Langley Technical Report Server (LTRS)
http://techreports.larc.nasa.gov/ltrs/
This project grew out of an anonymous FTP server I set up for NASA LaRC in 1992. The WWW version came in 1993. I maintained the service until 1996, and served in an advisory role from 1996-2002.
NASA Technical Report Server (NTRS)
http://techreports.larc.nasa.gov/cgi-bin/NTRS
NTRS grew out of a proliferation of "LTRS-like" nodes. I've always been involved with NTRS, but have had help. David Bianco wrote the first version of the software (1994), and Ming Maa wrote an update (1996). I am working on an OAI-based version is scheduled to go into production in 2002.
NACA Technical Report Server (NACATRS)
http://naca.larc.nasa.gov/
Getting NACA reports online has been a long, strange trip. The project began in 1996, but did not really gain a sufficient number of documents until 1998. Finding all NACA reports and putting them online is probably a lifetime endeavor.
Arc was the first OAI-based service provider for end users. Hussein Suleman had the Repository Explorer prior to Arc, but that is more of a developers' tool than an end-user service. Arc was also the first OAI service to be both a service provider and data provider, allowing for hierarchical harvesting. Xiaoming Liu did most of the coding and design for Arc.
NCSTRL
http://www.ncstrl.org/
This is the OAI-based version of NCSTRL. The OAI version replaced the Dienst version in late 2001. This work was joint with Va Tech & UVa. The interface and engine is based on Arc.
Archon
http://archon.cs.odu.edu/
This NSF-funded work is joint with LANL and APS. Southampton and CERN are also contributors. Its focus is value added searching for physics metadata. It is OAI-based, and exeperiments with reference linking and equation-based searching.
Technical Report Interchange (TRI)
This work is joint with LANL, AFRL, Sandia and NASA. It is focused on allowing ingestion and exporting of metadata from native digital libraries using synchronized caches. There is no public page for this work yet.
Kepler
http://kepler.cs.odu.edu/
This NSF-funded work is joint with LANL, USGC and UPenn. It is based on developing small OAI-based applications that allow individual users to become OAI data providers.
Open Video Project
http://www.open-video.org/
Gary Geisler & Gary Marchionini are responsbile for Open Video. While at UNC, I experimented with some bucket-based storage and interfaces to the videos. I also developed an OAI data provider interface for them. Terry Harrison did the conversion to OAI 2.0.
