How can we build an open and scalable learning infrastructure
for food safety

Multi-Donor Trust Fund (MDTF) being established to raise at least $45,000,000 for implementation of a Roadmap and 5-year workplan
aim: train small food producers, around the world, using blended approaches

• may aim higher than a single GFSP learning platform – cannot generalize something that requires a focused, regional approach
• rather develop a GFSP Learning Infrastructure including (among others) – Educational Offerings Aggregator Services– Curriculum Support, Registry & Alignment Services– GFSP Learning Portal (main front end)– GFSP Learning Widgets/apps (to be integrated in web
sites, offered through smartphones/tablets, etc)
evolving the concept
could look like this
• back end technology infrastructure– ingest, harvest, aggregate course and OER
metadata from existing or new (e.g. legacy) learning platforms and OER collections– tools to allow course and OER providers to
align/map their metadata & classifications to the GFSP ones
Educational Offerings Aggregator
• representation of GFSP curriculum in interoperable format (using learning outcomes, competences)– tools to allow other course providers to register and
express/map their curricula to the GFSP curriculum– tools to facilitate the generation of multilingual versions
of the curricula descriptions– generation of transformable curricula representations to
allow users to browse using preferred curicullum format
Curriculum Registry & Alignment
• main front-end to present project and allow users to find information in the aggregated sources– various modalities (visual, device, thematic,
geographical, industry, …) for search & discovery of courses and OER –multilingual interfaces and metadata facilitated
by automatic translation engines
GFSP Learning Portal
• search/discovery interfaces and mechanisms that can be embedded in other web sites and portals (widget-like or search pages in sites)
• mobile apps for various operational systems (iOS, Android, Windows 8)
• back-end engine to allow straightforward generation of adaptable versions of both (thematic, industry, geographical, linguistic, …)
GFSP Learning Widgets/Apps
important distinction
• such a learning infrastructure is heavily dependent on the back-end layers
• it is important to be able to power existing applications and services
• the centralised portal mainly serves as demonstrator
• will really change something if it provides a wealth of resources around each topic
a case study
• regional meat producer in Paraguay– example scenario: exploring how their company
can start selling packaged cooked ham to an international food distribution company
• product of high quality one, made from pure pork ham– let us assume that they would like to find out more
about the food safety standards of cooked ham
this is why#3

what’s really happening behind
DOMAIN EXPERTS
publish & evolve vocabularies &
ontologies
CONTENT PROVIDER WITH CMS THAT SUPPORTS OAI-PMH (e.g. FSKN compliant, ePrints, DSPACE,...)
CONTENT PROVIDER WITH CMS THAT DOES NOT SUPPORT OAI-PMH (e.g. Proprietary DB)
Metadata export in proprietary
format & provides mapping
Ingestion in compliant tool
CONTENT PROVIDER WITH UNORGANISED COLLECTION(e.g. Listed at Web site or in DVD-ROM)
Chooses compliant tool

typical problems
a. metadata authoring/creationb. metadata assurance/validationc. metadata values/vocabulariesd. metadata multilingualitye. …lots more
36
a. authoring/creation
• metadata creation is a painful and costly process–automatic generation can help–high quality/accuracy/relevance
descriptions require human intervention
37
a. authoring/creation
38
b. assurance/validation
• good online services demand high quality (or at least not poor quality) description of content–someone needs to take the final decision
before something is published–especially relevant when content
development has been costly/labourous
39
b. assurance/validation
40
c. values/vocabularies• mappings and crosswalks among values and
vocabularies of different collections are crucial–usually manually defined and maintained–difficult to ensure that all applications will
publish and link their vocabularies–vocabulary bank management tend to become
too complex for the purpose that they serve
41
c. values/vocabularies
42
d. multilinguality• for multilingual contexts, everything
needs to become (and be maintained) multilingual–metadata values and labels– interface labels for various systems
• automatic translation helps but usually produces rather rough/poor translations
43
d. multilinguality

challenges in semantics
describing course offerings
• what I am describing is different to what you are describing…–…but there are so many similar things!

more issues…
• old-fashioned legacy systems still used in such traditional settings– terms like “OER” and “MOOC” sound like science fiction
• novel technologies such as semantic stores and ontology editing/managing environments are not user-friendly and proven– especially for such technology-ignorant users
• very rich semantics to be represented, handled and exploited; but we are not there yet
