Health informatics — Document registry framework

ISO/TS 27790:2026 delivers an up-to-date, comprehensive framework for document registries supporting clinical and personalized health environments. The specification enables the reliable transmission, storage, and retrieval of all kinds of health documents across distributed organizations—paving the way for secure, scalable health information exchange (HIE).

Key content includes:

• Support for standards-based document types (HL7 CDA, FHIR, DICOM)
• Reference architectures leveraging IHE XDS, IHE MHD, and MHDS profiles
• Mechanisms for federation and cross-community document registration
• Guidance for metadata management and semantic interoperability

Healthcare providers, IT vendors, policymakers, and architects aiming for seamless EHR integration and patient data sharing must familiarize themselves with this specification. Adoption leads to improved patient safety, more responsive care, and better privacy safeguarding.

Major changes from the previous edition:

• Expanded coverage of mobile health document sharing
• Updated architectural models supporting distributed and federated registries
• Alignment with recent IHE interoperability developments

Key highlights:

• Framework agnostic to specific document standards—support for diverse health data
• Emphasis on cross-enterprise access, security, and privacy
• Bridges gaps between fragmented health IT systems

ISO/TS 23516:2026 – Blockchain and DLT Interoperability Framework

Blockchain and distributed ledger technology — Interoperability framework

ISO/TS 23516:2026 responds to the growing demand for interoperability across blockchain and distributed ledger technology (DLT) systems. This technical specification provides a framework for enabling seamless interactions between decentralized networks as well as connections with traditional (non-DLT) IT systems.

Core elements:

• Defines interoperability modes, scenarios, and solutions (e.g., oracles, gateways, node proxies)
• Identifies architectural facets: transport, syntactic/semantic data, behavioral and policy layers
• Addresses synchronization, asset transfer, and trust/confidentiality requirements
• Highlights governance, legal, and implementation considerations for cross-ledger solutions

Target audiences are DLT architects, IT strategists, fintech solution providers, and large organizations integrating blockchain into enterprise workflows. The framework helps to avoid technological lock-in and supports compliance with cross-border regulations.

Industry Impact & Compliance

These five standards will have substantial ramifications for organizations operating within the Information Technology and Office Equipment sector. With the march toward greater interoperability, transparency, and digital trust, early adoption will help organizations:

• Safeguard against security threats and compliance risks
• Ensure true cross-platform and cross-domain compatibility
• Simplify procurement by selecting certified, standards-aligned products
• Streamline development and integration cycles
• Foster global access and user confidence

Meeting these standards may be required by customers, regulators, or procurement processes. Transition periods typically require an early audit of current systems and a phased compliance plan, especially for security and health informatics standards. Non-compliance exposes organizations to increased risk, higher integration costs, and potential market exclusion.

Technical Insights

Many of these standards share common elements that facilitate their implementation:

• Modular structure: Built-in flexibility for partial adoption and specialization
• API-driven interoperability: APIs are highlighted in both geospatial and health informatics domains, prioritizing automation and machine-to-machine integration
• Assurance packages: Standard profiles (like EAL/CAP in FprEN ISO 15408-5) make it easier for organizations to communicate and evaluate security claims
• Registry and federation models: Several standards, such as ISO/TS 27790, are built on federated architectures, supporting distributed data environments
• Governance and semantic clarity: Clear separation between syntactic and semantic requirements, especially in blockchain/DLT and operating system specifications

Best practices for organizations include:

1. Mapping internal technology stacks to standard requirements
2. Engaging in pilot projects to test interoperability and compliance
3. Leveraging existing certified libraries, middleware, or health IT infrastructure
4. Regularly reviewing standards updates and training teams
5. Participating in industry forums or working groups to stay ahead of compliance trends

Testing and certification are crucial, particularly for operating systems (POSIX), security (Common Criteria), and integration-heavy domains like health informatics or DLT solutions. Early engagement with accredited labs and leveraging conformance classes or validation profiles speeds up the assessment process.
