Feature #1215

Updated by Stefan Eichert over 3 years ago

In addition to files and external references for types, it would be beneficial to also be able to store temporal information with a type. Just the way we do it with other entities. E.g. a certain type of a find "Crescent Shaped Temple Ring" that occurs between 850 and 1050 should include this temporal information. 

 These time spans should only apply to custom types. One solution could be to turn this option on when creating a new custom type. Another could be to create a new type-type like the value type.  
 Or we create a system type like "actor actor relation" for this, then all type trees of this would be under one hood. 

 Manual text proposal: 
 Typochronology types: 
 These types allow to define a timespan (earliest/latest begin and earliest/latest end) for each entry. This mostly applies to archaeological or art history respectively architectural types.  
 One example would be chronological groups for certain archaeological material cultures. Enamelled disc brooches for example would be linked to a type "Carantanian C3" This type would have the timespan from 900 to 1000.  
 Another example would be to link an E22 Sword to the type "Petersen X" that would have a timespan 900 to 1000. 

 This way objects (physical things E18 or E22) that do not have their own timespan defined can be traced chronologically via these chronological types.
