Dear Mum,Weather here fine.

Meetings interesting but I’m not sure I understand what everyone is on about; most of the words are familiar but don’t seem to make any sense. For example, I heard someone talk about punting there didn’t seem anywhere suitable.

Hope you are keeping well, your loving son,

Adam

Consequences of the Process

We need people (JISC projects) to be involved earlier

Enterprise Web Services v2 – Outcomes

Charter available on IMS website Guiding Principles

more SOA Specificity by application profile But still rooted in MIS-VLE integration

Currently a Base Document (final) Interop demos in May: Informs, Desire2Learn, Oracle,

Blackboard (?)

Outcomes Service Interface

Very CRUD-y + a selection of ReadIdsByCriterion() + possibly Discover(CQL)

Requirement is “final” grades from LMS to MIS

What is Needed?

Validation Exploration in context More business-process view of methods REST formulation

Learning Tools Interoperability v2

Loosely based on Tools Interoperability Guidelines v1 (available from IMS site, as is LTI v2 charter)

Recent resurgence of activity A lightweight tool launch protocol, paupers’ integration On-demand provisioning Change of style

Away from WS* Inspired by Web2.0 Pull More soa-ish, open Shibboleth compatibility

LTI Interactions (stylised)User VLE Tool

Serve page

Invoke tool Handover (trust)

Tool acquires data

User interacts with tool (no VLE interaction)

Return “outcomes”

Maybe not vle

What could LTI do?

Return data Score Outcomes (Enterprise WS v2) CMI QTI Results XHTML CP ….

What Tools – use your imagination!

What is needed?

Validation Concerted simplification Pushing the concept

Common Cartridge

Charter and presentations on the IMS website (and elsewhere) It’s a CM/DN Draft Scope of CC

Basic CP DC metadata bound to LOM QTI (for 6 question types) Authorisation Service Forum placeholders Weblinks (!) NOT Tools Interoperability

The Common Cartridge Alliance Testing Engine Development

The Authorisation Service

Import or use level assertions On package (cartridge) or resource

Honour! Simple

Send VLE URL, CC id, a PIN/key to publisher Get back a yay or nay VLE caches per user

Test Engine

Sponsored by JISC and 8 others Outline

Open source, copyrighted to the IMS Global Learning Consortium. Testing tool and future enhancements will be made available free-of-charge

to the sponsors and the members of the CC Alliance. Testing tool will be made available to the public for self-administered use

Phases Configured specifically for testing cartridges against the CCv1.0 as defined

using the IMS SchemaProf tool. Testing tool can be automatically configured by importing a given set of

SchemaProf files. Potentially applicable to other related Content Packaging based profiles.

Common Cartridge Schools (aka CCK12)

See the IMS website but…

Child manifests, multiple orgs, multi-lingual Question types and formatting “Learning Standards” Lesson plans SIF Results Metadata and Vocabularies

What is Needed?

Hard-nosed spec validation A transcoder?

Digital Interactive Content Exchange

Difficult to tell where this one is going…

Odds and Sods

QTI 2.1 CCK12 demanding the formatting capabilities Enthusiasm for application profiling

LD Discussion on lightweight specs
