I would like to suggest adding a metadata element to
the header (maybe under profileDesc?) This element
would have a series of keys and values; e.g.,
This would allow people to use their inhouse scheme,
which may not always be compatible with what TEI
already has, or extensions like MASTER.
I attach a file (a work in progress) which is an
attempt to encode a Graeco-Roman papyrus manuscript.
You will see at the bottom of the file my <div
type="metadata"> hack to include metadata that I need
for the digital library system I am using (Greenstone).
It seems to me that this data should be in the header.
I did try using the existing conventions, but gave up.
