Because XML, by definition, stores content in a standardized, open format, it offers greater long-term benefits for information longevity and value. The Computer Age has already experienced many examples of “data obsolescence” — think of 5.25 inch floppy tasks, DOS files, or early word processing formats. Because XML is not proprietary, any software that recognizes the XML standard will be able to view and process XML files well into the future. Furthermore, because XML separates the content from the presentation, that content can be preserved as presentation technologies change over time. Since HTML is primarily intended to display content in a Web browser, its format mixes the content with the presentation in a way that makes it difficult, if not impossible, to separate out only the content for preservation.
