The Insights schema
When i2 Insights imports data, it normalizes it into its own internal schema, a fixed set of entity and link types that represent the key concepts found across supported data sources (CDR, ANPR, transactions, and so on).
This schema is used to power the chart, maps, and analytics views inside Insights, and is also what gets sent to Analyst's Notebook when creating a chart.
Insights defines a set of built-in entity and link types. These are consistent regardless of which data source or provider you import from.
Entity types include:
Type | Represents |
|---|---|
| phone | A phone number (subject or contact) |
| person | A person attributed to a phone |
| organization | An organization attributed to a phone |
| imei | A mobile device identifier |
| server | A data communications endpoint |
| licensePlate | A vehicle license plate (ANPR) |
| licensePlateCamera | An ANPR camera location |
| genericEntity | A generic entity for data imported using the Generic Template |
Link types include:
Type | Represents |
|---|---|
| call | A communication event (voice, SMS, data, etc.) |
| attribution | A person or organization linked to a phone |
| usedIn | A phone linked to a device (IMEI) |
| vehicleSighting | A license plate sighted at a camera |
| genericLink | A generic link for data imported using the Generic Template |
Each type carries a set of typed fields. For example, a call link has startTime, endTime, and callType.
