History IMS LIP (2001) UKLeaP allowed for PDP (drafted 2004) IMS ePortfolio took on PDP structures (2005) Perceived need for a simpler basis (2004? onwards) PIOP project (2008); LEAP2A is an emerging Atom-

based specification that is being developed and agreed with e-portfolio system developers

LEAP 2.0 (from 2007) comprises a broader, forward-looking, exploratory set of possibilities, based on Semantic Web concepts, for extending LEAP2A or similar, all based on same general ideas as LIP

3

Rationale Base on Semantic Web & Dublin Core

to give the simplest possible structures to reuse established practice to link to many current and future developments but need to shield from developers

Use familiar formats LEAP2A based on Atom, but could be others not necessarily fixed to any one XML schema information model similar to IMS LIP etc.

Able to merge readily with other information in other related schemas

4

The LEAP 2.0 vision From CETIS Portfolio SIG meeting, December 2006 No hierarchical structures for learner information Relationships basic, not peripheral Modular and extensible now "... aims to provide a sound basis for practical

interoperability between portfolio tools, and other tools dealing with the same kinds of information."

Simplicity in LEAP 2.0 LEAP 2.0 uses a very simple representation of portfolio

information Semantic Web RDF blobs and arrows (“triples”) A very few examples:

achievement – has evidence – resource (dissertation) activity (course) – supports – achievement (good grade) achievement – is evidence of – assertion (my statement) assertion – claims – ability (learning outcome of course) meeting – attended by – person

Does not build them into fixed complex structures because the patterns are changeable

A small corner ofblobs and arrows

course(activity)

outcome(ability)

achievement(good grade)

assertion(entry)

is evidence of

has outcome

supports

claims

personallydefined

resource(essay)

has evidence

LEAP2A – from December 2007 Portfolio InterOperability Prototyping (PIOP) project Wanted something that was definitely developer-friendly

uptake means everything for a standard developers are vital for implementation & uptake involve developers centrally from the outset

Chose to work with the Atom Syndication Format XML chosen by several others as an exchange format designed for blog feeds, but works for other things in Atom, everything is an entry suggested by several people for portfolio transfer

http://wiki.cetis.ac.uk/LEAP2A_specification is the specification to date, still under development

8

These are the Blobs Based on established usage

within partner portfolio systems

More have been sketched out in LEAP 2.0 for future consideration

Entry is used as itself for any general pieces of writing

Graceful degradation “plan” includes goal

LEAP2A types of information entry

ability achievement activity

meeting person resource selection

plan

9

LEAP2A relationships & inverses relation

reflects on has part has ordered part supports has evidence has agenda has outcome attended by has reply author (no inverse)

(inverse ones) reflected on by is part of is ordered part of supported by is evidence of is agenda of is outcome of attends in reply to

more in LEAP 2.0 for future consideration

10

Information about entries Entries have authors

Atom allows plain text name, e-mail, URI in LEAP2A, URI can relate to separate person entry but we haven't yet decided how to cover personal details

Records created, modified at certain times Achievements each have one date of achievement Plans each have one target date of completion Activities, meetings have start and end dates Things happen in locations These things are recorded “literally”

rather than by a relationship to another item “blob”

11

Abilities are of great interest (skill, competence, learning outcome, etc.)

People aim to acquire them through learning They are assessed People claim to have them Qualifications may be evidence of them

An ability itself needs to be an impersonal definition can be subject of goals can be subject of claims or assertions can be built up into skills frameworks

Ability is representable in LEAP ideally as an external definition, with just a link to it also possible to define within the portfolio information itself

12

PIOP project achievements 3 initial partners

University of Newcastle Pebble Learning (ex Wolverhampton) University of Nottingham

first version... agreed the LEAP2A spec to cover most existing needs demonstrated export of information (and import soon)

project now being extended to others carefully add in whatever else is necessary for them maintaining agreement of all who have been involved

13

LEAP future LEAP2A widening to encompass any portfolio tools Related systems are welcome to join in as well Develop LEAP2A transform to LEAP RDF

RDF will be the higher level of interoperability

Invite other specifications to develop transforms these to become alternatives to LEAP2A all still within the overall LEAP 2.0 vision e.g. might get small subset of HR-XML

Greater interoperability without coercion people can keep their own way of doing things

14

IMS ePortfolio possibilities Could keep separate, and do transform from IMS eP Coordination with IMS eP

Allow as alternative to IMS LIP within IMS eP Create complete mapping between IMS eP and LEAP2A

this may involve extending or modifying either then define transforms both ways at which point which is used no longer matters

Use LEAP 2.0 as basis of RDF version of IMS eP which would imply harmony at RDF even if not complete

mapping Collaborate with mapping both to HR-XML

15

Summary LEAP 2.0 offers a simple, powerful interoperability

framework based on Semantic Web concepts The PIOP project grounds it in well-used systems LEAP2A is its first developer-friendly XML specification,

based on Atom There is potential for coordination with IMS eP
