Why Technical Writers Must Evolve from Structured to Semantic Content
Shifting from structured to semantic content can help us enhance AI-driven precision
I once thought structured content was the pinnacle of technical writing sophistication. Like labeling all your moving boxes and patting yourself on the back for being organized, I marveled at its clean tags and nested elements, smugly assured that everything was in its place. But just as you can’t solve life’s problems with a color-coded filing cabinet, I’ve come to realize that structured content, while essential, isn’t the whole story.
Welcome to the world of semantic structured content,
where you organize data to make it meaningful.

Structured Content: The Foundation
Structured content organizes information into a predictable framework using markup languages like Extensible Markup Language (XML) or its specialized cousin, the Darwin Information Typing Architecture (DITA). It locks in consistency, makes reuse a breeze, and lets you publish content across platforms and channels.
Structured content has been a lifesaver for tech writers, rescuing us from the Wild West of unstructured documents and giving us scalable workflows instead of headaches.
But here's the rub: structured content, while fantastic for organizing information, doesn't know what it's talking about. It's like following a recipe exactly but not understanding why baking soda makes the cookies rise. Sure, it's got the structure down, but where's the meaning? Enter semantic content.

Semantic Content: Adding Meaning to Structure
Semantic content, the sophisticated older sibling of structured content, is the key to unlocking a deeper understanding. It doesn't just organize information; it explains what the content means and how it connects to other information. Using technologies like RDF or vocabularies like schema.org, semantic content enriches structured content with context and relationships that machines—and humans—can understand, enlightening readers and enhancing their knowledge.
Think of it like this: structured content is a beautifully organized cookbook written in XML. Semantic content is the same cookbook, but with notes in the metadata that say, "This recipe pairs perfectly with that one," or "Use this ingredient as a substitute in case of dietary restrictions." It's all about adding meaning to the structure, making the content more intelligent and thus more informative.

Here’s another example: a structured content model might include a product name, description, and specifications in a table. Semantic content, however, would go further by explicitly defining relationships, such as "Product X is compatible with Product Y" or "Specification A is required for Feature B." This added layer of meaning allows AI systems to draw inferences, answer nuanced questions, and create contextually-relevant connections that structured content alone cannot.
Why You Need Semantic Structured Content Now
You might think, "This sounds great, but do I need semantic content right now?" The answer is an unequivocal yes. AI and machine learning systems are rapidly becoming central to how people access information, and they thrive on context. They need content that doesn't just say, "Here's some data," but also explains, "Here's why this matters and how it connects to everything else."
For example, structured content can give users detailed specs and instructions if you write product documentation. Semantic content, however, can tell them how features relate, which configurations are compatible, and what scenarios call for specific actions. It helps AI systems answer complex user questions, create personalized recommendations, and support richer user experiences.
Without semantic content, your content is just an instruction manual;
with it, it becomes an intelligent assistant.

So, How Do You Get Started?
Transitioning from structured to semantic content might sound daunting, but it's more manageable than you think. Start by understanding the basics of semantic technologies like Resource Description Framework (RDF), JSON-LD, and Web Ontology Language (OWL).
Look at your content and identify key relationships—what connects to what, and how? Adopt semantic standards like schema.org or industry-specific vocabularies to ensure your content is machine-readable and interoperable.
Most importantly, you should collaborate with your team to weave semantic thinking into your content strategy.

The Natural Evolution of Technical Documentation
The shift from structured to semantic content represents a natural evolution in technical communication. As the demand for smarter systems and personalized user experiences grows, so does the need for content that not only organizes information but also makes it understandable to machines. By embracing semantic content, technical writers can not only meet today’s challenges but also help shape the future of intelligent communication systems.
Now is the time to lead this transformation.
Thank you for making this distinction! I've been wrestling with the difference between the kind of structured content I've been talking about, and the kind that tech comms folks talk about. The key is the semantic part -- base content and its structure on meaning and intent, not format.
You're saying we should actually do our jobs and stop phoning it in?
When I took my current position, the so-called user guides were screen descriptions: "Check the 'no widget' box if you don't want a widget." This for a complex piece of software with many ways to work depending on how you set it up. It took a lot of time to clear all that up and I'm still adding process-oriented guides: how-to's, special setups for special functions, tips and hacks.
So now artificial intelligence can take credit for the fact that I bothered to do my job.
