Accessibility/semantics question.

I've got a UI for building something with an option to preview the built thing in a drawer. Should the heading 'Preview' in the drawer be a <h1> or <h2>?

I can't decide if the drawer context is equivalent to a new document or a subsection of the current document.

Any views?

We are happy to welcome our new colleague Rafael Petronilo in our FIZ KDAI research team! Rafael originally comes from Portugal and is an expert in deep learning and knowledge graphs and we are very much looking forward to collaborate with him. He will be supporting our BMF project "Themenportal Wiedergutmachung nationalsozialistischen Unrechts"

Rafael standing in front of our grass world map in the FIZ Karlsruhe World Café. 🗨️Here's what Rafael himself says about his new job:
!I am excited to join FIZ as a PhD student and for the opportunity to work with this team. I have been fascinated by the concept of AI from a very young age. While growing up, it was exciting to see the technology evolve and how the line between science fiction and reality started blurring in the field. I aspire to be able to contribute to the further development of AI technologies. At the university, I did a bachelor's and master's degree in Computer Science and Engineering, focusing on multiple different AI topics, among which deep learning, natural language processing, neurosymbolic AI, explainable AI, knowledge representation, and automated reasoning. Now I wish to continue working towards pursuing an AI-focused research career. I think in the ISE department at FIZ I will have the opportunity to work with and learn from incredible people, facing new interesting challenges and finding innovative ways to tackle them."

25 years ago, Jim Hendler and his colleagues web inventor @timbl and @ora, an early expert on #AIagents, set out their #semanticWeb vision in an article for Scientific American magazine.

Semantic web implementations have since blossomed, deployed into every large enterprise on the planet and adding meaning to the web by appearing in the majority of pages on the internet.

A very edifying conversation. Hope you enjoy it, too.

Maximally Semantic Structure for a Blog Post

https://shkspr.mobi/blog/2026/01/maximally-semantic-structure-for-a-blog-post/

Yes, I know the cliché that bloggers are always blogging about blogging!

I like semantics. It tickles that part of my delicious meaty brain that longs for structure. Semantics are good for computers and humans. Computers can easily understand the structure of the data, humans can use tools like screen-readers to extract the data they're interested in.

In HTML, there are three main ways to impose semantics - elements, attributes, and hierarchical microdata.

Elements are easy to understand. Rather than using a generic element like <div> you can use something like <nav> to show an element's contents are for navigation. Or <address> to show that the contents are an address. Or <article><section> to show that the section is part of a parent article.

Attributes are also common. You can use relational attributes to show how a link relates to the page it is on. For example <a rel=author href=https://example.com> shows that the link is to the author of the current page. Or, to see that a link goes to the previous page in a series <a rel=prev href=/page5>.

Finally, we enter the complex and frightening world of microdata.

Using the Schema.org vocabulary it's possible to add semantic metadata within an HTML element. For example, <body itemtype=https://schema.org/Blog itemscope> says that the body of this page is a Blog. Or, to say how many words a piece has, <span itemprop=wordCount content=1100>1,100 words</span>.

There are many properties you can use. Here's the outline structure of a single blog post with a code sample, a footnote, and a comment. You can check its structured data and verify that it is conformant HTML.

Feel free to reuse.

<!doctype html>
<html lang=en-gb>
<head><title>My Blog</title></head>
<body itemtype=https://schema.org/Blog itemscope>

    <header itemprop=headline>
        <a rel=home href=https://example.com>My Blog</a>

This blog post is entitled "maximally" but, of course, there is lots more that you can add if you really want to.

Remember, none of this is necessary. Computers and humans are pretty good at extracting meaning from unstructured text. But making things easier for others is always time well spent.
