Kepler Architecture Notes (Monday, May 2005)

• The problems:
• Versioning
• Conflicts in Dependency Chains (underlying classes and their dependencies)
• instead of class names, use lsids
• no way to uniformly manage objects (workflows, data, libraries/dependencies, etc.)
• no way to "seamlessly" transport objects
• both publish and download
• no way to manage local versus remote objects
• lsids plus object cache ("intelligent" object cache)
• dynamically load classes into current Java Classloader
• no central repository(ies)
• periodic indexing of HDD in background
• no good way to create functional groups
• e.g., the core group, plus packages for geospatial, rexpression, etc.
• a lighter weight kepler
