I would like to add the ORCID to the metadata of documents I write. Is this possible with PDF? Is there a standard way to include it in TeX?
The nicest way would be if there way a standard TeX command so that the compiled PDF would automatically have this information. But if it is possible to add this after the PDF was compiled, it would be nice, too.
The simplest way to add the ORCID to the TeX code is adding a comment
% ORCID of the author: http://orcid.org/0000-0002-6517-1690
But how do other people add their ORCID to papers? Is there a recommendation how to do it, so that scripts / search engines can use the information?
