METS Awareness Training METS and Learning Objects

What are learning objects? a reusable unit of instruction for teaching, typically in e-learning. Wikipedia small electronic units of educational information that are flexible, reusable, customizable, interoperable, retrievable, facilitate competency- based learning, and increase the value of content Univ. of Wisconsin

IMS Content Packaging (IMS-CP) A specification for sending learning objects from one program to another, facilitating easier delivery, reuse and sharing of materials CETIS standards briefing Transmit content from one VLE to another Import content into a VLE from a resource network, repository or publisher Export content so that it can be reused by other departments or institutions Assemble or aggregate existing content into a single package for delivery Transfer content from an authoring tool to a VLE or repository

Content vs. Presentation – METS: tends to make strong distinction between content and presentation – IMS-CP: presentation is content – METS segregates presentation in optional, IMS-CP includes it in Nonetheless: – There are assigned places for content and presentation in each so they can be mapped to each other Some divergence in approach

Embed IMS-CP within METS Some possible approaches

Some possible approaches Store learning objects as IMS – generate METS files when needed Store learning objects as METS – generate IMS files when needed XSLT METS IMS-CP
