Feature #905

Updated by Alexander Watzinger over 4 years ago

We would like to use the 4.0.0 release to also update the CIDOC CRM version (at the moment 5.0.4-1). 

 Kindly received recommendation from George Bruseker (September 2019) was to update to CIDOC CRM 6.2.1. which is the last published version available at http://www.cidoc-crm.org/versions-of-the-cidoc-crm 

 After implementation check: E53 range for P53 but P53 is not shown at E53 view 

 *Update* 

 There are some new classes and properties, others were removed. It doesn't seem to affect our existing instances but nevertheless a few properties doesn't "fit" in our system because they have URLs as a domain (our system has a foreign key on domain which must match an existing class). The are:  

 <pre> 
 ['P3', 'P57', 'P79', 'P80', 'P81', 'P81a', 'P81b', 'P82', 'P82a', 'P82b', 'P90', 'P168'] 
 </pre> 

 Also some properties are linked as sub_properties_of properties with the *i* postfix. Since we don't use inverse properties they are linked to there counterpart without *i*:  
 <pre> 
 P10i, P130i, P59i 
 </pre> 

 Mostly this seems to have to do with this change: 

 <pre> 
 8. CRM time extension 1.0 Encoded in RDFS 

 Since the Time Primitive of the CRM can not directly be implemented in RDF Triple Stores, we define in this extension 
 of 4 properties replacing P81 and P82 adequately using xsd:dateTime.  
 Property P81 is dedicated for modeling the Time-Span's maximum known temporal extent i.e. ongoing_throughout.  
 Property P82 is for modeling the minimum outer bounds of events i.e. at_some_time_within.  
 P81 has its time interval redefined by P81a and P81b. Similarly, we redefine P82 by P82a and P82b. 
 </pre>
