I've been doing a lot of work with METS https://www.loc.gov/standards/mets/ which is a container format with native support for both TEI Headers and EAD. 

METS may be the solution you're looking for if you have both TEI headers and EAD for the same complex object(s).

There are some samples at https://github.com/stuartyeates/METS_metadata_for_complete_beginners / https://doi.org/10.6084/m9.figshare.5606917.v1

Dear all,

Does anybody know about recent work into integrating/interconnecting TEI with EAD? I know of the stuff more than ten years ago but TEI has evolved (and I would assume EAD is not exactly the same either) so: anything more recent?

Kind regards,

Øyvind
