Traditional document-based message exchange is only one way of integrating data across supply chains. A number of fast growing alternatives are emerging.
All of these emerging technologies depend on common semantics in order to achieve scalability. But the semantics are managed as web vocabularies where each term has a specific meaning and can be composed dynamically in any order. In this world, the dictionary is more important than the document. The most popular syntax for publishing and managing these semantic dictionaries in JSON-LD. There are already a number of very important web vocabularies in use today.
Even the W3C has started publishing a supply chain traceability vocabulary to support their DID/VC work for real implementations of verifiable credentials in the supply chain – see the specification here https://w3c-ccg.github.io/traceability-vocab/ and the actual vocabulary here https://w3c-ccg.github.io/traceability-vocab/contexts/traceability-v1.jsonld
UN/CEFACT has perhaps the world’s most mature supply chain vocabulary (CCL and RDMs) and also an outstanding and trusted brand as a standards authority. But we do not publish our semantics in a usable way for modern web use cases. We risk losing relevance as a standards authority if we continue to focus only on document standards and do not support more modern technologies such as APIs, IoTs, and VCs. Therefore, the purpose of this project is to catch up with other semantic publishers and re-establish UN/CEFACT as the highest quality and authoritative publisher of supply chain semantic standards by publishing a UN/CEFACT JSON-LD vocabulary that includes all classes, properties, and code sets.
This project will deliver a high quality JSON-LD vocabulary published to a well-known unece domain and maintained throughout the ongoing development of the CCL, RDMs, and code lists. The vocabulary will be both human readable and machine readable and will support the international community in the development of interoperable APIs, IoT streams, and Verifiable Credentials. In order to support that outcome, the project will deliver • A technical specification that describes the JSON-LD structure and architecture. This work is already 90% completed as a technical guidance note from the RDM2API project – please refer to “draft-rdm2api-json-ld-ndr-docx at https://uncefact.unece.org/pages/viewpage.action?pageId=43384856 • A human and machine readable JSON-LD vocabulary on a unece web domain. This works is already 90% completed and a draft vocabulary is available at https://service.unece.org/trade/uncefact/vocabulary/uncefact/ (human readable) and https://service.unece.org/trade/uncefact/vocabulary/uncefact.jsonld (machine readable) • A publishing mechanism that allows the secretariat to continue to easily update the vocabulary as CCL, RDM, and code list changes happen. |

Membership is open to UN/CEFACT experts with broad knowledge in the area of: XML message design and related activities In addition, Heads of Delegations may invite technical experts from their constituency to participate in the work. Experts are expected to contribute to the work based solely on their expertise and to comply with the UN/CEFACT Code of Conduct and Ethics and the policy on Intellectual Property Rights. |
The geographical focus of the project is global. |
• RDM2API-JSON-LD Vocabulary Guidelines – a deliverable from the RDM2API project can be re-used as the basis for the technical specification. • https://service.unece.org/trade/uncefact/vocabulary/uncefact/ - existing published draft vocabulary can be re-used as the basis for a final vocabulary publishing framework. • UNCEFACT Projects (unece.org) – Application Programming Interface Technical Specification (API TechSpec) |
