 ### Structure
 
 Each package consists of:
-- **`ns.ttl`** - Ontology with vocabulary imports (`owl:imports`) and template blocks (`ldh:template`)
+- **`ns.ttl`** - Ontology with vocabulary imports (`owl:imports`) and property views (`ldh:view` / `ldh:inverseView`)
 - **`layout.xsl`** - XSLT stylesheet with custom rendering templates using system modes
 
 ### Installation

 - **Declarative only** - RDF + XSLT, no Java code
 - **Installation-time composition** - Pre-composed before loading, no runtime overhead
-- **Template blocks** (`ldh:template`) - SPARQL-based views attached to RDF types
+- **Property views** (`ldh:view` / `ldh:inverseView`) - SPARQL-based views attached to properties
 - **XSLT overrides** - Custom rendering using system modes (`bs2:*`, `xhtml:*`, etc.)
