Agenda

• Proposed:
  • Mon 5 May : Wrap up: conceptual model development
    • Flow
    • Wells
    • INSPIRE compatibility check
  • Tues 6 May: Progress: logical model development (GML/XML)
    • GeosciML link
    • O&M link
    • cardinalities (logical vs conceptual)
    • auto-generate compatibility
  • Wed 7 May am: Progress: logical model development (GML/XML)
    • same as above
  • Wed 7 May pm: Planning: use case implementations, schema development
  • Thurs 8 May am: TBD
  • Fri 9 May: optional for small group work for anyone remaining

Results

• Conceptual Model
  • completed mid-week
    • see GWML2 CM 1.0
  • major revisions:
    • fluid body: added constituent relation
    • groundwater flow: revised interFlow, intraFlow, and water budget
    • wells: revised wells and springs
• Logical Model
  • completed significant portion of first draft at end of week
    • see GWML2 LM 1.0 pdf
  • major items:
    • pattern: identify voidable properties and others
      • voidable properties may not have empty values: explicitly require a null value to indicate empty/unknown
      • non-voidable properties may have empty values
    • Hydrogeological Units, Groundwater Properties
      • pattern: used OM_Measurement for properties requiring soft-typing, uom, and method metadata (how the value was calculated)
        • e.g. gwUnitProperty, gwPermeability, gwPorosity (there are many kinds of permeability, porosity, etc., that can be calculated in various ways)
      • use GeoSciML PhysicalProperties for EarthMaterial properties (not OM_Measurement) to avoid extending GeoSciML
    • Fluid Body
      • use Observations & Measurements to encode water quality constituents, i.e. Material, Chemical, and Biologic
      • then GW_ChemicalConstituent, etc., are features-of-interest for the observation
    • Wells
      • Lithology Logs: use O&M to encode Logs
      • Boreholes and WellConstruction: use GWML1 package
• Use-Case Implementations
  • confirmed participants
  • reviewed and confirmed objectives
  • note: use case 5 well underway with INSPIRE - GWML2 CM 1.0 mapping
• Workplan (aggressive)
  • end May: complete logical model
  • mid June: generate XSD, XML instances
  • early July: compete draft report (contains conceptual model, logical model, XML conformance classes and instances)
  • July: review draft report
  • early Aug: submit draft report to HDWG for feedback at HDWG annual meeting Aug 2014 in NY
