Questions and Concerns
• Does reuse really work?• Metadata are something of the past. Now we use
Google and no-one is metadata tagging anymore.• Why using standards, they are too restrictive.
Which standards anyway? The good thing about standards is that there are so many to choose from
• You may have these questions yourself or you may encounter people with these questions
European Schoolnet
But First
• Learning technology has redefined terms– Metadata– Learning Object– Reuse
• Illustrative Examples
European Schoolnet
Metadata• Late sixties: Origin in database and software
development. Originally: Data about Data; e.g. datatype, description, owner, etc
• 1978: Meta-database driving applications• 1995: Platform for Internet Content Selection
(PICS)• 1995: Dublin (Ohio) Core Metadata Initiative• 1998: European Treasury Browser Project• 1999: DC extensions for education• 2002: Learning Object Metadata. Now in LT:
Data about an object• http://orc.dev.oclc.org:5103/metamarda-l/msg00097.html
European Schoolnet
Curent metadata schemes for Learning Resources
• Application Profiles for DC– ELR MES (ETB project)– DC extensions for education
• LOM– Standard since June 2002– Various Application Profiles Under
construction
• Ottawa agreement to converge
European Schoolnet
Learning Object
• Origin: The Object Oriented Approach in Software Engineering: encapsulated behaviour, information hiding, inheritance, classification, avoiding the ripple effect
• Original question: Can we apply OO techniques to the development of multimedia resources to facilitate reuse in education?
• The LOM standard defines a Learning Object as any entity, digital or non-digital, that may be used for learning, education or training.
European Schoolnet
Reuse
• Software Engineering– A software engineer develops a piece of software A;
(another) software engineer adapts and integrates it as A’ in his own program. Many users use A and A’
– Find, Evaluate, Obtain, Adapt, Integrate
• Learning technology– A teacher produces a LO A and uses it in his classroom– The teacher reuses it in another classroom– Another teacher reuses it also in his classroom with or
without modifications
European Schoolnet
Illustrative Examples
• Current practice: European Learning Resource Brokerage system
• Current development with Learning Objects: The Celebrate project
• Current development for School Administration: The Schools Interoperability Framework

What does it take to work?
• Resources
• An application profile for a metadata system
• A brokerage system
• Learning Content Management Tools
• Learning Management Tools
• Economic, organisational feasibility
European Schoolnet
European Learning ResourceBrokerage System
• Result of the European Treasury Browser (ETB) project
• Dublin Core Application Profile– Extensions to the DC MES– ELR thesaurus of 1200 terms in 9 languages for schools– Controlled Vocabularies– Resource Description Framework (RDF) binding
• 1st generation brokerage system• About 12,000 resource descriptions• Quality descriptors• Collections of trusted resources
