Data Management System
A huge quantity of data has been acquired since the inception of the Pietragalla Project, both in the museum and on site. The pieces of this documentary puzzle converge in a data management system.
The core of the data management system is built using OMEKA S, an open source content management system, which serves as the backbone for managing and analyzing the diverse datasets generated by the Pietragalla Project and leverages APIs to aggregate and harmonize data from multiple sources, including structured data (MySQL databases, GIS), digital images (photos, orthophotos, digitized plans, photos and drawings, vector images), documents (archives, hand-written field logs), and digital media (3D models, drone images).
The data management system pays particular attention to provide accurate metadata to promote the reuse of our datasets through persistent identifiers (DOIs). To ensure the sustainability and accessibility of the datasets, the project deposits its data with repositories hosted by Huma-Num, the French national infrastructure for humanities research. This includes: Nakala (for the datasets including structured data, images, and documents) and the Conservatoire National des Données 3D (for 3D models and associated metadata and paradata). Both guarantee permanent preservation of our datasets, align with the FAIR principles of open science, and support the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), providing advanced visualization and query capabilities to facilitate research and data dissemination. The data management system supports the long-term goals of the Pietragalla Project and its commitment to open science.
Except for Ranaldi’s (†1988) and Adamesteanu’s (†2004) archives, which are still covered by European copyright laws, the datasets are placed in the public domain with an Etalab licence, the French open data license that allows free and unrestricted reuse, modification, and commercial exploitation of public information from French state administrations, requiring only attribution to the source and compliance with French law. It is designed for broad compatibility with international standards like CC-BY, encouraging transparency and widespread use of public data.
