An identifier for a schema, allowing other schemas to reference it.
You may optionally specify an identity when defining an object schema. This signals that this schema represents an important named entity in the context of your pack. Schemas with identities may be referenced by other schemas, in which case Coda will render such values as @-references in the doc, allowing you to create relationships between entities.
Every sync table's top-level schema is required to have an identity. However, an identity will be created on your behalf using the identityName that you provide in the sync table definition, so you needn't explicitly create on unless desired.
The dynamic URL, if this is a schema for a dynamic sync table. When returning a schema from the getSchema formula of a dynamic sync table, you must include the dynamic URL of that table, so that rows in this table may be distinguished from rows in another dynamic instance of the same table.
When creating a reference to a dynamic sync table, you must include the dynamic URL of the table you wish to reference, again to distinguish which table instance you are trying to reference.
The name of this entity. This is an arbitrary name but should be unique within your pack. For example, if you are defining a schema that represents a user object, "User" would be a good identity name.
The ID of another pack, if you are trying to reference a value from different pack.
