XBRL Table Linkbase specification

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.

Inline XBRL specification

CoreFiling devised the original concept of Inline XBRL (iXBRL), developed it and promoted it through the XBRL International working group process. The work on iXBRL included: working through the original innovations, promoting and arguing the case in the international XBRL community, building the specification and liaising with government departments to ensure that it would be consistent with their long term needs.
