News Service, WGCU Public Media, WILL AM-FM-TV, NET-Nebraska Learning Services, OMN-Open Media Network, the Utah Education Network, and the NETA MediaExchange Project. http://www.pbcore.org/announcements.html#training104 So far, our previous Training Sessions 101-103 dealt with defining metadata, examining the PBCore metadata elements, and reviewing the PBCore XML Schema (XSD). Now Session 104: The PBCore Cataloging Tool is available for On-Demand viewing. The session discusses the PBCore FileMaker Pro cataloging tool (releasing September 28, 2007 for download from http://www.pbcore.org/PBCore/PBCore_Tools.html). The tool facilitates the markup of descriptions for media objects and has XML data import and export capabilities for sharing and interoperability, based on the PBCore XML Schema Definition (XSD). The on-demand versions of the trainings are posted as PowerPoint, Acrobat PDF, QuickTime Movie, Audio MP3, and iPod Compatible Video. To download, visit our web page http://www.pbcore.org/PBCore/PBCore_TrainingMaterials.html. http://www.pbcore.org/announcements.html#usergroup Many of you have already joined the PBCore Listserv. We now have a new dedicated listserv group that is specifically devoted to the questions, comments, and advice of those who are actually using the PBCore metadata dictionary, or who are about to implement it. The regular PBCore Listserv will continue as a way to communicate announcements and updates on the overall PBCore project. The new PBCore User Group Listserv is intended as a forum for PBCore users to share successes, ask for help when stuck, find inspiration in the way others are implementing PBCore technology, and help others avoid the hurdles that some have already experienced and overcome. For more information on subscribing to the PBCore User Group Listserv, go to http://www.pbcore.org/announcements.html#usergroup http://www.pbcore.org/announcements.html#training104 So far, our previous Training Sessions #1,#2 and #3 dealt with defining metadata, examining the PBCore metadata elements, and introducing the PBCore XSD (XML Schema Document) used to export and import metadata files between information systems. Training #4 is now scheduled as part of our virtual, WebEx, online sessions. Mark your calendars and watch our announcements when registrations are open. PBCore Session 104. The PBCore Cataloging Tool-- Wednesday, September 19, 2007 at 2:00pm EDT, Repeated live on September 20, 2007 at 2:00pm EDT. Discussion of tools that use PBCore, specifically, the PBCore FileMaker Pro cataloging tool we've developed (releasing in mid-September 2007). The tool facilitates the markup of descriptions for media objects and has XML data import and export capabilities for sharing and interoperability, based on the PBCore XML Schema Definition (XSD). http://www.pbcore.org/announcements.html#training103 The on-demand versions of the PBCore training 103 are posted as PowerPoint, Acrobat PDF, QuickTime Movie, Audio MP3, and iPod Compatible Video. To download, visit our web page http://www.pbcore.org/PBCore/PBCore_TrainingMaterials.html. http://www.pbcore.org/announcements.html#moretraining So far, our previous Training Sessions Nos. 1 and 2 dealt with defining metadata and examining the PBCore metadata elements. Training Sessions Nos. 3 and 4 are now scheduled. Session 3 is "The PBCore XML Schema: What It Is and How It Works." Session 4 is "Cataloging Tools for PBCore: What's Available and How They Work." To find out more and sign up for these WebEx online webinars, go to http://www.pbcore.org/PBCore/PBCore_TrainingMaterials.html http://www.pbcore.org/announcements.html#vide2007 At the 2007 conference of the Southeastern Universities Research Association (SURA) and the Video Development Initiative (ViDe)(March 26-29), the release of PBCore Version 1.1 was highlighted in a presentation by Paul E. Burrows reviewing the current activities of the PBCore Project. Attendees were updated on the advocacy, promotion, and adoption engagements of PBCore with industry groups, national and local program producers, PBS, NPR, Content Depot, and vendors of traffic and scheduling software. Changes made from version 1.0 to 1.1 were explained, as were the importance of the PBCore XML Schema Definition document (XSD). New training opportunities for PBCore, both online and on-demand, were announced. As well, a call-to-action was made to the attendees to participate in PBCore's Community of Practice by joining the Listserv. The presentation can be downloaded as a PDF document from the PBCore Resources and Links page at http://www.pbcore.org/resources/index.html http://www.pbcore.org/announcements.html#xsdpublished The PBCore v1.1 XML Schema Definition (XSD) is published! For a complete discussion on what this means for the advancement of PBCore and facilitating our Community of Practice, see http://www.pbcore.org/PBCore/PBCoreXMLSchema.html. Since the initial publication (April 2005) of the Public Broadcasting Metadata