hello .. am trying to understand how to add custom metadata to a pdf document parsed with llamaparse and MarkdownElementNodeParser (i followed the demo) ... but not sure how to add custom metadata?
thanks.... this works... any thoughts on how to use the metadata extractors to accomplish this ... where i'm getting confused is that all examples suggest splitting the document into nodes while with Llamaparse it seems easier to use MarkdownElementNodeParser and i'm not sure how use it in a pipeline
