Method Details

getSupportedFormats

@STServiceOperation
public List<DataFormat> getSupportedFormats(String extensionID)

Returns the formats that are accepted by an extension implementing FormatCapabilityProvider.

Parameters:

extensionID -

Returns:

getParserFormatForFileName

@STServiceOperation
public String getParserFormatForFileName(String fileName)

Tries to match the extension of a file name against the list of RDF formats that can be parsed (see: Rio.getParserFormatForFileName(String)).

Parameters:

fileName -

Returns:

the name of the matched RDFFormat, or null if none is found

getWriterFormatForFileName

@STServiceOperation
public String getWriterFormatForFileName(String fileName)

Tries to match the extension of a file name against the list of RDF formats that can be written (see: Rio.getWriterFormatForFileName(String)).

Parameters:

fileName -

Returns:

the name of the matched RDFFormat, or null if none is found

Adds RDF data directly to the ontology being edited (i.e. it is not a read-only import of an external ontology that the working ontology depends on, but a mass add of RDF triples to the main graph of the working ontology). The data can originate from the body of the request (inputFile is non-null) or be fetched from some source, by means of a Loader (loaderSpec is non-null). A Loader can be associated with an RDFLifter (rdfLifter is non-null), when the data source is not a triple store (interpreted broadly as a source of RDF data). Whatever the source of the data is, it is possible to setup a transformationPipeline, to transform the data before feeding it to the repository. The presence of a transformation pipeline requires the creation of a temporary repository, where data are first loaded and processed.

Parameters:

inputFile -

baseURI -

format -

transitiveImportAllowance -

loaderSpec -

rdfLifterSpec -

transformationPipeline -

validateImplicitly -
