The features described in this section are currently in beta testing and are subject to change.
The GAP connector extracts the information model from GAP simulator model revisions. This feature parses the flowsheet hierarchy of GAP simulator model revisions, including functional blocks, such as process equipment, block properties, such as operating parameters, physical properties and configuration settings, connections between blocks, and graphical information for visualization processes. The connector stores the parsed information in Cognite Data Fusion (CDF) alongside the associated simulator model revision.

​
Prerequisites

Model parsing automatically activates when:
  • A valid modelparsing.config.yml file exists in the connector’s configuration directory.
  • Connector configuration automation.information-model-extraction-enabled is set to true.
  • A new simulator model revision is created or an existing model revision is reparsed.
  • The GAP model contains a single flowsheet.

​
Configure parsing

You configure the model parsing in a separate YAML file (modelparsing.config.yml) that defines which properties to extract from different equipment types. Use modelparsing.config.example.yml for guidance.

​
Configuration file structure

# Common properties extracted from all equipment types
common-properties:
  - name: OilRate
    value-type: DOUBLE
    unit:
      quantity: Liquid Rate
    description: Oil rate from the network solver.
    address-suffix: .SolverResults[0].OilRate
  - name: WaterRate
    value-type: DOUBLE
    unit:
      quantity: Liquid Rate
    description: Water rate from the network solver.
    address-suffix: .SolverResults[0].WaterRate

# Equipment-specific properties
equipment-properties:
  - equipment: well
    properties:
      - name: WellModel
        value-type: STRING
        description: Type of well model used.
        address-suffix: .WellModel
      - name: TypeWell
        value-type: STRING
        description: Type of well.
        address-suffix: .TypeWell
  - equipment: pipe
    properties:
      - name: PipeModel
        value-type: STRING
        description: Type of pipeline model used.
        address-suffix: .PipeModel
      - name: PipeCorr
        value-type: STRING
        description: Type of pipeline correlation used.
        address-suffix: .PIPECORR

​
Extract information

This is how the GAP connector extracts information from simulator model revisions:
1

Loads the model

When a simulator model revision is validated, the connector loads the GAP model.
2

Discovers equipment

The parser queries GAP to discover all equipment types and instances in the model.
3

Extracts properties

For each equipment instance, the parser:
  • Extracts common properties defined in the configuration.
  • Extracts equipment-specific properties based on the equipment type.
  • Retrieves unit information for numeric properties.
4

Generates edges

The parser analyzes equipment connections to generate edges representing material flows
5

Stores the information model

The complete information model is stored in CDF and associated with the simulator model revision.

​
Access parsed information

When a simulator model revision has been parsed, use the simulator model revision endpoints to fetch the associated flowsheet data.

​
Property extraction errors

During model parsing, the connector automatically skips any property where it fails to extract data to continue parsing. For example: Invalid address If the address-suffix contains a typo, for instance, .SolverResults[0].OliuRate instead of .SolverResults[0].OilRate, the property is skipped. Incorrect unit quantity If the specified unit.quantity doesn’t match the property type, for instance, using Temperature for a pressure value, the property extraction fails and is skipped. Wrong value type If the value-type doesn’t match the actual data type, for instance, specifying DOUBLE for a string property, the property is skipped and the connector logs details about the failed property extraction, continues processing remaining properties, and excludes the failed property from the final information model.

​
Limitations and considerations

  • Only GAP models with a single flowsheet are supported. The connector skips parsing for models with multiple flowsheets.
  • Model parsing requires a valid configuration file.
  • Model parsing adds processing time during model validation. The impact depends on model complexity.
  • Not all properties may be available for all equipment types. Missing properties are logged and skipped.
  • Unit information is retrieved when available, but may be missing for some properties.
  • Individual property extraction failures don’t stop the overall parsing process, but may result in incomplete information models.
