Caution

These are unofficial prototypes with fictional data. Features may be incomplete, and none of the applications is intended for production use.

A collection of experimental interfaces for finding, understanding, and documenting an organisation's data assets.

Prototypes

Prototype Focus Demo Details
Oblique Data Catalog Datenkatalog following the Oblique design system Open README
Business Object & Dataset Catalog Searchable DCAT-AP CH catalog Open README
SQLite Catalog Explorer In-browser SQLite catalog and lineage Open README
Architecture Layer Browser Conceptual, logical, and physical layers Open README
Data Lineage Viewer Interactive system and column lineage Open README
Mermaid Diagram Editor ER diagrams and flowcharts with free-text names Open README
Architecture Canvas Miro-style data-architecture modelling Open README
EA-IMMO Conceptual real-estate data model Open README

The catalog-oriented prototypes use DCAT-AP CH where relevant; other variants explore architecture, modelling, and lineage approaches.

Run locally

From the repository root, serve every browser prototype with:

python -m http.server 8000

Open http://localhost:8000; the root redirects to prototype-oblique/. Append a path from the table for another prototype.
