Alligator | An Allen Transformator

About Alligator
  • Alligator reads the following items from an *.agt file: item name, the resulting "XYZ values" of a Correspondence Analysis, the start and end date and whether it is fixed or not. The *.agt format description can be found HERE and an example is available HERE.
    Out of the first 3 dimensions of a Correspondence data, all 3D distances are calculated. For items which are not fixed (floating), the "next fixed neighbour" (NFN) for start or end date will be searched. If the NFN is found, the virtual year will be taken. With this result and all new calculated "virtual" years, all Allen time intervals will be calculated. As a key feature, this calculation is downloadable as a Ressource Description Framework (RDF) file, following the alligator ontology.

How To

  • 1. Create a Alligator-File (*.agt). The format description can be found HERE, an example HERE.
  • 2. Select the output mode.
  • 3. Choose and upload the Alligator-File (*.agt).
