Loki Semantic Wiki

BiFröST Framework

Other Projects


Welcome to the Loki!

This is a wiki about the projects developed by GEIST Team at AGH-UST & Jagiellonian University in Kraków, Poland:

Loki - semantic wiki:

  • semantic annotations
  • SPARQL and ASK queries
  • RDF/XML export
  • SPARQL Endpoint
  • Reasoning Unit Tests
  • powered by SWI-Prolog

DokuWiki as a base:

  • web interface
  • easy collaboration (e.g. user accounts and ACLs)
  • unlimited versioning
  • simplicity (based on PHP and plain text files)

BiFröST Framework för Semantical Tracking:

Semantic Business Platform - business processes (BPMN) and rules (SBVR):

  • business process modeling
  • simplebpmn syntax
  • BPMN → simplebpmn converter
  • rules visualisation
  • XML & XMI export
  • If you want to know more: BPwiki, SBVRwiki

Note: projects are presented in one Demo wiki but they are independent - you can simply pick the plugins that you are interested in and install them.
The systems are under development and may be updated frequently.
