Metadata models and schemas

Last modified by lzehl on 2021/07/02 17:06

The openMINDS metadata models all consist of modular connectable metadata schemas. Each schema can be referenced by it's type and defines properties (including their expected value) for a set of related metadata.

A short overview for each openMINDS metadata model can be found below, including links to full HTML descriptions for all schemas across all versions. Note that for some schemas, openMINDS provides also a library of controlled instances. The available controlled instances are listed in the HTML view for the respective schema.

Note that all metadata models are licensed under the MIT license.

openMINDS core

The openMINDS core metadata model contains schemas that you can use to describe the general origin, resource location, and content of your research products in the field of neuroscience. Currently this metadata model comprises the following schemas (default: latest stable version):

Select a version and click on a schema to discover its full HTML description.

For the schemas ContentType, License, and Protocol, openMINDS provides a library of controlled instances that were defined and reviewed by corresponding experts of the openMINDS development team (cf. also below). In particular within EBRAINS, the usage of these controlled instances increase the level of data integration inside the EBRAINS Knowledge Graph. Feel free to explore these instances (in the HTML view or on the GitHub) and make use them, inside or outside of EBRAINS.

For further details or to review schemas of an older version of this metadata model, please check out the openMINDS core GitHub repository.

openMINDS SANDS

The openMINDS SANDS (Spatial Anchoring for Neuroscience Data Structures) metadata model contains schemas that you can use to capture the anatomical location of your neuroscience data as well as to identify and highlight commonly used reference brain atlases and coordinate spaces. Currently this metadata model comprises the following schemas (default: latest stable version):

Select a version and click on a schema to discover its full HTML description.

openMINDS controlledTerms

The openMINDS controlledTerms metadata model contains schemas that ensure consistent registration of well-defined terms, including linkages to existing ontological terms where applicable. Currently this metadata model comprises the following schemas (default: latest stable version):

Select a version and click on a schema to discover its full HTML description.

Except for TermSuggestion, the openMINDS controlledTerms metadata schemas differ only in their schema type which defines the terminology to which the correspondingly created metadata representations (instances) belong to. 

For all controlled terms schemas (except TermSuggestion), openMINDS provides a library of controlled instances that were defined and reviewed by corresponding experts of the openMINDS development team (cf. also below). In particular within EBRAINS, the usage of these controlled instances increase the level of data integration inside the EBRAINS Knowledge Graph. Feel free to explore these instances (in the HTML view or on the GitHub) and make use them, inside or outside of EBRAINS.

The TermSuggestion schema was introduced to facilitate community-driven requests for new controlled terms and respective instances for the properties "studyOption" and "studyTarget" (which needs are particularly difficult to predict). Correspondingly suggested metadata instances will be frequently evaluated and integrated as proper controlled instances on the GitHub repository be the openMINDS development team.

For further details or to review schemas of an older version of this metadata model, please check out the openMINDS controlledTerms GitHub repository.

openMINDS computation

The openMINDS computation metadata model contains schemas that you can use to capture the provenance of simulations, data analysis and visualizations. Currently this metadata model comprises the following schemas (default: dev):

Select a version and click on a schema to discover its full HTML description.

For further details or to review schemas of an older version of this metadata model, please check out the openMINDS computation GitHub repository.

openMINDS instances

For selected schemas, openMINDS provides a library of controlled instances that were defined and reviewed by corresponding experts of the openMINDS development team (cf. above). These instances are stored on the GitHub repository of the metadata model the respective schema belongs to. In particular within EBRAINS, the usage of these controlled instances increase the level of data integration inside the EBRAINS Knowledge Graph. Feel free to explore these instances (in the HTML view or on the GitHub) and make use them, inside or outside of EBRAINS.

The libraries of these controlled instances will grow based on your feedback. If you miss an instance or terminology, feel free to make a corresponding request via our support email (openminds@ebrains.eu) or raise an issue on the respective GitHub repository. Within EBRAINS, new controlled terms and respective instances for the properties "studyOption" and "studyTarget" (which needs are particularly difficult to predict) can also be made by filling out a TermSuggestion (cf. above).

All your request are reviewed regularly by the openMINDS development team, in order to integrate all community-driven suggestions (where applicable). In addition, your suggestions will be evaluated as possible extensions for the SciGraph ontologies, powered by the FAIR Data Informatics (FDI) Lab - SciCrunch Infrastrucutre and the INCF Knowledge Space team.
