About ACRIS Semantic Model

The organisation and accessibility of large volumes of data is a cornerstone strategic objective of any modern airport.

The ACRIS Semantic Model was created to capture, represent and specify the airport community’s common knowledge in a standardised and accessible manner.

The ACRIS Semantic Model has a number of layers, comprising the airport vocabulary of business terms.

The knowledge layer contains the main concepts that are of interest to an airport and its partners. The data element library layer contains detailed information on the data items, including standard naming conventions. A technology realisation layer represents the components such as message interface schemas (e.g. XML Schema Definitions (XSDs) or JSON schemas), data models for information exchange (e.g. Resource Description Framework (RDF)), rich semantic languages (e.g. Web Ontology Language (OWL)) and database schemas.

The ACRIS semantic model enables the specification of re-useable information services (ACI-ACRIS Services) across the Airport community. The Semantic Model has enabled the completion of initiatives such as standard definitions for Self bag drop, Seamless Travel, A-CDM (Airport Collaborative Decision Making), Airport maps and others.

The ACRIS semantic model provides an organising framework based on IT industry best practices and ISO standards for documenting the Airport ecosystem’s vocabulary, knowledge, re-usable standard information components and data structures.

Airports developing Open APIs and common use Apps are encouraged to base their definitions on the ACRIS semantic model, in order to promote interoperability and connectivity. The ACRIS model is fully aligned with IATA’s AIDM model where elements are common.
