Interoperability
If e-portfolio systems are to be used for lifelong learning, they should interoperate
Several specifications have been suggested
How can an e-portfolio system be built or made to be interoperable?
![Page 3: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/3.jpg)
Outline agenda menu
Do the definitions make sense? Do we share understanding of the items? What is interoperability? How items are represented by specs Europass instruments E-portfolio systems architecture Interoperable skills and competences
![Page 4: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/4.jpg)
E-portfolio items (1)
Achievements qualifications; certificates; awards; prizes;
etc. Products
works; things created, tended, managed Competencies (by whatever name)
knowledge; skills; attitudes achievements/products can be evidence
![Page 5: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/5.jpg)
E-portfolio items (2)
Goals a sense of direction as in action planning
Activities past: as record to present and reflect on future planned: as part of action planning
Evaluations (formal) of activities or products
![Page 6: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/6.jpg)
E-portfolio items (3)
Interests what personally motivates, including values
Assertions by self or others, testimonials, free format
evaluation by others Reflections
as part of PDP; self-evaluation
![Page 7: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/7.jpg)
E-portfolio items (4)
Organisations (reference) point of reference for several things
Affiliations details of relationship with organisations
Other people of significance (reference) mentors; friends; people that wrote
assertions
![Page 8: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/8.jpg)
E-portfolio items (5)
Identification names, addresses, photos, date of birth…
Relationships many highly significant between items
metadata not an item in itself, but a record of: rights
over any item; dates of creation, revision
![Page 9: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/9.jpg)
E-portfolio items review
Is there anything that doesn’t fit in those?
Do those categories distinguish properly? between things of different form/structure
How do these relate to lifelong learning?
![Page 10: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/10.jpg)
What is interoperability?
Portability of e-portfolio records; OR Different systems concurrently offering
and using related services To be useful, interoperability
specifications must be based on real practice
What are your scenarios? What services are implied?
![Page 11: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/11.jpg)
Semantic interoperability
Can the item of information in one context be meaningfully interpreted in another? think of particular PDP scenarios…
Role of type vocabularies to distinguish semantically different things
with the same or similar structure Could items with types form a sufficient
basis for making useful distinctions?
![Page 12: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/12.jpg)
Current specifications
IMS LIP 2001: large and complex
UKLeaP (BS 8788) 2004/5 attempting to make LIP usable
IMS ePortfolio draft 2004, final 2005
HR-XML

What do we want of a standard?
Various trade-offs Simple – complex XML – RDF well-defined – flexible monolithic – segmented (“speclets”) early (untested) – late (tested)
Development / revision: easy or hard?

Europass issues
Europass representation challenges Who is working with Europass
instruments? How and why? May there be a future need to generate
the Europass instruments from an e-portfolio system?
![Page 16: EDEN 2005 Annual Conference, 20.-23.6.2005, Helsinki, Finland Insights into electronic portfolio interoperability Simon Grant Independent consultant Information.](https://reader036.fdocuments.us/reader036/viewer/2022082417/5697bf711a28abf838c7dd6a/html5/thumbnails/16.jpg)
E-portfolio systems architecture
Distributed nature of item storage items held by originating institutions?
Need for aggregation/distribution future concept “PIADS”: personal information
aggregation and distribution service See WS4RL

Skills interoperability
What happens when institutions describe skills in different ways? evidence here does not connect over there
But uniform standards not feasible Need a “meta-framework” for skills
enable relationships across frameworks http://www.elframework.org/projects/spws

Concluding comments?
Is interoperability feasible now, or when? Transfer or concurrent use? What stands in its way? Is the fundamental approach sound? Or is there a better way? Can you take this forward?
