Filing indicators (current discussions among Supervisors). Topic described more or less as follows:

  • Filing indicators are facts included as part of an instance document where the filer estates which tables are being reported. Filing indicators should not be part of the dictionary of concepts. They are just technical artefacts.
  • Filing indicators being a “generic sub-element” of a tuple (or dimension) or a concept? Filing indicators must be first class citizens or generic values of a fact?
  • Supervisors would need the (boolean) filing indicators to be accompanied by an indication of why a particular template was not filed, in order to distinguish between, for example, where an entire line of business is not conducted by an undertaking vs. where they feel they are not required to report as their level of business falls/fell below some proportionality threshold. Is the information related to proportionality, materiality, zealous filing… typically covered by foot-notes on filing indicators (any fact may be associated to one or more foot-notes)?
  • If the filings indicators are defined using concepts (aka primary items), and considering than each concept is to be defined in the taxonomy, then each new filing indicator would result in a modification of the “content definition” of the taxonomy. However, if the filing indicators are defined using instantiations of repetitive structures (as tuples or dimensions), the “content definition” of the taxonomy is unaltered. Only the specific formulae for validation is to be updated. But this have no impact in the structure of data. This “golden rule” of isolation between “data structures” and “validations “ is inspired in the paradigm “Algorithms Plus Data Structures Equals Programs” of Niklaus Wirth
  • Facts are used, defined at the template level. The template level is the one on which the legal requirement (including proportionality waivers) are based. From a business point of view, a template is the granularity level on which a number of business rules apply. Filler to express which subset of the requirement they are reporting for (this means that it is something that should be in the instance itself, and not only in the envelope). This subset can be rendered (e.g. as a summary or cover template). From this point of view, a change in the “filing indicators” is linked to a change in the business requirements (required granularity, or content), and so probably mandate an update of the taxonomy.
  • What exactly is the (part of) business problem(s) to be solved: Controlling the execution of validations? Submissions follow-up/ monitoring reporting obligations? What is the required granularity for this control?
