@shexjs/extension-map

ShExMap: a semantic-action extension that binds values as a node validates (%Map:{ :name %} on a triple constraint captures what the triple's object was) and materializes a graph of another schema from those bindings. The extension registers as http://shex.io/extensions/Map/#.

npm install @shexjs/extension-map

• shexmap-materialize -t target.shex [-j vars.json] [-r root] reads the bindings shex-validate --extension @shexjs/extension-map printed and builds the target graph (doc/threaded-materializer.md says how: a threaded search over the target schema, alternatives offered where the bindings could fit more than one way).
• shexmap-debug steps that materialization from a terminal.
• In the web app, shex-simple.html?plugin=…/doc/ShExMapPlugin.js (or shexmap-simple.html) adds the bindings, output-schema and materialization panes; the plugin is built from src/plugin/ShExMapPlugin.ts by npm run build, which also compiles the library into lib/.

The library (require("@shexjs/extension-map")) is a factory taking the ShEx modules it works with and answering the extension -- register(validator, {ShExTerm}), the ThreadedMaterializer and its debugger; see the repository for the ShExMap specification and examples/ for worked pairs.

@shexjs/extension-map is one of the shex.js packages; installing shex pulls in the whole suite, and its README maps them.
