Why is this PDF metadata not valid?

I need help understanding how to make this document compliant. Any other advice would be wonderful.

I have been digging through the various examples, tutorials, and official documents; and I think I am close to the solution.

The "hello world" text appears in the MediaBox, but metadata is inaccessible.

The rules seem clear, but things like Title do not appear for pdfinfo or File>Properties.

Start with 1 for document information and put the keys in a dictionary object, your sample is missing the << and >>:

% Metadata (referenced by trailer /Info)

1 0 obj
<<

  /Subject      (test PDF)

  /Keywords     (PDF test)
  /CreationDate (D:2018021300000-05'00')
>>
endobj
