RELOAD Overview Bill Olivier Bolton Institute

RELOAD Aims Standards-based Editor and Runtime toolset –Metadata –Content Packaging –SCORM (& ideally Simple Sequencing also) –Learning Design Based on integrating 2 previous JISC tools –PacMan Editor –PackageIT! Editor (Colloquia)

RELOAD Aims But NOT possible to integrate !!! –Different architectures, different strengths –Different editing use cases: 1.Pacman: package an existing web site 2.PackageIT!: drag’n’drop resources to create new –Pacman used Merlin, but this XML DTD-based –For IMS, needed to support XML Schemas

RELOAD Aims So took best ideas from both & created new: –Core XML engine –Schema driven (to support any XML schema / version) –Helper (configuration) files UI field names & pop-up help mapped to schema fields Switch fields off & on (app. profiles & special editors) Location & other properties of UI widgets –Default automatic table-view editor –Form-view and some drag’n’drop editors (CP) –Plug-In alternative UIs can be created by others

JDOM / JAXP wrapper UI 2 DOM (Xerces) IMS CP/MD/SS/L D XML docs UI 1 Controller mapped to DOM UI 4 UI 3 Plug-in Editor Interface Persistent Store / Repository XML Display helper file XML Schema Views Controller/s Model RELOAD Editor Architecture

Intetgrating SCORM Engine ADL have a single user SCORM web engine This is being stitched into Colloquia Will be able to run SCORM content offline Send results back to tutor Learner keeps own record Report from the coal face…

What about LD Runtime? Build on Colloquia –Open source, Java, P2P learning environment –Core elements: activities, people, resources –Has both authoring and runtime facilities –Already has LD services: conferencing and –Communications mechanism can also be used for LD Notifications –No purchase cost, low running cost, v.scalable –Cross platform What multi-user, coordination architecture?
