Every taxonomy. Maintained, versioned, and ready.

Comprehensive taxonomy library. We maintain a continuously updated library of regulatory taxonomies across all supported jurisdictions. You access the correct, current version of the taxonomy you need, without managing downloads, version conflicts, or local caches.

Full taxonomy introspection via API. The Semansys API exposes the complete structure of any supported taxonomy: entry points, schema sets, presentation linkbases, calculation linkbases, definition linkbases, label resources, and concept-level metadata. This enables downstream applications to build dynamic reporting forms, perform data mapping, and enforce taxonomy constraints programmatically, without embedding static taxonomy artefacts.

Taxonomy extension support. Regulators and listed companies frequently need to extend standard taxonomies with company-specific or jurisdiction-specific concepts. Our platform supports the full XBRL extension taxonomy pattern (new concepts, new link roles, new presentation relationships, and pivot tables) and validates extension documents against both the base taxonomy and the extension constraints defined by the relevant regulator.

Table and presentation rendering. Taxonomy presentation linkbases encode the intended layout of financial statements and disclosure tables. We resolve these structures and expose them as rendered table definitions, enabling applications to generate correctly structured data-entry forms or disclosure previews directly from the taxonomy, with no manual layout work required.

Calculation and definition linkbase access. Calculation linkbases define the arithmetic relationships between reported facts. Definition linkbases define dimensional structures and hypercubes. Both are exposed through the API with full navigational fidelity, supporting advanced use cases such as automated cross-validation, dimensional data modelling, and comparative analysis.

CSV export for data mapping. Taxonomy concept sets, including dimensional placeholders, can be exported in CSV and ZIP formats, providing a practical bridge between the taxonomy and the spreadsheet-based or database-driven data pipelines that most organisations use to assemble reporting data.

Entrypoint discovery. For any supported taxonomy, the platform returns the full set of available entry points with their associated metadata, parameters, and table-of-content structures, giving integrating applications an accurate, up-to-date map of what can be filed and where.
