XBRL International Publishes First Public Working Draft of Next-Generation XBRL Specification

XBRL International Publishes First Public Working Draft of Next-Generation XBRL Specification

XBRL International has published the first Public Working Draft of Project Tavi, its initiative to develop the next generation of the XBRL specification.

Approved for publication by the XBRL Standards Board, the draft explores a simpler approach to modelling and digitising business reports while retaining the fundamental concepts that make XBRL structured and machine-readable. As an initial working draft, the specification remains subject to change and has been released to gather broader industry feedback.

What Is Project Tavi?

Project Tavi is the temporary name for XBRL International’s next-generation XBRL initiative.

The project is examining how the XBRL specification can be made simpler and easier to work with using modern development technologies, while preserving the semantic structure required for reliable digital reporting.

The draft introduces a simplified data model currently represented in JSON, with fewer technical components than the existing specification stack. The aim is to make structured reporting data easier to work with using commonly available developer tools.

Project Tavi is currently a working draft rather than a final specification, and its formal name is expected to be announced later.

What Is Changing in the Proposed Model?

The first Public Working Draft introduces several areas of simplification.

Key developments include:

1.A simpler data model designed to reduce technical complexity.
2.JSON-based representation in the current draft, making the model more accessible to modern development environments.
3.Continued use of core XBRL concepts such as concepts, dimensions, and data constraints.
4.Simplified terminology across the specification.
5.Integration of registries for units, data types, and link roles directly into taxonomies.
6.Example models and draft conformance suites that allow developers and stakeholders to experiment with the proposed approach.

The draft also considers how modern AI tools can interact more directly with taxonomies and structured reporting data. XBRL International notes that capable general-purpose AI tools can read the proposed taxonomies, answer questions about them, and work with the associated data.

XBRL 2.1 Is Not Being Replaced

One of the most important points for reporting organizations is that the publication of Project Tavi does not create an immediate migration requirement.

XBRL International has explicitly stated that the existing XBRL 2.1 specification stack is not being deprecated. Existing taxonomies and filings remain valid, there is no migration deadline, and organizations are not currently required to adopt the proposed framework.

The current publication should therefore be viewed as an indication of the potential future direction of the XBRL standard rather than a change to existing filing obligations.

Why Does This Matter for Digital Reporting?

Business reporting requirements have expanded significantly since the original XBRL specifications were developed. Structured reporting now supports regulatory filings across multiple jurisdictions, increasingly complex taxonomies, digital financial statements, and growing demand for machine-readable information.

At the same time, reporting data is being consumed by a wider range of technologies, including analytics platforms and AI-enabled applications.

A simpler underlying specification could make it easier for software developers, regulators, and reporting ecosystems to build, exchange, and analyze structured information while preserving the semantic meaning embedded in XBRL.

For reporting teams, however, the immediate priority remains compliance with the taxonomies, technical specifications, and filing rules currently required by the relevant regulator.

What Should Reporting Organizations Do Now?

No immediate system or filing changes are required as a result of the Public Working Draft.

Organizations involved in structured reporting can instead:

1.Monitor the development of the next-generation specification.
2.Review future drafts and technical documentation as they become available.
3.Assess how potential changes could affect existing digital reporting architectures over the longer term.
4.Continue preparing and validating regulatory filings according to currently applicable XBRL and Inline XBRL requirements.

XBRL International is inviting feedback on whether the proposed direction is appropriate, what may be missing, and where further simplification may be possible.

Ez-XBRL: Supporting Structured Reporting as Standards Evolve

As digital reporting standards continue to develop, reporting organizations need processes that can adapt to changing taxonomies, validation requirements, and regulatory specifications without compromising reporting quality or control.

Integix

Integix is Ez-XBRL’s AI-native digital and regulatory reporting platform for preparing XBRL and Inline XBRL reports across global reporting requirements. It brings document preparation, tagging, automation, validation, collaboration, and regulatory reporting workflows into a unified environment.

XOR

For structured review and validation, XOR provides a secure, collaborative environment for reviewing XBRL and Inline XBRL reports, running validations, managing comments, and supporting controlled approvals.

Ez-XBRL has extensive experience in structured data reporting and analytics, and we have multiple US patents utilizing structured data formats such as XBRL, XML, and JSON.

Together, these capabilities support a broader digital reporting process in which reporting information can move from preparation and review through validation and regulator-ready structured output.

Ez-XBRL continues to monitor developments in global XBRL standards, including Project Tavi, as the digital reporting ecosystem evolves toward the next generation of structured, machine-readable reporting.