Dictionary (PBCore), many stations, organizations and information systems have begun to use its 53 elements to describe the intellectual content, property rights, and instantiations (formats) of their media items. At the same time, the PBCore project has been perfecting its XML Schema Definition (XSD) (for a discussion of XSD see the PBCore XML Schema web page http://www.pbcore.org/PBCore/PBCoreXMLSchema.html). This XSD is the main framework upon which all the PBCore elements, their relationships, vocabulary picklists, and data types are organized and defined. The purpose of building an accurate and meticulous XSD is to ensure that when PBCore compliant metadata descriptions are shared between data systems, the contributing system and the receiving system are both able to "machine read" and faultlessly interpret and display the descriptions. http://www.pbcore.org/announcements.html#download The first two training sessions for PBCore are available for on-demand download. Go to http://www.pbcore.org/PBCore/PBCore_TrainingMaterials.html#trainingfiles. Each session has multiple options: (1) PowerPoint (zipped file); (2) PDF document of the PowerPoint slides; (3) QuickTime movie; 640x480 (zipped file); (4) iTunes/iPod compatible movie; 320x240 (zipped file); (5) MP3 audio file (zipped file). Sessions 3 and 4 will be scheduled soon. Watch for announcements on the PBCore website (http://www.pbcore.org) as well as on the PBCore Listserv. http://www.pbcore.org/announcements.html#rssfeed We have been undertaking some behind-the-scenes technical updates for the PBCore website, none of which impact how you currently access http://www.pbcore.org or http://pbcore.org (but which should improve performance). Nevertheless, the RSS Feed Address you use to subscribe to the PBCore RSS Feed does have to change. If you use an RSS news reader and now subscribe to our RSS Feed, please update or create a new feed subscription to the following XML address: NEW RSS FEED ADDRESS = http://www.pbcore.org/RSS/PBCoreUpdates.xml For more information about RSS feeds in general, please access our web page WHAT IS RSS? http://www.pbcore.org/RSS/whatisrss.html http://www.pbcore.org/announcements.html#PBCore_Version11 We are excited to announce that Version 1.1 of PBCore is released. Since the initial publication (April 2005) of the Public Broadcasting Metadata Dictionary--PBCore v1.0, many stations, organizations and information systems have used its 48 elements to describe the intellectual content, property rights, and instantiations/formats of their media items and intellectual properties. During this last year, the PBCore project was finalizing its XML Schema Definition (XSD). This XSD is the main framework upon which all the PBCore elements, their relationships, vocabulary picklists, and data types are organized and defined. The purpose of building an accurate and meticulous XSD is to ensure that when PBCore compliant metadata descriptions are shared between data systems, the contributing system and the receiving system are both able to "machine read" and faultlessly interpret and display the descriptions. In the process of creating the PBCore XSD, we determined that enhancements to the underlying structure of PBCore were necessary, resulting in PBCore v1.1. For the most part, these enhancements are related to binding together related metadata elements (such as Title and TitleType) into new "Element Containers." In a hierarchical arrangement, each Element Container collects and houses associated "child" Elements that are thematically related. Basically, what was a "flat" arrangement of the 48 PBCore elements has become a more structured "hierarchical" model of 53 elements, arranged in 15 containers and 3 sub-containers, all organized under 4 content classes. The PBCore Website, http://www.pbcore.org, is now re-edited in support of v1.1 of the metadata elements... 01. The PBCore USER GUIDE has been revised and updated to reflect the changes in PBCore v1.1, http://www.pbcore.org/PBCore/UserGuide.html 02. FULL DOCUMENTATION is provided on an element-by-element basis 03. A CHEAT SHEET is added as a quick reference guide to using the elements for cataloging 04. Different VIEWS offer enhanced "at-a-glance" snapshots of the elements in v1.1: (a) Graphical View; (b) Listed Alphabetically; (c) Listed by Content Class; (d) Listed by Obligation to Use (mandatory elements); (e) Hierarchies and Element Interdependencies 05. Significant CHANGES from PBCore v1.0 to v1.1 are itemized 06. SAMPLE METADATA RECORDS for different media types are provided 07. CASE EXAMLES of PBCore Implementations have been researched and posted 08. MAPPINGS of PBCore to other metadata standards and schemes are documented 09. A CATALOGING TOOL to facilitate data entry and interoperability with other information systems is available 10. The PBCore v1.1 XML SCHEMA DEFINITION (XSD) is published 11. TRAINING SESSIONS for PBCore (live WebEx and On-Demand) are available The underlying