UK LOM Core How and why it came about Charles Duncan, Intrallect C.Duncan@intrallect.com
2
Timeline April 2002: proposal to UK Metadata in Education Group established UK Common Metadata Framework July 2003: UKCMF renamed UK LOM Core, version 0.1 released by CETIS 2003: widespread adoption of UK LOM Core in large-scale UK projects May 2004: version 0.2 released by CETIS, establish optionality and detailed guidelines Aug 2004: Joint meeting of UK MEG and CETIS Metadata SIG, handover of UK LOM Core to BSI considered Dec 2004: draft version 0.3 released, structure and purpose clarified, minor details changed 2005/6: Decision against transferring ownership to BSI. No further development 2007: Becta Vocabulary Bank – mostly thesauri for classification Nov 2007: Learning Materials Application Profile: Scoping study for application profile extending beyond IEEE LOM
3
General Information model developed but no bindings Initial purpose was to survey common practice, later changed to proposing guidelines with a goal of increasing interoperability of metadata instances Followed CanCore as an example Until late 2007 based entirely on IEEE LOM
4
Process Open meetings CETIS Metadata Special Interest Group Draft documents open for comment International discussion CEN/ISSS, IMS, DCMI Trial adoption on many large-scale projects Use is not mandated but existence of guidelines much appreciated
5
April 2002 Proposal to UK Metadata in Education Group established UK Common Metadata Framework Proposed scope: Optionality of metadata fields Vocabularies Use of metadata in content packages
6
July 2003 Mandatory fields (19): General Indentifier Catalog Entry Title Language Description Lifecycle Contribute Role Entity Date Meta-metadata Indentifier Catalog Entry Contribute Role Entity Date Language Metadata Schema Technical Format Location Rights Copyright and other restrictions Description UKCMF renamed UK LOM Core, version 0.1 released by CETIS
7
Contd… Vocabularies Identified Learning Resource Type as an area requiring further work Classification (examples given) National Curriculum 5-14 learndirect Subject Classification (Levels 1-2) Joint Academic Coding System Dewey Decimal Classification (Summary Levels 1-2)
8
2003 Widespread adoption of UK LOM Core in large-scale UK projects Used by: Jorum – UK national repository for post- school education Resource Discover Network – Learning Teaching Support Network Exchange for Learning Programme
9
May 2004 Mandatory fields (18): General Indentifier Catalog Entry Title Language Description Lifecycle Contribute Role Entity Date Meta-metadata Indentifier Catalog Entry Contribute Role Entity Date Language Metadata Schema Technical Format Location Rights Copyright and other restrictions Description Version 0.2 released by CETIS, establish optionality and detailed guidelines
10
Contd… Vocabularies UK Educational Contexts Learning Resource Type survey of many options included but no definite recommendations Classification UK Educational Levels vocabulary developed
11
Aug 2004 Joint meeting of UK MEG and CETIS Metadata SIG, handover of UK LOM Core to BSI considered Recognition of long-term sustainability
12
Dec 2004 Draft version 0.3 released, structure and purpose clarified, minor details changed Refinements mostly in preparation for BSI adoption vCard ambiguities clarified Mandatory fields – no changes Vocabularies – no changes Classification – no changes Required, Recommended, Optional used
13
2005/6 Decision against transferring ownership to BSI. No further development BSI rejected because standard documents are not openly and freely available No further development because initial need had been satisfied
14
Oct 2006 Becta launch Vocabulary Bank and Studio Zthes-based vocabularies and taxonomies Open to all to download Web services interface for dynamic lookup Studio allows authorities to create vocabularies Aim to map taxonomy nodes to a central spine to offer Crosswalks Future-proofing
15
Nov 2007 Learning Materials Application Profile: Scoping study for application profile extending beyond IEEE LOM Recognition that IEEE LOM is insufficient Need to create application profiles from multiple schemas Recommendations needed for each schema
16
Contd… Domain metadata General discovery Education Accessibility Digital Rights Curation/preservation Repository management Attention/usage/ratings Resource specific Scholarly communications Assessment Complex objects Images Moving images Geo-spatial Technical People and organisations
17
Lessons Learned UK LOM Core adoption came from satisfying a need not by mandating There was a vacuum of advice that needed to be filled Becta Vocabulary bank is performing a similar function Application profiles are successful if they help users/implementers even without “top-level” support but are not static and will need replacing periodically
