• Share common understanding of the structure of information - Among people- Among systems/databases- Among people & systems/databases
• Provide consistency & reduce variability• Enable reuse of domain knowledge• Avoid re-inventing the wheel• Enable interoperability
Needs a Thesaurus

Existing Thesauri
![Page 10: Global agricultural Concept Scheme (GACS)](https://reader036.fdocuments.net/reader036/viewer/2022070301/54640656b4af9f5d3f8b47d5/html5/thumbnails/10.jpg)
We have some common beliefs
● We serve consumers of agricultural scientific knowledge
● We want to help them better navigate to and understand content
● We recognise the concept of global public goods and the value of open access & open data
● We have identified the need for a unified agricultural language system to support describing open data
Why GACS?

● G8 Conference on Open Data in Agriculture & Nutrition● In the age of open data we need common semantics to
describe data thus enabling linking different types of information & data
● We each manage an agricultural thesaurus: AGROVOC, NAL Thesaurus, CAB Thesaurus
● These three thesauri meet the needs of their parent organizations, but they have differences
We have some common challenges
Why GACS?

Why GACS?
We share some common knowledge

What?
Global Agriculture Concept Scheme GACS …
● A global unified agricultural language system● Address the differences and builds alignments between
AGROVOC, CABT and NALT● Public● Open (and moving to Open Data)● Collaborative (CABI, NAL, FAO)● Extensible (scope and partners)● An integrated offering● A working model (a bit more than a Proof of Concept?)
![Page 15: Global agricultural Concept Scheme (GACS)](https://reader036.fdocuments.net/reader036/viewer/2022070301/54640656b4af9f5d3f8b47d5/html5/thumbnails/15.jpg)
What?
GACS aspires to …
● Be owned and maintained by a consortium?● Bring economies of scale to partners and users● Avoid duplication of effort in new organisations moving
to open data environments● Improve efficiency of information and data management
in the long term● Improve the discoverability of information and data to
the benefit of farmers, researchers and policy makers

How?● Signed agreement between CABI, FAO, NAL to work together
to develop GACS, covering● Options for alignment● Technical Approach● Governance● Resources & Milestones
● Commission independent consultants to review existing thesauri and host organisation workflows and business needs
● Host and participate in workshops, working closely with policy makers
● This is what we hope to help start to answer here

Thank You

Questions?
● We are proposing an approach to address a need for a unified agricultural language system. Is this a real need? Will this workshop validate the need?Is this a useful approach? Is this an important development?
● At the moment there are three organisations involved and three thesauri. Which organisations are missing? Which vocabularies/thesauri are missing? Is it important that they are included in this ‘proof of concept’ stage. What would the nature of their participation be?
● Who would be the main users of GACS? Do we have enough ‘use cases’ to help people understand the utility of GACS?
● We will need to address the governance of GACS. What sort of models would work? What innovative solutions for governance would be possible?
● Have we missed anything? Are there alternatives?

Conclusions of the meeting?
● There is a need for GACS, this approach is important/essential, and although there may be other partners at this moment we want to scope out and implement a first phase.
