Installing / configuring mongodb

• Install mongodb server ("mongod") and mongodb client ("mongo", but there are also GUI clients) (these are usually in one package)
• if necessary: change spring.data.mongodb.* in application.properties
• use (databases are automatically created :-))

Getting started

• checkout https://github.com/freeplane/freeplane-events
• gradle build publishToMavenLocal
• checkout https://github.com/freeplane/freeplane-server
• gradle build cleanEclipse eclipse
• checkout https://github.com/freeplane/freeplane
• gradle checkout client
• gradle build cleanEclipse eclipse

• run a basic use case:
  • run org.freeplane.server.Application (as Java Application) from server repo
  • run freeplane-osgi launcher from freeplane repo
    • select the websockets check box
    • click button -> message interchange is triggered

Design

TODO:

• One client
  • Connect to server (web socket session) check
  • Create a new map on server and get its uuid check
  • Send updates to server and receive them back
  • Subscribes to updates for a given map id
  • Receives all updates from server for a given map id
    • From the beginning
    • From given map revision
    • Optimize: server skips overwritten updates of the same element (later)
• Many clients
  • Servers orders all updates from all clients, server changes map revisions for later updates if necessary
  • Server checks for conflicts in updates having the same map revision in the input events and notifies clients (later)
• OAuth2 authentication
  • Check authentication (full access for any clients with valid credentials, may be JWT tokens)
  • Manage write and read permissions for a map (API or browser app ?)

** Other issues * Extract events and serialization in a separate project to be used from both client and server check
