Autogenerated GraphQL types

When you have defined an industrial knowledge graph with the data modeling REST API, use the GraphQL interface to query and mutate data in the instances mapped by the views in your graph.

note

The capabilities available via the GraphQL interface to data modeling represent a subset of the available capabilities from the DMS query and ingestion endpoints.

CDF will automatically generate GraphQL types for the collection of views making up a DMS data model.

An example generated type:

type Movie {
  "name of the movie" # inlined property description
  name: String! # an exclamation mark denotes a required property
  actors: [Actor] # A connection property. Is resolved by the GraphQL interface
  director: Person # A direct relation property. Can be resolved by the GraphQL interface.
  watchedIt: Boolean
}

📄️ GraphQL queries

You can query the instances with GraphQL. The query capabilities of the GraphQL API interface represent a subset of the capabilities available from the DMS query endpoints.

📄️ GraphQL mutations

You can create and update instances using GraphQL. The mutation capabilities available from the GraphQL API represent a subset of the capabilities of the ingestion REST API endpoints. The GraphQL interface for data modeling doesn't anticipate receiving significant data ingestion traffic. For that, please use the DMS REST API, or the CDF Transformations service.
