1) The document describes a project called Semantics for Big Data Applications in Smart Dairy Farming which aims to incorporate semantics and linked data approaches to integrate and analyze sensor and production data from Dutch dairy farms. 2) An InfoBroker platform was developed to share cow-centric sensor and static data from multiple sources using semantic techniques like an ontology and linked data patterns while keeping the raw data decentralized. 3) Performance tests were conducted loading the dairy farm data, converted to RDF triples, into different triplestores and databases to evaluate their ability to handle complex queries against large datasets.