meaning and attributes of the PBCore elements are not changing. However, their interdependencies and structural arrangements are, along with some modifications to data entry options. We are confident the improvements in PBCore v1.1 will greatly enhance its usability by Public Broadcasting communities and certainly will improve the precision and interoperability potential in sharing metadata between various information systems. http://www.pbcore.org/announcements.html#neta2007 At the 2007 conference of the National Educational Telecommunications Association (NETA) (January 25-28), the new release of PBCore Version 1.1 was highlighted in a presentation by Paul E. Burrows reviewing the current activities of the PBCore Project. Attendees were updated on the advocacy, promotion, and adoption engagements of PBCore with industry groups, national and local program producers, PBS, NPR, Content Depot, and vendors of traffic and scheduling software. Changes made from version 1.0 to 1.1 were explained, as were the importance of the PBCore XML Schema Definition document (XSD), soon to be published. New training opportunities for PBCore, both online and on-demand, were announced. http://www.pbcore.org/announcements.html#training As many of you are aware, a metadata dictionary used to describe the intellectual content, rights, and formats of public broadcasting media has been developed and made available for your use. It is called PBCore, or Public Broadcasting Core of Metadata Descriptions (http://www.pbcore.org). PBCore is being used in public radio and television and beyond to describe, publish and share content, and to allow others to find your content. Sounds like a great idea, right? But what, exactly, is a metadata dictionary? For that matter, um... what IS PBCore? Learn the answers to these and other questions at a one-hour on-line presentation hosted by the PBCore Project at WGBH. If you would like to participate in these training presentations, please go to http://pbcore.webex.com, click on the "Upcoming" tab and register for the session you want to attend. Note that you will be prompted to install the WebEx Java applet once you have completed the registration form. You may install the applet at any time prior to the session. Please contact Geoff Freed at geoff_freed@wgbh.org if you have questions about registration or the presentation itself. After the live sessions, you can review the PowerPoint presentations and audio recordings on-demand by accessing our web page PBCore Training, http://www.pbcore.org/PBCore/PBCore_TrainingMaterials.html. "Introduction to PBCore" is the first presentation in a series being developed by the PBCore Project. Upcoming sessions will focus on how to describe a media item using PBCore metadata descriptors and the resources being developed to support your use of PBCore, including the PBCore XML schema and the implementation of PBCore through cataloging tools (for more information see our page about PBCore Training http://www.pbcore.org/PBCore/PBCore_TrainingMaterials.html). The PBCore Project is administered by the Carl and Ruth Shapiro Family National Center for Accessible Media at WGBH (NCAM). Initial PBCore development, advocacy and training is funded by the Corporation for Public Broadcasting. http://www.pbcore.org/announcements.html#userguide With the publication of version 1.1 of PBCore, our online User Guide has been re-edited and updated. The PBCore User Guide (http://www.pbcore.org/PBCore/UserGuide.html) now includes the following sections... 01. FULL DOCUMENTATION is provided on an element-by-element basis 02. A CHEAT SHEET is added as a quick reference guide to using the elements for cataloging 03. Different VIEWS offer enhanced "at-a-glance" snapshots of the elements in v1.1: (a) Graphical View; (b) Listed Alphabetically; (c) Listed by Content Class; (d) Listed by Obligation to Use (mandatory elements); (e) Hierarchies and Element Interdependencies 04. Significant CHANGES from PBCore v1.0 to v1.1 are itemized 05. SAMPLE METADATA RECORDS for different media types are provided 06. CASE EXAMLES of PBCore Implementations have been researched and posted 07. MAPPINGS of PBCore to other metadata standards and schemes are documented 08. A CATALOGING TOOL to facilitate data entry and interoperability with other information systems is available 09. The PBCore v1.1 XML SCHEMA DEFINITION (XSD) is published 10. TRAINING SESSIONS for PBCore (live WebEx and On-Demand) are available http://www.pbcore.org/announcements.html#cheatsheet The existing online PBCore User Guide (http://www.pbcore.org/PBCore/UserGuide.html) provides element-by-element definitions and properties in 53 different web pages, one page per element. This is considered as our Full Documentation. Many PBCore users have also requested a quick reference guide to the elements in order to to assist catalogers when entering descriptions for media items. A Cheat Sheet for PBCore v1.1 is now published (http://www.pbcore.org/PBCore/PBCore_OnePageCheatSheet.html). It