orcidlink.sty and metadata

[dginev]

I had a conversation with @physikerwelt today where he suggested we could also add some rich metadata to the orcid identifiers emitted from LaTeXML.

Looking at how some orcid-enabled journals have achieved this, such as SIAM Journal on Computing, I see an RDFa pattern, for example:

<div id="contrib3" property="author" typeof="Person">
  <div class="heading">
    <span property="givenName">Hanlin</span> <span property="familyName">Ren</span>
    <a class="orcid-id" href="https://orcid.org/0000-0002-7632-7574" property="identifier" aria-label="ORCID identifier" target="_blank">https://orcid.org/0000-0002-7632-7574</a>
  </div>
  <!-- ... affiliation etc goes on... -->
</div>

They have made some interesting choices:

• using property="identifier" on the orcid link, combined with property="author" on the container div.
• marking up the name pieces of the author with property attributes
• target="_blank" convenience ensuring the link opens in a new tab

What Moritz and I discussed today is mostly that it would be helpful to already have the latexml-generated HTML contain structured data, RDFa in this case, allowing that the extraction of that metadata can be done using a standard workflow.

The orcid piece is in a way the easiest one - having the right property attributes on the person name, affiliation, etc, could be more difficult, given the variance of constructs we have in LaTeX class files.

Filing this as an issue, since we will inevitably forget about it otherwise.

This discussion is also in follow-up to landing PR #2595
