What is better to indicate in the link of the abbreviated article details or bookmark?

Question

Search Engine Optimization

Hello dear friends!
Please tell me which attribute is better to specify in the link of the abbreviated article rel="details" or rel="bookmark" my site will export articles to the blog. And on this blog, the article will look like an announcement with a link to the full article.
What attribute will be correct so that the search engine understands that this is an announcement and that they need to switch to the full version?
Forgive me in advance for my ignorance, SEO is just stupid ...
Thanks in advance!
