Dear All,

Following the decisions of the last sig, we invite you to vote if you 
accept the updated scope note of E94 Space primitive .  The old and the 
new scope note follow

===============================================================================================================


      E94 Space Primitive


from (old in 6.2.7)

Subclass of:           E59 Primitive Value

Scope Note:          This class comprises instances of E59 Primitive 
Value for space that should be implemented with appropriate validation, 
precision and references to spatial coordinate systems to express 
geometries on or relative to Earth, or on any other stable 
constellations of matter, relevant to cultural and scientific documentation.

An E94 Space Primitive defines an E53 Place in the sense of a 
declarative place as elaborated in CRMgeo (Doerr and Hiebel 2013), which 
means that the identity of the place is derived from its geometric 
definition. This declarative place may allow for the application of all 
E53 Place properties to relate phenomenal places to their approximations 
expressed with geometries.

Instances of E94 Space Primitive provide the ability to link CIDOC CRM 
encoded data to the kinds of geometries used in maps or Geoinfromation 
systems. They may be used for visualization od the instances of E53 
Place they define, in their geographic context and for computing 
topological relations between places based on these geometries.

Note that it is possible for a place to be defined by phenomena causal 
to it, such as a settlement or a riverbed, or other forms of 
identification rather by an instance of E94 Space Primitive. Any 
geometric approximation of such a place by an instance of E94 Space 
Primitive constitutes an instance of E53 Place in its own right. E94 
Space Primitive is not further elaborated upon within this model. 
Compatibility with OGC standards is considered good practice.

An instance of E94 Space Primitive defines an instance of E53 Place in 
the sense of a declarative place as elaborated in CRMgeo (Doerr and 
Hiebel 2013), which means that the identity of the place is derived from 
its geometric definition. Such a declarative place may allow for the 
approximation of instances of E53 Place defined by the actual extent of 
some phenomenon, such as a settlement or a riverbed, or other forms of 
identification rather than by an instance of E94 Space Primitive. Note 
that using an instance of E94 Space Primitive for approximating the 
actual extent of some place always defines a (declarative)  instance of 
E53 Place in its own right.

Definitions of instances of E53 Place using different spatial reference 
systems are always definitions of different instances of E53 Place.

Instances of E94 Space Primitive provide the ability to link CIDOC CRM 
encoded data to the kinds of geometries used in maps or Geoinformation 
systems. They may be used for visualization of the instances of E53 
Place they define, in their geographic context and for computing 
topological relations between places based on these geometries. E94 
Space Primitive is not further elaborated upon within this model. It is 
considered good practice to maintain compatibility with OGC standards.
