Abstract

One of the central problemsin creating information managementsolutionsfor precision dairy farmingis integration and interpretation of heterogeneous data coming from different equipment and data sources. Establishing a unifying data model is recognized as a cornerstone to suchsolutions.Here, the challenge lies both in agreeing on a common information context,and inselectingappropriate model representations, model query and update techniques,which guaranteemodel extensibility. While already existing ISOagriNETData Dictionaries capture broad variety of the livestock and dairy farming concepts,the existing model representation technics cannot support efficient model extension.In this paper,we presentour experience with using the representation and query standards and tools of the Semantic Web, endorsed by the World Wide Web Consortium (W3C),in particular the Resource Description Framework (RDF),the Web Ontology Language (OWL), and the SPARQL query standard,to encodeand manipulate the dairy farming domain knowledgeinaform of the Dairy Farming Ontology (DFO).Within the research project agriOpenLinkthe DFO has beencreated in two phases.The first phase focusedon using the Semantic Web tools to facilitate easy encoding and manipulation of the dairy farming domainknowledgeand the platform operational data models. The second phase focused on translating ISOagriNET Data Dictionaries into theirsemantic representations. Resulting DFO is maintained in a semantic repository, and it presents a knowledge graph and asintegration backbone for the agriOpenLinkdecision support platform.
