Unlocking Museum Systems with Open Source

1 gefällt mir•1,107 views
Sides to accompany Presentation at Open Source Panel, MCN 2010, October 28th. Drawing examples from web projects at the Victoria and Albert Museum, I will identify free and open source technologies that have enabled us to deliver value to colleagues and visitors alike. Furthermore, we will see how these technologies - when combined with open standards - can provide a powerful toolkit for working with legacy and proprietary systems. This allows "just-in-time" features to be added to existing systems outside costly or time-consuming upgrade cycles. Overall, I will share some approaches that could be useful for other institutions wishing to engage technical staff and save on licensing software.
