How To Use This Target

Use native GMEOW terms as the authoring surface, then inspect the projection rows below to see which facts can leave GMEOW for this consumer vocabulary. Treat lossy notes as adoption warnings, not as implementation details.

Loss Notes

Profile	Source	Dropped Structure
`ivoa`	`gmeow:ScalarQuantity`	unit, determinacy, granularity, and reference frame are dropped; only the measured physical quantity survives
`ivoa`	`gmeow:Sensor`	the telescope/facility node is preserved, but agent roles and platform location are dropped
`ivoa`	`gmeow:Sensor`	the instrument node is preserved, but agent roles and platform location are dropped
`ivoa`	`gmeow:SensoryObservation`	determinacy, granularity, standpoint, and reference-frame metadata are dropped; only the generic dataset class survives
`ivoa`	`gmeow:SensoryObservation`	the full GMEOW reference-frame profile is flattened to a coordinate-system string or IRI
`ivoa`	`gmeow:SensoryObservation`	the telescope/facility node is preserved, but agent roles and platform location are dropped
`ivoa`	`gmeow:SensoryObservation`	the instrument node is preserved, but agent roles and platform location are dropped
`ivoa`	`gmeow:SensoryObservation`	unit, determinacy, granularity, and reference frame are dropped; only the measured physical quantity survives
`ivoa`	`gmeow:SensoryObservation`	the single GMEOW result node is replicated across all four ObsCore axes; axis-specific metadata (units, coverage, resolution) is not preserved
`ivoa`	`gmeow:hasReferenceFrame`	the full GMEOW reference-frame profile is flattened to a coordinate-system string or IRI
`ivoa`	`gmeow:observationResult`	unit, determinacy, granularity, and reference frame are dropped; only the measured physical quantity survives
`ivoa`	`gmeow:observationResult`	the single GMEOW result node is replicated across all four ObsCore axes; axis-specific metadata (units, coverage, resolution) is not preserved
`ivoa`	`gmeow:vantage`	the telescope/facility node is preserved, but agent roles and platform location are dropped
`ivoa`	`gmeow:vantage`	the instrument node is preserved, but agent roles and platform location are dropped
