Parameters:

url -

model -

Returns:

loadMemoryModel

public static com.hp.hpl.jena.ontology.OntModel loadMemoryModel(InputStream is,
                                                                String url,

Load an ontology into memory. Use this type of model when fast access is critical and memory is available.

Parameters:

is -

url, - used as a key

spec -

Returns:

loadMemoryModel

public static com.hp.hpl.jena.ontology.OntModel loadMemoryModel(String url)

Load an ontology into memory. Use this type of model when fast access is critical and memory is available. Uses OWL_MEM_TRANS_INF

Parameters:

url -

Returns:

loadMemoryModel

public static com.hp.hpl.jena.ontology.OntModel loadMemoryModel(String url,
                                                                String cacheName)

Load an ontology into memory. Use this type of model when fast access is critical and memory is available. Uses OWL_MEM_TRANS_INF If load from URL fails, attempt to load from disk cache under @cacheName.

Parameters:

url -

Returns:

loadMemoryModel

public static com.hp.hpl.jena.ontology.OntModel loadMemoryModel(String url,
                                                                com.hp.hpl.jena.ontology.OntModelSpec spec)

Load an ontology into memory. Use this type of model when fast access is critical and memory is available.

Parameters:

url -

Returns:

loadMemoryModel

public static com.hp.hpl.jena.ontology.OntModel loadMemoryModel(String url,
                                                                com.hp.hpl.jena.ontology.OntModelSpec spec,

Load an ontology into memory. Use this type of model when fast access is critical and memory is available. If load from URL fails, attempt to load from disk cache under @cacheName.

Parameters:

url -

spec - e.g. OWL_MEM_TRANS_INF

cacheName - unique name of this ontology, will be used to load from disk in case of failed url connection

Returns:

hasChanged

public static boolean hasChanged(String cacheName)

deleteOldCache

public static boolean deleteOldCache(String cacheName)

getDiskCachePath

public static File getDiskCachePath(String name)

Parameters:

name -

Returns:
