Geoff Collier & Robby Robson, Editors In this Issue: June 2002 E-learning Calendar - E-learning events happening in the month of June. The CommonPlace - A Place for E-learning - The CommonPlace web site is up. So what? CanCore Puts Meta-data into Practice – CanCore has developed a set of guidelines for using meta-data to catalog, discover and share educational objects, built on the IMS Meta-data specification. Making Meta-data Practical – Now that meta-data standards are available, how do you make use of them in the real world? This article points to guidelines and existing implementations. Taking Advantage of RDF - A recent workshop showed how RDF can be used to combine multiple catalog records into a single, richer record. Links to RDF tools are also provided.

News and Views News and Views Issue 3 May 17, 2002 The CommonPlace - A Place for E-learning The CommonPlace web site (www.theCommonPlace.net) became available April 30, 2002. The CommonPlace is a place to exchange information, ask questions, and find people and resources. The Commonplace is free for all to use. Its future depends on participants for input, direction, and content. To get things started, there are three forums on the site (www.theCommonPlace.net/forum): Real world examples of e-learning standards in use- Come to this forum to share information on your implementation of e-learning standards, and to ask what others are doing. Working e-learning products and reference sites - This forum is the place to share and find information about e-learning products and working implementations. News and Views - On this forum, criticize or praise the articles, provide your thoughts on e-learning, or discuss the implications of the information in the articles. These initial forums were based on suggestions from the News and Views audience. You can use the web site to suggest others. There is just a small amount of content on The CommonPlace consisting of back articles and references from News and Views, and some links to e-learning sites. Please feel free to suggest other material or sites. The CommonPlace is a place to find and communicate with those who create, acquire or implement e-learning technology. It will evolve in response to your participation and your input. Developers may want to exchange code or talk about best practice. Consumers might like to see each other’s reviews of products. The CommonPlace welcomes contributions and places no up front restrictions on what suggestions will be considered. “There have been many calls for an open means of communication among the communities of use for e-learning technology." According to Ed Walker of IMS, “The CommonPlace is an experiment to test whether the time for doing so is right. IMS provided initial support for The CommonPlace. If it is used, and other organizations help support it, The CommonPlace will continue to be available to the world-wide community of practice.” Please have a look at www.theCommonPlace.net. Give us your opinion, good or bad. Your feedback will determine what happens on and to The CommonPlace. News and Views News and Views Issue 3 May 17, 2002 CanCore Puts Meta-data into Practice Norm Friesen, Information Architect, CanCore (www.cancore.org) Meta-data allows digital educational resources to be properly cataloged and effectively searched. Putting meta-data into practice, especially for large collections of content, requires clear standards that define the structure of the meta-data elements and the rules for populating these elements when tagging a resource. Global meta-data specifications provided by organizations like IMS and the Dublin Core provide a structure, but do not specify precisely which elements must be populated, nor what values are allowed in these elements. To help address this gap, a group of Canadian educators have been developing guidelines known as CanCore, which are based on a subset of the IMS Meta-data elements. The CanCore guidelines are intended to facilitate the cataloging, discovery and sharing of education resources in Canada and around the world. CanCore has been adopted by a number of repository projects, including POOL/Splash (Portal for Online Objects in Learning - www.edusplash.net), CAREO (Campus Alberta Repository of Educational Objects - www.careo.org) and BELLE/Alexandria (Broadband Enabled Lifelong Learning Environment - www.netera.ca/belle and alexandria.netera.ca). "Like SCORM, we're focusing on the most useful elements for interoperability in IMS Meta-data, but at the same time, we're also documenting best practices for their use." explains Anthony Robert, Manager of Telecampus (telecampus.edu). "This is not a new specification or standard," according to Roberts. "It's an attempt to bridge the gap between the generalities, ambiguities and choices left open by the IMS specification and the particular needs of implementers." The CanCore team includes experts from Athabasca University (Canada's Open University), the Electronic Text Centre at University of New Brunswick, and TeleEducation New Brunswick. Support is being provided by a wide variety of industry, academic, and government organizations, including Alberta Learning and Industry Canada. CanCore