Where to go when data alone is not enough

Everything in this tutorial was done with data: documents, queries and authorizations, applied over HTTP. That is the ceiling of the low-code approach — and it opens. Each layer of LinkedDataHub can be extended without forking it:

• Layout — write an XSLT stylesheet that imports the system one and overrides only the templates you need. Start with the Change layout guide and the stylesheets reference.
• Docker — mount files into the stock image, or build your own image on top of it. The Build apps guide covers both with working build files.
• Java — add JAX-RS endpoints via a WAR overlay of the LinkedDataHub webapp.
• More examples — the LinkedDataHub-Apps repository holds the complete Northwind Traders source alongside further demo apps and installable packages.

If you get stuck or build something worth showing, open a thread on GitHub Discussions.

You have built and published a Knowledge Graph dataspace. From here: the user guide for everyday tasks, the reference for the full feature set, and the Extending section when you outgrow low-code.
