Method Details

deriveId

public static String deriveId(org.apache.jena.rdf.model.Resource r)

Create an Id from a given resource with the following precedence of preferences: - maven identifier - URI - generic hash

Parameters:

r -

Returns:

createDefaultJobHash

public static String createDefaultJobHash(Job job)

Create a hash for a given job Note, that this does not take any variable substitutions into account TODO The method should in addition to the hash return a label for the hash method used

Parameters:

job -

Returns:

executeJob

public static RdfDataPod executeJob(Op op)

Execute a basic workflow

Parameters:

op -

Returns:

Throws:

IOException

executeJob

public static DcatDataset executeJob(Job job,
 TaskContext taskContext,
 HttpResourceRepositoryFromFileSystem repo,
 ResourceStore cacheStore,
 ConjureFormatConfig formatConfig)

Execute a job and return a dcat model of the result

Parameters:

job -

taskContexts -

repo -

cacheStore -

Returns:

executeJob

public static RdfDataPod executeJob(Job job,
 HttpResourceRepositoryFromFileSystem repo,
 TaskContext taskContext,
 org.apache.jena.rdf.model.Resource inputRecord,
 org.apache.jena.riot.RDFFormat persistRdfFormat)

TODO The result of this computation are two datasets: The result dataset and its dcat record dataset. How to chache that? - Cache both - if so: What to use as the id of the metadata? Maybe $classifier$ + -meta? - Cache only the result dataset -

Parameters:

job -

repo -

taskContext -

inputRecord -

Returns:
