Launch of the Pilot Infrastructure

This document provides a detailed overview of the first deliverable of Work Package 5 (WP5) entitled "D5.1 Launch of the Pilot Infrastructure", which is part of the OpenWebSearch.eu project. This project is funded by the European Commission under the grant agreement GA 101070014 within the Horizon Europe Framework Program. The "OpenWebSearch Federated Data Infrastructure" (OWS-FDI) spans five data centres, each playing interconnected roles. The document describes in detail the development and current state of implementation, including key metrics. It also defines the relationship of the infrastructure to other work packages that benefit from this setup. The discussion covers the stages from the initial proposal to the current state of implementation and also future plans for the remainder of the project.
