Using Schematron for Analyzing Conformance to Best Practices for EAD, TEI, and MODS (and some other thoughts on workflow tools)
- 1. Using Schematron for Analyzing Conformance to Best Practices for EAD, TEI, and MODS (and some other thoughts on workflow tools) Jenn Riley Metadata Librarian Indiana University Digital Library Program
- 2. Consistency is a challenge Document-centric XML (TEI, EAD) is very difficult to create consistently Some common tools to help: ◦ ◦ ◦ ◦ ◦ ◦ Schema/DTD validation Tag libraries XML templates Example documents Keyboard macros Detailed encoding guidelines These are not enough! 7/11/09 ALA 2009 - ALCTS NRMIG 2
- 3. Another possible tool layer Machine validation of a file against local encoding guidelines Can only go so far, but that far is extremely helpful Indiana University implemented using: ◦ Schematron (http://www.schematron.com) ◦ <oXygen />plugin architecture 7/11/09 ALA 2009 - ALCTS NRMIG 3

- 12. More info on Schematron ISO/IEC 19757 - Document Schema Definition Languages (DSDL) - Part 3: Rule-based validation – Schematron. Be careful! http://www.schematron.com has the primary specs; http://schematron.com is for a particular company’s tool using them. (Weird.) This is the page you want: 7/11/09 ALA 2009 - ALCTS NRMIG 12
- 13. Using a Schematron file Schematron home page provides two distributions: ◦ One for XSLT 1.0 processors and one for 2.0 processors ◦ Each includes a set of three stylesheets to be used in turn on the Schematron file ◦ Result of this processing is a stylesheet to be run on your XML instance document IU implementation wraps this all up into an <oXygen />plugin written in Java You could also pipe them together with a shell script, a Windows .bat file, etc…… 7/11/09 ALA 2009 - ALCTS NRMIG 13

- 17. Let’s step back How can better tools revolutionize metadata creation workflows? ◦ Promoting consistency This is hard and not something that humans are generally good at ◦ True interoperability between systems Without futzing! We spend too much valuable human time doing repetitive and low-value tasks as part of descriptive workflows 7/11/09 ALA 2009 - ALCTS NRMIG 17
- 18. Were do we go from here? Make better use of available technologies ◦ Automating ◦ Streamlining ◦ Validating We can and must do our jobs better and more efficiently, with the help of better tools ◦ Providing comparable services with less ◦ Creating a convincing argument for more? 7/11/09 ALA 2009 - ALCTS NRMIG 18
- 19. There is no excuse for not having usable metadata creation tools. Smart systems are possible and necessary ◦ Configurable ◦ Modular ◦ Connected Make it easy to do it well ◦ Consistent ◦ Complete ◦ Efficient Make it hard to do it poorly We must pay attention to user interface design for cataloging tools 7/11/09 ALA 2009 - ALCTS NRMIG 19
