Maker TypeScript Discovery Boundary
In the public materials reviewed for this repo, Maker exposes a function-discovery path whose standalone install workflow is not clearly documented.
Package
Maker
The public ontology-as-code DSL; important because it kept expanding from object definitions into actions, imports, discovery, and compiler-facing workflows.
- Grew from basic ontology definitions into actions-as-code, imports, links, structs, value types, and query/function-related workflows.
- Picked up concrete compiler-facing features like branching support, direct datasources, PSGs, and query function discovery.
- Contains a TypeScript function-discovery hook that is not yet fully self-contained in the public package flow.
- Broad public DSL; TypeScript function discovery still crosses a private boundary.

Why it matters
Maker is the package to watch if you want the public face of Palantir’s ontology-as-code strategy.
What makes it significant is how quickly it expanded. The changelog shows a steady move from object definitions into actions-as-code, links-as-code, imports, interface actions, direct datasources, PSG handling, custom decimal/value formatting, and query function discovery.
That means Maker is no longer just a declarative DSL for ontology shape. It is increasingly the public authoring front-end for a broader compiler pipeline.
The important caveat is that its TypeScript function-discovery path is still not fully packaged as a self-contained public workflow, so one of the most interesting new flows still crosses a boundary outside the main public package surface.
Maker is both a substantial public DSL and the clearest example of a public/private seam in this package set.
