makeClassGroupsFromRootClasses

public static org.apache.jena.ontology.OntModel[] makeClassGroupsFromRootClasses(WebappDaoFactory wadf,
                                                                                 org.apache.jena.rdf.model.Model tboxModel)

Creates a set of vitro:ClassGroup resources for each root class in an ontology. Also creates annotations to place each root class and all of its children in the appropriate groups. In the case of multiple inheritance, classgroup assignment will be arbitrary.

Parameters:

wadf - DAO Factory

tboxModel - containing ontology classes

Returns:

resultArray of OntModels, where resultArray[0] is the model containing the triples about the classgroups, and resultArray[1] is the model containing annotation triples assigning ontology classes to classgroups.

extractABox

public org.apache.jena.rdf.model.Model extractABox(org.apache.jena.query.Dataset unionDataset,
                                                   org.apache.jena.query.Dataset baseOrInfDataset,

removeWithBlankNodesAsVariables

public static void removeWithBlankNodesAsVariables(org.apache.jena.rdf.model.Model toRemove,
                                                   org.apache.jena.rdf.model.Model removeFrom)

Remove statements from a model by separating statements containing blank nodes from those that have no blank nodes. The blank node statements are removed by treating blank nodes as variables and constructing the matching subgraphs for deletion. The other statements are removed normally.

Parameters:

toRemove - containing statements to be removed

removeFrom - from which statements should be removed

removeUsingSparqlConstruct

public static void removeUsingSparqlConstruct(org.apache.jena.rdf.model.Model toRemove,
                                              org.apache.jena.rdf.model.Model removeFrom)

Remove statements from a model by first constructing the statements to be removed with a SPARQL query that treats each blank node ID as a variable. This allows matching blank node structures to be removed even though the internal blank node IDs are different.

Parameters:

toRemove - containing statements to be removed

removeFrom - from which statements should be removed
