[DCRM-L] EAD date normal for Lady Day dates

[James, Kate]

In EAD, you can use the calendar attribute to specify the calendar in the date and unitdate elements.  See the 2nd paragraph in the description here: http://www.loc.gov/ead/tglib/elements/date.html

A non-Gregorian date cannot be rendered in ISO 8601 because ISO 8601 is specific to the Gregorian calendar.  See http://www.iso.org/iso/catalogue_detail?csnumber=40874.  Uncertain dates can be rendered in EDTF, which is an extension of ISO 8601.  Here is the website for EDTF: http://www.loc.gov/standards/datetime/.  EDTF is still in draft status, but a lot of people are using it anyway.

Are you talking about MARC encoding for a bib record? Encode the fixed fields for the modern Gregorian equivalent, and use field 046 for non-modern-Gregorian dates as they appear on the resource. Here's our documentation, if you find it useful: http://folgerpedia.folger.edu/MARC_046_Special_Coded_Dates_%28Bibliographic%29

Off the wall question for DCRM, but I've gone blind trying to hack EAD and ISO 8601 trying to find the answer.

How does one render double-dated (i.e. both Gregorian and Julian dates) or Lady Day dates in a normalized date element?  Or for that matter "or" dates. I'm taking examples from the draft of DCRM(MSS)

<date
normal=" " >1603/1604 March 15</date>

<date normal=" ">1866 or 1867</date>  [Hebrew calendar example]

Etc.?

The easiest solution of course is not to supply a normalized date element and move on, but I did wonder if the answer was out there.
