 CSVW makes extensive use of other standards (such as [JSON-LD](https://www.w3.org/TR/json-ld/), [XML Schema Datatypes](https://www.w3.org/TR/xmlschema11-2/), Compact URIs) and defines how to use those. It also has specifications on how to transform CSVW to [JSON](https://www.w3.org/TR/2015/REC-csv2json-20151217/) and [RDF](https://www.w3.org/TR/2015/REC-csv2rdf-20151217/). CSVW is not defined as a JSON Schema.

This file links to the data file(s) using [resource.path](https://csvw.datapackage-6gp.pages.dev/standard/data-resource/#path-or-data) and can reference external dialects, schemas, and (domain-specific) specifications.
