Members who read this list may be aware of the work the DLF has done on certificate-based authentication. You will certainly be aware of the widespread library interest in work in this area. Substantial progress is now coming out of the joint Educause Net@edu and Internet2 middleware, directories and public key infrastructure efforts on EDUPERSON. Ken Klingenstein gave a talk on this work at the recent DLF Forum and asked expressly for comment on the work from the digital library community. This effort is now nearing a "version 1.0" status, and the most recent revisions have just been posted to the Educause site, at http://www.educause.edu/eduperson . The work is moving according to a very tight timetable, so comments in the next few weeks are eagerly being sought. These can be supplied by you direct to the editors who are listed on the above web page. I'd also be interested to learn whether it would be worth formulating a DLF response in addition. Kind regards, Dan Daniel Greenstein Director, Digital Library Federation CLIR 1755 Massachusetts Ave, NW Suite 500 Washington DC 20036 phone 202 939 4762
