The DAVIC Workplan
DAVIC publishes its specifications in versions. DAVIC 1.x
Specifications were published as follows:
DAVIC 1.3 in September 1997
DAVIC 1.4 in June 1998
DAVIC 1.5 in April 1999
The subsequent DAVIC Specifications will cover
the accepted/approved contributions relevant to the call for
proposals issued in the meantime: CFP11, CFP12, CFP13, CFP14
DAVIC 1.0 is organised in 11 parts. These can be classified in
three groups. Parts in Group 1 identify all the tools that are
necessary to build DAVIC-conforming systems. Parts in group 2
describe how the three main DAVIC subsystems can be assembled
using the tools of group 1. Parts in group 3 address system-wide
issues.
