NASA
- CASI Digital Library Extension through OAI
|
|
In
cooperation with LaRc (NASA Langley Research Center),
the ODU digital Library Group is developing the
infrastructure to allow NASA to maintain a mirror
system and monitoring tools for NASA's unlimited and
unclassified information portion of the CASI STI
database system with the use of OAI-PMH.
Funded
by Langley
Research Center

Cross-Language Federated Digital Library
|
|
|
To federate collections with varying degrees of metadata richness across continents poses a number of challenging issues including how to federate collections
in different languages. The focus of this work is on how to integrate an existing cross-language technique based on query translation into
Arc to support searches across English and German collections. For technical details, please refer to "Cross Language Federated Digital Library Technical Paper".

RAPID
VISUAL OAI TOOL
|
|
Rapid
Visual OAI Tool (RVOT) allows the user to graphically construct a
mapping from a native format (currently supported are RFC1807, Marc
subset & COSATI) to oai_dc format and to create an OAI-PMH-compliant
repository. The tool is self-contained; it comes with a lightweight http
server and OAI-PMH request handler and is written in Java and is
available for download at http://rvot.sourceforge.net . |

DOG(Dienst/Open Archive Gateway)
|
 |
Though the Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) is becoming the defacto standard for digital libraries, some of its predecessors are still in use. Although a
limited number of Dienst repositories continue to be populated, others are precariously unsupported. The Dienst Open Archive Gateway (DOG) is
a gateway between the OAI-PMH and the Dienst (version 4.1) protocol. DOG allows OAI-PMH harvesters to extract metadata records (in RFC-1807 or Dublin Core) from Dienst servers.

The
Technical Report Interchange project is a cooperative
experimental effort between NASA Langley Research
Center, Los Alamos National Laboratory, Air Force
Research Laboratory, Sandia National Laboratory and
Old Dominion University to allow for the integration
of technical reports. This is accomplished using OAI
and having each site cache the metadata from the other
participating sites.

COMOPT
|
 |
In
this project, we are building DL-COTF, an XML based
digital library that we are developing for the Navy's
test and operational needs. COMOPTEVOR, an organization
within the Navy, has as one of its tasks the monitoring
of weapon programs. For each program a large number of
documents in various formats need to be made available
electronically for workflow processing, dissemination,
discovery, and preservation ( COMOPTEVFOR
Digital Library ). |

DSpace
|
|
Dspace is a digital library system developed jointly by MIT Libraries and Hewlett-Packard HP. The OAI harvester plug-in enables Dspace to harvest metadata and full text from OAI compliant data providers. Once harvested, the records can be retrieved using Dspace standard search interface. |

NCSTRL+
|
|
In
this project we are creating the infrastructure forming an
association of digital libraries within NASA Langley to
support intelligent digital objects and clustering based on
the successful distributed architecture of Networked Computer
Science Technical Reference Library (NCSTRL) . We have
designed and implemented clusters and bucket technologies,
that allow for the integration of multi-discipline and
multi-format NASA Scientific and Technical Information holding
(STI).
Our
core technology test bed is NCSTRL+,
a set of tools and extensions from NCSTRL.
NCSTRL+ implements two significant technologies: clusters
and buckets. Clusters allow for arbitrary combining and
partitioning of collections along axes such as subject
category, archival type, publishing organization and terms and
conditions.

NCSTRL+
ODU testbed : This test bed
consists of various collections and is to be used
for illustration of the search interface only; the
other tools are early versions - go to NCSTRL+
NASA test bed.
NCSTRL+
NASA test bed : This test bed has
only one collection with a few objects but has the
latest set of tools to support the entire life
cycle of digital objects.

sODA
|
|
The
Smart Object, Dumb Archive (SODA) Model is an
architecture for publishing that complements the use of
buckets. The goal is to increase DL interoperability by
pushing down functionality generally associated with
archives into the DL objects themselves. Thus, the
archives become "dumber" and the objects
"smarter".
