New release of DataGraft!

We are delighted to announce the second beta release of the DataGraft platform!

What is DataGraft?

DataGraft serves as the core of the proDataMarket producer portal. DataGraft is an online platform that provides data transformation, publishing and hosting capabilities that aim to simplify the data publishing lifecycle for data workers (i.e., Open Data publishers, Linked Data developers, data scientists).

The DataGraft platform mainly consists of three components – the DataGraft portal, Grafterizer and a cloud-enabled semantic graph database-as-a-service (as shown on the picture below), which is based on a dedicated instance of the Ontotext GraphDB Cloud platform mentioned in a previous blog post.
