The capability of different systems to exchange data and consistently interpret and use the information exchanged.
DESCRIPTION
Data interoperability ensures systems can exchange, understand, and reuse data consistently. It spans syntactic, semantic, and organizational layers. Standards, controlled vocabularies, and APIs enable consistent formats and meaning. Interoperability reduces integration costs, avoids vendor lock-in, and improves data sharing. Approaches include open standards like DCAT, RDF, and JSON Schema, plus domain standards like HL7 FHIR. Governance and metadata management provide alignment and trust.
ALTERNATIVE DEFINITIONS
W3C
Interoperability is the ability of systems to exchange and make use of information.
Highlights both exchange and effective use, not just transport.
ONC (HealthIT.gov)
Interoperability refers to the ability of a system to exchange electronic health information with other systems and to use the information that has been exchanged.
Focuses on health data but generalizes to exchange and use of information.
European Commission
Interoperability is the ability of organizations to interact and share information and knowledge, through the exchange of data between their ICT systems.
Adds organizational dimension and cross-organization interaction.

TOP QUESTIONS
Why is Data Interoperability critical for modern organizations?
It lowers integration costs, enables data sharing, and reduces vendor lock-in, accelerating analytics and innovation.
Category: Relevancy
What are the levels of Data Interoperability?
Syntactic (formats), semantic (meaning), and organizational (process/policy) interoperability together enable reliable exchange and use.
Category: Overview
What standards improve Data Interoperability?
DCAT, RDF/OWL, JSON Schema, OpenAPI, and domain-specific standards like HL7 FHIR are widely used.
Category: Best practices
What are common mistakes in Data Interoperability programs?
Ignoring semantics, underinvesting in metadata, and bespoke integrations that bypass standards create fragile, costly ecosystems.
Category: Mistakes
What risks arise without Data Interoperability?
Data silos, inconsistent metrics, and duplicated effort hinder analytics, compliance, and collaboration.
Category: Risk
How does Data Interoperability relate to data contracts?
Contracts formalize schemas and expectations, providing enforceable interfaces that improve interoperability across teams and domains.
Category: Relationship
Which roles should lead Data Interoperability efforts?
Data architects, stewards, and governance leaders coordinate standards, metadata, and integration patterns across domains.
Category: Management
How do knowledge graphs support Data Interoperability?
They encode shared semantics and relationships, enabling consistent interpretation across systems and contexts.
Category: Example
Where to start with Data Interoperability?
Identify critical data products, define canonical schemas and vocabularies, and adopt open standards with governance.
