What are the elements of a BetterGEDCOM data model, including their precise definitions, uses and scope? What are the relationships to these elements?
What IS And What IS NOT Core To The Initial BG Project Replacing GEDCOM?
Are there elements or aspects that can be codified as part of the concept of a genealogical research workspace that need to be identified and considered part of the next phase of work?
Evidence and Source class of entities
A citation entity in a computer database is the relation between a source and a piece of evidence or genealogical fact as well as notations such as footnotes, endnotes and the like.
Templates can be used to afford both users and developers maximum flexibility in using the BetterGEDCOM standard's components. This area discussed how templates can be employed in various parts of BetterGEDCOM.
Family, Group and Relationship entities
Family, Group and Relationship entities are similar concepts with often very different meanings
Events are usually thought of as an association between:
1) one or more people
2) at a date/time or over a period of time
3) at a given location or locations
A property, attribute, characteristic and fact are all of the same concept. They ascribe some value of some property to some entity. PACs exist only in so far as they describe some aspect of the state of a real stand-alone object. Hair color is PAC of a person. A date is an PAC of an event. A role player is PAC of an event. An occupation is a PAC of a person. PACs are naturally recursive and can have their own sub-PACs. PACs can have dates associated with them.
This also encompasses the use of different calendar systems.
