For Infrastructure Managers, keeping the registry in sync with reality is the biggest challenge. RINF 3.1 introduces two concepts to handle time:
1. Validity Dates
Scope: The Object Itself
Defines the lifespan of a physical object.
- Start Date: When the asset is commissioned/built.
- End Date: When the asset is decommissioned/removed.
Example: "This bridge exists from 1950 to 2050."
2. Applicability Periods
Scope: Specific Parameters
Defines when a specific value (like speed limit) is valid.
- Allows parameters to change without deleting the object.
- Used for temporary restrictions or planned upgrades.
Example: "Speed limit is 100km/h until June, then 120km/h."
Temporal Features
All of this is powered by the standard Time Ontology. Intervals are defined clearly, allowing the system to answer questions like:
- "Show me the network as it will be in 2026."
- "Was this track available for freight matching these parameters last Tuesday?"
