# About contextualization

Contextualization is key to make your data more accessible, rapidly draw new insights from your data, and make your data do more.

The interactive contextualization tools in Cognite Data Fusion (CDF) let you combine machine learning, a powerful rules engine, and domain expertise to map resources from different source systems to each other in the CDF data model.

This way of connecting information allows you to build applications where you, for example, can click a component in a 3D model to see all the connected time series data or ask for all the pressure readings along a flow line.

The first part of contextualization is to ensure that each unique entity shares the same identifier in CDF, even if it has different IDs in the source systems. This step is mostly performed during the transformation stage when you shape and match incoming data and compare it with existing resources in your collection.

Reference architecture

The next step in the contextualization process is to associate entities with each other the same way they relate in the real world. For instance, an object inside a 3D model may have an ID that you can map to an asset, and a time series from an instrument monitoring system can have another ID that you can assign to the same asset.

Our contextualization tools help you build interactive P&IDs (Piping and Instrumentation Diagrams) from static PDF source files, and you can match entities to set up, automate and validate all your contextualization pipelines from your browser without having to write any code.
