Syntax

public abstract class BaseDescribeAlgorithm : IDescribeAlgorithm

Methods

Describe(IRdfHandler, ITripleIndex, IEnumerable<INode>, Uri, INamespaceMapper)

Generates a graph which is the description of the resources represented by the provided nodes.

Declaration

public void Describe(IRdfHandler handler, ITripleIndex dataset, IEnumerable<INode> nodes, Uri baseUri = null, INamespaceMapper namespaceMap = null)

Parameters

Type	Name	Description
IRdfHandler	handler	The handler to receive the triples that provide the description.
ITripleIndex	dataset	The dataset to extract descriptions from.
IEnumerable<INode>	nodes	The nodes to be described.
Uri	baseUri	An optional base URI to pass through to the RDF handler.
INamespaceMapper	namespaceMap	An optional namespace map to pass through to the RDF handler.

Describe(ITripleIndex, IEnumerable<INode>)

Generates a Graph which is the description of the resources represented by the provided nodes.

Declaration

public IGraph Describe(ITripleIndex dataset, IEnumerable<INode> nodes)

Parameters

Type	Name	Description
ITripleIndex	dataset	The dataset to extract descriptions from.
IEnumerable<INode>	nodes	The nodes to be described.

Returns

Type	Description
IGraph

DescribeInternal(IRdfHandler, ITripleIndex, IEnumerable<INode>)

Generates the Description for each of the Nodes to be described.

Declaration

protected abstract void DescribeInternal(IRdfHandler handler, ITripleIndex dataset, IEnumerable<INode> nodes)

Parameters

Type	Name	Description
IRdfHandler	handler	RDF Handler.
ITripleIndex	dataset	Dataset to extract descriptions from.
IEnumerable<INode>	nodes	Nodes to be described.

RewriteDescribeBNodes(Triple, Dictionary<string, INode>, INodeFactory)

Helper method which rewrites Blank Node IDs for Describe Queries.

Declaration

protected Triple RewriteDescribeBNodes(Triple t, Dictionary<string, INode> mapping, INodeFactory factory)

Parameters

Type	Name	Description
Triple	t	Triple.
Dictionary<string, INode>	mapping	Mapping of IDs to new Blank Nodes.
INodeFactory	factory	Factory to create Nodes in.

Returns

Type	Description
Triple
