Persisting with Identifiers
Getting a handle on things from an archivist’s
perspective…
19th July 2012
LSE’s Digital Library
• Born-digital items, digitisation projects,
e-theses, public lectures
• From the Library, the School, and
beyond
• Developed by representatives from
across the Library
Reinventing the wheel?
PIDs to the rescue!
• Compliance with best practice
• Designing and using a schema
delivers greater control over files
• They aid long term preservation by the
fact that they do not change
• PIDs can be used to unify objects and
metadata
What we needed
• PIDs that are:
• Opaque (but not too opaque)
• Long (but not too long)
Points In Discussion
• Practical in Discoverability: PID format,
transparency and length
• Pinning it Down: What gets a PID and
when
• Resolvers: ARK, DOI, Handle, URN,
NOID and PURL.
Conclusions
• More complicated than you might
think!
• Most important thing is persistence
