-# OpenAPI Initiative Registry
+# OpenAPI Initiative Publications
 
-This site contains the OpenAPI Initiative Registry and content for the HTML versions of specifications managed by the OpenAPI Initiative such as the OpenAPI Specification and the Arazzo Specification.
+This site contains the authoritative HTML renderings of the OpenAPI Initiative's [specifications](#specifications) and [extension registries](#registries), as well as official (but non-[normative](https://en.wikipedia.org/wiki/Normativity#Standards_documents)) [schemas](#non-normative-json-schemas) for those specifications that provide them.
 
-## Registry
+Please see the [Learn OpenAPI](https://learn.openapis.org) site for additional documentation and [examples](https://learn.openapis.org/examples/), and the [OpenAPI Tooling](https://tools.openapis.org/) site for community-provided lists of tools implementing the specifications.

+
+## Non-Normative JSON Schemas
+
+_Note that while schemas can catch many errors, they are not guaranteed to catch all specification violations.  In the event of a disagreement between the schemas and the corresponding specificaton text, the specification text is presumed to be correct._
+
+### Arazzo Schemas
+
+_TBD_
+
+### OpenAPI Specification Schemas
+
+Note that the OAS 3.1 `schema/YYYY-MM-DD` schema does _not_ validate the Schema Object, as it makes no assumptions about the JSON Schema dialect in use.  The OAS 3.1 `schema-base/YYYY-MM-DD` schema _does_ validate the Schema Object, and requires that if `jsonSchemaDialect` or `$schema` are present, that they use the appropriate `dialect/YYYY-MM-DD`.  The name `schema-base` comes from the JSON Schema dialect including the OAS extensions being referred to as the "base dialect" in the specification.
+
+See [issue #4147](https://github.com/OAI/OpenAPI-Specification/issues/4147) for discussion of other possible JSON Schema dialect options, [issue #4152](https://github.com/OAI/OpenAPI-Specification/issues/4152) for programmatic access to the latest schemas, and [issue #4141](https://github.com/OAI/OpenAPI-Specification/issues/4141) for discussions on possibly providing linting schemas that could catch likely problems that do not directly violate the specification.
