$ mkdir mail/foaf-protocols 
$ cd mail/foaf-protocols
$ wget http://lists.foaf-project.org/pipermail/foaf-protocols/2010-{January,February,March}.txt.gz && gunzip *gz
$ cd ../.. 
 (you could stay in this directory if you want a sep index)
$ e.console

=> [/mail/foaf-protocols/2010-February.txt, /mail/foaf-protocols/2010-January.txt, /mail/foaf-protocols/2010-March.txt]

mail is of course identified by message-ID:

   (E E::SIOC+'from').rangePO 'henry.story@bblfish.net',1
=> [/mail/foaf-protocols/2010-March/97]

m=((E E::SIOC+'from').rangePO 'henry.story@bblfish.net',1)[0].resource :mail

message identifier, it can be plugged into gmane :

or local DB (filesystem really)

 wrote some domain-specific views for mails (suggestions welcome)

a 'long tail' approach might be good, so you dont miss the important threads if ignoring a list for a week/month/forever:

theres a generic (Exhibit - inspired) facet-top which just counts the most occurences of p/o:

http://m/ma/foaf-protocols/*/*?view=top&face&a=sioc:from

668	
198	henry.story@bblfish.net
111	home_pw@msn.com
71	melvincarvalho@gmail.com
48	kidehen@openlinksw.com
32	Bruno.Harbulot@manchester.ac.uk

a custom domain-specific aggregation

http://m/ma/foaf-protocols/*/*?view=topthreads

39	[foaf-protocols] FOAF+SSL and root certificates
35	[foaf-protocols] FOAF+ssl, access control.
29	[foaf-protocols] rsa / cert Ontology questions.
24	[foaf-protocols] foaf+ssl working on Internet Explorer
22	[foaf-protocols] Lack of browser support

suporting these kind of ad-hoc URI-specified workflows and making them fast drove the refactoring of http://gitorious.org/element 
 and thats proably why it uses JSON almost everywhere, and the innate ruby Hash implementation rather than a RDF library - URIs are identifiers + conneg works anyways


a thread-reconstructor finds entire thread given a message
