Still to come

  1. The XBRL ReportTake an XBRL report apart into facts, contexts, units and decimals, and learn what each one must state before a tagged number means anything.
  2. Concepts and SchemasPick the right XBRL concept for a line item, read a taxonomy schema, and spot the tag that quietly reports something other than what the row says.
  3. LinkbasesWork out which XBRL linkbase controls presentation, calculation, labels, definitions or references, and what breaks in a filing when one of them is wrong.
  4. DimensionsRead a dimensional XBRL fact with its axes, members and typed dimensions, and see why a total can legitimately disagree with the rows above it.
  5. Inline XBRLFind the inline XBRL tags inside a rendered iXBRL document, and tell a properly tagged figure from one that only looks tagged.
  6. Validation and ErrorsTrace an XBRL validation error back to the fact that caused it, from a calculation inconsistency to an xbrldie dimension error. This chapter turns a validation report into a short list of things to fix.
  7. Taxonomies in the WildTell the Dutch SBR, ESEF, IFRS and US-GAAP taxonomies apart, and find which entry point and filing rules your annual report is judged against.
  8. Extensions and AnchoringDecide when a filing needs an XBRL extension element, and anchor it to the base taxonomy so the report stays comparable.
  9. Reviewing Tagged Filings in PracticeReview a tagged iXBRL annual report at speed, open an .xbri package in a reader, and make sure real validation errors get fixed instead of plausible-looking ones.
