Packaging update and requirements

Overview

OAI Object Re-use and Exchange (ORE) What it is Where it is at

Content Packaging 1.2 What it is Where it might go: split and standardisation

IEEE RAMLET What it is Where it is going: implementation strategies

Packaging service What it could be

OAI Object Re-use and Exchange

From the digital repository world (compare OAI PMH) Consists of:

Abstract data model Vocabulary Atom profile

Meant for the exchange of web resources Alpha out now, beta by March 3 UK ORE information day April 4, Southampton

What is new in IMS Content Packaging 1.2

General housekeeping: Metadata element and other fixes Resource vocabulary Organization vocabulary Completely new documentation set

New functionality: New element to indicate alternative resources with different

accessibility characteristics New element to include remote parts of remote packages

Resource & Organization vocabularies

Resource• used to be just ‘webcontent’ and various IMS specific types

defined elsewhere (QTI items etc.)

• now is an extensible vocabulary in a VDEX file

• can be extended by anyone

Organization• used to be just ‘hierarchical’

• extensible (e.g. use TopicMaps)

Providing alternative resources with different accessibility characteristics

What is new in IMS Content Packaging 1.2

Ipointer:

Where CP 1.2 is at

Public draft 1 was out IMS internal draft 2 documentation has been out

since February last year To be made public after testing and implementation

by IMS members more implementation test profiles: one lax and abstract, one production and strict

10

Where CP could go

There have been no CP 1.2 implementations, so: Possibility 1: mothball it until there is interest

Delays IMS QTI 2.1 No clean and clear CP documentation for implementors

Possibility 2: spin the new functions out in a new speclet

Ipointer and accessibility element live in their own namespace anyway

Clear road for intended ISO SC 36 standardisation plan

IEEE RAMLET; what it is

RAMLET

MPEG 21 DID

Atom

METSIMS CP

Atommapping

METSmapping

IMS CPmapping

MPEG 21 DIDmapping

12

Where RAMLET is at

Use case document out METS, IMS Content Packaging, IETF Atom and

MPEG 21 DID mapping complete Therefore: core ontology pretty stable Work on human readable description (scope notes)

almost done

13

Where RAMLET is heading

One library archive project in application One project to chart implementation options:

Dedicated library a la universal feed parser Traditional data warehousing Coordinated set of XSLTs Triple store / ontological knowledgebase etc.

Applicable to Question and Test formats?

14

Package transcoding service; the issue

Many IMS CP derivatives: SCORM 1.2 SCORM 2004 CP 1.1.2/3/4 Common Cartridge 1.0 / K12 /... NLN etc.

Many proprietary ... flavours: Blackboard WebCT etc.

15

Package transcoding service

16

Package transcoding service: requirements

Human, REST and SOAP interface All three? In that order?

Location National, institutional or both?

Standards IMS CP flavours first, RAMLET later?
