* Use case 1.1: Simple Survey + ConceptualInstrument |
Jay's Breakthrough:
This morning's diagram:
What is A? A is conceptual/ logical What is B? B is the implemented one But what are the relationships between A, B and Instrument Component?
|
Use case – connect questions and statements as a grouped item. Reuse questions which need the associated statements etc 1: Capture could have a relationship to statement and to instruction indicating that these are components that should be used together. The example for this is question bank 2 (Current): There is no direct relationship between Question and statement. You have to go to the instrument Component to see the relationship. Instrument component is a container related to process model which gives you the sequencing. Instrument component is recursive.
Note instrument component is not correct it should be composition Parking lot: Do we have only statement? Or do we need to add in external objects?

What to do with Instructions?? Does it relate to Statement or Act? It is an object which related to Act. Question has a property of text. Use cases Survey example - Dagstuhl evaluation questionnaire Note need to make sure our definitions are tight enough to give guidance to users on how to use objects appropriately

Jay showed the process model to the group to begin thinking about how process model links in with instrument model. We looked at simple process in Drupal. In 3.2 there is something called instrument control. In the process model it was called Act. Jay: What happens to the instrument control? Do you pull in the control construct set of objects? Logical instrument is the design of the data capture. It should point to the process model. It needs to be nailed down a bit. more. Would assume label, description etc in included. The GSIM questionnaire specification had useful text. This has a relationship with control construct (0..n) Control Construct has subtype of Act and Capture is a subtype of Act. Act has a relationship to Statement. Statement is explanatory text etc. Need to set the scope Capture has question and measure. Question is survey specific, Measurement is the more generic Capture has response domain. Instrument control defines how to administer the questionnaire. The sequencing and loops reside in process (in control construct). Use elements of process when it is needed. But can this handle the complicated use cases - example of blood pressure cuff. THIS IS CONTROL CONSTRUCT Value Domain links to Response Domain Parking lot - relationship to Conceptual objects, Question block Next step is to start putting examples against this version of model.
