scope:

The purpose of this CWA is to propose a standard for submitting data instances to financial regulators in accordance with the chapter describing this CWA in the business plan [26]: ""Metadata container" to wrap a submitted XBRL instance document and compliance test.

Metadata are needed as well for financial reporting as for company legal and economical data. For the digital signature, existing solutions from the Business Registers, who have a deep expertise of the topic, may be generalized. In order to ensure compliance with the protocol, this project will deliver online tools for all stakeholders to use and to test compliance with the complete set (metadata container and XBRL instance document. This CWA will provide standard protocols and mechanisms for digital signature, administrative data such as identification of submitter, feedback parameters, versioning of subsequent submissions and encryption, as well as online collaborative tools to ensure compliance." This document specifies:
- a submission container structure to enable financial institutions to submit their regulatory reporting to the respective regulators in a standardised way;
- a metadata information structure (called « Header ») that is part of the submission container structure;
- an ade ...
