See all- From REST to reasoning: ingest, index, and query with dlt and CogneeLink visible for attendees
In this hands-on workshop, we'll walk through building a knowledge graph from REST API documentation using dlt and Cognee. Rather than treating APIs as flat data sources, we'll model their underlying concepts—resources, relationships, endpoints, and behaviors—as a structured graph of interconnected nodes.
Using dlt, we'll extract and transform documentation from multiple REST APIs into structured representations. These are then embedded into a shared semantic space using Cognee, where a central ontology node anchors all inputs—linking method definitions, OpenAPI specs, and DLT-specific constructs across APIs.
We'll explore:
- How to extract and normalize API docs into semantic node sets
- How to build and extend a central ontology that connects multiple API sources
- How to visualize and query the resulting knowledge graph to answer conceptual questions.
By the end of the session, you'll know how to construct and query a multi-source, semantically-indexed knowledge graph, enabling richer understanding of complex API ecosystems.
