v1.0 (25.01.2019)

This is the first major release of Blue Brain Nexus after almost two years of development.

Also referred to as "Nexus V1", this initial release is our first big milestone in our quest to build a Knowledge Graph platform uniquely combining flexible graph database, powerful search engine and scalable data store to enable:

  • Easy unification and integration of fragmented and disparate data from heterogeneous domains to break data and metadata silos
  • Better data governance with the ability to specify and enforce organization’s best practices for data collection, storage and description through high quality metadata
  • Data lineage and provenance recording and description
  • FAIR (Findable, Accessible, Interoperable, Re-usable) data and metadata management
