In the SAGE project, we used DL expressions to define post-coordinated terminology codes. The information model remains fixed. Complex description of patient states are, in effect, handled in terminology. How do you plan to deal with the open-world-assumption problem? If an eligibility criterion says the patient should not be taken certain drug, do you have to write closure axioms for every patient?
