1	Uses and Tools David A. Greenbaum Director, Interactive University Project University of California, Berkeley Digital Library Federation Forum April 21, 2004
2	Use Case Working Group Members: Nancy Hobelheinrich, Stanford University Jay Fern, Indiana University David Greenbaum, UC Berkeley Different perspectives: Digital Library, LMS/E-Portfolio, Content for the Public
3	Began with Use Cases Faculty and graduate students create lecture materials from collections of digital images and associate with syllabus inside campus CMS Faculty and/or graduate students create reading lists from within a Library portal and publish to an independent course web site Students gather class presentation materials for use in e-portfolio tools Students gather images, text, citations from multiple sources to develop a joint presentation for class Library curator creates a themed collection of learning materials based on her subject specialty and publishes it to Library's Subject Resources web page for use by wide range of scholars
4	Functional Abstraction Stepped back from use cases and looked at strategic assumptions. We developed a functional flow, which can be organized into three major areas: Gather. Create. Share.
5	Gather. DISCOVER = identify content sources SEARCH = find content within sources COLLECT = bookmark/link within each content source or within tool, probably using set formats or templates for types of learning objects or aggregations of content IMPORT = into tool or managed environment, bring or point to content itself, or metadata about content . SAVE = prior to publishing, make a copy for the desktop, external or non-personal workspace that is managed for collaboration or sharing FIND SIMILAR = identify like items, per the Amazon.com model
6	Create. DESCRIBE RESOURCE = annotate, interpret, and write about content before publishing ORGANIZE = order, sequence, transform content to create learning object ASSOCIATE = declare link between content or learning object and course, project group or learning objective MODIFY = change, edit, annotate content or learning object for re-use after initial publishing. Differentiated from Organize in that this function may trigger other services to selected community members such as Alerts or Notification related to allowable permissions or conditions to re-use
7	Share. EXPORT = transfer content to other formats and/or tools, e.g., PowerPoint, METS. Differs from Save by its facilitation of supported format, output, packaging of content or learning object for specific display, rendering, use, storage environments PUBLISH = make formally available to learning environment with implications for declaration / agreements related to rights for re-use, short and long term storage and archiving services, and expectations for content transformation services ARCHIVE = establish agreements regarding short or long term storage, preservation, and delivery services.
8	Gather-Create-Share Tools An important problem and product space in building tools and services to support these functions! We do not have any (mature) tools to do this now, although tools are beginning to appear and interest in this problem space is growing.

11	Demonstration Projects: Follow Workflow and Content Life Cycle Users and user experience as driver à Material / Object Type à Sources / Repository technologies à Instantiations of “Gather-Create-Share” tool à Interoperation with other educational and information technologies à Publishing to Learning Object / Digital Repositories à cycle begins anew
12	Other Possible Ways to Build Gather-Create-Share Services Digital Library Service Framework Sakai Chandler Browser Extension Office Suite Others
13	A few questions to think about in tool development Many higher education institutions Sustainable Open Source Extensible … interoperate with multiple repositories, tools, and environments Campus only or does this serve the public as well
14	Final Thoughts on G-C-S This is a use and a reuse exploration We need to explore with real tools and users Where do users start from and where do recombinant content products end up? New type of product: between collections and learning objects = Learning Collections Need to investigate this across digital library, educational technology, and alpha geek cultures Important moment to work together to carry out a series of demonstration projects
