Helio is a framework that allows generating and publishing RDF data from different heterogeneous sources as Linked Data.

---

What Helio can do for you

For users Helio generates synchronously or asynchronously Knowledge Graphs from a set of heterogeneous sources:

• Generating the RDF of the KG into a file
• Link resources using linking rules
• Use different mapping languages to generate RDF and links among its resources
• Use an external triple store as Helio database
• Publish the RDF as a Linked Data Service (providing access to resources, a SPARQL endpoint, and the whole dataset)
• Customise the HTML views of the Linked Data Service
• Create views dynamically combining data of different RDF resources
• Provide an integrated view of different distributed Helios or SPARQL endpoints

For developers Helio can be used as a maven dependency for:

• Generating RDF and links among resources
• Developing plugins for new functionalities
