ADP 2.0: Modernizing Technical Infrastructure with Dataverse and e-Storage applications

In 2025, the Slovenian Social Science Data Archives (ADP) introduced two new applications into regular use: Dataverse as its research data repository and the e-Storage app as its digital preservation system.Dataverse replaces the legacy Nesstar platform and streamlines ingest services, simplifying the deposit and dissemination of research data. Features, including an integrated deposit agreement and expanded metadata fields with controlled vocabularies, enhance usability and compliance. ADP also introduced a self-deposit model, offering a lighter curation option for datasets with lower quality or limited reuse potential.The e-Storage app supports professional digital preservation practices by ensuring systematic provenance tracking, authenticity checks, traceability, and version control. API integration between Dataverse and e-Storage, currently under development, will enable automated transfer of both data and metadata, further optimizing ingest and publication workflows. Both Dataverse and the e-Storage app are built around DDI standards, ensuring consistent metadata structure and interoperability across ADP's data services.A redesigned ADP website complements these services, offering improved access to resources, training materials, updated content, and a refreshed visual identity. Metadata are openly available for harvesting via the OAI-PMH protocol, including the DDI Codebook format, supporting discoverability.This presentation will outline ADP's modernization path, highlight the challenges of migration and integration, and demonstrate how ADP is building sustainable, user-friendly, and future-oriented data services that meet the evolving needs of research data management.
