The following changes have been made for ArcGIS Knowledge at this release:
If you configured an ArcGIS Enterprise 11.1 Knowledge Server appropriately, you can optionally create a knowledge graph that accesses existing data in a Neo4j database as a NoSQL data store. The data will be read-only.
Caution:
To support this capability, significant changes were made in ArcGIS Pro and ArcGIS Enterprise that introduce compatibility issues for existing projects using knowledge graph data.
New capabilities are also available in ArcGIS Pro to analyze and query knowledge graphs in an investigation, a link chart, a map, and in the Search and Filter pane.
