The text version of the Sedris Quiz!
Keeping with the SEDRIS Special Issue theme, the quiz column is focusing on SEDRIS. The answers to all of the questions can be obtained by reading the SEDRIS articles in this issue (hint, hint). As there will be an election regarding the development of SEDRIS standards, this quiz will enable you to determine how well you understand the issues that you may be voting on. Enjoy the column, and good luck! Also, check out the "Who Wants to be a Millionaire" version. Questions or comments are welcome and should be e-mailed to sheldon@magicnet.net. Finally, a special thanks to the following individuals for their contributions!

b. SEDRIS Transmittal Format (STF)
c. the Terrain Data Coding Specification (TDCS)
d. the SEDRIS interface specification (API)
Answer
Question 2: Which of the following statements is not true regarding the Environmental Data Coding Specification (EDCS)?
a. EDCS is designed such that it can be utilized independently of the SEDRIS Data Representation Model (SDRM).
b. The EDCS conventions for ocean, atmosphere, and space domains are based on the classification and attribute codes from the standards of those domains.
c. The EDCS convention has been designed to enable the inclusion of additional codes.
d. The EDCS provides for conventions in classifying objects, while allowing the individual developer to include his own convention for describing object attributes.
