A prerequisite for digital preservation is to be able to capture
and retain the content which is considered worth preserving.
This has been a significant challenge for web archiving,
especially for websites with embedded streaming media
content, which cannot be copied via a simple HTTP request to
a URL. This paper describes the approach taken by the British
Library in capturing and replaying streaming media in a web
archive. A working system is now in place which will lead to
the development of more generic tools and workflows,
contributing to addressing a common challenge for the web
archiving community. The British Library recently archived a
large scale public arts project website,
http://www.oneandother.co.uk, which contains 2,400 hours of
flash videos, streamed over Real Time Messaging Protocol
(RTMP). The case study also presents an overview of the nontechnical
issues relevant to archiving this high-profile website.
