A live graph of the tutorials, missions, and concepts that make up developers.sap.com, built by AI and powered by SAP HANA Cloud.
How it's built
Every night, a CAP cron job hands each tutorial's markdown to SAP AI Core. The model extracts concepts (e.g. CAP, SAPUI5, HANA Cloud) and the edges between them — what a tutorial teaches, what it requires. Those facts are stored as canonical CDS entities in SAP HANA Cloud, then projected into two of the database's built-in graph engines: the Knowledge Graph Engine, where SPARQL answers "what should I learn next?" in single-digit milliseconds, and a Property Graph workspace, where GraphScript algorithms (SHORTEST_PATH for Joule's learning paths, PageRank for authority ranking, Louvain for community detection, weakly-connected-components for isolation checks) run over the same tutorials and concepts. One database, two graph shapes, no ETL between them.
Tutorials are only the anchor corpus. Alongside them, nightly fetchers pull in the wider SAP developer ecosystem and run the same concept-extraction pipeline over every item, so a search for CAP or HANA Cloud reaches across all of it: Learning Journeys from learning.sap.com, blog posts from the SAP Community, Discovery Center missions and BTP services from discovery-center.cloud.sap, videos from the SAP Developers YouTube channel (including SAP Developer News and Tech Bytes), API references from the SAP Business Accelerator Hub, canonical code samples from the SAP-samples GitHub org, and upcoming community events (CodeJams, Devtoberfest, TechEd, user groups). A dedicated Help Docs corpus merges four documentation surfaces into one:
- help.sap.com — official SAP product documentation.
- cap.cloud.sap — the CAP framework docs (Node.js and Java).
- ui5.sap.com — SAPUI5 SDK reference, API, and samples.
- architecture.learning.sap.com
— the SAP Architecture Center: North Star docs, AI-golden-path
guides, and reference blueprints from
SAP/architecture-center.
Every resource — tutorial, journey, blog post, mission, video, API, sample, help doc, event — lands on the same concept vocabulary, so the graph you explore is one graph across all of it, not a dozen siloed catalogs sitting next to each other.
What's in the graph
Tutorials
—Every tutorial in the sap-tutorials/* GitHub org. Edges: teaches Concept, requires Concept.
Concepts
—AI-extracted topics — CAP, SAPUI5, HANA Cloud, … Edges: requires Concept, relatedTo Concept.
Missions & groups
—Curated learning paths. Edges: containsTutorial.
The tech behind it
SAP HANA Cloud Knowledge Graph Engine
RDF triple store; SPARQL via SYS.SPARQL_EXECUTE.
SAP HANA Cloud Property Graph
GraphScript algorithms — SHORTEST_PATH, PageRank, Louvain, WCC — over the same vertices & edges.
SAP HANA Cloud Vector Engine
Embedding similarity. Powers concept consolidation.
SAP HANA Cloud Multi-Model
Graph, vector, and relational data — one database, no ETL.
SAP AI Core / Generative AI Hub
LLM extracts concepts from tutorial markdown nightly; a weekly consolidator merges near-duplicates.
SAP Cloud Application Programming Model (CAP)
Service layer, scheduler, and the cron jobs that build the graph.
SAP BTP Cloud Foundry
The runtime.
All four HANA tiles run on the same SAP HANA Cloud instance — that's the multi-model story.
