Glossary

A

API (Application Programming Interface) A set of protocols and tools for building software applications. TimeTiles provides a REST API for programmatic access to data import, query, and export functionality.

Audit Log A system that records user and admin actions for accountability and debugging. TimeTiles tracks 20 action types across 5 domains: account, admin, data, system, and ingest.

C

Catalog The top-level container for organizing related datasets. Each catalog represents a project or workspace with its own access control and branding.

Clustering The automatic grouping of nearby events or data points to improve visualization clarity and performance. TimeTiles clusters both spatially (by location) and temporally (by time).

CSV (Comma-Separated Values) A file format used to store tabular data. One of the primary import formats supported by TimeTiles.

D

Data Export A self-service feature allowing users to download all their data (catalogs, datasets, events, import history) as a ZIP archive from Account Settings.

Data Ingestion The process of bringing external data (CSV, Excel, ODS, JSON API, or scheduled URLs) into TimeTiles. The ingestion pipeline handles schema detection, deduplication, geocoding, and event creation. Called “Import” in the user interface and ingest-* in the codebase. See the Data Import guide and the developer pipeline documentation.

Dataset A collection of related events within a catalog. Datasets share a common structure (schema) and represent a specific data source or time period.

Dynamic Filters Interactive controls that allow users to filter and explore data in real-time without page reloads. Includes time range, location, and custom field filters. State is synced to the URL via nuqs.

E

Event A single data point in TimeTiles representing something that happened at a specific time and place. Events are the basic building blocks of datasets.

F

Feature Flag A toggle that enables or disables platform capabilities (e.g., public registration, scheduled imports, event creation). Configured in Settings (/dashboard/globals/settings).

G

Geocoding The process of converting addresses or place names into geographic coordinates (latitude and longitude).

GeoJSON A format for encoding geographic data structures using JavaScript Object Notation (JSON).

Geospatial Data Information that includes location data (coordinates, addresses, place names) along with other attributes.

Global (Payload) A site-wide singleton configuration in Payload CMS. TimeTiles uses four globals: Branding, Footer, MainMenu, and Settings.

I

Import Pipeline See Data Ingestion. The user interface uses “Import” for this concept; the codebase uses ingest-* collection and variable names.

J

JSON (JavaScript Object Notation) A lightweight data-interchange format that’s easy for humans to read and write.

M

Map Clustering The visual grouping of multiple events that are close together geographically to prevent overcrowding on the map interface. Uses PostGIS for server-side aggregation.

P

Payload CMS The content management system used by TimeTiles for managing data, users, and configurations. Version 3, integrated with Next.js.

PostGIS A spatial database extension for PostgreSQL that adds support for geographic objects and spatial queries.

PostgreSQL The open-source relational database system used by TimeTiles, enhanced with PostGIS for geospatial capabilities.

R

React Query A library for managing server state in React applications. Used by TimeTiles for efficient data fetching, caching, and synchronization.

S

Scheduled Ingestion An automated URL-based data ingestion that runs on a cron schedule. TimeTiles fetches data from a URL at configured intervals and processes it through the ingestion pipeline. Called “Scheduled Import” in the user interface.

Schema Detection The automatic process of analyzing uploaded data to identify date fields, coordinate fields, and other important columns without manual configuration.

Site A multi-tenant configuration unit in TimeTiles. Each site can have its own branding, domain, and content settings. Managed via the Sites collection.

Spatial Query A database query that involves geographic locations and relationships between them.

T

Timeline Navigation The interface controls that allow users to move through time, including play/pause controls, time range selection, and temporal zoom.

Temporal Data Information that includes time-based attributes, showing when events occurred.

Trust Level A user permission tier (0–5) that controls rate limits, quotas, and access to platform features. Higher trust levels unlock greater API usage and import capacity.

Turbopack A fast bundler for JavaScript and TypeScript, used by Next.js 16 in TimeTiles for improved development performance.

U

URL Parameters Web address parameters that store filter and view states, allowing users to share specific views of their data.

V

View A saved display configuration for exploring data. Views define which datasets are shown, map bounds, active filters, and layout preferences.

Visualization The graphical representation of data, including maps, timelines, charts, and interactive elements that help users understand patterns and relationships.
