TianGong TIDAS Tools User Guide

English | 中文

This toolkit is used for conversion and validation of TianGong TIDAS data formats.

---

1. Introduction

This toolkit contains two independent tools:

• TIDAS and eILCD Data Format Conversion Tool
• TIDAS Data Validation Tool

---

2. TIDAS and eILCD Data Format Conversion Tool Usage

(1) Installation Instructions

# Install this toolkit
pip install tidas-tools

(2) Tool Functionalities

This tool supports mutual conversion between the following two data formats:

• TIDAS data format → eILCD data format (default mode)
• eILCD data format → TIDAS data format

(3) Command-line Arguments

Argument	Short form	Description
--help	-h	Display help message
--input-dir	-i	Directory containing data files to be converted (note: this directory must directly contain the data files, not their parent directory)
--output-dir	-o	Output directory for converted data (the program will automatically generate the complete schema-compatible directory structure)
--to-eilcd		Convert data from TIDAS format to eILCD format (default mode)
--to-tidas		Convert data from eILCD format to TIDAS format
--verbose	-v	Enable verbose logging

(4) Usage Examples

# Convert TIDAS data to eILCD format
tidas-convert --input-dir <TIDAS_data_directory> --output-dir <eILCD_output_directory> --to-eilcd

# Convert eILCD data to TIDAS format
tidas-convert --input-dir <eILCD_data_directory> --output-dir <TIDAS_output_directory> --to-tidas

---

3. TIDAS Data Validation Tool Usage

(1) Tool Functionalities

This tool validates whether TIDAS data complies with the specified format standards.

(2) Command-line Arguments

Argument	Short form	Description
--help	-h	Display help message
--input-dir	-i	Directory containing TIDAS data to validate (note: this directory must directly contain the data files, not their parent directory)
--verbose	-v	Enable verbose logging

(3) Usage Example

# Validate TIDAS data format
tidas-validate --input-dir <TIDAS_data_directory>

4. TIDAS Export Tool Documentation

(1) Tool Functionalities

This tool exports data records in either TIDAS or eILCD format. It also optionally downloads supplementary files and bundles them into a final zip archive.

(2) Command-line Arguments and Environment Variables

Parameter	Short	Description
--help	-h	Display help information
--to-tidas	-	Export data in TIDAS format (default)
--to-eilcd	None	Export data in eILCD format
--input-dir	-i	Input directory containing files to export
--output-zip	-z	Output path for the zip file
--env-file	-e	Path to .env file containing DB and AWS credentials
--skip-external-docs		Skip downloading external supplementary files
--to-tidas		Export in TIDAS format (default option)
--to-eilcd		Export in eILCD format (mutually exclusive)
--db-user		Database username
--db-password		Database password
--db-host		Database host
--db-port		Database port (default: 5432)
--db-name		Database name
--aws-access-key-id		AWS access key ID
--aws-secret-access-key		AWS secret access key
--aws-region		AWS region
--verbose	-v	Enable verbose logging

Credentials can also be set via environment variables (defaults to the .env file in the current directory):

DB_USER=
DB_PASSWORD=
DB_HOST=
DB_PORT=5432
DB_NAME=postgres
AWS_REGION=
AWS_ENDPOINT=

(3) Usage Example

# Export records to TIDAS format and produce a ZIP archive.
tidas-export -i <TIDAS_input_directory> -z <TIDAS_ZIP_File> --to-tidas

# Export records to eILCD format without downloading supplementary files
tidas-export -z <eILCD_ZIP_File> --to-eilcd --skip-external-docs

---

5. Log File Information

Both data conversion and validation tools will automatically generate execution logs. The log file name is:

tidas-{function_name}.log

6. Development Environment Setup and Contribution Guide

If you wish to participate in development, you can set up your environment following these steps:

(1) Ubuntu System Environment Preparation

# Update repositories and install software management tools
sudo apt update
sudo apt install software-properties-common

# Add the official PPA repository for the latest Python version and install Python 3.12
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install -y python3.12

# Install necessary dependency packages
sudo apt install libxml2-dev libxslt-dev
sudo apt-get install build-essential python3-dev

# Upgrade software packages on the system
sudo apt upgrade

(2) Manage Python Environment with uv

# Install uv (if not already available)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Synchronize dependencies (including development tools)
uv sync --dev

# Activate the virtual environment created by uv (optional)
source .venv/bin/activate

# Run project commands without activating the environment
uv run python src/tidas_tools/convert.py --help

---

7. Code Standards and Testing

(1) Code Formatting Tool (black recommended)

# Automatically format code using black
uv run black .

(2) Testing Instructions

To test data conversion and validation functionalities, run the following commands:

# Test converting TIDAS data to eILCD format
uv run python src/tidas_tools/convert.py -i <TIDAS_data_directory> -o <eILCD_data_directory> --to-eilcd

# Test converting eILCD data to TIDAS format
uv run python src/tidas_tools/convert.py --input-dir <eILCD_data_directory> --output-dir <TIDAS_data_directory> --to-tidas

# Test TIDAS data validation functionality
# Execute automated tests
uv run pytest

# Validate TIDAS data
uv run python src/tidas_tools/validate.py -i <eILCD_data_directory>

---

8. Automatic Building and Publishing (CI/CD)

This project supports automatic building and publishing. When you push a git tag named with the v<version> format to the repository, it will trigger the workflow automatically. For example:

# List existing tags
git tag

# Create a new tag (e.g., version v0.0.1)
git tag v0.0.1

# Push the newly created tag to the remote repository to trigger automatic workflow
git push origin v0.0.1
