A.2. Document does not have a supplied dateline date - WaxCylinderRevival/frus-dates-project GitHub Wiki

An undated document is a document whose dateline in the original publication is missing a date or is labeled "undated" or the like.

A.2.1. When a precise single date can be reasonably determined, use @when/@ana

A.2.1.1. Examples:

<date when="1919-05-27T16:00:00+01:00" 
  ana="#date_undated-inferred-from-document-head"
  >May 27, 1919, 4 p.m.</date>
<date when="1944-09-12T12:00:00-04:00" 
  ana="#date_undated-inferred-from-chapter-heading"
  >September 12, 1944, noon</date>
<date when="1950-09-15T14:40:00-04:00" 
  ana="#date_undated-inferred-from-document-head"
  >undated</date>
<date when="1953-03-18" 
  ana="#date_undated-inferred-from-document-head"
  >March 18, 1953</date>
<date when="1954-04-13" 
  ana="#date_undated-inferred-from-document-head"
  >undated</date>
<date when="1954-07-30T15:00:00-04:00" 
  ana="#date_undated-inferred-from-document-head"
  >undated</date>
<date when="1954-07-30" 
  ana="#date_undated-inferred-from-document-head"
  >undated</date>
<date when="1955-04-05" 
  ana="#date_undated-inferred-from-document-content-and-sibling-dates"
  >undated</date>

A.2.2. When a precise date range can be reasonably determined, use @from/@to/@ana

A.2.2.1. Examples:

<date from="1946-07-04T17:45:00+01:00" 
  to="1946-07-04T18:50:00+01:00" 
  ana="#date_undated-inferred-from-document-head"
  >July 4, 1946, 5:45 p.m. to 6:50 p.m.</date>
<date from="1950-03-22" to="1950-03-24" 
  ana="#date_undated-inferred-from-document-head">undated</date>
<date from="1950-02-02T11:00:00-05:00" 
  to="1950-02-02T13:00:00-05:00" 
  ana="#date_undated-inferred-from-document-head"
  >February 2, 1950, 11 a.m. to 1 p.m.</date>

A.2.3. When the date or date range cannot be reasonably determined and thus can only be inferred using less precise methods (such as preceding/following document dates or volume date range), use @notBefore/@notAfter/@ana

A.2.3.1. Examples:

<date notBefore="1917-09-25T00:00:00-05:00" 
  notAfter="1917-09-26T23:00:00-05:00" 
  ana="#date_undated-inferred-from-sibling-dates">
    <hi rend="italic">undated</hi>
</date>
<date notBefore="1950-04-06T00:00:00-05:00" 
  notAfter="1950-05-26T23:59:59-05:00" 
  ana="#date_undated-inferred-from-document-content"
  >undated</date>
