Description

Currently we have the NaturalEnvironmentFeatureType which intended
to provide a place for controlled vocabularies; this is the note from the UML:

Feature-type catalogue of natural environment feature types regarding which MOLES3 observations are made. e.g. SWEET realms, core, mantle, crust, ocean-crust, continental-crust, asthenosphere, lithosphere, ocean, hydrosphere, troposphere, stratosphere, mesosphere - or could be biological taxon. Will be serialized in GML as value of xlink:role, or in ATOM as value of atom:category

This is currently attached to MO_ObservationCollection, but it could be to a more fundamental type, allowing it to be attached to all "first-class" MOLES entities. (Although we don't have
that concept any more because the main entitites now specialise from
19115-2 and O&M ... we'd have to go to composing them in ...).

Change History

Consider the implication that users should only ever download observation collections (even if they only consist of one member). The downloaded "travelling metadata" should be ISO19115
compliant (minimally)?

In terms of how we organise our material? There we have the "physical layout of the collections in the archive", and we want to use discovery metadata.

Much of MOLES is compatible with a standard (ISO 19115) metadata record, because the MOLES classes MO_Platform, MO_Acquisition, MO_Computation, MO_Source are derived from classes in the lineage and acquisitionInformation branches of ISO 19115/19115-2.
See 'Summary: MOLES3' diagram in the MOLES model.

Having 'keyword' (discovery term) on a few classes, and defining a dictionary of NaturalEnvironmentFeatureTypes? provides some pragmatic completion.
