Meta Graph

Returns a virtual graph that represents the labels and relationship-types available in your database and how they are connected.

Table 1. Procedures
Qualified Name	Type	Release
apoc.meta.graphSample `apoc.meta.graphSample()` - examines the database statistics to build the meta graph, very fast, might report extra relationships	`Procedure`	`APOC Core`
apoc.meta.graph `apoc.meta.graph` - examines the full graph to create the meta-graph	`Procedure`	`APOC Core`
apoc.meta.graph.of `apoc.meta.graph.of({graph}, {config}) ` - examines a subset of the graph to provide a graph meta information	`Procedure`	`APOC Core`
apoc.meta.subGraph `apoc.meta.subGraph({labels:[labels],rels:[rel-types], excludes:[labels,rel-types]})` - examines a sample sub graph to create the meta-graph	`Procedure`	`APOC Core`
apoc.meta.data `apoc.meta.data({config}) ` - examines a subset of the graph to provide a tabular meta information	`Procedure`	`APOC Core`
apoc.meta.schema `apoc.meta.schema({config}) ` - examines a subset of the graph to provide a map-like meta information	`Procedure`	`APOC Core`
apoc.meta.stats `apoc.meta.stats yield labelCount, relTypeCount, propertyKeyCount, nodeCount, relCount, labels, relTypes, stats \| returns the information stored in the transactional database statistics`	`Procedure`	`APOC Core`
apoc.meta.nodeTypeProperties `apoc.meta.nodeTypeProperties()`	`Procedure`	`APOC Core`
apoc.meta.relTypeProperties `apoc.meta.relTypeProperties()`	`Procedure`	`APOC Core`

Table 2. Functions
Qualified Name	Type	Release
apoc.meta.cypher.type `apoc.meta.cypher.type(value)` - type name of a value (INTEGER,FLOAT,STRING,BOOLEAN,RELATIONSHIP,NODE,PATH,NULL,MAP,LIST OF <TYPE>,POINT,DATE,DATE_TIME,LOCAL_TIME,LOCAL_DATE_TIME,TIME,DURATION)	`Function`	`APOC Core`
apoc.meta.cypher.isType `apoc.meta.cypher.isType(value,type)` - returns a row if type name matches none if not (INTEGER,FLOAT,STRING,BOOLEAN,RELATIONSHIP,NODE,PATH,NULL,MAP,LIST OF <TYPE>,POINT,DATE,DATE_TIME,LOCAL_TIME,LOCAL_DATE_TIME,TIME,DURATION)	`Function`	`APOC Core`
apoc.meta.cypher.types `apoc.meta.cypher.types(node-relationship-map) ` - returns a map of keys to types	`Function`	`APOC Core`

In the case of LIST you may have many results, depending on the content. In the event that all contents are of the same type, will you have the LIST OF <TYPE>, otherwise if the type is different, will you get LIST OF ANY

If no type was found, the function return name of the class.

Table 3. Functions Deprecated
`apoc.meta.type(value)`	type name of a value (`INTEGER,FLOAT,STRING,BOOLEAN,RELATIONSHIP,NODE,PATH,NULL,MAP,LIST`)
`apoc.meta.isType(value,type)`	returns a row if type name matches none if not
`apoc.meta.types(node or relationship or map)`	returns a a map of property-keys to their names

If no type was found, the function return name of the class.

isType example

MATCH (n:Person)
RETURN apoc.meta.isType(n.age,"INTEGER") as ageType
