IMLS NLG Program Institute of Museum and Library Services (IMLS)
U.S. Federal grant-making agency, est. 1996 Goal to foster leadership, innovation, lifetime
learning $244 million annual budget
IMLS National Leadership Grant Program Currently about $20 million per year Library, Museum, & Library-Museum Collaborations Funds research & demonstration, digitization,
Four General Recommendations to IMLS:1. Digital collections built with support of public funds can and
should be held to standards that support interoperability, reusability, and persistence.
2. IMLS should maintain its own registry of funded digital collections.
3. Because so much of the IMLS constituency consists of small and medium-sized organizations without sophisticated in-house technical support, the IMLS should also consider projects to develop infrastructure services that lower barriers to NSDL contribution by smaller organizations.
4. IMLS should encourage the integration of an archiving component into every project plan by requiring a description of how data will be preserved.
Prior Work – Mellon OAI Grants July 2001, Andrew W. Mellon Foundation awarded
7 grants for OAI-related research ($1.5 mil. total) Primary focus: demonstrate utility of OAI metadata
harvesting in context of scholarly inquiry Research Library Group (RLG)

OAI Static Repository Gateways SR Gateways support CGI extended path SR Gateways typically cache static repository XML files SR Gateway lists all SRs available through gateway in
<friends> element (dynamic discovery of SRs) SR Gateways assumed to support automated
self-registration of SRs SRs should make themselves available through a
single SR Gateway SR Gateway applications available on SourceForge.net
Working with Turnkey Solutions OAI provider service now built into many popular
digital library applications ContentDM, Encompass, DLXS, DSpace, EPrints.org Facilitates participation in OAI-PMH metadata sharing
Some implementations may be limited Many support oai_dc metadata schema only May have limited feature set (e.g, no resumptionToken) Metadata mappings may not be configurable

Or describe the analog object?Excerpt of record describing Am. woven
coverlet
Description: Materials: Textile--Multi, Pigment—Dye; Manufacturing Process: Weaving--Hand, Spinning, Dyeing, Hand-loomed blue wool and white linen coverlet, worked in overshot weave in plain geometric variant of a checkerboard pattern.Coverlet is constructed from finely spun, indigo-dyed wool and undyed linen, woven with considerable skill. Although the pattern is simpler, the overall craftsmanship is higher than 1934.01.0094A. - D. Schrishuhn, 11/19/99 This coverlet is an example of early "overshot" weaving construction, probably dating to the 1820's and is not attributable to any particular weaver. -- Georgette Meredith, 10/9/1973

Portal Design Issues How best to organize aggregated metadata for
browse Need scalable ways to build / implement classifications Need better methods for clustering and grouping Utilize relationships & ties to collection descriptions
How best to implement basic & advanced searching Precise searching hard due to metadata usage variations Limited normalization possible; more work needed Robust search & ranking across large aggregations hard
Need more audience-specific designs Need more dynamic & interactive designs Need better support of educational & instructional uses
