Nexus offers an expressive knowledge representation language as well as tools to build high quality data models and to organise data in a knowledge graph where assets are related together. Each asset can be richly described using relevant controlled vocabularies.
Each entity can be modeled using schemas, giving you the opportunity to define its type, properties and constraints.
The platform can deal with any data and support the modeling of any domain of application.
Describe entities using existing vocabularies (e.g. schema.org) or develop your own and share it with your organisation. Import and manage domain specific ontologies to consistently describe your entities.
Define constraints on your entities using W3C SHACL to ensure that metadata is and remain of high quality.
The use of non proprietary technology facilitate sharing of modeling efforts. This enable the building of communities.
Securely ingest, organise and evolve your own data in a knowledge graph to start enabling all your data driven activities.
Metadata can be ingested without the need to define a very expressive and sophisticated data models.
Evolving your data to leverage these capabilities will make it more discoverable and rich, which in turn multiplies the value of your digital assets.
Data is not static, it evolves with your needs. Nexus enables you to plan and execute this evolution through data migration.
The constraints defined in your data model will be enforce upon data ingestion and ensure data compliance.
Upload and manage your raw data. Search and access them through high quality metadata.
Control which users and groups can operate on the assets.
All platform functionalities are available through REST APIs to facilitate automation and integration with third party software.
A python client facilitates integration with existing applications.
Data management of all the data which your organisation has to ensure is of high data quality throughout the complete lifecycle of the data. The resulting data in Findable, Accessible, Interoperable, Reusable.
Identify and capture all entities you want to capture and track to enable data driven activities.
Organisation wide sharing of controlled vocabularies as a powerful tool to provide a standardised and unified view of your assets.
Define a set of rules to enforce high quality metadata. These will be asserted during validation
Data evolve over time with the organisation’s use cases. Data lifecycle can be implemented through migrations.
Nexus allows to build customised views of assets specific to various user roles.
Use platform security to define who a access specific data.
Describe how your data was generated. Enable platform users to assess quality, build trust.
Navigate your knowledge graph to power your data driven activities.
Search across all your assets, using properties of your entities as well as their relations in your knowledge graph.
Get suggestions based on assets that match a given set of filters.
Download digital assets to fuel your data driven activities.
Data is exposed using international open standards to ensure maximum interoperability.
Leverage controlled vocabularies to expand user queries with synonyms, related terms.
Use our smart clients to visually navigate the knowledge graph and your data.
Explore your data using dynamically generated filtering tools determined by facets you can control
The Blue Brain Nexus is a provenance based, semantic enabled data management platform enabling the definition of an arbitrary domain of applications for which there is a need to create and manage entities as well as their relations (e.g. provenance).
For example, the domain of application managed by the Nexus platform deployed at Blue Brain is to digitally reconstruct and simulate the brain.
It is to be noted that many other scientific fields (Astronomy, Agriculture, Bioinformatics, Pharmaceutical industry, ...) are in need of such a technology. Consequently, Blue Brain Nexus core technology is being developed to be agnostic of the domain it might be applied to.
We'll guide you in adopting the platform for your domain.
