Modeling metadata

• Focus describe SNAP-like simulations
• N-body
• (adaptive) mesh
• evolving objects in 3D space
• Subjects
• Physics, phenomenology (semantics)
• Design and provenance
• Characterisation
• Use
• SNAP service
• Registration

Proposed approach

• Conceptual/analysis model first
• Decide what we want to model
• Model this problem domain in some, but not every
  detail
• No consideration of implementation or efficiency
• Start with listing of concepts ala Semantics
  standard vocabulary (use those results)
• Create logical model that has details filled in
  and is targeted to the actual problem area.
• All in UML !
• Create bindings to relevant languages
• XML schema
• Java, C,
• Relational model (for ADQL)

4
Model areas

• Charecterisation as summary of properties
• What do we characterise ?
• What could we have seen ?
• What did we see ?
• How do we summarise ?
• Physics
• What physical processes
• What objects
• Numerical Algorithm
• What type of simulation
• What parameters
