How to define meta in Haystack JsonConverter API

[allenwsh82]

Hello Guys,

Any idea how to define 'meta' for this API function?

def convert(file_path: Path,
meta: Optional[Dict[str, Any]] = None,
remove_numeric_tables: Optional[bool] = None,
valid_languages: Optional[List[str]] = None,
encoding: Optional[str] = "UTF-8",
id_hash_keys: Optional[List[str]] = None) -> List[Document]

Take for example of this json file attached.
meta_Magazine_Subscriptions.json

meta_Magazine_Subscriptions.json.gz

Hello...

I would try something like this:

from haystack.nodes import JsonConverter

converter = JsonConverter()
docs = converter.convert("data_file.json", meta=YOUR-META-DICT)

If your metadata is stored in a JSON file, you first need to convert it into a dict:

import json

with open("metadata.json") as f_in:
    metadata_dict = json.load(f_in)
