 == How We Store and Exchange of Textual Information ==
 
-Exchanging information between two well-known applications is relatively simple because when we know exactly what all the data values on both sides of the exchange represent it is easy to map them together.  But when we move toward the vision of ISO 15926 where anything-can-talk-to-anything worldwide, we can no longer count on knowing anything at all about the information on the other side of the transaction.
+One of the first uses of computers was to manage large bodies of written information.  But as we have all personally experienced, hardware and software changes every few years.  Every time an organization changes its technology, its entire document collection has to be moved to the new system.  Because of the immense size of some of these collections, rekeying is impossible.
 
-In order to transmit information reliably to a random receiver, we must have a common method of classifying things.  This is the study of Taxonomy and Ontology.
+From this need we now have well-developed technology for moving text in a way that preserves any embedded context, or meaning.  One example is XML, which is used by many systems as a transport language.  It is a marriage of the lowest common denominator, ASCII text files which virtually every computer system worldwide can read, with the sophistication of being able to embed complex definitions and relationships.
 
-ISO 15926 classifies plant objects using an open, extensible Ontology.
+ISO 15926 uses XML to transport information.
