1 Thursday, 22 May 20080 A Handbook of Guidelines on Metadata Usage Jon Mason Metadata Downunder – Metadata, Semantics and Interoperability in Practice Sydney, May 22 nd 2008

2 Thursday, 22 May 20081 Overview Background & Context Why it was developed Who for Environmental drivers Current Status What Next?

3 Thursday, 22 May 20082 Who for & Why Audience: Education & Training sector in Australia & New Zealand Non-expert users of metadata Anyone with an interest ! Why: To de-mystify metadata To better inform intending practitioners To provide a snapshot of relevant activities associated with metadata to broad mix of stakeholders To raise awareness of the role of Standards Australia To strengthen links between Standards Australia & AICTEC

6 Thursday, 22 May 20085 Context Web Services Addressing Metadata Becomes a W3C Proposed Recommendation July 31, 2007. Members of the W3C Web Services Addressing Working Group have released the "Web Services Addressing 1.0 - Metadata" specification as a Proposed Recommendation. Public comment is invited through 30-August-2007 Source: http://www.w3.org/TR/2007/PR-ws-addr-metadata-20070731

7 Thursday, 22 May 20086 Once Upon a Time Ten years ago … – EdNA a national approach to IT infrastructure development – EdNA Metadata “Standard” (1997-1998) extends Dublin Core – Dublin Core Education WG produces draft Application Profile – IEEE LTSC – LOM draft – IMS Meta-Data Specification (1998) Five Years ago – LOM is standardised (IEEE 1484.12.1-2002) – DC Element Set standardised (ISO 15836-2003) – SCORM begins to gain significant acceptance – The Ottawa Communiqué (Intent to Collaborate)

8 Thursday, 22 May 20087 Key Initiatives 2002: The Learning Federation Metadata Specification – Application Profile (mixed namespaces) – Updated a number of times (currently at v2.2) 2003: Higher Education sector – Activities begin focusing on research repositories – Grid projects beginning 2003: Where to for EdNA? – Formal review initiated by AICTEC Standards Committee 2004: VET sector – Activity focused on Learning Objects

9 Thursday, 22 May 20088 Key Initiatives 2004: Need for Broad Guidelines grows – Discussed in AICTEC Standards & Interoperability Committee, but funding not available – Taken forward within IT-19-1 (Debbie Campbell & Jon Mason sketch out requirements) 2005: VETADATA as an Australian SCORM profile – Supporting Repositories of Learning Objects 2005: AICTEC considers ‘common application profile’ – Working Group formed to identify ‘common approach’

10 Thursday, 22 May 20089 Getting Serious IDEA Metadata Workshop – Melbourne (Feb 2005) Educause Conference – Auckland (April 2005) DC-ANZ Workshop – Melbourne (June 2005) Combined IT-19-1 & AICTEC Metadata Working Group Workshop at USQ (April 2006) Content from wiki that developed outputs from above
