Description

Session Goal

The session aimed to develop a comprehensive tool for extracting DBF files and converting them into CSV format, along with implementing a command-line interface for managing data extraction tasks.

Key Activities

• Developed a Python script for extracting DBF files from specified input directories, applying optional column exclusions, and generating corresponding CSV files in organized output directories.
• Implemented the extract_dbf_to_csv function in extractor.py, enabling recursive directory traversal and file classification.
• Completed the scaffold for extractor.py, integrating logic for DBF to CSV conversion and export functionality.
• Created a command-line interface (CLI) for the eph-extractor, including commands for fetching, extracting, and verifying data from the EPH dataset.

Achievements

• Successfully developed and integrated the DBF to CSV extraction script and CLI tool.
• Completed the scaffold for extractor.py with logic for recursive directory traversal and export functionality.

Pending Tasks

• Add unit tests to ensure the functionality of the extractor.
• Complete the implementation of validator.py and metadata.py.
• Adjust the CLI to accommodate new functionalities.
