ISO/TR 6277:2025Blockchain and distributed ledger technologies (DLT) — Data flow models for blockchain and DLT use cases

This document uses a set of models that describe the flows of different types of data between distributed ledger technologies (DLT) and related systems, as well as between different DLT nodes.

It provides a descriptive analysis of data flows in the development of use cases, as well as the basis for understanding the characteristics of DLT data flows, to support DLT application design and system analysis.

The models referenced are in accordance with ISO 23257 and the use case analysis approach provided in ISO/TR 3242.

The proposed standard will set the Reference Data (Model/Schema) to describe and identify carbon credit projects and units. The standard supports participants, regulators and infrastructure providers in international carbon credit markets by facilitating exchange of information on the assets being created, transacted, and tracked. The scope of this proposal includes: - Defining a common carbon credit data taxonomy to help harmonise data fields, formats, and models across different carbon credit registries maintained by carbon crediting programs or other parties; - Considerations for adapting this data model for use in financial markets. The scope of this proposal excludes: - Setting thresholds or otherwise evaluating carbon credit quality; - Standardizing processes for how carbon credits are created, measured, verified or traded - Guidance on who can issue, trade or purchase carbon credits.

This standard defines the key Minimal Interoperability Mechanisms (MIMs) underpinning smart city platforms and Local Digital Twins, following the methodology described in ITU-T Y.4505 and aligned with the AI-based EU LDT Reference Architecture. It provides normative specifications compatible with CitiVerse requirements for :

• MIM 1: Context Information Management - Standardized APIs and protocols (starting from NGSI-LD) for accessing, updating, and subscribing to context data from diverse sources, ensuring semantic interoperability and real-time data integration across urban platforms.

• MIM 2: Data Models - Common, reusable, and extensible data models (starting from SAREF) that enable consistent representation and exchange of information across domains and systems, supporting discoverability and harmonization of data structures.

• MIM 7: Places - Mechanisms for the standardized representation, identification, and management of geospatial entities (places), enabling location-based services, advanced geospatial queries, and cross-domain referencing of physical and virtual places,with alignment to INSPIRE where applicable.

The standard details technical requirements, interfaces, and conformance criteria for each MIM, ensuring interoperability across platforms while supporting compliance with EU regulations including the Interoperable Europe Act. It builds on ongoing definition efforts of the MIMs framework within Living-in.EU and incorporates implementation experience from pioneer cities. 

ISO/IEC FDIS 29128-3 Information security, cybersecurity and privacy protection — Verification of cryptographic protocols Part 3: Evaluation methods and activities for protocol implementation verification

This document gives guidance on evaluating the implementation of a cryptographic protocol based on the framework provided in ISO/IEC 15408-4. This document specifies the required methods and activities to assess the conformance of a cryptographic protocol implementation to its ISO/IEC 29128-2 based formally verified protocol model. This document specifies assurance metrics for the integrated evaluation of both the cryptographic protocol and its implementation.

This document specifies accessibility requirements on information provision and communication in support services. This includes general information about the products and services including information on their accessibility. This document provides requirements on an accessible support service designed so that information and communication can be accessed, understood and used. Support services include but are not limited to help desks, call centres, technical support, and training services. It applies to support services that are provided digitally or face to face. NOTE 1 Where relay services are referred to in this document, relay services are a means to communicate in the provision of support services. NOTE 2 It includes support services that are provided directly and those that have been outsourced. It is applicable for all organisations of all sizes and across all sectors.

This document specifies user requirements for the accessibility of non-digital information related to products and services. This document describes test procedures and evaluation methodologies for non-digital information technical solutions. This document is applicable to the presentation of visual, tactile and auditory based non-digital information and instructions, including: - displayed on a product - displayed on the packaging or in the packaging of products - about the use of a product - about installation and maintenance, storage and disposal of products - about products used in the provision of services and about the functioning of the service - about air, bus, rail and waterborne passenger transport services - about consumer banking services. This document is intended for use by organisations that produce products and or provide services. This document does not apply to the presentation of information by ICT products and services, for instance displayed on a screen