is a single web page with the PBCore elements organized according to their Content Classes (Intellectual Content, Intellectual Property, Instantiation, and Extensions). The Cheat Sheet includes an alphabetical index at the top of the page, with interactive jumps to a particular element's description. Each element begins with example data entries, followed by a brief definition for that element and guidelines for usage. A PDF of the Cheat Sheet for PBCore v1.1 has been generated. This document includes the "bookmark" functionality of PDFs to facilitate moving around the 38 pages. Additionally, the PDF's alphabetical index harvested from the online version of the Cheat Sheet offers the same interactive jumps to particular element descriptions within the PDF document. A link is provided at the top of the Cheat Sheet in order to download the PDF. http://www.pbcore.org/announcements.html#PBCore_PBSTech06 With version 1.0 of the PBCore metadata dictionary published via its website (http://www.pbcore.org), the project has moved into a new phase. Through the next 18-months, funded by CPB and managed by NCAM, the National Center for Accessible Media, PBCore will aggressively engage in advocacy, training, implementation, and support activites in order to build a "Community of Practice" for the dictionary and its adoption by users, vendors, and standards groups. http://www.pbcore.org/announcements.html#PBCoreXMLv1 The XSD (XML Schema Definition) for the PBCore metadata dictionary is available in draft form and is ready for comment from interested parties. The schema is available in both pdf and Word doc (zipped) formats. To comment on the XML Schema Definition, please submit feedback and suggestions through our PBCore listserv. Background Information: The Public Broadcasting Metadata Dictionary (PBCore) Version 1.0 is the product of a number of years of collaboration involving local and national television and radio organizations, numerous constituencies and related disciplines. It is intended as a common metadata and cataloguing resource for public broadcasters and associated communities. PBCore Version 1.0, as published on the PBCore website on April 1, 2005, defines 48 metadata elements, and remains current and valid. (See http://www.pbcore.org for detailed information and extensive tutorials.) There is a need to express the PBCore dictionary elements and definitions in a concise and structured manner to enable integration and interoperability across multiple systems. The PBCore XML Schema builds on the entire PBCore effort to date and takes this step. This document attempts to provide background rationale and discussion, along with the complete PBCore XML Schema and an example PBCore asset document (record). http://www.pbcore.org/announcements.html#listserv For e-mail announcements about PBCore events, features, and updates, subscribe to our PBCore Listserv.

To subscribe, see the instructions on the "Contacts" web page for PBCore (http://www.pbcore.org/contacts/) http://www.pbcore.org/announcements.html#pbstech2005 PBCore was the subject of three presentations during the PBS Technology Conference (April 14-16) and the National Association of Broadcasters Conference (April 18-21). Links are provided to read or view PDF and QuickTime (slideshow) movie versions of the presentations. http://www.pbcore.org/announcements.html#01 The Working Groups for the Public Broadcasting Metadata Dictionary Project and the Corporation for Public Broadcasting are enthusiastically pleased to announce that the PBCore set of media descriptors, v1.0, is now published! The dictionary of metadata elements, their descriptions, and usage guidelines are ready for review in the PBCore User Guide. http://www.pbcore.org/announcements.html#03 Kentucky Educational Television was part of the PBCore Test Implementation Phase and became an early adopter of our metadata dictionary. http://www.pbcore.org/announcements.html#04 Download the PDF version of the flyer for PBCore v1.0 http://www.pbcore.org/announcements.html#05 There was a sincere belief by all participants in the Test Implementation Phase that their organization, and public broadcasting at large, needs something like the PBCore to be widely available, and in use by a majority of public broadcasters. http://www.pbcore.org/announcements.html#06 Beginning in January 2002 a team of public broadcasting station and national network representatives and invited guest experts worked to develop a draft metadata dictionary for public broadcasting. This effort, managed by WGBH/Boston under a grant from the Corporation for Public Broadcasting, resulted in a draft "Public Broadcasting Core Metadata Elements Dictionary" completed by the project's "Dictionary Team" in January of 2004. Controlled vocabulary "refinements" for each of the metadata elements were completed on February 27th and 28th. Immediately following this activity, a Request for Comments (RFC) process was started.
