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
![Page 6: Content Specs Update](https://reader036.vdocument.in/reader036/viewer/2022062404/55496ea3b4c905dd558b513a/html5/thumbnails/6.jpg)
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)

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
![Page 10: Content Specs Update](https://reader036.vdocument.in/reader036/viewer/2022062404/55496ea3b4c905dd558b513a/html5/thumbnails/10.jpg)

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
![Page 12: Content Specs Update](https://reader036.vdocument.in/reader036/viewer/2022062404/55496ea3b4c905dd558b513a/html5/thumbnails/12.jpg)
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

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?

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.

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?
