LDT vocabulary

This document summarizes the AtomGraph Processor vocabularies in a human-readable form. For RDF versions, see the resources folder.

The ldt: namespace URI is https://www.w3.org/ns/ldt#.

Applications

Classes

ldt:Application

AtomGraph Processor application

ldt:Ontology

A class of sitemap ontologies

Properties

ldt:ontology

Application ontology

OWL ontology with resource classes (templates)

ldt:baseUri

Templates

Classes

ldt:Template

A class of RDF resources that share the same URI template and SPARQL query template

Properties

These properties can be used on Linked Data Templates:

ldt:query

SPIN query to retrieve resource description (DESCRIBE or CONSTRUCT)

ldt:update

SPIN update to remove resource description

ldt:path

URI template for resource matching

See also JAX-RS URI template syntax.

ldt:skolemTemplate

Container-relative URI template for blank node skolemization

See also JAX-RS URI template syntax.

ldt:param

Query string parameters as ldt:Arguments

ldt:lang

rdf:List of BCP47 language tags

ldt:cacheControl

Value of the HTTP Cache-Control response header

ldt:loadClass

Indicates the Java class that will handle requests matched by this template. Needs to start with java: URI scheme.

Additionally, these properties from the SPIN vocabulary are supported.

spin:constructor

SPIN constructor query (CONSTRUCT)

spin:constraint

SPIN constraint query

HATEOAS

These properties are added by AtomGraph to resource descriptions to enable HATEOAS state transitions over HTTP:

dh:forClass

Links to constructor resource for the specified class

dh:pageOf

Links page resource to its container resource

dh:limit

LIMIT modifier value for the first SELECT sub-query

dh:offset

OFFSET modifier value for the first SELECT sub-query

dh:orderBy

Variable name of the default ORDER BY for the first SELECT sub-query

dh:desc

If true, sets DESC on ORDER BY for the first SELECT sub-query

dh:slug

A string that will be used to build URI from template such as /{slug}

Classes

Built-in Linked Data Templates

dh:Container

Resource container

Subclass of core:Document and sioc:Container

URI template matches request URIs with a trailing slash: {path: .*}/

dh:Item

Document resource

Subclass of core:Document and sioc:Item

URI template matches all request URIs: {path: .*}
