    This example shows how to create a block data set, store it in a JSON file, and then import the data set from the JSON file.

    Create a model that contains a Simscape block. This example uses a Capacitor block from the Foundation Library.

    modelName = "myModel";
close_system(modelName,0) 
libraryBlockName = "fl_lib/Electrical/Electrical Elements/Capacitor";
open_system(new_system(modelName));
blockName = add_block(libraryBlockName,modelName + "/" + "Example block");

    Create a block data set from the Capacitor block.

    myDataSet = partrepo.simscape.dataSetFromBlock(blockName)
    myDataSet = 

  BlockDataSet with properties:

            ID: "||" (format)
      Metadata: [1×1 Metadata] (11 entries, Incomplete)
    Parameters: [1×1 Parameters] (3 entries)

    In the Metadata property of the BlockDataSet object, add values for the Manufacturer and PartNumber properties.

    myDataset.Metadata.Manufacturer = "My Manufacturer";
myDataset.Metadata.PartNumber = "U312_45";

    Export the block data set to a JSON file. Use the part number as the file name.

    partrepo.exportDataSetsToJSON(myDataset,myDataset.Metadata.PartNumber)

    Import the block data set from the JSON file and display the data.

    results = partrepo.importDataSetsFromJSON('U312_45.json');
disp(results{1})
    myDataSet = 

  BlockDataSet with properties:

            ID: "My Manufacturer|U312_45|" (format)
      Metadata: [1×1 Metadata] (11 entries)
    Parameters: [1×1 Parameters] (3 entries)

    Input Arguments
