iemap-mi 0.2.3

A Python module to interact with the IEMAP REST API

Iemap-MI Python Module

Iemap-MI is a Python module that provides easy access to the IEMAP REST API.
It includes functionality for user authentication, fetching paginated project data, and more.
The module is designed to be used asynchronously and leverages httpx for making HTTP requests
and pydantic for data validation.

Documentation

For full documentation, visit iemap-mi documentation.
For a full working example, see examples.py (create metadata for a new project, add project to IEMAP platform, add files to project, query data) inside iemap_mi folder. Full documentation for REST API endpoint is available at
IEMAP-MI REST API Swagger generated documentation.

Features

• JWT Authentication: Authenticate users and manage sessions with JSON Web Tokens.
• Project Data: Fetch paginated project data from the API. Add new projects metadata, add file, and more.
• Asynchronous Requests: Utilize httpx for efficient, asynchronous HTTP requests.
• Data Validation: Ensure data integrity with pydantic models.
• AI functionalities based on a Graph neural networks (GNNs): aiding in the discovery and design of new battery materials
• Semantic search: Not yet implemented. Stay tuned!

AI Model

The geoCGNN model is inspired by the research paper published in Nature Communications:
"Crystal Graph Convolutional Neural Networks for Analyzing Materials Properties"
(https://www.nature.com/articles/s43246-021-00194-3).

This model has been further trained and optimized by ENEA on the High-Performance Computing (HPC)
infrastructure CRESCO (https://ict.enea.it/cresco/) to predict formation energy and redox potential,
aiding in the discovery and design of new battery materials.

Installation

To install the module, use poetry:

poetry add iemap-mi

Alternatively, you can install it using pip:

pip install iemap-mi

Note on IEMAP Projects metadata

Projects on IEMAP platform are stored as:

• General project metadata with a predefined schema
• Files related to project (allowed extensions are: csv, pdf, doc, docx, cls, xlsx, dat, in, cif)

Project metadata are stored onto MongoDB (and are searchable) while files are stored onto Ceph FS.
The metadata schema is the following:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {

Pydantic class IEMAPProject is provided to easily build and validate project metadata.
For more information and usage example view examples.py.
Alternatively, you can use ProjectHandler.build_project_payload() method to build a project payload from a Python dictionary.
IEMAP website provides a user-friendly interface to interact with IEMAP platform,
including the ability to add new projects, search for existing projects, and more.
In IEMAP website, projects metadata are defined compiling an Excel file (a template ready to use is provided) with the required fields,
this data are converted into a JSON object that is used to store the project metadata on the platform,
similarly to the schema above.
In a second step, files related to the project can be uploaded, always using the UI provided by IEMAP website.

Usage

This module allows you to interact integrate into your workflow the IEMAP platform. Data to store on IEMAP platform are stored as projects metadata and files,
this means that you can store metadata and files related to your projects. Steps required to use the module are:

1. Initialize the client
2. Authenticate (to get the JWT token used for subsequent requests). To register an account visit IEMAP.
3. Store metadata for your project
4. Store files related to your project
5. Retrieve/Query project data

Note: The module is designed to be used asynchronously,
so you should use async functions and await for making requests. A quick introduction to asynchronous programming in Python can be found here.

Note:
IEMAP platform is a service provided by ENEA,
the Italian National Agency for New Technologies,
Energy and Sustainable Economic Development within the Project IEMAP (see details).

Here are some brief examples of how to use the iemap-mi module.

Initialize the Client and Authenticate

Fetch Paginated Project Data

# import necessary modules
import asyncio
from iemap_mi.iemap_mi import IemapMI


# define an async main function
async def main():


# Initialize IEMAP client
client = IemapMI()

# Authenticate to get the JWT token
await client.authenticate(username='your_username', password='your_password')

# Fetch paginated project data
projects = await client.project_handler.get_projects(page_size=10, page_number=1)
print(projects)

# Run the main function asynchronously
if __name__ == "__main__":
    asyncio.run(main())

Running Tests

To run the tests, use pytest. Make sure to set the TEST_USERNAME and TEST_PASSWORD environment variables with your test credentials.

export TEST_USERNAME="your_username"
export TEST_PASSWORD="your_password"
pytest
