OpenID Features on Digital Planet

On his eFoundations blog Andy Powell has recently been commenting┬áthat the era for OpenID may be dawning and judging by the BBC World Service episode of Digital Planet broadcast on 17th February 2009 he may be right. In this Episode OpenID and Twitter have equal billing – no mean feat!

I’ve certainly been using the tips pointed to by Andy and now use my URI as my OpenID

A Policy Checklist for Enabling Persistence of Identifiers

Nick Nicholas and Colleagues have published an excellent article in Dlib which explores the need for a clear policy framework in establishing a persistent identifier schema.

One of the main tasks of the Persistent Identifier Linking Infrastructure (PILIN) project on persistent identifiers was to establish a policy framework for managing identifiers and identifier providers. A major finding from the project was that policy is far more important in guaranteeing persistence of identifiers than technology. Key policy questions for guaranteeing identifier persistence include: what entities should be assigned persistent identifiers, how should those identifiers be exposed to services, and what guarantees does the provider make on how long various facets of the identifiers will persist.

To make an informed decision about what to identify, information modelling of the domain is critical. Identifier managers need to know what can be identified discretely (including not only concrete artefacts like files, but also abstractions such as works, versions, presentations, and aggregations); and for which of those objects it is a priority for users and managers to keep track. Without working out what actually needs to be identified, the commitment to keep identifiers persistent becomes meaningless.

To make sure persistent identifiers meet these requirements, the PILIN project has formulated a six-point checklist for integrating identifiers into information management, which we present here. »read full article

Building coherence at

Tom Scott and Michael Smethurst have just posted an excellent article in Nodalities discussing the importance of persistent identifiers at the beeb. This is now one of the fastest growing challenges as the world rebels against the machine created identifiers delivered by most CMSs

Excellent faceted navigation/retrieval demo

I’ve managed to capture the brilliant endeca video and have posted it in the library for you to use. It shows the power of a metadata driven retrieval strategy and I’ve used in with many senior teams to counter the “why metadata – use Google” mentality.

Amazon Web Services in Excel Macro

This is an excellent excel macro which I’ve been using to demonstrate the power of web services and persistent identifiers in training courses. The code is accessible and there is alot to learn from it.
