Methods

__construct()  : mixed

Creates a new metadata parser.

__destruct()  : mixed

forceUpdate()  : self

fromUrl()  : self

getState()  : string

Returns the state of the vocabulary in the repository:

import()  : array<string|int, RepoResource|ClientException>

Ingests the vocabulary and removes obsolete vocabulary entities (repository resources which were not a part of the ingestion but point to the schema repository resource with skos:inScheme or repoCfg:parent)

preprocess()  : MetadataCollection

Performs preprocessing - removes literal IDs, promotes URIs to IDs, etc.

setAddParentProperty()  : self

When $add is set to true, all repository resources representing imported skos entities are linked with the skos:Schema repository resource with a repository's parent property.

setAddTitle()  : MetadataCollection

Sets if the title property should be automatically added for ingested resources which are missing it.

setAllowedNamespaces()  : self

Set RDF property filter for skos resources.

setAllowedResourceNamespaces()  : self

Defines namespaces of RDF properties allowed to keep object values.

setAutoCommit()  : MetadataCollection

Controls the automatic commit behaviour.

setExactMatchMode()  : self

Sets up skos:exactMatch RDF triples handling where the object belongs or not belongs to a current vocabulary.

setImportCollections()  : self

Sets up if skos:Collection and skos:OrderedCollection nodes should be ingested into the repository.

setResource()  : MetadataCollection

Sets the repository resource being parent of all resources in the graph imported by the import() method.

setSkosRelationsMode()  : self

Sets up skos:semanticRelation RDF triples handling where the object belongs or not belongs to a current vocabulary.

setTitleProperties()  : self

Sets up which RDF properties a repository resource title for skos entities should be derived from.

assureLiterals()  : void

assureParents()  : void

assureTitles()  : void

dropNodes()  : void

dropProperties()  : void

filterResources()  : array<string|int, TermInterface>

Returns set of resources to be imported skipping all other.

fixReferences()  : void

To avoid creation of duplicated resources it must be assured every resource is referenced acrossed the whole graph with only one URI

mergeConcepts()  : void

processExactMatches()  : array<string|int, string>

processRelations()  : void

promoteBNodesToUris()  : void

Promotes BNodes to their first ID and fixes references to them.

Promotes subjects being fully qualified URLs to ids.

removeLiteralIds()  : void

Removes literal ids from the graph.

removeObsolete()  : void

sanitizeResource()  : DatasetNode

Cleans up resource metadata.
