 		 PRELIMINARY CALL FOR POSITION PAPERS

	     International Workshop on an Infrastructure 
                       for Temporal Databases

			   Arlington, Texas
			   June 14-16,1993

Most database applications utilize time-varying information, yet
conventional database management systems offer inadequate support
for the processing of such information.  Over the past decade
there has been growing awareness among researchers of the importance
of recording historical information in a database, as well as an
expanded body of knowledge on how to model, store and query temporal
information. The objective of this workshop is to define and
establish a common infrastructure of the discipline and to develop
a consensus base document that will provide a foundation for
implementation and standardization as well as for further research.
  
The workshop will offer the opportunity to identify and define
fundamental concepts and techniques for incorporating time in
databases.  The topics that will be addressed include:

-  requirements for temporal database applications

-  semantics of time-varying information

-  conceptual and physical data models

-  query languages, including extensions to SQL

-  interaction of infrastructure and DBMS architectures

-  implementation issues that will affect infrastructure definitions,
   such as storage, access methods, transaction processing,
   query processing and distribution

-  products, prototypes and standardization efforts

The result of the workshop is to be a consensus report
establishing an infrastructure supporting both desirable practice and
future research.  The format will be designed to encourage productive
interaction among participants.  Therefore, the number of attendees
will be restricted to 40. Lodging, meal and travel expenses will be
paid by the workshop, for which funding is being sought from
DARPA-SISTO, NSF, and CEC.

Invitations will be based on the ability to contribute to a definition
of a widely acceptable infrastructure. Authors are invited to submit
position papers proposing a portion of the infrastructure that they
feel is amenable to consensus. Copies of the accepted papers will be
distributed at the workshop.

Position papers should be between 10 and 25 pages in length, and
should include the title, author(s), authors' affiliation and an
abstract. Submitted papers must indicate clearly
how the work is relevant to the workshop's scope. Submitters should
also indicate their willingness to contribute to the final report.
Ten copies of the manuscript should be submitted by Friday, January
22, 1993 to:

			  Richard Snodgrass
		    Department of Computer Science
			University of Arizona
			 Tucson, AZ 85721 USA
			  [email-masked]
			    (602) 621-6370

We encourage submission of papers from both the academic and industrial
spheres.

			   Important Dates

Paper submission deadline:	January 22, 1993
Notification of invitation:	April 7, 1993
Final copies for distribution 
to participants due:            May 7, 1993
Workshop:			June 14-16, 1993
