DataGraft is a data-as-a-service platform that allows data workers to easily transform tabular data into graph data through reusable transformations. It provides powerful data transformation capabilities and reliable data hosting and querying services. Data and transformations can be interactively designed, shared, and reused by other users. DataGraft has been successfully used in two pilots to transform property data into RDF, demonstrating its ability to reduce costs and increase the speed of publishing and reusing open data through a flexible and cloud-based system.
