Establish a sustainable data searchcapability for the output of theinternational brain initiatives

The Google Knowledge Graph

The Google Knowledge GraphGoogle Dataset Searchhttps://developers.google.com/search/docs/data-types/dataset
Currently only supports whole datasets, not granular individual data entities.

Structured dataschema.org
The schemas are a set of 'types', each associated with a set of properties.
The types are arranged in a hierarchy.
The core vocabulary currently consists of 614 Types, 902 Properties, and114 Enumeration values.

Why do businesses implement structured data?

Structured data helps sites appear inGoogle’s Knowledge Graph
For sites that appear in highly competitive verticals,
getting the edge over your competition is critical, andone way to do this is by establishing your site presencewith Google and appearing in the Knowledge Graph.
To enable your business Knowledge Graph card, earlier
you would have needed to add the necessary Corporate
Contact markup on the homepage of your website.

Towards an International Brain Initiative Knowledge Graph…
Why should neuroscientists implement
structured data descriptions in theirwebsites?
What are the incentives in neuroscience that will make itso motivating to establish the presence of your data in an
International Brain Initiative Knowledge Graph?
To enable your neuroscience data Knowledge Graph card,earlier you would have needed to add the necessary
Brain Research Data markup on your website. Then thea data card could be automatically added to the IBI
Knowledge Graph.

First review all current brain initiative approaches
to structured metadata:• Human Brain Project - EBRAINS Knowledge Graph• Blue Brain Project - Neuroshapes• Japan Brain/MINDS Data Portal• Canadian Open Neuroscience Platform• INCF KnowledgeSpace• DANDI: Distributed Archives for Neurophysiology Data Integration• SPARC Data Structure

Example:• Launched in 2014, Brain/MINDS is Japan’s Brain Mapping
Project.

• The core institute for the project is RIKEN and it wassponsored by MEXT in 2014 and now AMED since 2015.

• The unique appeal of the Brain/MINDS project is its focus
on mapping the brain of a small new world monkey, thecommon marmoset (Callithrix jacchus).

Currently only supports whole datasets, not granular individual data entities.

Limitations of Google
Dataset Search:• No guarantee that your datasets will be indexed or searchable• No application programming interface to build other searchengines• No support for neuroscience specific metadata• Limited to entire datasets- not clear when it might support neuroscience record leveldata

INCF KnowledgeSpace - knowledge-space.org
A community-based encyclopedia/data discoverability portal for neuroscience that links
brain research concepts to the data, models, and literature that support them.
Features:Core concepts:● Provides a search engine for neuroscience
resources including data, computationalmodels and literature● Supports encyclopedia articles with links torelated resources● Provides an API to support FAIR data

Supported by:

●

Descriptions of neuroscience research concepts
Links to ontologies that define concepts
Links to PubMed entries associated with the concepts
Links to data/models related to the concepts

Proof of Concept IBI Data Search:KnowledgeSpace integrates IBI Data Sources:

Next steps:• Prepare an inventory of available data repositories in the brain initiatives, metadatastandards, and governance models for data access;• Establish a sustainable governance process for developing, approving, and revising astandard metadata model(s) for describing neuroscience datasets;• Develop tools, best practices, and guidelines for publishing datasets using thestandard metadata model;• Configure and operate a core infrastructure and portal for ingesting, indexing, andsearching dataset metadata;• Define and implement interoperability with existing data portals and infrastructures,and interoperability guidelines for new repositories;• Develop and disseminate tutorials, training materials, and educational activities fordataset publishing;• Develop and enact a global communications strategy to internal stakeholders, fundingorganizations, and neuroscience researcher communities regarding the activities andproducts of this project.
