xforms for metadata creation
DESCRIPTION
As distributing metadata creation to authors, catalogers and other system users who may or may not have an understanding of XML becomes more and more important it has become imperative to develop reliable methods for creating and editing XML documents. This presentation will focus on the two MODS editors developed by UVM and Brown Universities and introduce the XForms technology as a means for digital libraries to create and manage complex metadata.TRANSCRIPT
XForms for Metadata Creation
Winona SaleskyUniversity of Vermont

The Problem
“XForms is an XML application that represents the next generation of forms for the web.”
- XForms 1.1 Specification
Enter XForms
XForms - the highlights
- Platform and device independent- Separates data and logic from
presentation- XML in, XML out- XML Schema validation- Reduces or eliminates the need for
scripting- Does not require expensive round-
tripping when the data is modified
