Maybe attaching the files was inconvenient.

Haskell code
```
import qualified Data.Text as T
import Text.Pandoc
import Text.Pandoc.Walk (query)

-- Extract YAML metadata from document
getMetaData :: Pandoc -> Meta
getMetaData (Pandoc meta _) = meta

-- Read an org document with a yaml metadata block and print it
printDocWithMetaData :: IO ()
printDocWithMetaData = do
  input <- readFile "root.org"
  let readerOpts = def {
    readerStandalone = True,
    readerExtensions = enableExtension Ext_yaml_metadata_block 
(getDefaultExtensions $ T.pack "org")
  }
  eitherDoc <- runIO $ readOrg readerOpts (T.pack input)
  doc <- handleError eitherDoc
  let metaData = getMetaData doc
  print metaData
```

Input file (root.org):
```
---
title: Hello, World!
author:
  - name: Your Name
    affiliation: Your Affiliation
---

* Introduction

Hello, World! This is a simple org-mode document with a YAML header.

* Conclusion

Thank you for reading!
```

Std out:
```Meta {unMeta = fromList []}```

The input file contains a yaml metadata block yet the pandoc reader isn't 
extracting it.
