Parser

Parser is responsible for defining element structures based on output from Loader.

To give you an idea what a Parser does, this is a snippet of a sample JSON output:

{
    "text": "[Header] This is the Header of the Document",
    "structure": "header", // 👈 parser defines this as "header" (previous value from Loader is "uncategorized")
    "metadata": {
        "source": "pdf-example.pdf",
        "source_type": "pdf",
        ...
    }
}

You can compare with the output from Loader here.

Possible structure values:

1. PAGE

2. HEADER

3. TITLE

4. HEADING (HEADING 1 through HEADING 6 )

5. PARAGRAPH

6. FOOTER

7. FOOTNOTE

8. TABLE

9. IMAGE

10. AUDIO

11. VIDEO

12. UNCATEGORIZED
