During January and February 2010, initially as familiarisation with previous work, I began experimenting with implementation approaches to the facade software strand of the project. Eventually these converged on a method of persuading an Apache web server to act as the authorising proxy (facade). This has now been written up as WSTIERIA Technical Note 1, available on the project web site.
If you're interested in this approach to supporting federated web services, there should be enough in the document to allow you to have a go yourself using nothing more than a stock installation of Apache and a little scripting (the examples in the document use perl).
I am hoping that by releasing working documents as we go along like this, it may be possible to generate engagement with others in the community with an interest in this area well before the final report appears and the project ends.
The focus is now shifting towards applying the method to real use cases. After presenting an overview of the project to an internal EDINA audience last week, a meeting with representatives from the different application groups within the organisation has been arranged for next week.
In terms of the project work packages, the release of this technical note constitutes completion of task 11 (milestone M1), prototype facade implementation based on standard Shibboleth SP software. Given that the implementation is much simpler (and therefore likely more robust) than orginially envisaged, consisting mostly of configuration rather than code, and has now been written up for a general audience, it will probably also be treated as being at least the first version of task 13, released facade implementation.
