What's a good way to manage custom schema for DS 5.1?

Question

What's a good way to manage custom schema?
Custom Schema for Object Class and Attributes
The reason I ask this is because there might be a need in the future where I need to export those custome schema into different branded directory server. I just want to make this as painless as possible.
Right now, I thought of 2 options
1) Create my own LDIF file with my custom attributes and object classes, so if one day I need to export to another directory server, I can just copy that custom created LDIF file over. (Will this work?)
2) Create a JAVA application using JNDI. What this Java App. will do is read through a XML file and create those object classes and attributes on-the-fly. (of course, the XML structure will be predefined by me, so that my Java App. will be able to parse through it correctly. Will this work?)
Anymore suggestion? I would want to hear more advices and suggestions.
Also, I assume that will work even with replication. All I need to update is the master server, and the slaves will replicate automatically.
Thank you very much! :)

Demo: I'm using the nul character to represent the end of the word, so that the data structure can represent that "hell" and "hello" are both in the vocabulary:
import java.util.*;
class Node {
    private SortedMap<Character, Node> children = new TreeMap<Character, Node>();
    //0 <= index <= word.length()
    private void add(String word, int index) {
        if (index == word.length()) {
            children.put(Character.valueOf('\u0000'), null);
        } else {
            char ch = word.charAt(index);
            Node child = children.get(ch);
            if (child == null) {
                children.put(ch, child = new Node());
            child.add(word, index+1);
    public void add(String word) {
        if (word == null || word.length()==0)
            throw new IllegalArgumentException();
        add(word, 0);
    public String toString() {
        return children.toString();
public class Example {
    public static void main(String[] args) throws Exception {
        Node root = new Node();
        root.add("hello");
        root.add("how");
        root.add("who");
        root.add("hell");
        System.out.println(root.toString());
}
