Subject: Re: Attribute date sorting revisited and date ranges explained
That is an option, but not the simple if statement you suggest. Date fields are now all handled the same. To make attribute date fields different then event date fields, each one will have to look up their parent tag and compare to list of attributes vs. events. The parent is not always obvious depending on where the date is accessed in the code. It would not be horribly difficult, but a lot more coding and loss of elegance in date field coding. It might slow down calculations that scan many dates at once.
I will look at other options instead. For example, perhaps it only matters to sort command and can be done in that code and would not be needed any place else. Also distinguishing 1855 from 1855 to 1866 is difficult in current sort method because it is based on one number. Accounting for start date and end date would require addition of secondary sorting criteria (unless the range can be encoded into a single number somehow for efficiency) On nested dates such as FROM CAL 1777 TO BET 1784 AND 1786 These cannot be entered because GEDitCOM II has adopted all GEDCOM options for dates, but that option is not one of them. You do however, have some ways to record such a date: 1. Any date can be followed by a comment in parentheses such as FROM 1777 TO 1786 (1777 was calculated, end date may have been 1784) The comment is never used in date calculations, but will be there for your records. 2. To do the same thing in a hidden field, you can use the custom GEDitCOM II option to attach a memo to the date (or any) field: a. Enter FROM 1777 to 1786 into the field Now when you hover the curse over that field, the comment will appear in a pop-up window rather then the help string for date fields. You can control click again to change the memo. If you are exporting GEDCOM data to share with others using different software, the first option might be better. The second option exports a custom tag right after that date. If you want to both use memos and export GEDCOMs to share in other software, you can run the script "Export Data/Move Memos to Notes" before exporting your data and all memos for a record will appear in notes for the record. They will not be next to the actual date, but will be available for reference. On Feb 21, 2012, at 10:38 PM, Swanfoth wrote: > Actually you should treat all attribute dates as date periods. A
