A paper by Paul Walk of UKOLN entitled Software as a Service and Open APIs has been accepted for the M2009 Museums and the Web Conference to be held in Indianapolis, USA over 15-18 April 2009. This paper will form the background to a mini-workshop APIs – how and why which will be conducted by his colleague Brian Kelly. The workshop will consider ways in which open APIs and Software as a Service (SaaS) are being exploited within the sector and seek a better understanding of the best approaches to take to maximise the potential benefits of this technology.
