Concept: deposit article and check metadata in public (scholarly) databases

Concept for publication of certificate metadata into other scholarly infrastructures and meaningful open research information (e.g., DataCite, CrossRef, Wikidata).

As part of the concept, create flow-diagrams and plenty of mock-ups. Then we discuss features and create new issues for every data sink.

**Important:** This plugin could possibly be extended to pick up codecheck metadata if it exists and then handle the export: https://github.com/saddamalsalfi/ojs-quickstatements-export

----------

**User story:**

- _As the codechecker, I want OJS to deposit the certificate and metadata automatically, so that I don't have to do it manually and make no mistakes._
- _As the publisher, I want to formalize the CODECHECK process and include metadata in metadata records/depositions, so that I guarantee data and software FAIRness and increase visibility of my own journal._
- _As a publisher, I want the plugin to connect with the CODECHECK infrastructure for publication of certificates and metadata without my staff/my editors having to do work on other tools/platforms, so that it is guaranteed that the CODECHECK follows the CODECHECK principles and requirements._
