Datomania

A public-data product around information that should be easier to access: provenance modeling, Representantes records, API/export routes, and methodology.

Public on gorkamolero 1,257 records API / export surfaces

Problem

Public-interest data often technically exists, but is hard to browse, verify, export, or use in software. A useful civic-data product needs more than a table: it needs provenance, methodology, API access, and a product surface that makes the data understandable.

What I Built

Datomania is documented as a public-data project around information that should exist in Spain. The rewritten README frames it around the Representantes dataset, 1,257 parliamentarians, provenance modeling, public API/export routes, architecture, methodology, status, and portfolio context.

Data product Public-interest dataset, browsing surface, methodology, and usability framing.
Provenance Source-aware modeling so records can be inspected rather than blindly trusted.
Developer surface API/export routes make the data useful beyond the UI.

System Architecture

Technical Decisions

  • Frame the project around public usefulness instead of only data collection.
  • Make provenance and methodology part of the product surface.
  • Expose API/export routes so the dataset can support downstream workflows.
  • Keep the README explicit about architecture and verification, not just a product description.

What This Proves

Datomania shows product judgment in a less glamorous but highly practical domain: turning messy public information into a browsable, inspectable, reusable data product with clear provenance and engineering discipline.
