It would be nice to include the rating in <content> and <summary>, and also organize the tags in <content> into groups.
Instead of:
<content type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml"> <a href="https://danbooru.donmai.us/posts/9689416"> <img src="https://cdn.donmai.us/360x360/40/42/40427a0474465589ac8b948041bcef9d.jpg" /> </a> <p>1girl blue_archive blue_eyes blush braid commentary halo hat long_hair maki_(blue_archive) maki_(camp)_(blue_archive) pixel_art red_hair solo tinia_etru twin_braids</p> </div> </content>
Do it like this:
<content type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml"> <a href="https://danbooru.donmai.us/posts/9689416"> <img src="https://cdn.donmai.us/360x360/40/42/40427a0474465589ac8b948041bcef9d.jpg" /> </a> <p>tinia_etru</p> <p>blue_archive</p> <p>maki_(blue_archive) maki_(camp)_(blue_archive)</p> <p>commentary</p> <p>1girl blue_eyes blush braid halo hat long_hair pixel_art red_hair solo twin_braids</p> <p>rating:general</p> </div> </content>
