Load Table To Knowledge Graph (Knowledge Graph)

Summary

Loads data from a table or feature class into a knowledge graph.

Usage

• Use this tool to create entities and relationships in a knowledge graph from existing tabular data. Data in a table's fields can be converted into properties of entities and relationships.

• A data loading configuration file is required to load data into a knowledge graph. A data loading configuration file specifies how to read and handle the data in a table. It can also create provenance records to specify the source material from which the data was derived. Create a data load configuration file using the Load Table wizard.

• When the Input Data parameter value is a feature class, identify the geometry field in the attribute table. When the Input Data parameter value is a table, identify one or more fields containing coordinates that define the entity's geometry. Only the WGS84 coordinate system is supported for knowledge graphs. It is assumed that all features and coordinates will use this coordinate system.

Code sample

LoadTableToKnowledgeGraph example (stand-alone script)

The following code sample demonstrates creating a knowledge graph service using the LoadTableToKnowledgeGraph function with default parameters.

# Description: Load tabular data from a .csv file into a knowledge graph.

# Import system modules
import arcpy

# Set local variables
target_knowledge_graph = 'MyKnowledgeGraph'
in_dataset = 'data_load.csv'
data_loading_configuration = 'data_load_config_sample.ldcfg'

# Call the LoadTableToKnowledgeGraph tool to load data_load.csv into 
# "MyKnowledgeGraph" as defined by data_load_config_sample.ldcfg.
arcpy.kg.LoadTableToKnowledgeGraph(target_knowledge_graph, in_dataset,
                                   data_loading_configuration)
