(a hopefully fairly painless introduction to) linked open data
DESCRIPTION
A presentation given to the NSW Reference and Information Services Group seminar at the State Library of NSW, 4 May 2010. My aim was to provide a non-technical introduction to Linked Data and the Semantic Web that would help people see the possibilities and give them some tools and ideas so that they could go away and start playing with.TRANSCRIPT

It was business as usual in the House of Representatives. At 2.00pm on 11 November 1975, the Deputy Prime Minister, Frank Crean, resumed the defence of the Whitlam government against an Opposition censure motion. But below the surface momentous events were in train. ‘What would happen, for argument’s sake, if someone else were to come in here in a few minutes and say he was now Prime Minister of this country’, Crean hinted cryptically.
As he spoke, government staffers were beginning to empty their offices. Rumours were spreading through Parliament House. Soon the dramatic news was confirmed. The Whitlam government had been sacked by the Governor-General.
Crean’s job was to stall for time while his leader planned his response. Ten minutes earlier, Crean had been at the Lodge discussing tactics with Whitlam and others. There was no doubt in Whitlam’s mind that the House of Representatives held the key. It was in the House that governments were made and unmade, not in the offices of the Governor-General. Surrounded by senior members and staff, Whitlam drafted a notice of motion that he hoped would restore his government to power.
