Project 2 - The First Data Holder

This was my first attempt at creating a data class to hold data from both MARC and EAD files.


/**

package crrasolrindexer;

import java.io.*;

/**

 * 
 *  *** NOTE: This is older than CRRA_Datum. It is recommended ***
 *  *** that you use CRRA_Datum instead for non-MARC records.  ***
 *  ***
 * 
 *    The IndexDatum class holds the kinds of data that are to be extracted
 *    from an indexed field, whether MARC or EAD (or anything else). All fields
 *    are private; only a protected method allows setting them, and a public
 *    method allows retrieving their contents. (The setField() method is
 *    protected so that one has to change the data through the appropriate
 *    class that indexes the data.
 *
 *    This class is designed to be easily extensible for use with other kinds
 *    of data.
