1. The refset will have a stated inclusion criterion, exclusion criterion, and purpose (which as whole is the definition). The definition includes examples that are part of the refset, as well as boundary cases that should not be part of the refset.
2. The stated definition, inclusion criterion, exclusion criterion, and boundary cases must be understandable, reproducible, and useful, in that at least two independent modelers can review the contents of the refset, and agree on the inclusion of concepts, and exclusion of related concepts (siblings and lexically similar terms). If URU is not achieved, then the stated definition, inclusion criterion, exclusion criterion, purpose, and boundary cases that should not be part of the refset needs to be revised until URU is achieved.
3. The refset contains all the members from the spreadsheet.
Changed name of refset and the "anchor" concept in the metadata hierarchy.
Will need to discuss adding "foreign body" to this refset; we probably need a physical object; what is available now is a finding and a morphology foreign body.
Added Foreign body (morphologic abnormality) to refset.
Please add nursing dialect term of prosthesis for prosthesis, device.
"Prosthesis" added to nursing dialect
