• Internal namespaces for ontologies (xmpp://schwarz@xmpp.km.opendfki.de/ont/ludopinions#UsesDice)
  • this way people can create own ontologies, and ontology management/evolution can be done similar to facts synchronization
  • perhaps create a kind of "RDF importer" that changes namespaces
• UI improvements
  • show number of (existing) feature instances for each item (in ItemPane)
  • show number of feature instances for each feature class (in FeaturePane) and arithmetic mean/standard deviation for applicability
• Malte's TODOs
  • implement basic Jabber stuff (​http://www.incava.org/projects/java/java-diff/ as Java Diff implementation?)
• Facts/graph synchronization idea
  • every peer implements
    • String getDiffForNamespace(String namespace, String haveHash, String wantHash)
    • String getMostCurrentHash()
    • String isValid(String hash)
    • String getPubkey()
    • ? subscribe(?)
  • logic: once a day, every machine dumps its 'own' facts to an NTriples file along with a timestamp and the data's hash
  • when peers call getDiffForNamespace(), a diff from haveHash.dat to wantHash.dat is calculated and sent
  • Distributed Storage
    • simple distributed storage (without signatures) with trust can be implemented usind getMostCurrentHash and isValid
    • distributed storage with signatures can be implemented with getPubkey (using a true keyserver might be desirable though)
    • optimized push synchronization could use some subscription mechanism. Integrate with ​XMPP pubsub?
  • Ontology evolution/rules
    • rules that upgrade existing facts could be added to the diff file
