This challenge demonstrates how XBRL’s existing reference mechanisms can be applied to capture extra metadata (for example cross-cutting categories such as “risk”) and use those in analysis.
The use-case specifies meta-data for two areas – ESG Topic and Disclosure Pillar for taxonomy concepts. ESG Topic can be identified as Environmental, Social or Governance for taxonomy concepts. Similarly, concepts can also be identified based on Disclosure Pillar as Strategy, Implementation or Performance measurement.
Reported sustainability data can then be analysed using this meta-data (“cross-cutting themes”):
Sample Taxonomy / Reports – Taxonomy using reference structure to capture meta-data reports referencing the taxonomy.
