Data Exchange

RaulWalter’s data exchange solutions enable secure, standards-based, and fully auditable data flows between organisations and national systems.

Our experience spans X-Road–type data exchange platforms, API-based integrations, and PKI-protected service-to-service communication.

We support complete architecture, security, and interface solutions — from service package modelling and schema standardisation to logging, monitoring, load tolerance, and operational procedures.

We have helped build data exchange layers that underpin critical national registries, tax and social services, and numerous international digital services. The result is an ecosystem where data moves between the correct parties in a controlled, secure, and highly reliable manner.

Data Exchange Architecture & Platform Design

We design national and organisational data exchange architectures that define how systems connect, communicate, and scale. This includes selecting and designing exchange models (X-Road–type platforms, federated APIs, hybrid approaches), defining trust boundaries, and ensuring long-term extensibility. Architectures are designed for high availability, legal clarity, and operational resilience.

Service Package Modelling & Interface Standardisation

We define service packages, schemas, and interface contracts that make data exchange predictable and interoperable. This includes harmonising data models, versioning rules, semantic definitions, and error handling. Standardised interfaces ensure that services can be reused, integrated, and evolved without breaking dependent systems.

Security, Trust & PKI-Based Communication

We implement strong security controls for service-to-service communication, including mutual authentication, encryption, and certificate-based trust. This includes PKI design, key management, certificate lifecycle processes, and alignment with national and international trust frameworks. Security is embedded into the exchange layer rather than bolted on later.

Logging, Monitoring & Auditability

We design and implement comprehensive logging and monitoring that makes data exchange observable and auditable. This includes transaction logging, integrity protection, traceability, and monitoring for availability and performance. The result is an exchange layer that supports compliance, incident response, and operational assurance.

Operational Governance & Exchange Enablement

We support the operationalisation of data exchange platforms through governance models, onboarding procedures, and operational documentation. This includes defining roles, responsibilities, service onboarding processes, and change management rules. Exchange ecosystems are built to function reliably across multiple organisations over time.
