Gold-plated CDRs

[Nicholas Thieberger]

Phil,

For a serious archival effort we need to look at developing dedicated 
archives that plan for migrating data in future. The use of CDs now 
is putting off the headache until later when you discover that some 
failed to be written properly or that the copying process may have 
introduced errors and in any case all the files copied will need to 
be checked against the original to determine if they are the same or 
not. While there are extravagant claims about 100 year life for CDs, 
that needs to be balanced against the percentage error rate we know 
(from our own painful experience) exists for CD media. And then there 
is the physical problem of handling all of those disks.

On archiving linguistic data see http://www.language-archives.org/ 
and in particular the discussion on linguistic archiving here: 
http://emeld.org/school/classroom/archives/index.html.

All the best,

Nick Thieberger
