The SPASE data model

See  their wiki.

Key concepts (as of V2.1.0 -  pdf):

With the exception of Granule and Person, every resource has a common set of core attributes. The core attributes provide textual descriptions of the resource and the capability to reference external sources of information (Information URL). It also describes the context of the resource in the larger data environment. This context consists of associations with other resources (Association) and with previous versions (Prior ID). These attributes are grouped in a Resource Header and consists of:

  • Resource Name
  • Alternate Name
  • Release Date
  • Expiration Date
  • Description
  • Acknowledgement
  • Contact
  • Information URL
  • Association
  • Prior ID

The SPASE Data Model allows for additional metadata to be embedded within a SPASE description. Every Resource Type has an "Extension" element which can contain metadata compliant with other data models. The "Extension" element has a SPASE data model type of "Text", but is not limited to alphanumeric characters and may contain tagged information.

The PDF has an excellent data dictionary, and includes the entire controlled vocabulary (I think).

There are some explicit sub-elements of parameter descriptions, which may be of use to both MOLES and the new SWE phenemenon description:

  • Cadence
  • Caveats
  • Coordinate System
  • Description
  • Field
  • Fill Value
  • Mixed
  • Name
  • Parameter Key
  • Particle
  • Rendering Hints
  • Set
  • Structure
  • Support
  • Units
  • Units Conversion
  • Valid Max
  • Valid Min
  • Wave

however, there is obviously a semantic mixing in there that we'd want to unpick ... one couldn't easily reason on the basis of this.

The role vocabulary has a couple of good additions to those we have seen before (e.g. former-pi):

  • Archive Specialist
  • Co-Investigator
  • Contributor
  • Data Producer
  • Deputy-PI
  • Former-PI
  • General Contact
  • Metadata Contact
  • Principal Investigator
  • Project Scientist
  • Publisher
  • Scientist
  • Team Leader
  • Team Member
  • Technical Contact
