SDKs overview

Open Government, Greece provides developers with Software Development Kits (SDKs) and client libraries to streamline interaction with its various public data and service APIs. These tools abstract the underlying RESTful API calls, handling authentication, data serialization, and error handling, allowing developers to focus on application logic rather than low-level HTTP requests. The official SDKs are designed to offer a consistent and robust experience for accessing the Open Government, Greece platform, supporting initiatives in government transparency and citizen engagement with public data. The use of SDKs can reduce development time and enhance code readability by providing idiomatic interfaces for common programming languages. Beyond official offerings, a vibrant community contributes additional libraries and tools, extending compatibility and niche functionalities.

Integrating with public sector data often involves adherence to specific data formats, such as JSON:API specifications or other structured data models. SDKs help in parsing and constructing these data structures correctly, mitigating common integration challenges. They typically include methods for searching datasets, retrieving specific records, and managing API request limits where applicable. Developers can use these SDKs to build web applications, mobile apps, data analysis tools, or automated reporting systems that consume information from various Greek government agencies.

Official SDKs by language

Installation

Installation of the Open Government, Greece SDKs follows standard package management procedures for each respective language. The process is designed to be straightforward, allowing developers to quickly integrate the SDKs into their projects.

Python SDK installation

To install the Python SDK, use pip, the Python package installer. Ensure you have Python 3.7 or higher installed on your system. The command below will fetch and install the latest stable version of the opengov-gr-python package and its dependencies:

pip install opengov-gr-python

After installation, you can verify it by attempting to import the package in a Python interpreter:

import opengov_gr
print(opengov_gr.__version__)

JavaScript SDK installation

For JavaScript projects, the SDK is available via npm (Node Package Manager). Ensure you have Node.js and npm installed. Navigate to your project directory and execute the following command to add the @opengov-gr/js-sdk package:

npm install @opengov-gr/js-sdk

If you are using Yarn as your package manager, the command would be:

yarn add @opengov-gr/js-sdk

Successful installation will add the package to your node_modules directory and update your package.json file, registering the dependency.

Quickstart example

This section provides quickstart examples for both the Python and JavaScript SDKs, demonstrating how to fetch a list of public datasets. These examples illustrate basic initialization and data retrieval methods, providing a foundation for more complex interactions.

Python quickstart

The following Python snippet initializes the SDK client and retrieves a list of the first 10 public datasets. It then prints the title and description of each dataset:

import opengov_gr

# Initialize the client
# No API key is required for public datasets, but can be configured for authenticated endpoints
client = opengov_gr.Client()

try:
    # Fetch a list of datasets
    # The 'list_datasets' method returns an iterable collection or a paginated response
    datasets = client.list_datasets(limit=10)

    print("--- Top 10 Public Datasets ---")
    for dataset in datasets:
        print(f"Title: {dataset.get('title', 'N/A')}")
        print(f"Description: {dataset.get('description', 'No description provided')[:100]}...") # Truncate description
        print("----------------------------")

except opengov_gr.exceptions.OpenGovGrAPIError as e:
    print(f"An API error occurred: {e}")
except Exception as e:
    print(f"An unexpected error occurred: {e}")

This example demonstrates error handling and basic data access patterns. For specific API endpoints and advanced query parameters, refer to the Open Government, Greece API reference documentation.

JavaScript quickstart

The JavaScript quickstart demonstrates fetching the same list of public datasets using the @opengov-gr/js-sdk. This example can be run in a Node.js environment or bundled for browser use.

import { OpenGovGrClient } from '@opengov-gr/js-sdk';

async function getPublicDatasets() {
  // Initialize the client
  const client = new OpenGovGrClient();

  try {
    // Fetch a list of datasets
    const response = await client.listDatasets({ limit: 10 });
    const datasets = response.data; // Assuming data is in a 'data' property for list responses

    console.log("--- Top 10 Public Datasets ---");
    datasets.forEach(dataset => {
      console.log(`Title: ${dataset.title || 'N/A'}`);
      console.log(`Description: ${dataset.description ? dataset.description.substring(0, 100) + '...' : 'No description provided'}`);
      console.log("----------------------------");
    });
  } catch (error) {
    if (error.response) {
      // The request was made and the server responded with a status code
      // that falls out of the range of 2xx
      console.error(`API Error: ${error.response.status} - ${error.response.data.message || error.message}`);
    } else if (error.request) {
      // The request was made but no response was received
      console.error("API Error: No response received from server.", error.request);
    } else {
      // Something happened in setting up the request that triggered an Error
      console.error("Error: ", error.message);
    }
  }
}

getPublicDatasets();

This JavaScript example utilizes ES Modules syntax and async/await for asynchronous operations, which is common in modern JavaScript development. Error handling in JavaScript typically involves checking the error.response for details on server-side issues, as demonstrated in the example.
