About These Vocabularies

These vocabularies define the semantic layer of the Locorda Sync Engine. They enable:

  • Interoperability: Different applications can understand and process each other's synchronized data
  • Transparency: All synchronization metadata is stored as standard RDF triples
  • Extensibility: Applications can add custom properties while preserving core sync functionality

CRDT Algorithms Vocabulary

A vocabulary defining merge algorithms and strategies for state-based CRDTs on RDF data. These algorithms specify how conflicting values should be resolved during synchronization.

CRDT Framework Mechanics Vocabulary

A vocabulary defining the low-level operational mechanics and infrastructure properties required for CRDT synchronization coordination, including hybrid logical clocks, installation management, and deletion handling.

Locorda Google Drive Backend Vocabulary

Vocabulary for mapping semantic RDF types to Google Drive folder structures in the locorda CRDT synchronization framework.

Indexing Vocabulary for CRDT Sync

A vocabulary to describe the structure, configuration, and conventions of indices used for performance and discovery in a offline-first, CRDT-based synchronization system.

CRDT Merge Contract Definition Language

A vocabulary for defining merge contracts and mapping rules for CRDT synchronization.

Solid Backend Integration for CRDT Sync

Solid-specific integration vocabulary that provides mappings and aliases for using the core CRDT sync framework with Solid Pods. This vocabulary does not define new concepts but provides Solid-specific interpretations of core framework concepts.
