It looks like your site is hosted on Tumblr.com Silo without a custom domain name. In order to really own your content you need to own your URLs, but don’t worry — Tumblr has an article demonstrating how to give your web presence your own domain.
Once you’ve got your own domain, check out the IndieWeb Tumblr wiki page for tips on adding indieweb functionality to your site, or exporting your data elsewhere.
Your h-entries should have, at minimum, the following properties:
e-content — the main content of the postp-name — if your post is an article with a name, use this classname.dt-published — the datetime the post was published at, in ISO8601 format, with a timezoneu-url — the canonical URL of the post, especially important on pages listing multiple postsIt’s a common convention for the published datetime to be a link to the post itself, but they can be separate if you want.
There should also be some way to discover the author of the post — either link to your homepage (which should have your h-card on it) from anywhere within the body of the page with rel=author, or optionally embed a p-author h-card in the h-entry.
The web is an expressive medium, and as such there are many other properties which you can add to your posts. Check out the h-entry documentation for a full list.
