Dear All,
in analogy to the scope note of E94 space primitive, I propose the
following change of scope note:
Old:
This class comprises instances of E59 Primitive Value for spacetime
volumes that should be implemented with appropriate validation,
precision, interval logic and reference systems to express date ranges
and geometries relevant to cultural documentation. A Spacetime Primitive
may consist of one expression including temporal and spatial information
like in GML or a different form of expressing spacetime in an integrated
way like a formula containing all 4 dimensions.
An E95 Spacetime Primitive defines an E92 Spacetime Volumein the sense
of a declarative spacetime volumeas defined in CRMgeo (Doerr & Hiebel
2013), which means that the identity of the spacetime volumeis derived
from its geometric and temporal definition. This declarative spacetime
volumeallows for the application of all E92 Spacetime Volumeproperties
to relate phenomenal spacetime volumesof periods and physical things to
propositions about their spatial and temporal extents.
Definitions of spacetime volumes using different spacetime reference
systems always result in definitions of different spacetime volumes
approximating each other.
Note that it is possible for a spacetime volume to be defined by
phenomena causal to it or other forms of identification rather than by
an instance of E95 Spacetime Primitive. In this case, this property must
not be used for approximating the respective instance of E92 Spacetime
volume with an instance of E95 Spacetime Primitive.
E95 Spacetime Primitive is not further elaborated
upon within this model. Compatibility with OGC standards are recommended.
*New:*
“This class comprises instances of E59 Primitive Value for spacetime
volumes that should be implemented with appropriate validation,
precision and reference systems to express geometries being limited and
varying over time on or relative to earth, or any other stable
constellations of matter,relevant to cultural and scientific
documentation. A Spacetime Primitive may consist of one expression
including temporal and spatial information like in GML or a different
form of expressing spacetime in an integrated way like a formula
containing all 4 dimensions.
An E95 Spacetime Primitive defines an E92 Spacetime Volume in the sense
of a declarative spacetime volume as defined in CRMgeo (Doerr & Hiebel
2013), which means that the identity of the spacetime volume is derived
from its geometric and temporal definition. This declarative spacetime
volume allows for the application of all E92 Spacetime Volume properties
to relate phenomenal spacetime volumes of periods and physical things to
propositions about their spatial and temporal extents.
Definitions of spacetime volumes using different spacetime reference
systems always result in definitions of different spacetime volumes
approximating each other. It is possible for a spacetime volume to be
defined by phenomena causal to it, such as an expanding and declining
realm, a settlement structure or a battle, or other forms of
identification rather than by an instance of E95 Spacetime Primitive.
Any spatiotemporal approximation of such a phenomenon by an instance of
E95 Spacetime Primitive constitutes an instance of E92 Spacetime volume
in its own right, i.e., the approximating one.
E95 Spacetime Primitive is not further elaborated upon within this
model. Compatibility with OGC standards are recommended.”
Best,
Martin
