How to Add New Models and Methods

The list of model and method entities is compiled from Yaml assets located in the ./assets directory using the build_entities.js script. The assets processed by this script usually involve custom Yaml types such as !combine to generate several entity configurations at once.

A new model or method may be added either by extending parameters of an existing entity or by adding a new asset file such as the following:

!combine
name:
  template: 'Model{{ "-" + parameters.example }}' # set the model name using a template

# Loop over parameters to create combinations
forEach:
  - !parameter
    key: parameters.example # path of where to set the property
    values: ["A", "B", "C"] # values to iterate over
    isOptional: true

# static configuration (same for all created entities
config:
  tags:
    - example_model
    - tutorial
  schema: !esse 'schema-id-placeholder' # add a schema using the !esse type to validate each configuration 

The above asset file will create four model configurations, "Model-A", "Model-B", "Model-C", and "Model". The latter entity is created due to the isOptional flag of the example parameter. There are a few more options available to customize the entity asset, for instance, the !combine type has an exclusions property where conflicting pairs of entity properties can be defined, so that combinations of those will be avoided.

For more examples, please see the asset files in ./assets or code.js for the definition of Yaml types such as !combine or !parameter.

MoDe

The MoDe package is used in conjunction with the ADe package to define top-level parameters present in Subworkflow units in the WoDe package ecosystem. The entities provided by MoDe are:
