The NIST Identifier Collaboration Service (NICS) is a proposed service to encourage collaboration among researchers and developers when choosing identifiers, far in advance of when it might ordinarily occur. This would support and enhance standards development activities, and development and communications in a variety of fields from software development to system administration. Implementation of this system would provide immediate and significant time and cost-savings to many technology administrators, researchers, developers, and implementors world-wide. This paper describes the benefits of NICS to the Tcl community. This paper also briefly describes the implementation of NICS which Tcl-based internally.
