Extending object-schema-based application programming interfaces (APIS)

A system, comprising:

• a processor;
• and
• a memory comprising instructions which, when executed by the processor, performs an operation for extending an object schema-based application programming interface (API), the operation comprising:
• receiving, from a user, a schema defining an extension to the API and a reference to a parent node in a graph projection of the API, wherein the graph projection of the API comprises a number of navigable paths, each navigable path representing a function exposed by the API and wherein the extension defines a plurality of functions to be added to the API;
• verifying that the schema defines a valid extension to the API based at least in part on whether the navigable path comprises a continuous path exists in the graph projection of the API from a root node of the graph projection of the API to the node representing the extension by determining that a parent node of the extension is an existing node in the graph projection of the API;
• updating the graph projection of the API to include a node representing the extension and a navigable path to the node representing the extension;
• and
• processing a request from the user by traversing through the updated graph projection of the API, the request representing the navigable path to the node representing the extension.

A non-transitory computer-readable medium comprising instruction which, when executed on a processor, performs an operation for extending an object schema-based application programming interface (API), the operation comprising:

• receiving, from a user, a schema defining an extension to the API and a reference to a parent node in a graph projection of the API, wherein the graph projection of the API comprises a number of navigable paths, each navigable path representing a function exposed by the API and wherein the extension defines a plurality of functions to be added to the API;
• verifying that the schema defines a valid extension to the API based at least in part on whether the navigable path comprises a continuous path exists in the graph projection of the API from a root node of the graph projection of the API to the node representing the extension by determining that a parent node of the extension is an existing node in the graph projection of the API;
• updating the graph projection of the API to include a node representing the extension and a navigable path to the node representing the extension;
• and
• processing a request from the user by traversing through the updated graph projection of the API, the request representing the navigable path to the node representing the extension.
