Dear Peter,
Yes I agree we need information about addressee / receiver /
Within TEI-CMC
******************
You will find some of our related discussion on this page of the TEI-CMC
group :
http://wiki.tei-c.org/index.php/SIG:CMC/Draft:_A_basic_schema_for_representing_CMC_in_TEI
in two places : 1) section <post> ; 2) microstructure
We used this info in Email and discussion forum (since no element existed
in TEI we had to encode into the <head>)
In tweets we have proposed an <addresse> with attributes (cf.
table).
Oral / speech
***************
There is also an undergoing discussion in the TEI community dealing with
speech / oral. For example when you work on CDS (child directed speech)
you need to explicitly encode into the <u> element tell
to whom a specific oral turn is addressed.
In order to do this in we (in our lab, LRL) created a feature structure
in the Alipe Corpus : you can download here all or parts of the corpus :
http://hdl.handle.net/11041/alipe-000853 and have a look at the
<teiheader> where we ecplian how we proceeded.
"Encoding interactions between characters?"
**********************
eventually have a look on the TEI discussion list :
