For creating and managing metadata profiles, we recommend using the Dataspecer tool. This tool is fully dockerized for easy deployment. To work with it, it must be implemented on your own local or virtual server. The CCMM export can be uploaded into the tool as a baseline, after which additional classes or attributes can be added—either from existing schemas or by creating custom attributes.
In addition, the National Repository Platform project is developing a methodology for creating metadata profiles, where this process will be described in detail.
