The basics

Java7 webapp

• Fedora is a standard Java7 web-application 
  • Jetty and Tomcat, or one-click
  • Deployed as a war
• Configuration via 
  • Configuration files
  • System-properties
  • Repository objects/resources

Maven3

• Build tool
• Manages library dependencies, build artifacts, code formatting, integration tests, release signing and deployment, code-coverage, etc
• Release artifacts are deployed to maven-central

Github

• https://github.com/fcrepo4
• https://github.com/fcrepo4-labs

Main F4 codebase

• fcrepo4
