Today, more and more database companies and digital projects are using XML (Extensible Markup Language). Library professionals - especially technical service librarians, metadata librarians, system librarians, and library webmaster - who want to stay current, need this book. XML is becoming the standard for content description and metadata exchange. It can handle special characters and non-Roman scripts, which librarians often encounter in the bibliographic environment and offers the greatest promise of data longevity. This book will: introduce you to XML for resource description and bibliographic data management; show you how to create XML records for metadata encoding; help you understand and use DTD (Document Type Definition) and schema for texts, bibliographic catalogs and authority files; and show you how to deliver XML documents through the Web.
