Inside Thing in the future
A multi-scale graph for WoT information mediation
Nodes of the graph store digital representations (a.k.a.avatars/twins/shadows) of connected and non-connected :
- things, objects, devices, spatial entities, physical systems and their subsystems at all scales
- high-level « property graph » meta-model
- nodes have properties, relationships may have properties
Semantic referencing of graph, ab initio OR post hoc
- All nodes, relationships and properties are :
- uniquely identified by URIs
- part of larger linked data cloud
- typed with reference to :
- Standardized cross-domain information model
- External domain-specific ontologies
- uniquely identified by URIs
High-level and effective navigation & query language
- Geospatial query
- Graph matching (e.g. finding patterns in the graph, a subgraph in the graph)
Access modalities
- Interfaces to networked functionalities of physical devices from Thing in
- With pricing and contracts if they apply
Built-in security & privacy
- Data from physical objects is sensitive….
- Thing in does not store raw data streams generated by all sensors and data sources it will reference
- Thing in partners manage their own access rules
