A linked data developer is responsible for designing, implementing, and managing web-based data structures. They use technologies like RDF, SPARQL, and HTTP to connect related data from different resources, enabling efficient data integration, sharing, and reuse. They create systems that make data easily accessible and understandable, often for use in machine learning or AI. They work closely with other developers, data scientists, and stakeholders to ensure data is properly linked and available for use, often involving data modelling, mapping, and conversion. Their work contributes to the broader field of semantic web development, which aims to make data more meaningful and interconnected.
