Abstract

Automated interface creation from DTDs One of the biggest challenges of any publishing system is to remove as much complexity from the users’ tasks as possible. When dealing with a relatively new technology like XML/XSL this aspect of the system becomes even more important. By hiding the syntax of XML from the editors and authors, domain experts can take on the role of creating and modifying the content without worrying about the syntax of a particular markup language. One goal of Franklin, therefore, is to never present the tagging syntax to the user. Instead, Franklin creates a set of input forms that the user can easily fill out. However, some users insisted on placing simple HTML markup into text fields. Franklin does allow a small subset of HTML tags to be processed. However, this defeats many of the reusability and cross-platform publishing opportunities and is not a recommended strategy. Users are assigned roles in the system and each role, in turn, is assigned specific document types. A user assigned to a role can only create or modify a document assigned to that role. When the user selects a document type to create or edit, Franklin reads in the DTD and automatically constructs an interface based on that document structure.
