Abstract
|
The AgriTrust framework resolves the agricultural data paradox by integrating multi-stakeholder governance with a semantic, blockchain-agnostic architecture to automate trusted data sharing for regulatory compliance and supply chain transparency.

Competency question
|
A. Governance & Provenance CQ1 (Ownership): Which :DataProducer owns a given :Asset? CQ2 (Authorization): Who (:DataConsumer) is authorized by a :DataContract to access the data for a specific :Asset? CQ3 (Provenance): What :Process entities transformed a given :Asset, and what were its inputs and outputs? B. Traceability & Compliance 4. CQ4 (EUDR Evidence): For a given :Token representing a coffee batch, what is the geographic location (geo:asWKT) of the farm that owns it, and what sustainability :Certificate does that farm hold? 5. CQ5 (Batch History): List all :IndividualAsset (e.g., cattle) that were inputs to a specific :CollectiveAsset (e.g., a beef batch). 6. CQ6 (Active Certificates): Which :Asset entities currently have a valid (not expired) :Certificate of type "Organic"? C. Interoperability & Operations 7. CQ7 (Cross-Chain Reference): Does a given :CrossChainToken have a registered counterpart on another :BlockchainProvider? 8. CQ8 (Governed Metrics): What :EfficiencyMetric (e.g., carbon footprint) values are linked to a farm's operations, and which :DataContract governs access to them?

Description*
|
New regulations, such as the EU Unrestricted Deforestation Regulation (EUDR), make verifiable agricultural data (AgData) essential for global trade. However, its value is compromised by a widespread "AgData Paradox," characterized by distrust and fragmentation. To address this problem, we present AgriTrust, a federated semantic governance framework that automates and governs data sharing. Its key methodological innovation lies in the deep integration of a multi-sectorial governance model with a semantic digital layer, implemented through the AgriTrust Ontology (an OWL ontology for tokenization and traceability) and a multi-vendor, blockchain-agnostic architecture that avoids single-vendor dependence.
