I am pleased to report that work has begun in earnest to incorporate EDTF into ISO 8601. ISO recently approved a work item for an “8601 Part 2”. (I don’t know if this really means “Version 2”, or if there will actually be two parts.) And so a Working Group has been convened, and I have joined. Unfortunately I have had to miss the past two calls, when EDTF has been discussed, but from the minutes, it seems that much of it is being well-received. This is all very preliminary of course.
I want to bring to your attention several changes that are being suggested. These suggestions are tentative as they have not been discussed yet within the group, just suggested. But I want feedback from this group, if anyone objects to any of these suggestions. (Personally, I think they’re fine.)
·‘?’ (question mark) currently means “uncertain”, ‘~’ (tilde) means “approximate, and ‘?~’ means “uncertain as well as approximate”. The suggestion is to replace the latter with a single character and the suggested character is ‘%’ (percent).
·‘u’ means unspecified, and the suggestion is to change that to ‘!’ (exclamation).
·‘y’ is used at the beginning of the date string to signify that the date is a year exceeding four digits. The suggestion is to change this to ‘Y’ (upper case).
·‘unknown’ and ‘open’ : the suggestion is to replace these with single characters, and the suggested characters are ‘*’ and ‘&’ (asterisk and ampersand).
·Numeric values for seasons:
21 = Spring
22 = Summer
23 = Autumn/Fall
24 = Winter
The suggestion is to rename these four, and expand the list:
·21 = Spring - Northern Hemisphere
·22 = Summer - Northern Hemisphere
·23 = Autumn/Fall - Northern Hemisphere
·24 = Winter - Northern Hemisphere
·25 = Spring - Southern Hemisphere
·26 = Summer - Southern Hemisphere
·27 = Autumn/Fall - Southern Hemisphere
·28 = Winter - Southern Hemisphere
·31-34 for Q1 - Q4 ( 4 periods of 3 months each)
·41-43 for Quadrimester (3 periods of 4 months each)
·51-52 for Semestral (2 periods of 6 months each)
The next scheduled call is Tuesday, June 23, so if you have concerns about these suggestions, please post them before then.
