E85 Joining, E86 LeavingIn 33rd CRM-SIG meeting the group, resolving the issue 276 about Formalization of shortcuts, added at the end of the first paragraph of the scope note of the above classes the following sentence: “It may be the initiative of a third party.” E92 Spacetime VolumeIn 33rd CRM-SIG meeting the group the crm-sig discussed about the issues 234, 235,263, and updated the subclasses of E92 and changed the properties. From: Superclass of: Properties: P160 has temporal projection: E52 Time-Span P161 has spatial projection: E53 Place
E4 Period E18 Physical Thing
P10 falls within (contains): E92 Spacetime Volume P132 overlaps with: E92 Spacetime Volume P133 is separated from: E92 Spacetime Volume P160 has temporal projection: E52 Time-Span P161 has spatial projection: E53 Place
Subclass of: E92 Spacetime Volume Scope note: This class comprises instances of E92 Spacetime Volume that result from intersection of instances of E92 Spacetime Volume with an instance of E52 Time-Span. The identity of an instance of this class is determined by the identities of the constituing spacetime volume and the time-span. This class can be used to define temporal snapshots at a particular time-span, such as the extent of the Roman Empire at 33 B.C., or the extent occupied by a museum object at rest in an exhibit. In particular, it can be used to define the spatial projection of a spacetime volume during a particular time-span, such as the maximal spatial extent of a flood at some particular hour, or all areas covered by the Poland within the 20th century AD In First Order Logic: E93(x) ⊃ E92(x) Properties: P164 is restricted by: E52 Time Span To: E93 Presence Subclass of: E92 Spacetime Volume Scope note: This class comprises instances of E92 Spacetime Volume that result from intersection of instances of E92 Spacetime Volume with an instance of E52 Time-Span.

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 allows for the application of all place properties to relate phenomenal places to their approximations expressed with geometries. Instances of E94 Space Primitive provide the ability to link CRM encoded data to the kinds of geometries used in maps or Geoinformation systems. They may be used for visualisation 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. Statement of compatibility with OPENGIS Examples:
In First Order Logic: E94(x) ⊃ E59(x) P7 took place at (witnessed)In 33rd CRM-SIG meeting the group discussed the issue 234, 235 and 263 and changed the superproperties, the scope note of P7. From: Domain: E4 Period Range: E53 Place Superproperty of: E9 Move. P26 moved to (was destination of): E53 Place E9 Move. P27 moved from (was origin of): E53 Place Quantification: many to many, necessary (1,n:0,n) Scope note: This property describes the spatial location of an instance of E4 Period. The related E53 Place should be seen as an approximation of the geographical area within which the phenomena that characterise the period in question occurred. P7took place at (witnessed) does not convey any meaning other than spatial positioning (generally on the surface of the earth). For example, the period “Révolution française” can be said to have taken place in “France”, the “Victorian” period, may be said to have taken place in “Britain” and its colonies, as well as other parts of Europe and north America. A period can take place at multiple locations. Examples:
In First Order Logic: P7(x,y) ⊃ E4(x) P7(x,y) ⊃ E53(y)

A period can take place at multiple locations. It is a shortcut of the more fully developed path from E4 Period through P161 has spatial projection, E53 Place, P89 falls within (contains) to E53 Place. Describe in words.
