• Asymmetric Relation is a bit of a puzzle. It doesn't make sense mathematically. Ordered Tuples as represented in graphs doesn't have a source and target. A vector is an operation on a Tuples. Lisp has an operation which returns a beginning and the rest which is how you distinguish the role of members in the Tuples. Other languages don't work like Lisp and have different operations. Like a linked list or doubly linked list.

• may be way accomplish this in a simpler way.
• What Dan said: when we model patterns and kind of do more process stuff and less methodology things we want to think about the temporality of things we want to things about things that go back and forth (from a study or a measure, then changing as we learn more and execute it, when we become interested in execution and what happens during it, and then when we refocus on dispersal, use, understanding, replication and platform independent being human readable, platform dependent being actionable/executable.
• Distinction between algorithm and process. Went round and round and maybe no distinction. If you describe a coding operation and the algorithm but in doing it you used a black box procedure in a specific software.
• The example that comes up in a statistics class in determining error
• Realization: If you want to describe the actual execution you're stuck with binary relations because you need to talk about the interfaces between steps. But do we need that everywhere for everything? Can we describe things that are not so entangled in a simpler way such as the flow of a questionnaire. We have to know at what point we need the binary relations.
• We'll pull this together now on the issue and ask for Flavio's reaction. Then nail down during Sprint. (use DMT-116) Underlying model of DDI 4.

Sprint prep:

• What gets addressed?
• What outcomes are required?
• What do we need to do in preparation?
