2 weeks ago I've ported this older a11y ticket to the new InvenioRDM a11y project, because it remains an issue.
Some additional detail:
While accordion separators in the upload form do now receive keyboard focus, they do not announce their state (expanded vs. collapsed).
At present, accordions are styled <div> s:
<div class="accordion ui inverted invenio-accordion-field ">
<div tabindex="0" class="active title">Files<i aria-hidden="true" class="angle right icon"></i></div>
<div class="content active">

Proper Use of ARIA Roles and Properties
role="button": Each accordion header that can be expanded or collapsed should have a role="button" to convey to assistive technologies that it is interactive.
aria-expanded: This attribute should be used on the accordion headers to indicate whether the associated panel is currently expanded (aria-expanded="true") or collapsed (aria-expanded="false"). This dynamically updates as users interact with the accordion.
aria-controls: The aria-controls attribute should be used on the accordion header to reference the id of the associated content panel. This tells assistive technologies which content is controlled by each button.
The accordion field used in the deposit form needs accessibility (role/aria-attributes, keyboard accessibility). https://github.com/inveniosoftware/react-invenio-forms/blob/master/src/lib/forms/AccordionField.js#L52

Note: can use the
onTitleClickfunction that comes with semantic UI to update the values. See https://react.semantic-ui.com/modules/accordion/
