Some clarifications, the British Library Digital Library Programme uses
timestamps to satisfy the needs expressed in this publicised programme of

This document describes the project that was awarded to Ascertia to replace
the Thales DSE 200 units with Ascertia ADSS TSA Servers.  The document also
describes the use of evidence records to preserve the integrity of the
original data.  The British Library long-term archiving scheme pre-dates the
ERS RFC, however a similar approach of extensible long-life timestamped
evidence records are used.  Other British Library publications describe
their data storage approach.

This is only time-stamping device which does not implement ERS, only
RFC3161 protocol
p%20Server.aspx#2). However it may be used to include archive timestamp into
ERS record... That must be separate service, not part of Thales solution.
