Dates, dating formulae, ages


Recording expressions of dates and durations in the transcribed text.

Names of months, days of the week, or various other periods of time in the text, may be tagged as a reference string (<rs>) for purposes of indexing or other processing, as in the example below:

ἔτι καὶ μηνεὶ <rs type="month"

Explicit dates that appear in the text (whether or not they can be parsed into Julian years) may also be tagged using the <date> element.

ἐτελεύτισεν <date>μινὶ Παυνὶ ἑβδόμι</date>

<calendar xml:id="creationOfWorld">
 <p>"Since the creation of the world"</p>
<!-- -->
<date when="1382-06-28"
μηνὶ Ἰουνίου εἰς <num>κ</num> ἔτους <num>ςωϞ</num>

This example encodes the Roman consular date A.D. 154:

<date from-custom="0154-01-01"

 <persName type="imperialrole="consul"
 <w lemma="et">et</w>
 <persName type="attestedrole="consul"
 <w lemma="consul">
<!-- ... Commodo et Laterano co(n)s(ulibus) -->

(RIB: 452)


From time to time, it is desirable to mark-up durations of time. This is accomplished with the <date> element and the dur attribute. Rules for encoding dur values are codified in the W3C Recommendation on Datatypes.

For the sake of consistency, the following optional typevalues are recommended for specifying the type of duration being marked up.

  • age
  • age-at-death
  • office-span
  • military-service-span
  • marriage-span
