Neo4j adding nodes and links

To add nodes and links, you should use Cypher queries (API still in development, sorry). Information about Cypher query language is available from neo4j manual:

http://neo4j.com/docs/stable/cypher-introduction.html

http://neo4j.com/docs/stable/cypher-getting-started.html

http://neo4j.com/docs/stable/cypher-query-lang.html

Information about all visible attributes is available in "Neo4j Node and Relationship properties". To execute query, run neo4j-shell utility. Example queries to make node and links.

$ cypher  
CREATE (n:NetAssistNode {name: 'naic.29632.as', ip_address: '205.162.49.41', icinga_name: 'netgraphz2 server'}) RETURN n;

$ cypher
MATCH (n:NetAssistNode), (m:NetAssistNode) WHERE n.name='sw-core-1g' AND m.name='netgraphz2 server' CREATE (n)-[r:LINKS_TO]->(m) RETURN r;

$ cypher
MATCH (n:NetAssistNode), (m:NetAssistNode) WHERE n.name='sw-core-1g' AND m.name='netgraphz2 server' CREATE (m)-[r:LINKS_TO]->(n) RETURN r;

This set of queries would create node with single attribute name (value 'netgraphz2 server') and link it to existing node with name 'sw-core-1g' (if such node exists).
