Deepin from London, interested in Graph application on knowledge management (Python)

Through Data Science I have discovered Graph Database and then much more from Neo4j (Thank you). With decade long engineering, knowledge management background , to me Graph database sounds just the right thing to look for. It can be foundation of next generation of knowledge management linked with data science. Through this community I hope I will find people and organisations in this field, current developments in this field etc. How utilisation of cypher/neo4j can be learnt, compatible with Python.
