Overview diagram

The PDO ontology, described using RDFS and OWL-DL, models the inherent structure and concepts of various documents in a project-specific setting, like meeting minutes, status reports etc. The scope of this ontology was limited to modelleing the discourse structure of various project documents like meeting minutes, status reports, final reports, deliverables, etc. The content of these documents is not modelled, in order to make the ontology very flexible and interoperable.

Care was taken to ensure that other domain ontologies can be easily linked. So, for instance, a meeting minute note might talk about anything from software projects to movie reviews but still be modelled by the ontology, while using the respective domain ontologies of software projects and movies.

A sample of using the ontology in Turtle format :

:x1 a pdo:Minutes;
  pdo:hasAttendee :Brian, :Siggi, :Pradeep;
  pdo:hasAbsentee :Tudor;
  pdo:contains [
    a pdo:ActionItem;
    pdo:hasComment "Brian to complete the task";
    pdo:hasOwner :Brian;
    pdo:hasEndDate "2010-03-10"^^xsd:Date];
  pdo:contains [
    a pdo:Poll;
    pdo:hasComment "Who is attending the conference?";
    pdo:hasOption [ pdo:hasComment "I am";
        pdo:hasSupportor :Brian];
    pdo:hasOption [ pdo:hasComment "I am not";
        pdo:hasSupportor :Pradeep, :Siggi]].


The ontology was initially developed for the extraction and management of the semi structured knowledge inherent in various formats of project-specific documents like meeting minutes and status reports, and to provide an inferencing layer on top of this knowledge for better information retrieval. The information in the documents would be extracted, instantiated against the ontology and stored in an RDF store for further inferencing. .
