“…We contributed to the OASIS ontology [10][11][12]22], which applies the behaviouristic approach to deliver a general representation system and a communication protocol for agents and their interactions. Therefore, OASIS can be profitably leveraged here, so that commercial participants and their commitments are semantically described as agents by means of the actions they can perform through their commercial activities, including the applicable payment options, provision methods, and supply chains.…”

“…In [22], the authors propose a first version of OASIS, an ontology to represent agents and their commitments using the behaviouristic approach adopted in this work, together with a home automation assistant based on it, called PROF-ONTO. The approach used in [22] also represents a first foundational contribution to the use of Semantic Web technologies to define a transparent communication protocol among agents.…”

Electronic commerce and finance are progressively supporting and including decentralized, shared and public ledgers such as the blockchain. This is reshaping traditional commercial activities by advancing them towards Decentralized Finance (DeFi) and Commerce 3.0, thereby supporting the latter’s potential to outpace the hurdles of central authority controllers and lawgivers. The quantity and entropy of the information that must be sought and managed to become active participants in such a relentlessly evolving scenario are increasing at a steady pace. For example, that information comprises asset or service description, general rules of the game, and specific technologies involved for decentralization. Moreover, the relevant information ought to be shared among innumerable and heterogeneous stakeholders, such as producers, buyers, digital identity providers, valuation services, and shipment services, to just name a few. A clear semantic representation of such a complex and multifaceted blockchain-based e-Commerce ecosystem would contribute dramatically to make it more usable, namely more automatically accessible to virtually anyone wanting to play the role of a stakeholder, thereby reducing programmers’ effort. However, we feel that reaching that goal still requires substantial effort in the tailoring of Semantic Web technologies, hence this article sets out on such a route and advances a stack of OWL 2 ontologies for the semantic description of decentralized e-commerce. The stack includes a number of relevant features, ranging from the applicable stakeholders through the supply chain of the offerings for an asset, up to the Ethereum blockchain, its tokens and smart contracts. Ontologies are defined by taking a behaviouristic approach to represent the various participants as agents in terms of their actions, inspired by the Theory of Agents and the related mentalistic notions. The stack is validated through appropriate metrics and SPARQL queries implementing suitable competency questions, then demonstrated through the representation of a real world use case, namely, the iExec marketplace.

“…Finally, the paper Ontological Smart Contracts in OASIS [1] defines the concept of Ontological Smart Contract extending the OASIS ontology for agents, systems, and integration of services [11]. The proposed ontology defines the concept of a smart contract as an entity to define agreements between agents and specify their terms, independently from the specific blockchain implementation.…”

“…In this paper, we discuss how the OASIS ontology can support the modelling of ontological smart contracts considering different blockchain technologies, and how it can be extended and leveraged to model business agreements in different domains. Indeed, the usage of the OASIS ontology is exemplified in [1] considering a trading agent selling stocks and the Ethereum platform, while, in Section 5, we consider agreements in the transportation domain implemented through the Hyperledger Fabric API 5 .…”

“…The developed Ride2Rail Ontology for Agreements leverages the concept of Ontological Smart Contract defined in the OASIS ontology [1] and investigates how it can be extended to model the semantic of business agreements. Although we focused our work on the transportation domain, the proposed approach can be generalised to model ontological smart contracts in different domains.…”

The blockchain technology provides integrity and reliability of the information, thus offering a suitable solution to guarantee trustability in a multi-stakeholder scenario that involves actors defining business agreements. The Ride2Rail project investigated the use of the blockchain to record as smart contracts the agreements between different stakeholders defined in a multimodal transportation domain. Modelling an ontology to represent the smart contracts enables the possibility of having a machine-readable and interoperable representation of the agreements. On one hand, the underlying blockchain ensures trust in the execution of the contracts, on the other hand, their ontological representation facilitates the retrieval of information within the ecosystem. The paper describes the development of the Ride2Rail Ontology for Agreements to showcase how the concept of an ontological smart contract, defined in the OASIS ontology, can be applied to a specific domain. The usage of the designed ontology is discussed by describing the modelling as ontological smart contracts of business agreements defined in a ride-sharing scenario.
