Use this contextualization tool to find, extract, and match tags on engineering diagrams and link them to an asset hierarchy or other resource types, such as files. You can approve or reject the results at any time. An engineering diagram with new tags has the status Pending approval. This status means that there are detected tags that need to be either approved or rejected to ensure that the interactive diagrams are accurate. For each engineering diagram, CDF shows the tag types it has detected:
  • Tag type Diagrams: Tags to other engineering diagrams.
  • Tag type Assets: Tags to other assets in CDF.
  • Tag type Unlinked: Tags that are already manually linked to other resources.

​
Create interactive diagrams

1

Navigate to diagram parsing

Navigate to Data management > Contextualize > Diagram parsing.
2

Create interactive diagrams

Select Create interactive diagrams.
3

Select diagrams

Select the diagrams that you want to make interactive.You can filter the diagrams by Name, Data set, Label, or File type, such as PDF. For assets, you can also filter by Root asset.
The supported interactive diagram file mime_types are application/pdf, image/jpeg, image/png, and image/tiff. For more information, see API documentation for engineering diagrams.

Continue to next step

Select Next step to continue.
5

Optional. Link to other diagrams

Select the diagrams you want to link your diagrams to and select Next step.
6

Link to assets

Select the assets you want to link your diagrams to and select Next step. This limits the matching to assets from the same plant or unit as the selected diagrams.
7

Select contextualization model

Select a contextualization model:
Select model interface showing Standard and Advanced model options
  • The Standard model is selected by default as this model is recommended for most engineering diagrams.
  • The Advanced model lets you configure options such as the number of tokens matched for an entity, partial matches, and field matching.

Continue and run model

Select Next step.
Activate Save and skip settings if you always use the same model.
Select Run model.
