Sophie 2.0 consists of three editions(plug-in sets):

• org.sophie2.author
• org.sophie2.reader
• org.sophie2.server

Each edition is runnable through:

• Eclipse, using some fake classes that simulate plug-in behavior
• Apache Felix OSGI implementation.

Every edition has the following structure:

• / - main application catalog
  • /modules/ - containes plug-ins(in the form of jar-files or unpacked jar-files) that are/can be used in this edition
  • /conf/ - contains plug-ins configuration files and global configuration files
  • /log/ - contains application log(s)
  • /data/ - contains mutable resources(i.e book templates).
  • run-files

At this time each edition has its own module. It is responsible for loading the correct set of plug-ins.
