+The semantic API behind OLI-it, https://www.oli-it.com  
+All Entitites with endpoints for html, json, and RDF
+
+> This repository is a fork from an old OLI-it project in Azure DevOps.  
+
+
+## Goal
+
+The goal is to have a RDF API again for OLI-it deployed to https://nulllogicone.net/ 
+
+
+## Visualize
+
+https://issemantic.net/rdf-visualizer
+
+## Approach
+
+ create a new dotnet Core Web + Api project for html, json and rdf output.
+
+## ToDo
+
+[x] Move legacy projects to archive folder, delete it soon.  
+[x] Deploy to real Azure App Service site, configure DNS.  
+[x] Create GitHub Actions for automated deployment  
+[ ] Add more OLI-it entities (SAPCT-NKBZ).  
+[ ] Improve RDF output with more ontologies.  
+[ ] Add SPARQL endpoint.  
+
+
