  1. Cocoon and Digital Libraries in the Humanities Hugh A. Cayless UNC Chapel Hill

  2. outline • What is Apache Cocoon? • Why is it particularly useful for digital library applications in the Humanities? • Getting started with Cocoon • Some examples • A Cocoon webapp • Integrating software into Cocoon

  3. What is Apache Cocoon? • An XML-based (web) publishing framework written in Java • Some explanatory digressions: • XML • XSLT • SAX

  4. Digressions continued… • Wimmel, Walter (1960) Kallimachos in Rom, Wiesbaden. or • Galinsky, Karl (1969) "The Triumph Theme in the Augustan Elegy," Wiener Studien 82, 75-107.

  5. Digressions continued… • <p>Wimmel, Walter (1960) <i>Kallimachos in Rom</i>, Wiesbaden.</p> • <bibl> <title lang="deu">Kallimachos in Rom</title> <author> <persName> <foreName>Walter</foreName> <surName>Wimmel</surName> </persName> </author> <date>1960</date> <pubPlace>Wiesbaden</pubPlace></bibl>

  6. What is Apache Cocoon? • Some explanatory digressions: • XML • (e)X(tensible) M(arkup) L(anguage) • XSLT • (e)X(tensible) S(tylesheet) L(anguage) T(ransformations) • SAX • S(imple) A(PI) (for) X(ML)

  7. Cocoon continued… • More explanations: • Pipeline-based processing • Generators • Transformers • Serializers • Readers • The Sitemap • http://localhost:8080/cocoon/mystuff/mypage.html

  8. Cocoon continued… • Separation of Concerns

  9. SoC • How does this help? • Focus on establishing contracts, rather than training. • Scholars don’t have to radically change the way they do things. • Programmers don’t have to create systems from scratch.

  10. Humanities Digital Libraries • Characteristics • Often focused on documents • Multiple languages • Integration of images with texts desired • Integration of analytical tools • Good search and retrieval tools

  11. Humanities Digital Libraries • Obstacles • Time • Money • Unfamiliarity of content providers with technology • Unfamiliarity of technologists with content

  12. Cocoon’s Solutions • Time • Reduces the amount of time spent in negotiations between scholars and programmers • Reduces the actual amount of code that needs to be written.

  13. Cocoon’s Solutions • Money • It’s free • It can run in a servlet container that’s also free • It can run on a software platform that’s free

  14. Cocoon’s Solutions • Content providers • Only have to learn enough technology to provide the content with sufficient data and metadata.

  15. Cocoon’s Solutions • technologists • Can focus on solving specific problems posed by the material, e.g. writing code to analyze content.

  16. Getting Started • Downloads: • http://java.sun.com http://jakarta.apache.org/tomcat • http://xml.apache.org/cocoon • Installation: • Install Java • Install Tomcat • Put cocoon.war in tomcat/webapps/ • Start Tomcat

  17. Getting started • Documentation • Online documentation much improved • Very active user / development community • Books • Cocoon: Building XML Applications, Matthew Langham and Carsten Zeigler, New Riders, 2003. • Cocoon Developer’s Handbook, Lajos Moczar and Jeremy Aston, Developer’s Library, 2003.

  18. Some Examples • A cocoon web application: • EpiDocinator • Integrating software • Transcoder • CHET-C-java
