We track the development of the relevant metadata schemas including their documentation in the openCost GitHub repository. It can be accessed at the following link:
In addition to a tabular description of the schema, it also contains FAQs, an XSD file for formal verification, and a folder with sample files that fulfill the metadata schema.
Since we want to involve the community in our work as early as possible, we decided to publish our project results successively, always asking for feedback. Therefore, we invite you to participate in the development of the metadata schema and look forward to a constructive discussion. Please feel free to open issues in the GitHub repository so we can address your suggestions easily and nothing gets lost. Alternatively send us feedback by email.
