+Schemas that are JSON Schema and JSON-LD at once, so one document validates
+and carries its own semantics. [oo-ld.org](https://oo-ld.org)
+
+## What is here
+
+**Schema corpora.** The generated modules a benchmark reads: quantity kinds
+from QUDT, and classes from schema.org. Pinned by digest rather than by
+version, because two generations of the same corpus can differ in ways that
+change an answer.
+
+**Adapters.** LoRAs for schema-constrained extraction, each carded with what
+it was measured at and in which condition it is worth having. The short
+answer is: only where the prompt withholds the class catalogue. Where the
+catalogue is present, every one of them scores below the model it was trained
+from.
+
+**Results.** The graded cells behind the published figures.
+
+## The question they answer
+
+Where does structure have to be enforced for a model to produce data that
+validates: in the prompt, at decode time, at commit time, or nowhere. The
+code, the method and the findings are at
+[github.com/OO-LD/oold-llm-bench](https://github.com/OO-LD/oold-llm-bench).
