Examining schema

How to examine schema.

1. A list of all schema can be retrieved with the following command:

   schema.describe()

   In Studio and Gremlin console, a list is retrieved, although the presentation is different. Here is a portion of a Studio result:

   

2. The schema for a particular element can be examined by appending describe() to a more specific schema:

   schema.edgeLabel('includedIn').describe()

   schema.edgeLabel("includedIn").multiple().properties("amount").create()
   schema.edgeLabel("includedIn").connection("recipe", "meal").connection("recipe", "book").connection("recipe", "ingredient").connection("ingredient", "recipe").connection("meal", "book").add()

3. Some groovy steps are useful in the Gremlin query to find specific schema descriptions. For instance, to inspect only the vertex labels and their indexes, use the split() and grep()steps:

   schema.describe().split('\n').grep(~/.*vertexLabel.*/)

   In Studio:
