Minutes

Minutes/Conclusions Reached:

1. Status: PSS still not approved. Asking MnM for participation
2. Additions suggested for Glossary page: modifier, post-coordinated
3. Principles - topics
   1. We need to define what the effect of these principles should be. Perhaps we should convert them into conformance statements and ballot them.
4. Principles
   1. OK. CQI may be responsible for how to handle these "empty query" negations, but we should at least stipulate that they not be recorded in a way that might be confused with actual negation.
   2. OK.
   3. OK
   4. Perhaps this should support different levels of conformance.
   5. Add here a preference to use the term "negation" advisedly, and to distinguish domain semantics where possible. (I.e., where not designing DL rules, as in SCT TIG.)
