As promised during the webinar, the correct link for the museum! You can search and browse a portion of the collection held in the Powerhouse Museum in Sydney, Australia. Browse around! Search, read, zoom - add tags! This is a site at which to have fun, learn new things, spark new thoughts.
The team at the museum have made great use of readily available technologies and user generated content to augment the records and formal taxonomies that existed at the museum. Sites such as Flickr, tools such as OpenSearch, and licensing and use models from Creative Commons are combined to provide access to the data by as wide a variety of users as possible - users who become potential visitors; potential patrons. The design and interaction models are simple and elegant; the search and browse mechanisms are powerful; the images and image manipulation tools allow you to see great detail and experience the pieces wonderfully from afar.
If you are so inclined, I highly recommend you read through the "About" tab, and follow the links from there to the papers and blogs about how they've built the site. It's an interesting read, and a great way to be inspired - yet again - by those serving in institutions that preserve and promote our global heritage.
