CoreFiling provided full-time, expert resources to the XBRL Rendering Working Group to revise and rewrite the stalled table linkbase specification at a time when European regulators were having difficulties developing implementations because of the incomplete state of this key standard. At substantial cost, CoreFiling took over the editorship of the specification and contributed substantial intellectual property in the form of conformance suite tests and other work, in order to push the specification to a successful completion. This work involved a number of CoreFiling staff over a long period of time, engaged in development and prototyping of the standard, editing and proving of the specification, schemas and tests, and promotion and support of the standard in industry forums and working groups.
