BetterGEDCOM Comparison Spreadsheet (Google Spreadsheet)
A spreadsheet has been set up at Google docs to compare in detail the different data models. This spreadsheet is multi-user, so don't be afraid to go at it. The spreadsheet has several pages (see tabs at bottom). The spreadsheet is at: https://spreadsheets.google.com/ccc?key=0AkvzrkpbaGH0dHBQdmFrckxFQWJnYWJhRnpUazh3Wnc&hl=en
(If a permission box pops up when you attempt to log in to the spreadsheet, just ask for permission and one of the administrators will respond to your request.)
Navigating the spreadsheet
The first page lists all the Records (as called in GEDCOM) or Entities (as called in XML). An attempt has been made to put them in a reasonable order and to place them so that equivalent record/entities are lined up. Models without that record/entity are shown with three dashes. That indicates they specifically are not there, as opposed to unknown or missed.
The remaining pages are for each of the record/entities in order, one per page. The components of each entity are broken out. They are then put in a reasonable order and placed so that equivalent compents are lined up. There may be a hierarchy, so levels are indicated by the number of leading periods.
- This is NOT an easy task to do. There is no science in mapping elements from one system to another. Some are easy and some need to be interpreted. The main idea is to do the best we can. We'll be pulling from this all the structures in use and deciding which structures are best for BetterGEDCOM.
- There is a LOT to do here. The more people who can help, the faster and better it can be done. First step, would be to add information and fill in the tables for any data model and record/entity that is not yet entered. Don't try to get it perfect the first time around. Just try to get it up.
- If you are knowledgeable in specific models, then please, by all means, work on that model and try to get it right in relation to the ones you know about.
- This is a rewarding task. Believe me, you will learn about the various models in detail by doing this. You will then be better informed for your input into the BetterGEDCOM process.
Please go to it. One or two people can't get it done. We need many of you.
