If you want to provide a custom schema, it should be a JSON object with the following structure:

{
  "name": "Schema Description",
  "baseSelector": ".container-class",
  "fields": [
    {
      "name": "title",
      "type": "text",
      "selector": ".title-class"
    },
    {
      "name": "authors",
      "type": "list",
      "selector": ".author-link",
      "fields": [
        {
          "name": "author_name",
          "type": "text"
        }
      ]
    },
    {
      "name": "paper_url",
      "type": "attribute",
      "selector": "a.paper-link",
      "attribute": "href"
    }
  ]
}
