Return to [[systems_engineering_concept_model_workgroup]] 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 Return to [[systems_engineering_concept_model_workgroup]]
