Kinds of Specifications/Standards


Specifications/Standards That Enable the eLearning Marketplace• Data Specifications:

• Allow systems to have a common understanding of

content being exchanged or accessed

• Interface Specifications: • Allow software components to talk to each other in a standard way (consumer oriented)

• Protocol Specifications:• Allow machines to talk to each other in a standard

way (provider oriented)


Examples (Content/Repository Related Specs/Standards):

• Data Specifications - including but not limited to:• Content Packaging• LOM• SCORM Packaging• Dublin Core• METS Schema• Etc…

• Service Interface Specifications - including but not limited to:• Repository OSID• JSR 170• Etc…

• Protocol Specifications - including but not limited to:• Web Services• SRW• DRI• Z.39.50• Etc…


Open Service Interface Definitions (OSIDs)• Service Oriented Architecture (SOA) Specifications for

eLearning

• Interface specification for “Plug-In” interoperability• Reduce cost and effort for custom integration

• Future-proof against changing technologies

• Increase opportunities for Collaboration

• Increase Mobility of applications among enterprise infrastructures

• Enable Marketplace of Pre-integrated software components

• Java versions released in Spring 2003, Currently Ver. 2.0

• PHP versions released Spring 2004, Currently Ver. 2.0• Middlebury -- Segue

• Moodle?

• Objective-C version due later this year

• Version 3.0 in development (IMS Maintenance)


Current OSID’s

• Course Management• Repository• Assessment• Grading

• Authentication• Authorization• SQL• Logging• Filing• Dictionary• Hierarchy• Agent• Shared• ID• User Messaging• Scheduling• Workflow

“Common Services”“Educational Services”


The Content Consumer

• Choice• My apps should just work with the content I need

• I should be able to “shop around” for and “mix and match” both applications and content

• I can’t wait for my favorite application to support the content I want.

• I need to use more than one repository at a time

• I need a standards based solution


The Content Provider

• Product to Market• Consumers should be able to access my content easily

• I need to liberate my content from dedicated client software

• My service should be able to survive technology change

• I need to mitigate cost of technology change

• My customer required a standards based solution
