Term for #+ lines (filetag, date, ...) in an org file

Term for #+ lines (filetag, date, ...) in an org file

[c.buhtz]

In orgroam I know about lines like this

#+filetag MYTGA
#+date 00000

between the PROPERTIES head and the body of the org file.

What is the term for lines like this and are there any rules or 
specifications about how they should(n't) look like?

See 7.1 Property Syntax
Those are buffer-wide properties.
