D.Hub at a glance — the map of five surfaces
A one-line tour of each sidebar surface (Collection · Pipeline · Ontology · Dashboard · Agent) and what kind of result it produces.
5 min
When you open D.Hub portal, the left sidebar shows five entries: Collection · Pipeline · Ontology · Dashboard · Agent. These are D.Hub's five result-producing surfaces. This lesson nails down what each surface answers, in one line.
The five surfaces in one table
| Surface | The question it answers | What it produces |
|---|---|---|
| Collection | "What data do I have, and where is it?" | Bundles of datasets · codes · pipelines · dashboards |
| Pipeline | "How do I automatically derive a processed result from raw data?" | Code-node chains, scheduled runs |
| Ontology | "How does my data fold into a conceptual model as a graph?" | Entities + relations + graph instances |
| Dashboard | "How do I show results to a person on one screen?" | Combinations of widgets (KPI · charts · tables · maps) |
| Agent | "How do I automatically route natural-language input through tools and decisions?" | One cycle of tools + actors + LLM |
The five depend on each other. A collection holds the data, a pipeline processes it, the ontology binds it into a graph, the dashboard shows it, and an agent pulls it back via natural language.
Two entry points beyond the sidebar
Two other entry points come up often.
- Global search — From anywhere, hit ⌘K (Mac) or Ctrl+K to search resource names · tags · body content at once. The fastest path when you can't recall an exact name.
- Home — Recently accessed resources, favorites, and the AI Assistant entry point land here. The daily-first stop.
What you should be able to do after this lesson
- Name the five surfaces (Collection · Pipeline · Ontology · Dashboard · Agent) and what each answers
- Recall the global search shortcut and where the home screen sits
