\section{Conclusions}

This thesis has presented the design, implementation, and evaluation of a unified platform for experimental data access and documentation in the context of the RFX-mod2 experiment, which aims to study the physics of fusion plasmas and magnetic confinement in Reversed Field Pinch (RFP) configuration.

The evolution from RFX-mod to RFX-mod2 has brought substantial upgrades to the experimental infrastructure. These include modified mechanical components, an updated electrical configuration, and a more advanced CODAS (Control, Data Access, and Communication Systems). In addition to improving operational performance and machine reliability, these enhancements significantly expand the range of available diagnostics. This increased data richness provides deeper insight into plasma phenomena but also introduces the complex challenge of efficiently managing, accessing, and interpreting large volumes of data.

To address these challenges, this work has developed a unified platform that integrates two core components:

\begin{itemize}
    \item \textbf{Experiment Logbook Management:} A web-based application designed to manage semantic information, enabling researchers to efficiently document, retrieve, and contextualize experiments. By incorporating detailed logbook entries, this system enriches raw diagnostic data with experimental configurations, objectives, and observations, supporting reproducibility, collaboration, and cross-experiment analysis.

    \item \textbf{Scientific Data Access:} The Query Engine system was developed as a framework for efficient, scalable data access and analysis of experimental data. This component allows researchers to construct, manage, and reuse data processing logic across multiple shots, streamlining access to a large volume of diagnostic data and supporting advanced data analytics workflows.
\end{itemize}

The results of performance evaluations highlight the Query Engine's efficiency and scalability across different deployment configurations, demonstrating its potential to handle the increasing data demands of RFX-mod2 experiments effectively. By integrating these two components, the unified platform provides a more accessible and integrated framework for managing and analyzing experimental data, ultimately improving the efficiency and reliability of the entire research workflow.

\section{Future Works}
While the unified platform has addressed the key challenges identified in this thesis, several avenues for future work remain:

\begin{itemize}
    \item \textbf{Organizing the Experiment Hierarchy:} Establishing a more effective structure for the experiment hierarchy by organizing entries such as experiments, campaigns, runs, and shots will be essential. This could be reflected in a RESTful API structure to provide consistent and predictable access patterns across the platform.

    \item \textbf{RESTful Query Management:} Exposing queries via REST endpoints with clear, unique names would simplify integration with external systems, particularly for retrieving summaries. However, this requires careful consideration of naming conventions to avoid confusion and ensure consistency.

    \item \textbf{Collaborative Logbook Input:} Enabling collaborative editing for logbook entries, including real-time multi-user input, will enrich experiment documentation and support dynamic workflows.

    \item \textbf{Flexible Structures of Logbook Entries:} Since experimental requirements can evolve rapidly, future work should include support for defining flexible structures and fields within logbook entries to effectively accommodate these changes.

    \item \textbf{User-Specific Views:} Supporting role-based front-end views for each user will make the system more intuitive and tailored to individual workflows.

    \item \textbf{Content Identifiers for Queries:} Introducing Content Identifiers (CIDs)~\cite{ipfsContentAddressing} for queries can reduce duplication, improve traceability, and support robust verification mechanisms -- particularly important for tracking changes to MDSplus data.

\end{itemize}

In summary, the unified platform developed in this thesis represents a significant step toward addressing the challenges of managing and analyzing the growing volumes of data produced by plasma physics experiments. By integrating semantic documentation with efficient data access, it provides a foundation for more advanced data analytics and collaborative research, paving the way for future improvements and scientific discoveries in the RFX-mod2 experiment and beyond.
