What is Information Architecture?
Information architecture describes how information within an organisation is structured, exchanged, managed and used. It bridges the business architecture (processes, goals) and the application architecture (software and systems).
Information architecture ensures that the right information is available at the right time, in the right form and to the right person.
🧠 What does information architecture cover?
| Component | Description |
|---|---|
| Concept frameworks | Definitions of key terms (e.g. customer, permit, notification) |
| Data models | Structure of data (such as tables, entities, relationships, XML schemas) |
| Data flows | How and where information flows between processes, applications and supply chain partners |
| Metadata and classification | Description, source and quality of data |
| Standards and frameworks | Use of e.g. ZTC, RGBZ, StUF, IMRO, Linked Data |
🧱 Importance of information architecture
| Benefit | Explanation |
|---|---|
| Coherence and reuse | Data is captured once and used many times |
| Fewer errors | Through unambiguous definitions and structured storage |
| Better service delivery | Through faster and more reliable information provision |
| Interoperability | Essential for supply chain collaboration and inter-organisational integration |
| Insight and accountability | Supports audits, compliance and reporting |
🔄 Relation to other architectural layers
| Architecture layer | Linkage with information architecture |
|---|---|
| Business architecture | Provides the information requirements derived from processes and objectives |
| Application architecture | Uses data models and exposes data via interfaces |
| Technical architecture | Provides storage, integration platforms, databases, security |
🏛 Information architecture in government architectures
| Architecture | Information component |
|---|---|
| NORA | Concept frameworks, generic functions and data principles |
| GEMMA | RGBZ (case information), ZTC, data models for municipal domains |
| WILMA | Information models for water management, object data and monitoring |
| PETRA | Models such as IMRO, IMEV for spatial planning and energy |
| MARIJ | Central government data and exchange standards |
Information architecture is often the foundation for standards, data quality and data exchange.
🏭 Information architecture in an OT context
Information architecture is becoming increasingly important in Operational Technology (OT) too:
| OT application | Information aspect |
|---|---|
| Sensors and measurement data | Structuring telemetry: who, what, where, when? |
| SCADA and PLC data | Mapping of signals onto information models |
| OT-IT integration | Use of information models when forwarding data to dashboards or BI |
| Asset information management | Data about machines, maintenance, location, status |
Modelling and managing information from OT systems makes data both usable and reliable in broader decision-making.
🔐 Security and governance
- Governance ensures ownership, quality and lifecycle of data
- Privacy by Design requires well-structured data processing
- BIO and AVG impose requirements on data minimisation, logging and transparency
- Security by Design requires insight into which data flows where
📌 In summary
Information architecture ensures that data is not chaos but a valuable resource. It is the core of reliable, secure and reusable information provision — in both IT and OT environments.
