3. Multi-dimensional time
Best Estimate
Only a subset of product RUNxOFFSET is available:
Number of OFFSETs in particular RUN may vary
Higher OFFSETs in the same RUN may have coarser step
For one Constant Validity Time multiple different forecasts are available
Rapid updates (even hourly or tens of minutes)
Constant Forecast Offset
Constant Valid Time
This issue arises in O&M

5. Summary of WMS Time options
A1. Single layer for all ‘Runs’
based on existing WCS implementations, but to be fully correct it requires more detailed description of dimensions (dependencies). It allows unification all access semantics (TIME, RUN&TIME, Best Run, Best Forecast).
A2. Separate ‘Runs’ into layers or services
based on some existing implementations (treating different model runs as different service end-points). Increases complexity of requests due to external catalogue use.
A3. Separate ‘Runs’ into layer hierarchy
theoretical at this stage, using hierarchical ‘sub-layers’, but creative approach. In principle, similar to A2 but avoiding the need of catalogues.
Key factor of WMO WIS catalogue refresh/harvesting policy

Motion template
Sample Motion:
The <DWG or SWG name> recommends that the OGC Technical Committee approve release of <OGC Document Number> “<OGC Document Name>” as an OGC <Discussion/Best Practices/Engineering Report> Document
Pending and final edits and review by OGC staff
<Any Discussion Points that the TC needs to be aware of>
Motion: <Name of person making the motion>
Second: <name of the person seconding the motion>
If there is a hand vote, the results of the vote. Otherwise, the phrase <There was no objection to unanimous consent> should be used
