ActiveDB & AAS: Dynamic Digital Twins Based on the IDTA Standard

Digital twins have long been more than just a concept.
They are becoming the cornerstone of scalable, data-driven business models.

With the Asset Administration Shell (AAS), the IDTA has created a standard that defines how digital twins can be structured and exchanged.

ActiveDB goes a step further:
It fully supports the standard—and turns it into living digital twins that are actively integrated into processes.

After reading this article, you will know:

  • How ActiveDB supports the IDTA AAS standard and imports and exports compatible digital twins.
  • How this results in dynamic digital twins with bidirectional data, CRUD, and advanced features.
  • How companies can use digital twins that are both standards-compliant and operationally viable.

1.

The Standard: IDTA Defines AAS (Digital Twins)

The Standard: IDTA Defines Digital Twins

The IDTA clearly describes how a digital twin is structured:

  • Administrative shells (AAS) as the outer layer of an asset
  • Submodels for structuring data
  • Standardized interfaces for data exchange

The goal is clear:
Interoperability across system and organizational boundaries

However, in practice, it becomes apparent that:
The standard defines structure and data exchange — the platform enables operational use during ongoing operations.

2.

ActiveDB: From a static model to a dynamic digital twin

ActiveDB adopts the structure of the AAS—but expands it into an operational system.

As a result, a digital twin is not merely described, but:

  • Actively utilized
  • Updated bidirectionally
  • Integrated into processes

 

ActiveDB thus defines living digital twins.

3.

What else ActiveDB makes possible

Compared to a standard IDTA definition, ActiveDB offers advanced capabilities:

  • Bidirectional data
    flows instead of simple mapping
  • Full CRUD
    time series, and real-time(complete creation, reading, updating, and deletion of twin data)
  • Extended links
    for semantics and data exchange
    Actions and logic directly within the digital twin
  • Configuration and documentation
    in the same system

 

 

The result:
A digital twin evolves from a mere description into an active component of the system architecture.

This applies to AI as well.

4.

Full IDTA compatibility

ActiveDB remains fully compatible with the IDTA AAS standard:

  • AAS-compliant twins are accepted directly
  • Internally, they are standard ActiveDB objects
  • They can be exported in IDTA format at any time

This ensures:

  • Seamless integration with existing AAS systems
  • Compatibility with third-party applications
  • No reliance on proprietary formats

5.

More than just a repository: A complete AAS implementation

More than just a repository: A complete AAS implementation

ActiveDB implements not just individual components, but the entire infrastructure:

  • AAS Repository
  • AAS Registry
  • Submodel Repository
  • Additional interfaces such as MQTT, etc.

This creates a system in which living digital twins can be fully utilized.

6.

Conclusion: Standard + Extension = Real-world usability

The IDTA AAS lays the foundation for digital twins.
ActiveDB turns this into a system ready for real-world use.

Dynamic digital twins powered by ActiveDB are:

  • Standard-compliant
  • Interoperable
  • Extensible
  • Operationally usable

 

This transforms a data model into a true value driver for digital business models.

This helps companies avoid:

  • Data silos – data is scattered and cannot be used consistently
  • Point-to-point integrations – each interface increases complexity
  • Distributed logic – no central control

 

It’s not the technology that’s the limiting factor—it’s the architecture.
