FINAL 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 temporal 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 structures, access methods, transaction processing,
   query processing and distribution 
-- products, prototypes and standardization efforts

The result of the workshop will 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 30.
We expect that lodging, meal, and travel expenses for participants to be
partially subsidized by the workshop, for which funding is being sought
from DARPA-SISTO and NSF. 

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 {bf Friday, January 22, 1993} to:

  Richard Snodgrass
  Department of Computer Science 
  University of Arizona 
  Tucson, AZ 85721 USA 
  rts@cs.arizona.edu
  (602) 621-6370 

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