The Agricultural Ontology Service: A Proposal to Create a Knowledge Organisation Framework in the Area of Food and Agriculture Johannes Keizer, Food and Agriculture Organization of the UN, Library and Documentation Systems Division Kick Off Workshop Rome 14th/15th November 2001 Slide 20 Discussion Points  What kind of need do you see for a meta-ontology paralleling what the UMLS has done? For what would you use such a system?  Is it conceivable to run this project as a series of pilot projects with subject domains (e.g., forestry, fisheries, sustainable development, crop wild relatives) – in the end building the complete AOS?  What issues do you see regarding the building of ontological associations?  Who should participate in the project as full partners and who as peripheral partners? What are their respective responsibilities?  Who are the primary and secondary user types for the AOS?  What toolkit will be needed to create and maintain the AOS? What are the components of this toolkit?  What encoding standards should be used (e.g., RDF, DAML+OIL)?
