• Remove all unused and legacy code. This will be 2.0.
  • XML RDF export
  • Rabbitmq monitoring using manager API (Maxwell Burnette started on this)
  • Geostreams API (Todd Nicholson will do this ) - branch https://opensource.ncsa.illinois.edu/bitbucket/projects/CATS/repos/clowder/compare/commits?sourceBranch=refs%2Fheads%2Frefactor%2F2.0-remove-geostreams
  • Deprecated endpoints (Maxwell working on this)
  • Every plugin should become a Guice Trait + Implementation (2.1?)
    • For services that are not implemented, provide an no-op implementation
    • Enabled/disabled, is it in the config? Is it a common trait and the ability to provide implementation class in config file?
  • ??? (Add by end of this week Nov. 1st)
• Elasticsearch upgrade?
• New MongoDB implementation. This will be 3.0+.
  • Replace Salat and Cashbah with Java Mongo Driver and keep the rest as is
    • Mongo drivers
      • http://mongodb.github.io/mongo-java-driver/ (this might be our safest bet)
      • http://mongodb.github.io/mongo-java-driver-reactivestreams/
      • https://mongodb.github.io/mongo-scala-driver/
  • Split services in two layers.
    • Top layer has the common code that calls the other services. For example when removing a dataset also remove files.
    • Bottom layer is traits to do CRUD operations on resources and requires multiple implementations.
• Modify code to be compatible with newer versions of Playframework. 4.0+
  • Should jump straight to 2.7 or 2.6. We need to figure out which one. 
  • Migrate authentication / authorization:
    
    • https://github.com/mohiva/play-silhouette
• How do tests factor in? can we start writing them before the refactoring? For example unit tests of services vs play scala tests of controllers actions.
• Enforce style as part of this process. Using IDE? We should look at what rules and style software to use.

  • Pick our preferred rules
