SECM Part 2 - Kernel Base Concepts: presented to WG on 3/18/15

Refer to posted slides

Agreements

• Starting principles
• Base concepts (refer to discussion/issues below)
• Concepts will be elaborated with definition, properties, and constraints as appropriate
  • present kernel concepts before adding the detail

Discussion/Issues

• Model
  • Do we need a separate element for model, or is Container sufficient
    • Motivation
      • Designate the model as top level and not have an owner
      • Designate the purpose and scope of the model
      • Model is conceptually a broader concept than a container (per Laura)
    • Candidate Approaches
      • Add a boolean property called isTopLevel
    • Follow-up by reviewing UML concept of model
• ValueSpecification
  • Clarify default value, value spec vs instance spec, slots
  • Determine what is the scope of quantitative values (e.g. time varying, vectors, probability distributions, lifecycle, variants, …)
  • Consider renaming default as baseline per John W and ValueSpec as ValueSet per Ri
• Relationships
  • Include directed only or include undirected
  • Should binary only or include nary

Follow-up

• Capture discussion and issues on Wiki
• Maintain list of issues in spreadsheet until JIRA is up and running
• Discussion follow-up on model
• Discussion follow-up on values
• Schedule next telecon

Next Meetings

• Reston face to face
  • Status and plans for the SECM development
  • Side session on value discussion and possibly model discussion
• Next telecon March 31,
  • Part 3 - Kernel Extended Concepts
