 Schema Salad
 ------------
 
-Salad is a schema language for describing JSON or YAML structured
-linked data documents.  Salad schema describes rules for
-preprocessing, structural validation, and hyperlink checking for
-documents described by a Salad schema. Salad supports rich data
-modeling with inheritance, template specialization, object
-identifiers, object references, documentation generation, code
-generation, and transformation to RDF_. Salad provides a bridge
-between document and record oriented data modeling and the Semantic
-Web.
+Schema Salad is a schema language for YAML (or JSON) that also lets
+you map your YAML data structures into RDF structured linked data
+documents via JSON-LD. In other words, a schema validates and
+transforms YAML or JSON documents into structured linked data
+documents - the missing link between a NoSQL JSON document and a
+linked data document that can be reasoned about, e.g. for human and
+machine processing.
