The Development of SEDRIS Standards

Role of Standards in Infrastructure Technologies

Having a standard way to accomplish something considered an infrastructure technology serves two very useful roles. First, it frees the user to concentrate on the more important application-level development, since there is no need to devote time and resources to designing the infrastructure. Secondly, it makes it possible for the users to communicate effectively and unambiguously through a standard mechanism. This, in turn, makes interoperability possible.

Another important role of standards, and particularly international standards, is to subject the technology to scrutiny by a wider, more diverse audience. This was the primary reason the SEDRIS Organization elected to pursue the development of international standards.

Finally, there are many in the community who look for the "badge of approval" when it comes to embracing infrastructure technologies such as SEDRIS. This is another reason standardization through ISO/IEC was initiated.


SEDRIS Technologies Standardized Through ISO/IEC and SISO

In October 1999, SEDRIS began the process of establishing international standards through the combined International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). SEDRIS technologies have been assembled into the following specification and language binding standards through the ISO/IEC.

  • SEDRIS
    • Part 1: Functional specification
    • Part 2: Abstract transmittal format
    • Part 3: Transmittal format binary encoding
    .
  • SEDRIS language bindings
    • Part 4: C
    .
  • Environmental Data Coding Specification (EDCS)
  • .
  • Spatial Reference Model (SRM)
  • .
  • EDCS language bindings
    • Part 4: C
    .
  • SRM language bindings
    • Part 4: C

ISO/IEC Joint Technical Committee 1 (Information technology) assigned the standards development work to its SubCommittee 24 (Computer graphics, image processing and environmental data representation) that created a new Working Group 8 (Environmental representation) to be the focal point for SEDRIS standardization.

Establishing formal standards was a key part of the SEDRIS development plan. Pursuing international standardization helped ensure a broad base for applying SEDRIS technologies, and opened interoperability opportunities in multiple national and international markets. However, developing formal specification standards was insufficient to realize all the interoperability potential that SEDRIS could provide. Establishing tested implementations, guidance and education documents, and data coding mapping documents was also required. Toward this end, in the spring of 2000 the Simulation Interoperability Standards Organization (SISO) established two Product Development Groups (PDGs) to address technical implementation of the SRM and EDCS ISO/IEC standards.
