Move S15 Observable Entity to CRM? Some possible simplifications of CRMSci Issue 293: Dimension to be discussed at the 38th CIDOC CRM and 31th FRBR CRM meeting Christian-Emil Ore

E13 Attribute Assignment Current S15 Observable Entity – CRM and CRMSci P39 measured E7 Activity P140 assigned attribute to E13 Attribute Assignment P141 assigned E1 CRM Entity O16 observed value E16 Measurement S4 Observation O8 observed O9 observed property type S15 Observable Entity S9 Property Type E55 Type S19 Encounter Event O19 has found object P40 observed dimension O21 has found at E18 Physical Thing E70 Thing E53 Place O24 measured S21 Measurement O12 has dimension ? E54 Dimension P43 has dimension

E13 Attribute Assignment New Exx Observable Entity in CRM moved from CRMSci P39 measured E7 Activity P140 assigned attribute to E13 Attribute Assignment P141 assigned E1 CRM Entity O16 observed value E16 Measurement S4 Observation O8 observed O9 observed property type Exx Observable Entity S9 Property Type E55 Type S19 Encounter Event O19 has found object P40 observed dimension O21 has found at E18 Physical Thing E2 Temporal Entity E53 Place O24 measured S21 Measurement E77 Persistent Item Pxx has dimension ? P43 has dimension E70 Thing E54 Dimension

E13 Attribute Assignment New Exx Observable Entity – CRMSci simplification E7 Activity P140 assigned attribute to E13 Attribute Assignment P141 assigned E1 CRM Entity O16 observed value E16 Measurement S4 Observation O8 observed O9 observed property type Exx Observable Entity S9 Property Type E55 Type S19 Encounter Event O19 has found object P40 observed dimension O21 has found at E18 Physical Thing E2 Temporal Entity E53 Place P39 measured E77 Persistent Item Pxx has dimension ?

E13 Attribute Assignment New Exx Observable Entity – CRM adjustment alternative 1 (not recommended) E7 Activity P140 assigned attribute to E13 Attribute Assignment P141 assigned E1 CRM Entity O16 observed value E16 Measurement S4 Observation O8 observed O9 observed property type Exx Observable Entity S9 Property Type E55 Type S19 Encounter Event O19 has found object P40 observed dimension O21 has found at E18 Physical Thing E2 Temporal Entity E53 Place P39 measured E77 Persistent Item Pxx has dimension E70 Thing E54 Dimension

E13 Attribute Assignment New Exx Observable Entity – CRM adjustment alternative 2 (preferred) E7 Activity P140 assigned attribute to E13 Attribute Assignment P141 assigned E1 CRM Entity O16 observed value S4 Observation E16 Measurement O8 observed O9 observed property type Exx Observable Entity S9 Property Type E55 Type S19 Encounter Event O19 has found object P40 observed dimension O21 has found at E18 Physical Thing E2 Temporal Entity E53 Place P39 measured E77 Persistent Item Pxx has dimension E70 Thing E54 Dimension

E13 Attribute Assignment New Exx Observable Entity – CRM only E7 Activity P140 assigned attribute to E13 Attribute Assignment P141 assigned E1 CRM Entity E16 Measurement Exx Observable Entity P40 observed dimension E2 Temporal Entity P39 measured E77 Persistent Item P43 has dimension E70 Thing E54 Dimension

New Exx Observable Entity – Summing up Delete S4 Observable Entity from CRMSci Introduce new Exx Observable Entity in CRM Subclass of E1 CRM Entity Superclass of E2 Temporal Entity, E77 Persistent Item New domain for P43 has dimension, was E70 Thing, should be Exx Observable Entity Delete S21 Measurement and O24 measured It is currently a subclass of S4 Observation and E16 Measurement With the new class Exx Observable Entity and the adjusted domain for P43 has dimensions, it little new in S21 Measurement compared with the superclass E16 Measurement Where to place E16 Measurement? A measurement is an observation, therefore E16 Measurement should be a subclass of S4 Observation in CRMSci. When CRMSci is generalized to CRM: instances of S4 Observation will be “ordinary” instances of E13 Attribute Assignment. O16 observed value will be P141 assigned O8 observed P140 assigned attribute to
