Metadata models & schemas

Version 24.1 by oschmid on 2021/02/23 16:31

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 and links to available metadata instances for selected schemas.

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

openMINDS core

The openMINDS core metadata model contains schemas that can be used to describe the general origin, resource location, and content of research products in the field of neuroscience. Currently ( Feb 2021) this metadata model comprises 37 usable schemas, grouped into five classes:

In case of EBRAINS, metadata representations (instances) of the schemas marked with an asterisk are centrally defined and maintained on a separate GitHub to guarantee more consistency across the database instances of the Knowledge Graph (cf. section openMINDS instances).

openMINDS SANDS

The openMINDS SANDS (Spatial Anchoring for Neuroscience Data Structures) metadata model contains schemas that can be used to capture the anatomical location of neuroscience data as well as to identify and highlight commonly used reference brain atlases and coordinate spaces. Currently (Feb 2021) this metadata model comprises 12 metadata schemas:

openMINDS controlledTerms - schemas

The openMINDS controlledTerms metadata model contains schemas that ensure consistent registration of well-defined terms, including linkages to existing ontological terms where applicable. Currently (Feb 2021) this metadata model comprises 38 nearly identical schemas:

Except for TermSuggestion (marked with an asterisk), the openMINDS controlledTerms metadata schemas differ only in their type which defines the name of the terminology the correspondingly controlled terms are registered to (cf. openMINDS controlledTerms - terminologies).

Compared to these schemas, the TermSuggestion has one additional property ("terminology") where users can state to which terminology the new suggested (not yet controlled) term belongs to. Within the EBRAINS Knowledge Graph, the metadata representations for TermSuggestion will be regularly reviewed by the openMINDS development team in order to integrate these community driven suggestions into the controlledTerms terminologies and corresponding ontology (where applicable).

openMINDS controlledTerms - terminologies

The openMINDS instances repository holds a collection of metadata representations (instances) of selected schemas which content should be more controlled to ensure their consistent definition and usage for the entire EBRAINS Knowledge Graph. Currently the repository holds collections for the following schemas:
