Issue 380: Qualified properties P79 & P80

Starting Date: 
2018-05-22
Working Group: 
4
Status: 
Open
Background: 

In the 41st joined meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9 and the 34th FRBR - CIDOC CRM Harmonization meeting, the discussion about the  the issue 288, raised   new issue about how give precision or date expression to the qualified properties that have a string as a range, such as P79 and P80. 

Lyon, May 2018

Current Proposal: 

In the 42nd joined meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9 and the 35th FRBR - CIDOC CRM Harmonization meeting, the crm-sig appointed MD to extend the text on the qualified properties P79 beginning is qualified by & P80 end is qualified by, and associate them with P83 had at least duration (was minimum duration of) and P84 had at most duration (was maximum duration of), in a way that the qualifications accommodate difference of opinion on the relevant timespans.

Dear All,

here my attempt to improve the definition of P79, P80. Question: Shouldn't our RDF guidelines contain a recommendation how to register "ongoing" time-spans? Anyone an idea of a good practice??

Best,

Martin

OLD:

P79 beginning is qualified by

Domain:              E52 Time-Span

Range:                E62 String

Subproperty of:   E1 CRM Entity. P3 has note: E62 String

Quantification:    many to one (0,1:0,n)

Scope note:         This property qualifies the beginning of an E52 Time-Span in some way.

The nature of the qualification may be certainty, precision, source etc.

Examples:         

§  the time-span of the Holocene (E52) beginning is qualified by approximately (E62)

P80 end is qualified by

Domain:              E52 Time-Span

Range:                E62 String

Subproperty of:   E1 CRM Entity. P3 has note: E62 String

Quantification:    many to one (0,1:0,n)

Scope note:         This property qualifies the end of an E52 Time-Span in some way.

The nature of the qualification may be certainty, precision, source etc.

Examples:         

§  the time-span of the Holocene (E52) end is qualified by approximately (E62)

NEW:
P79 beginning is qualified by

Domain:              E52 Time-Span

Range:                E62 String

Subproperty of:   E1 CRM Entity. P3 has note: E62 String

Quantification:    many to one (0,1:0,n)

Scope note:         This property associates an instance of E52 Time-Span with a note detailing the scholarly or scientific opinions and justifications about the beginning of this time-span concerning certainty, precision, sources etc. This property may also be used to describe arguments constraining possible dates and to distinguish reasons for alternative dates. 

Examples:         

§  the time-span of the Holocene (E52) beginning is qualified by “The formal definition and dating of the GSSP (GlobalStratotype Section and Point) for the base of theHolocene using the Greenland NGRIP ice core,and selected auxiliary records” * (E62)

P80 end is qualified by

Domain:              E52 Time-Span

Range:                E62 String

Subproperty of:   E1 CRM Entity. P3 has note: E62 String

Quantification:    many to one (0,1:0,n)

Scope note:         This property associates an instance of E52 Time-Span with a note detailing the scholarly or scientific opinions and justifications about the end of this time-span concerning certainty, precision, sources etc. This property may also be used to describe arguments constraining possible dates and to distinguish reasons for alternative dates.  

Examples:         

§  the time-span of the Holocene (E52) end is qualified by  “still ongoing” (E62)

In the 43rd joint meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9; 36th FRBR - CIDOC CRM Harmonization meeting, the sig reviewed MD’s proposed definitions. The definition for P79 was accepted and the definition of P80was accepted as a working definition.
P80 end is qualified by poses a problem for CRM in that there is no way to model time intervals that are ongoing at the time of documentation (or time intervals that are possibly ongoing at the time of the documentation –i.e. time intervals of situations for which it is not known whether they have ended).
DECISION: GB is to contact DP on the subject of temporal reasoning.
