Author:

Jeremy Debattista The Quality Metadata Class provides a number of methods that enables the representation of Quality Metadata as described by the Dataset Quality Ontology (DAQ).

Constructor Summary

Constructor and Description
QualityMetadata(com.hp.hpl.jena.query.Dataset dataset, com.hp.hpl.jena.rdf.model.Resource computedOn) Used when the assessed dataset is stored in memory (Jena Dataset),
QualityMetadata(com.hp.hpl.jena.rdf.model.Resource datasetURI, boolean sparqlEndpoint) Since each assessed dataset should have only one quality metadata graph, we need to check if it already exists in the cache.

Constructor Detail

QualityMetadata

public QualityMetadata(com.hp.hpl.jena.rdf.model.Resource datasetURI,
               boolean sparqlEndpoint)

Since each assessed dataset should have only one quality metadata graph, we need to check if it already exists in the cache.

Parameters:

datasetURI - - The assessed dataset

sparqlEndpoint - - True if the datasetURI is a sparql endpoint.

QualityMetadata

public QualityMetadata(com.hp.hpl.jena.query.Dataset dataset,
               com.hp.hpl.jena.rdf.model.Resource computedOn)

Used when the assessed dataset is stored in memory (Jena Dataset),

Parameters:

dataset - - Assessed Jena Dataset

computedOn - - The resource indicating the metrics computed on

Method Detail

addMetricData

public void addMetricData(QualityMetric metric)

Creates observational data for the assessed metric

Parameters:

metric - - Metric Class

createQualityMetadata

public com.hp.hpl.jena.query.Dataset createQualityMetadata()
                                                    throws MetadataException

Creates quality metadata

Returns:

Dataset with quality metadata which needs to be attached to the assessed dataset.

Throws:

MetadataException - if there is no observation data calculated.
