<!-- Answer -->
To create HugeGraph graph schema metadata such as `VertexLabel` and
`EdgeLabel` using Gremlin syntax, you can use the following examples:
**Creating VertexLabel:**
```groovy
person = graph.schema().vertexLabel("person").properties("name", "age",
"city").primaryKeys("name").ifNotExist().create()
software = graph.schema().vertexLabel("software").properties("name", "lang",
"price").primaryKeys("name").ifNotExist().create()
```
**Creating EdgeLabel:**
```groovy
knows =
graph.schema().edgeLabel("knows").sourceLabel("person").targetLabel("person").properties("date").ifNotExist().create()
created =
graph.schema().edgeLabel("created").sourceLabel("person").targetLabel("software").properties("date",
"city").ifNotExist().create()
```
These examples demonstrate how to define vertex and edge labels with
associated properties and primary keys using Gremlin syntax in HugeGraph.
Additionally, you can create property keys before defining vertex and edge
labels:
**Creating PropertyKey:**
```groovy
graph.schema().propertyKey("name").asText().ifNotExist().create()
graph.schema().propertyKey("age").asInt().ifNotExist().create()
graph.schema().propertyKey("city").asText().ifNotExist().create()
graph.schema().propertyKey("lang").asText().ifNotExist().create()
graph.schema().propertyKey("date").asText().ifNotExist().create()
graph.schema().propertyKey("price").asInt().ifNotExist().create()
```
These property keys are then used in the vertex and edge label definitions
