public class DcatVocabulary
extends Object

DcatVocabulary defines the IRIs of the classes and properties from the W3C Data Catalog Vocabulary (DCAT) version 3, and the vocabularies that it reuses, that are understood by Egeria. It also supplies the standard prefixes for these vocabularies and the plain names commonly used for the terms in JSON-LD contexts.

Method Details

getStandardPrefixes

public static Map<String,String> getStandardPrefixes()

Return the standard prefixes for the vocabularies used in DCAT descriptions. They are used when writing a document and, when reading, to resolve a prefix that the document did not define.

Returns:

map of prefix to namespace IRI

getPlainTerms

public static Map<String,String> getPlainTerms()

Return the IRIs for the plain names that are commonly given to DCAT terms by JSON-LD contexts (for example "title" for dct:title). They are used when reading a document that relies on a context that is not embedded in the document.

Returns:

map of plain name to IRI

getStandardNamespace

public static String getStandardNamespace(String prefix)

Return the IRI of the standard namespace for a prefix.

Parameters:

prefix - prefix

Returns:

namespace IRI or null

compact

public static String compact(String iri)

Shorten an IRI using the standard prefixes.

Parameters:

iri - full IRI

Returns:

compact IRI (prefix:name) or the supplied IRI if it is not from one of the standard namespaces
