Metadata is a hight level data definition not supported (i think) in DBF format.
You can try it in Interbase 6 (open source).

/* Domain definitions */
CREATE DOMAIN ADDRESSLINE AS VARCHAR(30);
CREATE DOMAIN ADDRESSLINE AS VARCHAR(30);
CREATE DOMAIN COUNTRYNAME AS VARCHAR(15);
CREATE DOMAIN CUSTNO AS INTEGER
CHECK (VALUE > 1000);
CREATE DOMAIN FIRSTNAME AS VARCHAR(15);
CREATE DOMAIN LASTNAME AS VARCHAR(20);
CREATE DOMAIN PHONENUMBER AS VARCHAR(20);

/* Table: CUSTOMER, Owner: BUILDER */

CREATE TABLE CUSTOMER
(
CUST_NO CUSTNO NOT NULL,
CUSTOMER VARCHAR(25) NOT NULL,
CONTACT_FIRST FIRSTNAME,
CONTACT_LAST LASTNAME,
PHONE_NO PHONENUMBER,
ADDRESS_LINE1 ADDRESSLINE,
ADDRESS_LINE2 ADDRESSLINE,
CITY VARCHAR(25),
STATE_PROVINCE VARCHAR(15),
COUNTRY COUNTRYNAME,
POSTAL_CODE VARCHAR(12),
ON_HOLD CHAR(1) DEFAULT NULL,
PRIMARY KEY (CUST_NO)
);

As you can see some field ar referenced by a metadata (called here domanis)
so when you change the format of metadata all fields referenced by it
change automatically.

Hope this help.
