Description

Session Goal

The session aimed to implement a command-line interface (CLI) for the eph-extractor tool, focusing on data fetching, verification, and extraction processes.

Key Activities

• Developed CLI commands: ‘fetch’, ‘verify’, and ‘extract’, each handling specific tasks related to data management.
• Implemented a downloader script to facilitate the downloading and extraction of quarterly data files from the INDEC server.
• Corrected the download_quarter function to improve error handling, file naming, and configuration loading.
• Updated Python code for better file handling and extraction, enhancing user feedback with logging messages.
• Proposed improvements for organizing the raw/eph/ directory, including creating quarterly subdirectories and an automated cleanup script.
• Detailed a CLI command function for downloading and processing quarterly data, managing metadata, and performing optional cleanup.

Achievements

• Successfully implemented and tested CLI commands for the eph-extractor.
• Enhanced the downloader script and file handling processes with improved logging and error handling.

Pending Tasks

• Define the schema for ‘processed.json’.
• Add tests for the newly implemented CLI commands.
