Metadata (ePistolarium)

The metadata in the ePistolarium documents is contained in the teiHeader element. Each item is a meta milestone element with attributes type and value. The standard types are as follows:

uuid 

the unique identifier of the letter.

correspondence 

the identifier of the correspondence; required.

id 

the identifier of letter in the correspondence; required, must be unique in the correspondence.

date 

the date of writing of the letter. Values are encoded in the Extended Date/Time Format. We use the Gregorian calendar, so Julian dates must be converted. Furthermore, if multiple dates are used in a letter, the last one is used because it approximates the date of sending best (ranges are used for uncertainty).

sender 

the identifier of the sender (may occur multiple times); use value "?" if unknown.

senderloc 

the identifier for the location where the letter was sent; use value "?" if unknown.

recipient 

the identifier of the recipient (may occur multiple times); use value "?" if unknown.

recipientloc 

the identifier for the location where the letter was received; use value "?" if unknown.

Each metadata item is allowed only once, except for "sender" and "recipient.
