Building a Semantic Layer for Brazil’s Official Economic Data

Developer Felipe Gambetta de Souza has introduced 'Open Economics,' an open-source project designed to normalize Brazil's fragmented official economic data. While the initial goal was to unify disparate APIs from institutions like the Central Bank and IBGE, the author discovered that the primary challenge was preserving the semantic meaning of economic concepts rather than just technical integration. The project implements a two-tier system: semantic resolution to identify the correct concept, and data availability to retrieve the specific official series. To ensure transparency, the system embeds detailed provenance metadata into every result. Furthermore, the author optimized the platform for AI agents by creating a remote MCP (Model Context Protocol) server. By providing bounded textual representations alongside structured data, the system allows AI models to perform accurate, source-verified economic queries without external tools. The project is currently open-source and seeks community feedback on complex data scenarios.
