How to read SolidWorks part custom properties from SolidWorks eDrawings?

Is it possible to retrieve the Custom Properties from an .hsf or .easm file? The properties were added to parts in SolidWorks, and appear in their eDrawings. Screenshots and files attached. Any sample code using the Java wrappers would be greatly appreciated. Many thanks!

@Gareth,

Take a look at Exchange Integration — HOOPS Visualize HPS Documentation “Handling Metadata”.
