When using a source as evidence for a claim, it is useful to distinguish whether the source is direct (making a direct claim) or is indirect (indirectly supporting a conclusion). By default, source references indicating direct evidence are displayed in green with "Direct evidence for claim" shown in its tooltip. References indicating indirect evidence are displayed in purple and show "Indirect evidence supports this conclusion" in its tooltip. #Gigatrees supports two options for defining evidence models.
Gigatrees supports the
_EVID tag for every source reference. String values of
indirect are supported. Additionally, the abbreviations
I are supported. For example, a source that makes a direct claim would be
0 @I1@ INDI 1 BIRT 2 DATE 7 FEB 2014 3 SOUR @S1@ 4 _EVID direct
Gigatrees also supports #RootsMagic version of the same flag, but located under the quality field
0 @I1@ INDI 1 BIRT 2 DATE 7 FEB 2014 3 SOUR @S1@ 4 _QUAL 5 _EVID D
