Helicon ISAPI/Rewrite 3.0 now available

We have only just noticed that Helicon have released version 3.0 of their ISAP/Rewrite module for ISS servers. This replicates the age old Apache Mod_rewrite module that we have all come to rely on. Clients have long lamented the fact that IIS hasn’t been able to do effective URL rewriting and a number are waiting until future promised versions of Windows Server and IIS. Version 3.0 looks to be a major step forward from version 2.0 and with a 45-day free trial – where is the risk? And no we are not on commission! In our projects we couldn’t do without the Apache .htaccess facilities that allow us to design effective addressing schemes. Relying on the vagaries of poorly designed IT implementations to deliver machine/application specific URLs should now be a thing of the past.

OpenID Features on Digital Planet

On his eFoundations blog Andy Powell has recently been commenting that 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

JIS 35(1) Published

The February 2009 issue of the Journal of Information Science has been published.  An article by Nadine Hochstotter and Martina Koch Standard parameters for searching behaviour in search engines and their empirical evaluation introduces the concept of search “evergreens”.  Through an extended longitudinal study they showed that some search patterns in four major engines have stayed stable over a long period.
