How can we develop interoperable, decentralized digital infrastructures that allow for relational data storage while maintaining accessibility for the specific communities they serve?
“How can we develop interoperable, decentralized digital infrastructures that allow for relational data storage while maintaining accessibility for the specific communities they serve?”
Inspired by “How could 'living' digital archives be designed to reflect the non-static, oral traditions of Indigenous cultures without relying on the rigid, binary logic of current computing architectures?” →Summary
The exploration revealed that bridging relational databases with decentralized infrastructures relies on two distinct but complementary approaches: federated SQL-like platforms such as Kwil, which manage the storage layer, and provenance-based interoperability frameworks like PROV-IDEA. It was surprising to find that while decentralized storage (like IPFS) handles the 'decentralized' requirement, maintaining relational integrity across these distributed systems requires a formal metadata layer—specifically the W3C PROV-DM standard—to track schema evolution. This ensures that even when data is fragmented across decentralized nodes, the history and structure of that data remain verifiable and interpretable by different stakeholders. Ultimately, while we have effective tools for schema consistency and storage, the 'accessibility for specific communities' remains a complex governance challenge. The research suggests that technical interoperability (via provenance) is a prerequisite for, but distinct from, the community-centric access control that is typically managed via decentralized identity (DID) systems. The convergence of these fields remains an open area of architectural design.

I am investigating how to build decentralized, relational digital infrastructures that remain accessible to specific communities. I need to bridge the gap between traditional SQL-based relational models and decentralized storage architectures.

The Web3DB architecture proposes using decentralized storage (like IPFS) for the data layer while maintaining SQL-like operations, specifically addressing the challenge of fine-grained access control in multi-tenant decentralized environments.

I need to consider how schema evolution and interoperability are maintained in these systems, as decentralized data often suffers from fragmentation. The PROV-IDEA approach suggests using provenance standards to ensure schema interoperability over time.

Searching for how PROV-IDEA specifically handles the 'decentralized' aspect of data storage, as the initial research focused on relational database evolution.

PROV-IDEA focuses on the interoperability of provenance information across heterogeneous systems using PROV templates, which allows different databases to share a common language for evolution history, even if their underlying storage is decentralized.

The W3C PROV standard provides a core data model (PROV-DM) that enables systems to exchange provenance information, which is critical for maintaining consistency in decentralized environments where multiple parties manage data.

While PROV-IDEA solves the interoperability of schema evolution, it does not inherently solve the 'accessibility for specific communities' requirement; this likely requires an additional layer of decentralized identity (DID) or access control integrated with the provenance records.

Developing community-specific decentralized infrastructure requires stacking three distinct layers: a decentralized storage/SQL layer for relational data, a W3C PROV-compliant layer for schema interoperability, and a DID-based access control layer for community governance.
