Which element is considered the central foundation for developing custom applications within Foundry's toolchain?

• A. Slate
• B. Workshop
• C. Ontology SDK (OSDK)
• D. Developer Console

Answer: (C)

Foundry’s custom apps rely on a single, shared data model that defines what data means and how it relates. The Ontology SDK provides the tools to create, version, and enforce that model—defining the entities, attributes, relationships, and business rules that your apps depend on. Because every UI, workflow, and integration uses that ontology as a contract, the Ontology SDK sits at the foundation of the toolchain. The UI layer (Slate) pulls from this ontology to render forms and views, while the Workshop environment uses the same defined types to assemble workflows; the Developer Console interacts with ontology-backed data during development and debugging. Without establishing the ontology first, the other components wouldn’t have a consistent structure to rely on.
