OPC UA Core Funding

OpenOpcUa provides a full, production-grade OPC UA implementation.
OPC UA Core Funding sustains the long-term evolution of the middleware core: runtime integrity, specification tracking, certification alignment, and architecture continuity.

Why Core Funding?

Industrial OPC UA deployments require more than code. They require long-term stability, controlled evolution, and strict alignment with IEC 62541 and Companion Specifications.
OpenOpcUa is not an SDK. It is an implementation-first OPC UA middleware core.
Core Funding has been in place for more than a decade to ensure this core remains sustainable and industrial-grade.

  • ✔ Long-term runtime stability and backward compatibility
  • ✔ Continuous IEC 62541 tracking and integration strategy
  • ✔ Security hardening and compliance evolution
  • ✔ NodeSet-driven modeling execution (Model + Deployment NodeSets loaded at runtime)
  • ✔ Controlled modular extensibility (VPI / VFI) without breaking integrity

What Core Funding Supports

Core Funding directly sustains the technical foundation — not marketing activities.

Runtime core

  • OOUACoreServer evolution
  • Performance, determinism, robustness
  • Security & sessions hardening

Specifications & alignment

  • IEC 62541 evolution tracking
  • Companion Specifications integration strategy
  • Architectural compliance over time

NodeSet-driven execution

  • Model NodeSets (types) + Deployment NodeSets (instances)
  • Runtime loading (no compile step)
  • Large-scale AddressSpace materialization

Unlike short-term project-based development, OpenOpcUa is built as a durable middleware core.
Sustaining that core requires structured funding.

What Funding Supports

Funding directly contributes to:

Runtime Evolution

  • Maintenance and improvement of the OOUACoreServer
  • Performance optimization
  • Security hardening
  • Compliance alignment with new OPC UA specification revisions

Certification & Specification Tracking

  • Monitoring and implementation of OPC Foundation updates
  • Alignment with companion specifications
  • Architectural adjustments required by standards evolution

NodeSet-Driven Modeling Infrastructure

  • Improvements to Model NodeSet and Deployment NodeSet handling
  • Runtime materialization mechanisms
  • Industrial scalability

Long-Term Architectural Stability

  • Preservation of the implementation-first philosophy
  • Controlled extensibility via VPI / VFI
  • Lua-based evolutive mechanisms within the runtime core

Funding does not sponsor marketing.
It sustains the technical core.

Governance and Technical Direction

OpenOpcUa technical direction remains architecture-driven.
Core funding participants:

  • Gain visibility into the roadmap
  • Contribute to strategic technical priorities
  • Participate in architectural discussions

However:

  • The runtime integrity is preserved
  • The industrial coherence of the middleware remains central
  • Short-term feature pressure does not override architectural stability

This ensures long-term industrial viability.

Who Should Consider Funding

The Core Funding Program is intended for:

  • Industrial system integrators
  • Software vendors embedding OPC UA
  • Technology providers relying on OPC UA runtime stability
  • Organizations seeking long-term OPC UA middleware alignment

If your product or infrastructure depends on a stable OPC UA core, funding its evolution is a strategic decision.

Funding Structure

Funding is structured and transparent.
Participation may include:

  • Annual funding agreements
  • Targeted development sponsorship
  • Strategic roadmap contributions

Details are discussed directly to ensure alignment with industrial objectives.

Relationship with the Ecosystem

The Core Funding Program is distinct from ecosystem participation.

  • Technical collaboration and integration → see Join the OpenOpcUa Ecosystem
  • Structured financial participation → Core Funding Program

Both contribute to the same objective:
A durable, industrial-grade OPC UA middleware foundation.

Governance and Technical Integrity

Funding sustains evolution — it does not compromise architectural integrity.
OpenOpcUa remains architecture-driven: extensibility is controlled, runtime integrity is preserved, and long-term coherence is prioritized over short-term feature pressure.

Core Funding Participation Level

OpenOpcUa Core Funding is structured through defined participation levels.
Each level corresponds to a clearly defined scope of usage rights, support duration, and onboarding intensity.

FAQ

Is Core Funding required to use OpenOpcUa?

No. OpenOpcUa binaries are available for evaluation and integration. Core Funding supports long-term sustainability, industrial alignment, and structured guidance.

Where are the Funding Levels (Green/Blue/Bronze/Silver/Titanium/Gold)?

Funding Levels are presented on the Join Us page, including scope and payment options.

Does the sponsorship include OPC UA information modeling support?

Yes. Sponsors receive guidance on OPC UA information modeling, Companion Specification integration and domain-specific model design to ensure semantic consistency and maintainability.

Who provides operational technical support?

OpenOpcUa is a technical organization. Operational support, contractual arrangements and invoicing related to technical sponsorship are managed by 4CE Industry.

Can the sponsorship support Companion Specification integration?

Yes. The program supports the integration and adaptation of official OPC Foundation Companion Specifications within structured industrial architectures.

Is the OPC UA server compliant with IEC 62541?

Yes. OOUAMiddleware is built on a certified and strictly aligned IEC 62541 implementation designed for industrial interoperability and long-term robustness.

Does funding influence architectural direction?

Funding supports evolution priorities but does not compromise runtime integrity. OpenOpcUa remains architecture-driven and compliance-focused.
