Support both @view sugar AND explicit ui:view predicate #4

Summary

Support @view as built-in JSON-LD syntax in solid-shim, expanding to the jsonld:view predicate.

Live Implementation

🚀 See it working: https://jsonos.com/examples/

Background

@view should work like @type - zero context required:

{
  "@context": {"schema": "http://schema.org/"},
  "@type": "schema:Person",
  "@view": "https://example.com/panes/person.js",
  "schema:name": "Alice"
}

Just like @type expands to rdf:type, @view should expand to jsonld:view.

Implementation

When parsing JSON-LD, solid-shim should:

1. Recognize @view as a reserved keyword
2. Expand it to http://www.w3.org/ns/json-ld#view
3. Store the triple: <subject> jsonld:view <viewUrl>

// In parseJsonLdToStore or similar
if (data['@view']) {
  const VIEW = $rdf.Namespace('http://www.w3.org/ns/json-ld#')
  store.add(subject, VIEW('view'), $rdf.sym(data['@view']))
}

Semantic Equivalence

For interop with Solid's ui vocabulary:

jsonld:view owl:equivalentProperty ui:view .

This means queries for either predicate should match.

Why jsonld:view?

• JSON-LD native namespace
• W3C controlled
• Clear path to standardization
• Bridges to ui:view via equivalentProperty
