What is ESEF iXBRL tagging automation?

It is tagging the annual financial report to the ESEF taxonomy inside the reporting model itself, validating every mapping continuously rather than in a final vendor pass.

Do we need an external tagging vendor?

No. Tagging happens in the same model that produces the statements, so no external round trip is required.

What happens when the taxonomy updates?

Taxonomy updates are applied centrally and existing mappings are re-validated, surfacing any tag that needs review.

Tagging that survives the last-minute edit

ESEF reporting automation moves inline XBRL tagging to where the numbers are born, so validation happens all year instead of failing at the deadline.

01The problem

ESEF tagging is usually bolted on after the report is finished, so every late edit breaks the tagging, restarts review and pushes validation into the final hours before submission.

The problem: ESEF tagging as an afterthought

Three reasons the last week of an ESEF cycle is the worst one.

Tagging starts after drafting

The report is written first and tagged second, so the two artefacts drift apart with every revision.

Late edits break the tags

A single changed table invalidates the tagging around it and sends the reviewed sections back to the start.

Dependency on a tagging vendor

Turnaround is set by an external queue, so the filing timetable is no longer yours to control.

The solution: DECIMA ESEF iXBRL tagging automation

DECIMA tags as it drafts, then validates continuously against the taxonomy.

Tagged at the source

Tags come from the model as the report is produced, so late edits inherit tagging instead of destroying it.

Continuous validation

Taxonomy and filing rules run on every change, ending the file-fail-retag-refile cycle.

Review a tag like a number

Reviewers see the tagged output next to the source figure, so tagging review stops being a specialist bottleneck.

How ESEF Reporting runs on the engine

Five stages that run continuously — not a quarterly scramble reassembled by hand.

01
Ingest
Governed connectors pull ledgers, sub-ledgers and source systems into the engine, with every field traced back to where it came from.
02
Model
The engine maps accounts, entities and disclosure requirements for ESEF Reporting into one live model instead of a set of linked files.
03
Draft
Narrative, tables and tagging are generated from the model, so a change in the numbers rewrites the output rather than the reverse.
04
Validate
Rule checks, tie-outs and control tests run inline as the draft forms, flagging breaks at the point they appear.
05
Sign off
Reviews, approvals and evidence are captured as work happens, so the audit trail for ESEF Reporting is complete the moment you file.

What changes

The measurable difference once ESEF Reporting stops being a manual assembly job.

01
Tags are applied from the model as content is written, so late edits leave tagging intact.
02
Validation runs continuously, so there is no file-fail-retag-refile cycle.
03
Reviewers see tagged output and source figures side by side, so tagging review is no longer a specialist bottleneck.
