        public static WorkCatalog loadInstance​(PegasusProperties props)
                                        throws WorkFactoryException
        Connects the interface with the work catalog implementation. The choice of backend is configured through properties. This class is useful for non-singleton instances that may require changing properties.
        Parameters:
        props - is an instance of properties to use.
        Throws:
        java.lang.ClassNotFoundException - if the schema for the database cannot be loaded. You might want to check your CLASSPATH, too.
        java.lang.NoSuchMethodException - if the schema's constructor interface does not comply with the database driver API.
        java.lang.InstantiationException - if the schema class is an abstract class instead of a concrete implementation.
        java.lang.IllegalAccessException - if the constructor for the schema class it not publicly accessible to this package.
        InvocationTargetException - if the constructor of the schema throws an exception while being dynamically loaded.
        WorkFactoryException
