Geir, Adrian, Testuser and I worked on how to "source" conclusions from evidence some time back. Several of the evidence developers had some problems with the solutions that had been developed, so I hope to describe the user requirement here.
[It may take me a few step to get this just right and P.S. Louis ... If you are reading this, might you point me to examples in Behold where there are multiple conflicted representations of evidence for birth and/or death?]
During the National Genealogical Society 2011 conference, Tom Jones quoted Helen Leary, saying "Conflicting evidence is incompatible with a conclusion."
Case 1 - Birth but once (v1)
You have been researching Jane Doe for many years. Various records located that might help you reach conclusions about her birth are listed below. Assume that you have created unique record/event record/tag/persona pfact/evidence pfact, for the each of the various items listed, and that for each of those entries, you have developed a full citation.
If you are using personas, please assume that each time you make an entry, you also "believe this is the same person because XXXX."
1. As you entered the events/tags, have you been reporting one of the birth entries as "primary" or "preferred?" Is each each event records/tags, etc. associated with a single source citation? How and where do you report about birth event conflicts?
2. If you assume an event-based system, how do each of the various events/entries about Jane's birth report for Jane's biological mother? (Assume we all believe the conclusion mother is Eliza Jane _ Doe.)
3. What is your conclusion person event/tag/pfact for Jane's birth? What source or sources (what citations) do you report for that conclusion birth event/tag/pfact?
(a) Williams County, Ohio, 1850 U.S. Census XXXX; Janey Doe, age 3, born Ohio; she has apparent brother, Thomas, age 4, also born Ohio. The head of household is John Doe; his apparent wife is Eiza Jane.
(b) Williams County, Ohio, 1860 U.S. Census XXXX; reports Jane Doe to be age 15, born Ohio.
(c) Williams County, Ohio, John Doe Probate file (1863); his will of 1863, mentions minor heir Jane Doe and provides for payment to her when she marries or turns 18, which ever is first.
(d) Williams County, Ohio, Joseph Calle and Jane Doe marriage record, 1867; Jane Doe declares she is over the age of 18.
(e) Williams County, Ohio, 1870 U.S. Census XXXX, Jane Calle, apparent wife of Joseph Calle, she is age 20, born Ohio.
(f) Tombstone of Jane Calle (1851-1879), wife of Joseph Calle, Bryan Cemetery, Williams County, Ohio.
(g) Letter (1930) written by Jane (Doe) Calle's daughter, Marie (Calle) Jacobs. Marie writes that her mother, Jane (Doe) Calle, was born 26 Feb 1850 at Bryan, Ohio; died there not long after Marie was born. Marie states her own birth as December 12, 1877, at Bryan.
(h) Jane (Doe) Calle's brother, Thomas Doe, died 12 Jan 1912. Thomas' Ohio death certificate reports his birth 14 March 1847; parents as John and Eliza Jane Doe. The informant on was reported to be Thomas' widow. Thomas Doe is buried in the same cemetery as Jane (Doe) Calle; his tombstone carries dates 1847-1912.
It's my impression that most software already allows users to enter and source multiple events. This would allow users to enter a separate event/tag/pfact for each of the records in the list above. The problem, at least as I described it to Louis recently (comment in "Ordering of Events by Date
"), is then being able to representing a conclusion event and associating that event with the relevant evidence (the proof for the conclusion). This was the problem Adrian, Geir, TestUser and I worked on last May, but some thought our solution was too complex.
