Constants

META_IDS  = 'ids'
Provide only a `resourceUrl titleProperty title` triple for a requested resource/resources matching the search.
META_NEIGHBORS  = 'neighbors'
Include metadata of all resources a given one points to and all resources which point to it. If parentProperty is specified, only resources pointing to a given one with a specified RDF predicate are included.
META_NONE  = 'none'
Provides no metadata.
META_PARENTS  = 'parents'
Like `relatives` but follows the parentProperty predicate only from subject to object.
META_PARENTS_ONLY  = 'parentsOnly'
Like `relativesOnly` but follows the parentProperty predicate only from subject to object.
META_PARENTS_REVERSE  = 'parentsReverse'
Like `relativesReverse` but follows the parentProperty predicate only from subject to object.
META_RELATIVES  = 'relatives'
Include metadata of all resources which can be reached from a given one by following (in both directions) an RDF predicate specified by the parentProperty as well as all metadata of all resources a given resource points to.
META_RELATIVES_ONLY  = 'relativesOnly'
Include metadata of all resources which can be reached from a given one by following (in both directions) an RDF predicate specified by the parentProperty
META_RELATIVES_REVERSE  = 'relativesReverse'
Include metadata of all resources which can be reached from a given one by following (in both directions) an RDF predicate specified by the parentProperty as well as all metadata of all resources a given resource points to and all resources pointing to a given one.
META_RESOURCE  = 'resource'
Provide only given resource's metadata

Methods

__construct()  : mixed
Creates an object representing a repository resource.
getClasses()  : array<string|int, string>
Returns all RDF types (classes) of a given repository resource.
getDissServices()  : array<string|int, Service>
Returns list of dissemination services available for a resource.
getGraph()  : DatasetNodeInterface
Returns resource metadata.
getIds()  : array<string|int, string>
Returns an array with all repository resource identifiers.
getMetadata()  : DatasetNodeInterface
Returns resource metadata.
getRepo()  : RepoInterface
Returns repository connection object associated with the given resource object.
getUri()  : TermInterface
Returns the repository resource URL.
isA()  : bool
Naivly checks if the resource is of a given class.
loadMetadata()  : void
Loads current metadata from the repository.
setGraph()  : void
Replaces resource metadata with a given RDF graph. A reference to the provided metadata is stored meaning future modifications of the $metadata object automatically affect the resource metadata.
setMetadata()  : void
Replaces resource metadata with a given RDF resource graph. A deep copy of the provided metadata is stored meaning future modifications of the $metadata object don't affect the resource metadata.

Constants

META_IDS

Provide only a `resourceUrl titleProperty title` triple for a requested resource/resources matching the search.

public mixed META_IDS = 'ids'

META_NEIGHBORS

Include metadata of all resources a given one points to and all resources which point to it. If parentProperty is specified, only resources pointing to a given one with a specified RDF predicate are included.

public mixed META_NEIGHBORS = 'neighbors'

META_PARENTS

Like `relatives` but follows the parentProperty predicate only from subject to object.

public mixed META_PARENTS = 'parents'

META_PARENTS_ONLY

Like `relativesOnly` but follows the parentProperty predicate only from subject to object.

public mixed META_PARENTS_ONLY = 'parentsOnly'

META_PARENTS_REVERSE

Like `relativesReverse` but follows the parentProperty predicate only from subject to object.

public mixed META_PARENTS_REVERSE = 'parentsReverse'

META_RELATIVES

Include metadata of all resources which can be reached from a given one by following (in both directions) an RDF predicate specified by the parentProperty as well as all metadata of all resources a given resource points to.

public mixed META_RELATIVES = 'relatives'

META_RELATIVES_ONLY

Include metadata of all resources which can be reached from a given one by following (in both directions) an RDF predicate specified by the parentProperty

public mixed META_RELATIVES_ONLY = 'relativesOnly'

META_RELATIVES_REVERSE

Include metadata of all resources which can be reached from a given one by following (in both directions) an RDF predicate specified by the parentProperty as well as all metadata of all resources a given resource points to and all resources pointing to a given one.

public mixed META_RELATIVES_REVERSE = 'relativesReverse'

META_RESOURCE

Provide only given resource's metadata

public mixed META_RESOURCE = 'resource'

Methods

__construct()

Creates an object representing a repository resource.

public __construct(string $url, RepoInterface $repo) : mixed
Parameters
$url : string

URL of the resource

$repo : RepoInterface

repository connection object

getClasses()

Returns all RDF types (classes) of a given repository resource.

public getClasses() : array<string|int, string>
Return values
array<string|int, string>

getDissServices()

Returns list of dissemination services available for a resource.

public getDissServices() : array<string|int, Service>
Return values
array<string|int, Service>

getGraph()

Returns resource metadata.

public getGraph() : DatasetNodeInterface

Fetches them from the repository with the loadMetadata() if they were not fetched already.

A reference to the metadata is returned meaning adjusting the returned object automatically affects the resource metadata.

getIds()

Returns an array with all repository resource identifiers.

public getIds() : array<string|int, string>
Return values
array<string|int, string>

getMetadata()

Returns resource metadata.

public getMetadata() : DatasetNodeInterface

Fetches them from the repository with the loadMetadata() if they were not fetched already.

A deep copy of metadata is returned meaning adjusting the returned object does not automatically affect the resource metadata. Use the setMetadata() method to write back the changes you made.

getUri()

Returns the repository resource URL.

public getUri() : TermInterface
Return values
TermInterface

isA()

Naivly checks if the resource is of a given class.

public isA(string $class) : bool

Naivly means that a given rdfs:type triple must exist in the resource metadata.

Parameters
$class : string
Return values
bool

loadMetadata()

Loads current metadata from the repository.

public loadMetadata([bool $force = false ][, string $mode = self::META_RESOURCE ][, string $parentProperty = null ][, array<string|int, string> $resourceProperties = [] ][, array<string|int, string> $relativesProperties = [] ]) : void
Parameters
$force : bool = false

enforce fetch from the repository (when you want to make sure metadata are in line with ones in the repository or e.g. reset them back to their current state in the repository)

$mode : string = self::META_RESOURCE

scope of the metadata returned by the repository - one of RepoResourceInterface::META_* constants.

$parentProperty : string = null

RDF property name used to find related resources in some modes

$resourceProperties : array<string|int, string> = []

list of RDF properties to be includes for a resource (if the list is empty, all exsiting RDF properties are included)

$relativesProperties : array<string|int, string> = []

list of RDF properties to be includes for resources being relatives (if the list is empty, all exsiting RDF properties are included)

setGraph()

Replaces resource metadata with a given RDF graph. A reference to the provided metadata is stored meaning future modifications of the $metadata object automatically affect the resource metadata.

public setGraph(DatasetInterface $metadata) : void

New metadata are not automatically written back to the repository. Use the updateMetadata() method to write them back.

Parameters
$metadata : DatasetInterface

setMetadata()

Replaces resource metadata with a given RDF resource graph. A deep copy of the provided metadata is stored meaning future modifications of the $metadata object don't affect the resource metadata.

public setMetadata(DatasetNodeInterface $metadata) : void

New metadata are not automatically written back to the repository. Use the updateMetadata() method to write them back.

$metadata : DatasetNodeInterface
