NSDL 2. 0: Creating a Collaborative Digital Library Dean Krafft, Cornell University dean@cs. cornell. edu
What is NSDL? § An NSF-funded $20 million/year program in Science, Technology, Engineering and Mathematics (STEM) education § A digital library describing over two million carefully selected online STEM resources from well over 125 collections (at http: //nsdl. org) § A core integration team (Cornell, UCAR, Columbia) working with 10 “Pathways” partners and over 200 NSF grantees § A large community of researchers, librarians, content providers, professional societies, developers, students, and teachers

Organizational Evolution § Clear specialization and roles for Core Integration institutions § Tight partnerships with Pathways based on Memo of Understanding § Focused program of collaboration with professional societies and other organizations § Strong educational outreach and focus on professional development
NSDL Pathways Partners § Educational level and discipline specific views of NSDL § Built by leading organizations who are trusted by their target audiences § Provide resources, tools, services, and professional development § A method for professional organizations to engage and serve their membership communities

Partnership Metrics § Number of NSDL Program grantees: 235 grants to 34 states totalling approximately $137. 4 million § Number of Pathways: 10 § Number of partner organizations within Pathways: 85 § Number of members of professional groups within Pathways: Over 1. 2 million
Strategic Partnerships § Library building and awareness building have created a critical mass of value that enables new kinds of partnerships § We no longer expect that users will primarily reach NSDL through nsdl. org § NSDL is creating the socio-technical middleware to bridge research and education communities: ‣ Brokering, facilitation, translation ‣ “Business to business” services and tools ‣ Organizational and technical consulting and codevelopment
Oversight and Guidance § National Visiting Committee - chaired by Diana Oblinger, Educause § NSDL Best Practices: developed by committees nominated by CI/Pathways PIs, voted on by PIs § Policy Committee - represents broader constituency of NSF-funded NSDL grantees
Technical Evolution § NSDL has transitioned from a metadata record database (union catalog) to a digital object repository based on Fedora § NSDL is now a platform of interacting web services and applications § Contributing to NSDL: in addition to heavy-weight OAI server, we now support many light-weight services and applications
NSDL’s Technical Vision § NSDL 2. 0 as a platform for developing digital library tools § Support for communities across the full range of science, technology, engineering and mathematics research, learning and education § The library as a shared, collaborative, contributory space § Supporting the creation of context around library resources to enhance discovery, use, and understanding

In Architectural terms, we created an NSDL Data Repository that § Supports storing both content and metadata § Allows arbitrary relationships among resource and metadata objects: organization, annotation, citation § Accessible through web service architecture of remixable data sources and transformations
NSDL: The Production Library § NSDL Data Repository (NDR) implemented using Fedora 2. 2 with Proai, MPTStore, and journalling § Primary resources are aggregated using OAI from 130 collections § Proai serves normalized NSDL_DC § MPTStore supports RDF relationships among agents, metadata, resources § Journalling: 3 replicated production repositories
NSDL Data Repository (NDR) § References to over 2 million selected STEM resources on the web and in NSDL web applications § Sourced metadata statements about those resources § Annotation relationships among resources § 4. 7 million digital objects and 250 million RDF triples § In production at ndr. nsdl. org
NSDL Service-Oriented Architecture § NDR API provides authenticated access to the repository - Expert Voices (EV), NCS § Search service REST API supports programmatic search - Pathways, Strand Maps § OAI-PMH ingest and server allow batch aggregation and dissemination - all collections, search § Shibboleth Community Sign-On for user authentication - EV, nsdl. org, Engr Pathway, . . . § SDSC Archive - REST access to archived resources - SERC, nsdl. org § RSS feeds - NSDL editorial content, EV
Collaboration, context, and contribution § The NDR and services provide the platform, but we still need the applications § Solution 1: Leverage the existing successful models: blogs, wikis, bookmarking/tagging § Solution 2: Leverage the existing software: Word. Press, Media. Wiki, Connotea, Sakai § Solution 3: Engage with partners and the broader community to build applications to the platform: adapting the DLESE Collection System; integrating Instructional Architect
Expert Voices § The NSDL Blogosphere, live at http: //expertvoices. nsdl. org § Topic-based discussions (e. g. forensics) linked to related library resources § An outreach tool to explain and document NSF -funded research § A way for NSDL community members to become NSDL contributors: of resources, questions, reviews, annotations, metadata § A question/answer and discussion forum: scientist ↔ teacher ↔ student ↔ librarian

Expert Voices Implementation § Wordpress-based multi-user multi-blog application (open source, plug-in architecture) § Published entries become NSDL resources § Editor controls publication of entries and visibility of comments § Entries can contain linked references to NSDL resources, references to URLs that should become resources, and new resource metadata § Integrated with NSDL Shibboleth-based community sign-on (Wordpress plug-in) § Blog(s) available as RSS feed(s)
Our. NSDL: NDR-integrated Wiki § Community of approved contributors (e. g. teachers, librarians, scientists) are granted edit access on Our. NSDL wiki § New resources and metadata are created as wiki pages and reflected into the NDR § Non-wiki-based NDR resources and metadata are displayed as read-only wiki pages, subject to comment and linking § User and project pages organize NDR resources § Now implementing Media. Wiki extensions
My. NSDL: NDR-integrated tagging, bookmarking, and recommendation § Based on Connotea open-source folksonomic tagging/bookmarking system § Tags and bookmarking structure are reflected back into the NDR § Authorized users can “automatically” recommend new NSDL resources simply by tagging them § Gives user a personal view of NSDL resources § Currently in the planning phase
NSDL Concept Map Tool § Implementation of AAAS concept maps and benchmarks from Atlas of Science Literacy § Part of an ongoing effort to relate NSDL resources to educational standards and benchmarks § Beta version live now at http: //strandmaps. nsdl. org
NSDL Collection System § Developed by DLESE from DCS § Allows creation and editing of collection and item metadata records § Extensive guidance and help for various categories of metadata § Syncs records using the NDR API § First prototype developed § Released version expected 2 Q 07
Other planned collaborative tools § Fez/On. Ramp: multi-user, multiproject NDR-integrated CMS § Moodle or Sakai Course Management System: courses integrated with NSDL resources § Instructional Architect: Lesson plan creation for K 12 teachers (Utah State) § Content Assignment Tool: assigning educational standards to resources
Putting NSDL in the path of the user § Goal is getting users to the right NSDL resources, not to nsdl. org § Pathways portals provide discipline specific access § NSDL Toolbar (available at nsdl. org/toolbar) allows direct NSDL Pathways/resource access from user’s browser
Search Engine Landing Page § Landing pages are available to web search engines through sitemap files § Provide information on the NSDL context of the resource, including metadata, annotations, related resources § “Selected by NSDL” resource page logo will link back to this page
Release Timeline § Now: NDR, resource-centric search, public NDR API, Expert Voices public beta, Concept Maps public beta, toolbar § May: Our. NSDL public beta, Sitemaps/landing page § 2 Q 07: NSDL Collection System § Later in 2007: My. NSDL, Fez/On. Ramp, Moodle/Sakai integration, production releases of EV, Concept Maps, Our. NSDL
NSDL 2. 0 Ecosystem Archive Service STEM Collections Search Service Fedorabased NDR … Protocol: OAI-PMH HTTP REST NDR API
A publicly available platform § Initial repository and tools targeted at Pathways and STEM education § Tools and systems open source, or extensions to existing open source § Could eventually release “shrinkwrap” NDR and tool sets § NSDL 2. 0 is an open-source open repository, and creates an open environment for contribution, collaboration, and social networking
