LMLparser(diagramName)[source]¶

This method is designed to parse the xml file containing the MBSE model, to create its corresponding graph and to populate:

the set of entities: dictionary of assets in the form of ‘LML_ID’: (‘asset name’, ‘asset ID’)
the set of links: list containing the LML-IDs of all links between assets
the set of embedded entities: dictionary of the components that have been specified in the description text of the LML asset or link (e.g., [comp1,comp2,comp3]) in the form of ‘LML_ID’: [comp1,comp2,comp3]

Parameters:: diagramName – string, original name of the diagram; it is used to remove the correposing node in the graph

connetGraph()[source]¶: This method is designed to actually link the asset entities identified in the OPLparser method

parseLinkEntity(linkNode)[source]¶

This method extracts all required information of the link from the provided xml node. It populates the self.linkEntities and the self.embEntities variables.

Parameters:

linkNode – xml node, xml node containing containing all the information of a single link generated
Innoslate (in LML using)

Returns:

None

parseAssetEntity(entityNode)[source]¶

This method extracts all required information of the asset from the provided xml node. It populates the self.entities and the self.embEntities variables.

Parameters:

linkNode – xml node, xml node containing containing all the information of a single link generated
Innoslate (in LML using)

Returns:

None

returnGraph()[source]¶

This method returns the networkx graph

Parameters:: None
Returns:: networkx object, graph containing entities specified in the LML MBSE model
Return type:: self.LMLgraph

returnEntities()[source]¶

This method returns the the dictionaries of entities and embedded entities specified in the MBSE model

Parameters:: None
Returns:: dict, dict of entities self.embEntities : dict, dict of embedded entities
Return type:: self.entities

returnListIDs()[source]¶

This method returns the list of asset IDs

Parameters:: None
Returns:: list, list of asset IDs specified in the LML MBSE model
Return type:: self.listIDs

cleanedGraph()[source]¶

This method is designed to clean the complete MBSE graph by removing the links which are represented as nodes

Parameters:: None
Returns:: networkx object, cleaned graph containing only asset entities specified in the LML MBSE model
Return type:: g

createNeo4jGraph()[source]¶

src.dackar.utils.mbse.LMLparser.parseEntityDescription(text)[source]¶

This method is designed to extract the elements specified in square brackets that are specified in the description node of the MBSE model of a link or entity

Parameters:: text – str, text contained in the description node of the MBSE model
Returns:: tuple, tuple containing the list of elements specified in square brackets and separated by commas (e.g., [‘FV304,’305’]) and the link to an external MBSE model (e.g., (‘centrifugalPumpFull’, ‘body’))
Return type:: out
