Appendix 3
2003 Services Excluded in 2006 Report


AARLIN: the Australian Academic & Research Library Network
http://www.aarlin.edu.au/
Goal: National Portal Framework
Status: Moved from project phase to an operating system and achieved its goals by December 2004. Continues as a priority with 12 member libraries deploying Ex Libris with Metalib and SFX modules.
Summary of achievements reported on 12/9/2004.
http://www.caul.edu.au/caul-doc/caul20042aarlin.pdf
Strategic directions 2006-07 available from
http://www.aarlin.edu.au/about.shtml
AmericanSouth.org
http://americansouth.org/
Goal: Scholar-designed portal prototype service
Status: Since 2003 has grown from 18 to 31 contributing archives with combined records increasing from 28,775 to 55,371. "Lessons learned" put into practice in new Emory University and DLF projects (see Aquifer affiliated projects in this report, including The Southern Digital Archives Conspectus from Emory).
Documents from Emory's MetaScholar Initiative, including reports about the MetaArchive Project, AmericanSouth, MetaCombine, Music of the Social Change, and proceedings from the Workshop on Applications of Metadata Harvesting in Scholarly Portals: Findings from the MetaScholar Projects: AmericanSouth and MetaArchive (Halbert 2003) are available from http://www.metascholar.org/documents.html.
AmericanSouth Final Project Report submitted to The Andrew W. Mellon Foundation, March 1, 2004: http://www.metascholar.org/pdfs/AmSouth-FINAL-REPORT.pdf
Used as basis for advanced visualization and semantic clustering R&D in the MetaCombine project.
http://www.metacombine.org/
MetaCombine Project Interim Report on experiments in combined searching, automated organization of OAI and Web resources, and new forms of scholarly communication, September 2004.
http://www.metacombine.org/reports/project/
"SouthComb" Project will continue to develop the content, technologies, and practices developed in AmericanSourth.org. (Refer to section 4.4.8)
Archon
http://archon.cs.odu.edu/
Goal: To build a DL that federates Physics collections with varying degrees of metadata richness.
Status: No survey response received.
Most recent presentation available at Web site from 2003 covers Archon's architecture, equation and formulae searching, reference linking, conclusions and future directions. It announces plans:
to make a separate service that can be plugged in or out which will make development changes easier and allow third party development of similar services
to modify reference resolution to be able to refer to documents whether inside or outside the digital library
to make this service context dependent using some of the technologies such as OpenURL to make the resolution dependent on the location and privileges of the user
to work on the secure management of user accounts and access privileges using Shibboleth architecture to enable different access levels depending on use groups such as students or faculty (Digital Library Group, Old Dominion University, ICNEE PPT, available from http://archon.cs.odu.edu/publications.html.
Archon is also discussed in "Lessons Learned with Arc, an OAI-PMH Service Provider" (Liu et al. 2005)
ARL Scholars Portal Project
http://www.arl.org/access/scholarsportal/
Goal: To provide software tools for an academic community to have a single point of access on the Web to find high-quality information resources and, to the greatest extent possible, to deliver the information and related services directly to the user's desktop.
Status: As of May 2004, the project became "self-managing" among participating institutions with functional implementations using Fretwell-Downing software (under 3-year contract) with campus-wide releases at Arizona State University, University of Arizona, Iowa State University, and the University of Utah, and limited releases at University of Southern California (USC), University of California - San Diego (UCSD), and Dartmouth College.
Scholars Portal Project Report, issued by ARL, May 10, 2004
http://www.arl.org/access/scholarsportal/SPupdateMay04.html
See also "The Current State of Portal Applications in ARL Libraries" (Jackson 2004)
http://www.arl.org/access/portal/PAWGfinalrpt.pdf
Cyclades
http://www.ercim.org/cyclades/
Goal: To develop an open collaborative virtual archive service environment supporting both single scholars as well as scholarly communities.
Status: CYCLADES was a R&D project in operation from 1 November 2000 to 31 August 2003,
supported by the IST Programme of the European Commission (project no. IST-2000-25456) and set up under the framework of the DELOS Network of Excellence on Digital Libraries. Refer to:
"An Open Collaborative Virtual Archive Environment" (Straccia and Thanos 2004)
"A Personalized Collaborative Digital Library Environment: A Model and an Application" (Renda and Straccia 2005)
ENC Online: Eisenhower National Clearinghouse for Mathematics and Science Education
http://www.goenc.org/
Goal: Online math and science K-12 resource center.
Status: ENC resources were available free-of-charge until its funding from the U.S. Department of Education funding terminated. Effective October 1, 2005, goENC.com switched to a subscription service at a cost of $349 per school.
Among the ENC projects discussed in the 2003 DLF report, the only post-ENC project still active is the NSDL Middle School Portal, (although previous relics from ENC still show in up in NSDL search results).
NSDL Middle School Portal with Pathways to Mathematics, Science and Technology is available from
http://msteacher.org/
Flashpoint (Los Alamos National Laboratory)
http://lib-www.lanl.gov/lww/flashpoint.htm
Goal: Multi-database search tool for internal use at LANL.
Status: No survey response received. About LANL Research Library's new digital object repository architecture refer to: "aDORe: a Modular, Standards-based Digital Object Repository
" (Van de Sompel et al. 2005).
UIUC Digital Gateway to Cultural Heritage Materials
http://oai.grainger.uiuc.edu/
Goal: OAI aggregator of cultural heritage metadata.
Status: Since 2003 number of collections grew from 25 to 31; records increased from 413,563 to 538,485. However, project is now static and under review for probable discontinuation in light of the new IMLS Digital Collections and Content project, discussed more fully in Section 4.4.2 of this report. "Lessons learned" put into practice in other UIUC & DLF projects.
Publications and presentations from UIUC's OAI metadata harvesting projects available from http://oai.grainger.uiuc.edu/presentations.htm
See also, "Current Developments and Future Trends for the OAI Protocol for Metadata Harvesting" (Shreeves et al. 2005)
IMLS Digital Collections and Content Project
http://imlsdcc.grainger.uiuc.edu/
XTCat
http://alcme.oclc.org/ndltd/SearchbySru.html
Goal: One-time extract of 4.3 million bibliographic records from OCLC's WorldCat.
Status: Dormant. Arc continues to aggregate the entire set of records. OAIster continues to aggregate the 8,255 records that point to full text. The NDLTD Union Catalog includes a regular harvest of ETD metadata from OCLC's WorldCat, as discussed in Section 4.2.6.
