Eventsand

Eventsand is a term used in information systems to describe a standardized approach to modeling, exchanging, and discovering event data across diverse systems. It refers to a family of concepts rather than a single product, emphasizing interoperability, provenance, and composability of event information.

Core concepts of eventsand treat an event as an identifiable unit with fields such as id, type, and timestamp, accompanied by a source, a payload with domain data, and optional context like location or user, plus provenance metadata. The model supports extensible schemas and a minimal common core to enable cross-domain compatibility, while allowing domain-specific extensions.

In practice, implementations of eventsand often rely on JSON-based schemas and APIs that allow publishing, querying by type or time window, and filtering by source. A key aim is to enable deduplication, data minimization, and provenance tracking to support reliable event discovery and enrichment across systems. Interoperability is a central objective, so naming conventions and structural conventions are emphasized to facilitate integration between logistics platforms, cultural event calendars, sensor networks, and research datasets.

Applications of eventsand span a range of domains, including cultural and public events, logistics and supply chains, emergency management, and Internet of Things event streams. The concept also supports research contexts where historians or analysts aggregate events from multiple sources to study patterns and causality.

History and status: the term appears in discussions of data interoperability and event-driven architectures and is not tied to an officially ratified standard. Various projects propose similar schemas and patterns, but there is no universal specification under the name eventsand at present.
