Submodules

filip.semantics.ontology_parser.post_processer module

The PostProcessing gets called after the vocabulary was parsed from sources

The postprocessing has the goal to add predefined values, compute combinedRelations, reload user settings, and precompute information as: duplicate labels or sort relations

class filip.semantics.ontology_parser.post_processer.PostProcessor[source]

Bases: object

Class offering postprocessing as cls-methods for a vocabulary

classmethod post_process_vocabulary(vocabulary: Vocabulary, old_vocabulary: Vocabulary | None = None)[source]

Main methode to be called for post processing

Parameters:

  • vocabulary (Vocabulary) – Freshly parsed Vocabulary

  • old_vocabulary (Vocabulary) – Existing Vocabulary of which the settings should be overtaken

Returns:

None

classmethod transfer_settings(new_vocabulary: Vocabulary, old_vocabulary: Vocabulary)[source]

Transfer all the user made settings (labels, ..) from an old vocabulary to a new vocabulary

Parameters:

  • new_vocabulary (Vocabulary) – Vocabulary to which the settings should be transferred

  • old_vocabulary (Vocabulary) – Vocabulary of which the settings should be transferred

Returns:

None

filip.semantics.ontology_parser.rdfparser module

Module contains the RDFParser that can create a Vocabulary object out of a given ontology

class filip.semantics.ontology_parser.rdfparser.RdfParser[source]

Bases: object

Class that parses a given source into a vocabulary.

current_class_iri

Iri of class which is currently parsed, used for Log entries

current_source

parse_source_into_vocabulary(source: Source, vocabulary: Vocabulary) → bool[source]

Parse a Source into the given vocabulary :param source: :type source: Source :param vocabulary: :type vocabulary: Vocabulary

Returns:

bool, True if success, False if Error occurred, as an invalid File
