RELEASE DATE:  April 1, 2004

NOTICE:  NOT-RR-04-007 

National Center for Research Resources (NCRR)

Attention to applicants responding to 
and PAR-03-134 
This notice is meant to make clear that particular research activities 
related to the formalization of data concepts are appropriate under 
these announcements.

The overall goal of these announcements is to support research and 
development of tools and approaches for computing on data; most of 
these will likely be implemented in software.  Best practices for such 
endeavors include the explicit formalization of data-related concepts 
that pertain directly to the software.  This would include activities 
such as:  1) assessing data flow and use; 2) defining the terms used 
for data, fields, operations, etc.; 3) defining the relationships among 
terms and functions; 4) defining data models and schemas; and 5) other 
similar activities.  It is important to emphasize that these activities 
are appropriate as they relate closely to the particular software, 
itself, or to making the particular software interoperable with other 
specific software or databases.  However, broad efforts at developing 
ontologies and semantic relationships for entire domains or disciplines 
would not be considered an appropriate activity under these 

Applicants with questions should contact either Dr. Michael Huerta 
(, 301-443-3563) or Dr. Gregory Farber 
(, 301-435-0778).
