GraphQL API - is there any documentation on blob truncation?

Body

I want to programmatically access the contents of this file in an existing GitHub repository.

I'm testing this by executing the following query in the GitHub GraphQL API Explorer:

query {
  repository(name: "OBOFoundry.github.io", owner: "OBOFoundry") {
    object(expression: "master:registry/ontologies.jsonld") {
    	... on Blob {
        text
        isTruncated
        byteSize
      }
    }
  }
}

The isTruncated value is true, and the text doesn't contain the entire contents of the file at that location. Is this because the file is too large? I can't seem to find any documentation on blob truncation.

Is there an alternative that I should use if I want to programmatically access the entire content of a file in a repository?
