Abstract: Embodiments presented herein provide techniques for rendering user-interface elements for an entity type based on a variation metamodel received in response to an API request. When a user invokes a function to access or create an entity, a user interface sends the API request to an API service. The API request identifies the entity type and is associated with context information about the user. The variation metamodel is selected by the API service based on the context information. The user interface receives and parses a response from the API service. The meta model includes metadata describing at least one aspect of a corresponding property of the entity type. Using the metadata as a guide, the user interface renders elements for the properties of the variation schema in a graphical user interface (GUI).

Abstract: The present disclosure relates to accessing data using application programming interface (API) calls. According to one embodiment, a method generally includes receiving, at the API, a request from a client device, where the requesting a data operation. Determining context data associated with the request. Receiving an entity schema based on the context data, where the entity schema includes a metamodel. Processing the request using the entity schema and metamodel, generating a response including the entity schema, and returning the response to the client device.

Abstract: The present disclosure relates to managing variability in an application programming interface (API). According to one embodiment, a method generally includes receiving, from a user, a definition of a variability schema and context information associated with the variability schema. The variability schema generally represents a variation of one or more properties defined in an application programming interface (API). A computing system links the variation and context information to the one or more properties defined in the API. The computing system receives a query to perform one or more actions using the one or more properties, matches context information associated with the query to the context information associated with the variability schema, and processes the query using the variation of the one or more properties.
