what we do
• research-oriented small enterprise (SME)– knowledge-intensive technology innovation
for agriculture and rural development– systems and services for agricultural
knowledge organization and delivery
• deployment and testing – in education & training, commerce, public
administration settings
data & information we work with
often distributed, unorganised• stats• gene banks• GIS data• blogs• journals• open archives• raw data• learning objects• …
at the end, its still like this…
two case studies
• agricultural research & innovation domain– experience from agINFRA
• biodiversity & natural history education– experience from Natural Europe
“We will promote research for food and agriculture, including research to adapt to, and mitigate climate change, and access to research results and technologies at national, regional and international levels.
We will reinvigorate national research systems and will share information and best practices.
We will improve access to knowledge.”Heads of State and Government, World Summit on Food Security, Rome,
November 2009

isolated access through portals
simplified version of problem
• interfaces to search/browse through metadata descriptions of agricultural learning resources
• backend: periodical harvesting of metadata from various providers – through OAI-PMH protocol/targets, as well as
human-facilitated ingestion/import– different metadata schemas/specs combined– indexing metadata element values to use for faceted
search/browse

More than a harvester:
Validation Service Repository Software Registry Service Harvester
25
Powered by
a validation service
26
• Tool to provide automatic validation of metadata instances against predefined application profiles, e.g. IEEE LOM
• Combines different sorts of validation techniques: XSD Schema is used for structural validation of xml metadata Schematron Rules are used for checking elements,
e.g. checking the presence of empty attribute fields
http://ariadne.cs.kuleuven.be/validationService/
a metadata repository service• Management of metadata records in an open and
scalable architecture• Open Standards & Specifications support
SQI , SPI, OAI-PMH, RSS
• Metadata schema support– IEEE LTSC LOM (by default)– Any schema with an XML binding
• Indexing with open source Apache Lucene framework• Open source license
27
a collection registry service
• A catalogue service: – Manages up to date information on metadata providers‐ ‐– Supports open standards & specifications (IEEE LOM, SQI , SPI, OAI-PMH, RSS,
…)– Facilitates interconnection of numerous providers– (Automatic discovery of new repositories)
28
a harvester service
29
• Incremental, scheduled harvesting• Supports SPI specification for publishing metadata into:
i. a specified component of the ARIADNE storage layer,ii. any other repository that has an SPI target on top of its
repository Integrated with other services in the infrastructure:

next challenges
1. Enhancing existing educational activities
• Introduce concept of educational pathways over collections & exhibitions through museum web sites (http://education.natural-europe.eu) for more museum visitors
• Cross-collection pathways for pan-European themes/topics of interest– e.g. World War I, Theory of Evolution
content for teacher activities
parents don’t (?) think activities
content for family activities
2. New technology services• Mobile, smartphone & tablet apps connected
dynamically with digital collections/Europeana API• Enriching technology platforms & tools used to
develop educational applications around cultural collections/exhibitions– educational platforms such as Learning Management
Systems (e.g. Blackboard), Course Management Systems (e.g. Moodle)
– cultural platforms such as virtual exhibition tools (e.g. Omeka)
