recording time period covered by a document

Dear all,

I was charged with a task of migrating custom metadata schema into TEI. One
of the challenges is representing the period covered in the document, which
in the bespoke encoding was represented as

<coverage-start>1945</coverage-start>

<coverage-end>1946</coverage-end>

It took me quite a while to hunt for the TEI way of expressing similar
concept. Following the trail of <creation> element, which I used to
represent the date of creation of the original document, I concentrated my
search within <profileDesc> and came up with
profileDesc/settingDesc/setting/date

<setting>
    <date from="1945" to="1946"/></setting>

 I wonder if there's any established practice to encode such a general
information about text content? Reaching into language corpora to achieve
that seems rather awkward, especially since phrasing of settingDesc element
(the setting or settings within which a language interaction takes place,
or other places otherwise referred to in a text, edition, or metadata)
seems to concentrate very strongly on 'geographical' or locational aspect
of the setting. Nevertheless, Guidelines examples of settingDesc tend to
record both location and temporal aspect there. I'd appreciate any comments
and solutions adopted by projects.


Best,

Magdalena
