Dear Benoit,
this does sound like what I have done for my blog: I write all blog posts as org files in a single directory called "posts" and publish them through org-publish. In each file, I define tags via the =FILETAGS= keyword. Upon publishing, I set =:sitemap-format-entry= in =org-publish-project-alist= to a custom function which creates new org files corresponding to the tags being used in the posts. These org files are then published as well, giving me a sitemap with all posts and a sitemap for each individual tag (with short teaser text). This is not exactly what you asked for and maybe not as straightforward as what you envisioned, but I think that you could customize this approach to fit your use case. The code for my blog is available here: https://gitlab.com/hperrey/hoowl_blog (Please note that I copied it together from various sources back when without always understanding every detail and I am afraid that it shows.) The resulting html you can find here: https://www.hoowl.se Let me know should you have questions concerning the code!
