GEON Portal Middleware Finds Use in the Digital Archeological Record Project
GEON portal-based services and middleware framework are being deployed in support of the Digital Archeological Record project (tDAR), led by Prof. Keith Kintigh at Arizona State University. With support from two National Science Foundation grants, tDAR is a project that has brought together a team of ASU archaeologists and computer scientists to design and build a digital information infrastructure (cyberinfrastructure) for systematically collected archaeological data.
Dr. Kai Lin, architect of GEON’s semantic data technologies was invited to participate in an NSF-sponsored workshop, The Promise and Challenge of Archaeological Data Integration, in Santa Barbara at the end of 2004. Workshop participants recognized that the technologies developed in GEON for semantic tagging and integration of data could be adapted and extended for applications in archaeology. When NSF funded the Digital Archeological Record project, Prof. Kintigh and his team approached GEON and proposed a collaboration where the tDAR project could leverage GEON cyberinfrastructure while, in turn, GEON would benefit from new ontology and data integration tools being developed for tDAR.
Kintigh says “This represents an ideal sort of collaboration. Adopting the GEON code base is allowing tDAR to become operational much more quickly and permits us to focus our development on the challenging issues of integrating and preserving legacy datasets with inconsistent data recording protocols and incommensurate ontologies. In turn, we believe that our work can help extend GEON’s capabilities for semantic data processing and data preservation, thus enabling GEON to more effectively utilize legacy data in geosciences and other fields.”
The “look and feel” of the GEON portal are being customized to serve the tDAR community. The GEON portal middleware includes the “GEON software stack” and a set of tools deployed as portlets within the portal framework. The Portal Server runs the Rocks cluster management software, and hosts the GEON Portal and its dependent libraries and portlets. A separate Data Server provides the capability to host data registered through the portal. The Data Server also runs the SDSC Storage Resource Broker (SRB) software, which provides a number of built-in data management services. Uniform authentication within this environment is provided by the Grid Authentication Management Architecture (GAMA) framework. The tDAR portal and data servers are hosted at SDSC.

A separate code repository has been established for the tDAR project to enable concurrent development of software between the two projects. This allows new functionality developed in tDAR to be integrated into the main GEON code base as needed, after software testing and quality assurance.

GEON PIs Professor Ann Gates (Chair, Computer Science, UTEP) and Dr. Chaitan Baru (San Diego Supercomputer Center) will co-chair a panel discussion entitled “Cyberinfrastructure: Changing the Face of Science and Engineering,” at the SACNAS (Society for the Advancement of Chicanos and Native Americans in Science) Annual Meeting, October 11-14, 2007, in Kansas City, MO. This session will provide participants a forum to learn about and discuss state-of-the-art cyber-resources that support education as well as science and engineering research. Topics will include how cyberinfrastructure (CI) removes barriers (e.g., time, space, location, institution) and enables broader participation in science and engineering. Opportunities for involvement in CI efforts and training will also be discussed.
GEON will be present, in a variety of ways, at the upcoming Geological Society of America Fall meeting in Denver, October 28-31. Plan to visit the GEON booth (#136 in the Exhibitor’s Hall) to learn about our latest tools and services and portal enhancements, and to discuss these with project members who have been integrally involved in their development.
A project led by a group of University of Missouri-Columbia researchers has been awarded $2.16 million from the National Science Foundation (NSF) to bolster the collaborative efforts between the U.S. and China in determining the cause of intraplate earthquakes that have occurred in both countries.
