On Consolidation

• Procedures for identifying and resolving synonyms

• "Synonym" implies a dictionary analysis, but it may be more useful to think of this in terms of "equivalence classes" - what things are treated as the same or interoperable may be a larger set than just "synonyms"

• Naming rules?

  • Significant variation in how you organized your consolidation tables; seems to suggest different tactics for naming and "proto-aggregation"

  • Does a controlled vocabulary emerge as the driver for or as a result of consolidation?

• Deciding on what components are essential

Plan for the Last Two Weeks

• Some syllabus surgery (and simplification)

• Three lectures on "model-based implementation"

• Introduction to some potentially useful platforms

• Work on your projects!
