Condition

EntityDraftv1.0.0-rc.2

A condition: a state of the surroundings over an area and a time, such as the ambient sound, the terrain, the weather or the water. Its properties come from a quantities vocabulary; which list holds it (ambient, terrain, weather or hydrology) says what sort it is.

  • description
    text

    What the record is, in words.

  • identifiers
    List ofDatatypeIdentifier

    Ids the record has in other systems.

  • links
    List ofDatatypeLink

    Open-ended links to other records.

  • createdAt
    date-time (RFC 3339)

    When the record was created, in its producer's system.

  • updatedAt
    date-time (RFC 3339)

    When the record last changed, in its producer's system.

  • location
    DatatypeLocation

    Where the record is, as one point.

  • geometry
    DatatypeGeometry

    The area the condition covers.

  • interval
    DatatypeInterval

    When the condition holds.

  • period
    Id ofPeriod

    The window that repeats when the condition holds, such as night-time.

  • properties
    List ofPartProperty

    The condition's properties, such as air temperature or ground type. A property with axes holds a profile or a series.

  • origin
    DatatypeOrigin

    Where the data came from.

  • evidence
    List ofId ofEvidence

    The evidence the condition rests on.

Links

Points at Records whose ids this record holds, with the field that holds each.

Held by Records that embed this one, with their field that holds it.

Pointed at by Records that hold this one's id, with their field that holds it.