is currently releasing draft chapters of its guidelines document for public comment. Each chapter addresses a particular element group in the IMS Meta-data specification, and provides: refinements of definitions; discussions of best practice; vocabulary recommendations and definitions; multiple XML-encoded and plain language examples; and technical implementation notes. Draft guidelines are freely available from the CanCore Website at www.cancore.org. Comments and questions can be directed to Norm Friesen (norm.friesen@ualberta.ca) or Anthony Roberts (aroberts@nbnet.nb.ca). News and Views News and Views Issue 3 May 17, 2002 Making Meta-data Practical Robby Robson, Eduworks Corporation (www.eduworks.com) In August of 2001, key participants from several meta-data initiatives met in Ottawa, Canada, and agreed to a series of steps intended to make it easier to understand and use meta-data. The first of these steps was an article entitled Metadata Principles and Practicalities that has just appeared (www.dlib.org/dlib/april02/weibel/04weibel.html). At the heart of this effort is the interplay between general frameworks for cataloging and finding learning resources and the specific needs of an organization or community. These needs are often served by using multiple meta-data frameworks but also involve developing specific descriptive elements and vocabularies for local use. Expository material, best practice guides, and concrete examples all can help understand how this is done. While Metadata Principles and Practicalities is expository, projects like CanCore (see Norm Friesen's article in this issue) provide best practice guides and examples. More examples of meta-data in action are available from the UK Office for Library and Information Networking (www.ukoln.ac.uk/). Further examples of applied meta-data have been kindly provided by Cisco Systems (www.thecommonplace.net/add/Cisco_metadata_spec.pdf) and the Center for Educational and Training Technology at Mississippi State University (www.thecommonplace.net/add/ICADTaxonomyv1p2-public.pdf). These documents describe how the two organizations use meta-data for their own purposes. Their implementations demonstrate how to create meta-data for local use and how local variants mesh with standardized approaches so that internal requirements and interoperability requirements can be simultaneously addressed. The work launched in Ottawa, projects like CanCore, services provided by organizations like the UK Office for Library and Information Networking, and examples like those provided by Cisco Systems and Mississippi State University are playing a crucial role in making meta-data practical. News and Views News and Views Issue 3 May 17, 2002 Taking Advantage of RDF Liddy Nevile, Director of Motile Research (www.motile.net) At the Museums on the Web 2002 Conference (www.archimuse.com/mw2002), Eric Miller and Ralph Swick conducted a mini-workshop on how museums can take advantage of the World Wide Web Consortium's Resource Description Framework, better known simply as RDF. The slides for their presentation are available at http://www.w3.org/Talks/2002/04/19-rdf/. Part of their presentation involved a demonstration that brought together a variety of catalog records from the Art Museum Image Consortium (AMICO) (www.amico.org) collection in order to provide a richer catalog record. In the demonstration, two records were selected. One was a record that showed an image from the AMICO collection and the meta-data associated to the image by AMICO. The other was a library style record that referred to information about the artist of the original painting. The result was a new record that revealed both sets of information meaningfully combined. For those inclined to try RDF out themselves, several tools are available for authoring and using RDF. Among these are: 1 The Redfoot RDF framework (redfoot.sourceforge.net) provides a system for building distributed data-driven web applications with RDF and Python. It includes an RDF database, query API, template language, module architecture, editor all with web interface, sample applications and the beginnings of Peer To Peer support. 2 The Jena Java RDF API and toolkit (www.hpl.hp.com/semweb) is a comprehensive Java system. Jena contains an API for manipulating RDF models (including statement and resource-centric methods using cascading calls for easy object orientated use), container support, the ARP RDF/XML parser, an RDF/XML writer, the RDQL query language, DAML support, and persistent storage. 3 IsaViz (www.w3.org/2001/11/IsaViz) is a visual authoring tool for browsing and authoring RDF models represented as graphs. IsaViz is based on the Xerox Visual Transformation Machine. Other tools can be accessed from the W3C RDF tools page (www.w3.org/rdf). RDF was designed to enable Web resources to be linked in ways based on meaning, not just location. The AMICO demonstration shows that RDF makes it is possible to sensibly combine two descriptions of the same object. This could be crucial in situations where learning objects have multiple meta-data records because they are used and cataloged in multiple ways from multiple perspectives. News and Views
