The openMINDS_core repository is part of the open Metadata Initiative for Neuroscience Data Structures (openMINDS). It contains schemas used to describe the general origin, location and content of neuroscience research products. The openMINDS_core schemas cover metadata for the basic integration of research products into the EBRAINS Knowledge Graph.
The major versions are developed and maintained in different version-branches. Each version can be accessed by checking out the corresponding version-branch. You are currently on version-branch v3. Note: the default branch is always the latest version-branch in use within the EBRAINS Knowledge Graph.
For application and technical details please go to the central openMINDS repository or the openMINDS Collab.
In the schemas directory, all openMINDS_core schemas (v3) are defined in the openMINDS syntax (*.schema.tpl.json). Details about the openMINDS syntax can be found here. For convenience, related openMINDS_core schemas are grouped into subdirectories. To ensure a central access point for all openMINDS schemas across all versions and metadata models, each change in the schemas will lead to a new build of the central openMINDS repository.
In the instances directory, it is possible to store controlled instances (as JSONLDs) for selected openMINDS_core schemas (v3). The subdirectory of instances should resemble the schemas directory with the schema type as an additional subdirectory. The controlled instances are used within the EBRAINS Knowledge Graph to increase data integration.
In the tests directory you can find JSON-LDs designed to test the validation behaviour of each schema. The subdirectory of tests should resemble the schemas directory with the schema type as an additional subdirectory. Each JSON-LD follows the naming convention {schema_name}-{custom_test_name}.jsonld. For test cases supposed to fail the validation, the suffix -nok should be attached ({schema_name}-{custom_test_name}-nok.jsonld). The tests are validated every time a change is introduced and therefore are ensuring the correct behavior of the schemas.
In examples you will find several possible serializations of the openMINDS_core metadata model. The scope of each example is described in it's README. The correspondingly generated JSON-LDs may be further structured (e.g., grouped according to the schema they are validated against).
