- Designing a Taxonomy of Decentralised Identifier / Identity Terms for ISO/TC307
Blockchain and Distributed Ledger Technologies
As European SMEs are subject to stronger regulation (e.g. eIDAS, GDPR, Copyright), harmonising terminologies, taxonomies and architectures in worldwide standards is key to avoid their fragmentation between international (e.g. ISO, W3C), European (e.g. CEN-CENELEC) and national standards (e.g. UNE, AFNOR). Harmonising decentralised identifier and identity terminologies and taxonomies is key at ISO/TC307 and CEN-CENELEC/JTC19 before they are derived in European regulation (initially eIDAS2) and infrastructures (e.g. EBSI). All European SMEs will take advantage of such harmonisation.

Blockchain and Distributed Ledger Technologies
In the medium term, this contribution is an opportunity to reinforce the cohesion and collaboration between European experts from ISO/TC307, mostly independent experts representing SMEs, and to achieve efficient progress within a short timeframe.
The revision of ISO/TS 23258 Blockchain and DLT Taxonomy & Ontology is also an opportunity to adopt concepts from the European landscape reports, e.g. “Report of TWG Ontologies: Landscape of Ontologies Standards” (2023) by StandICT.
In the long term, as European SMEs face increasing regulation (e.g. GDPR, eIDAS 2, Data Act, CRA, MiCA, DORA, NIS2, AI Act) and new terminology (e.g. “real-world asset”, “layer 2 solution”), revising vocabularies, taxonomies, ontologies and reference architectures in worldwide standards is key to keeping regulation and information up to date.
- Revision of existing work items
-
This contribution addresses the revision of ISO/TS 23258 (Blockchain & Distributed Ledger Technologies - Taxonomy & Ontology) that was first released in 2021. I am the project leader of ISO/TS 23258 at ISO/TC307/WG1.
Value of Research
The objective of this contribution was to design a taxonomy of decentralised identifier and identity terms for further integration into ISO/TC307 works developed by AHG5 and JWG4.
My fellowship was key to address the gap between worldwide blockchain and DLT standards in the fields of identifier and identity management, especially between ISO/TC307, ITU-T and W3C while including some European-led reference documents (i.e. EBSI, eSSIF-Lab and INATBA glossaries).
