A simple but powerful interface to access the underlying big-data storage for setting and getting the meta-data associated with an entity object ( platform meta models)

Values can be stored as simple name value pair of strings or original datatypes like int, bool, etc..

/**
	 * Retrieve a stored property, return data is formatted if a format is specified while storing
	 * @return null if not found
	 */
	public Object property(String name);
	
	/**
	 * Retrieve a stored property, return data is formatted if a format is specified while storing
	 * @return def value if not found
	 */
	public Object getProperty(String name, String def);
	
	/**
	 * Store a named property
	 */
	public void property(String name, String value);


	/**
	 * Store a named property as JSON
	 */
	public void property(String name, Map<String, Object> value);

	/**
	 * Store a named property with one of the formats, during runtime in rules engine, platform will transform the data as
	 * JSON properties are returned as Map<String,Object>
	 * HEX & BASE64 properties a hex decoded and returned as byte[]
	 * @param format - [JSON | HEX | BASE64]
	 */
	public void property(String format, String name, String value);

	/**
	 * Store a boolean value in the lookup table
	 */
	public LookupContext put(String name, boolean value);

	/**
	 * Store a byte value in the lookup table
	 */
	public LookupContext put(String name, byte value);

	/**
	 * Store a short value in the lookup table
	 */
	public LookupContext put(String name, short value);

	/**
	 * Store a integer value in the lookup table
	 */
	public LookupContext put(String name, int value);

	/**
	 * Store a float value in the lookup table
	 */
	public LookupContext put(String name, float value);

	/**
	 * Store a double value in the lookup table
	 */
	public LookupContext put(String name, double value);

	/**
	 * Store a long value in the lookup table
	 */
	public LookupContext put(String name, long value);

	/**
	 * Store a String value in the lookup table
	 */
	public LookupContext put(String name, String value);

	/**
	 * Store a UUID value in the lookup table
	 */
	public LookupContext put(String name, UUID value);

	/**
	 * Store a byte[] value in the lookup table
	 */
	public LookupContext put(String name, byte[] value);

	/**
	 * Store a Map<String,Object> value in the lookup table
	 */
	public LookupContext put(String name, Map<String, Object> value);

	/**
	 * Retrieve a stored lookup value in its original format
	 */
	public Object get(String name);
	
	/**
	 * Retreive a stored lookup value in its original format, if not found returns the passed def value
	 */
	public Object get(String name, Object def);
