RELOAD Philosophy
RELOAD stands for: Reusable Learning Object Authoring and Delivery

Outline
The degree to which educational content can be reused and re-purposed depends on how it is stored, made available, and delivered to the academic user community. Existing learning technology interoperability standards are designed to ensure the reusability of educational content within different authoring environments, content repositories and delivery platforms such as virtual and managed learning environments (VLEs/MLEs). Emerging learning technology interoperability specifications, in particular IMS Simple Sequencing and IMS Learning Design, provide pedagogical frameworks which enable significantly more effective use of learning resources. These specifications are therefore relevant to the basis of the X4L Programme, which focuses on pedagogical outcomes. This project focuses on the development of tools that are based on interoperability specifications being developed by IMS, ADL and the OUNL.The primary aims of this project are to:

- facilitate the creation, sharing and reuse of learning objects and services
- enhance the range of pedagogical approaches realisable through the use of lesson plans

These aims will be achieved through the production of a suite of software tools for authoring and delivery standard-compliant learning objects incorporating comprehensive user guides and exemplar resources. RELOAD will:

- build directly on tools and systems delivered by several earlier JISC projects: including PackageIt! and the Colloquia VLE
- integrate SCORM, a reference framework for instructional content, including the forthcoming version 1.3 which will include the IMS Simple Sequencing Specification
- build on the current developments of the Valkenburg Group on EML (Educational Modeling Language) and the associated IMS Learning Design Specification.

The tools will be of significant value to the JISC and wider community, since they provide the crucial "missing link" which allows users to author and transfer learning objects, in specification compliant format, between authoring and design tools, local and distributed digital repositories, and VLEs.

Overall Approach
RELOAD consists of two strands of deliverables. The first strand focuses on developing a set of open source tools: Content Package Editor, Runtime Delivery System, and the Colloquia VLE. The second, smaller strand aims at producing User Guides and Exemplars for disseminating and integrating the project tools into the JISC community. Both strands of the deliverables will be implemented and made available in three main phases:

- Content: The first phase focuses on producing a definitive content package editor and viewer. The tool will support all aspects of the latest and previous versions of IMS Content Packaging, including IMS Meta-data with IEEE LOM (Learning Object Metadata) vocabulary. It enables content to be aggregated into different structures and tagged with meta-data for exchange between systems and delivery to learners. A package viewer is to be incorporated to enable both authors and learners to interact with packages produced. Both tools will be fully documented and integrated into Colloquia.
- Content - SCORM: In the second phase, the package editor will be extended to support reusable SCORM (version 1.2) objects and the SCORM 1.3 that will include IMS Simple Sequencing, allowing designs to respond to the learner’s actions and to change sequences of content.
- Learning Design: Editors and a runtime delivery system for IMS Learning Design will be implemented. These will also integrate the optional use of Simple Sequencing to sequence a learner’s individual activities, and also ensure that SCORM 1.3 content can be used within the runtime system. The implementation of Learning Design is a significant task, but through open source participation in the Valkenburg Group - see below, this can be expected to have a multiplier effect.
  The implementation of Learning Design will be accomplished in stages corresponding to its three levels of conformance (Level A, B and C), starting with the foundation Level A and then Level B and C simultaneously.

Working with the Valkenburg Group
The project will work collaboratively with the members of the Valkenburg Group, which is an international implementation community formed out of public and private organisations. It has a shared interest in EML, the basis of the IMS Learning Design Specification and in developing tools and systems tools to support its use – editors, repositories and runtime systems. It has agreed to define a shared set of interfaces that will allow both open source and commercial developers to work together to produce interchangeable components that will work together. The majority of participants were interested in developing open source Java implementations and the RELOAD partners fall into this group.

An initial framework has been developed at the system level to outline the main components (authoring tools, repositories and runtime systems and where the interfaces between them lie); and another more detailed set looking at the authoring tools. This proposes a number of modular ‘editors’ similar to the deliverables proposed under RELOAD, each enabling a smaller part of a learning design to be authored and which can be assembled according to need. These will plug into an engine that will translate their input into the required format (EML or Learning Design) and interface to the Repository. The input of considerable expertise from the group, particularly from the OUNL who developed EML and have already made several trial implementations of runtime systems, and of contributed open source software, will have a multiplier effect on the output of the this project.
