Why the RSL Standard Matters for Content Licensing on the Modern Web
Generative AI systems now sit between publishers and their audiences. Articles, product data, and documentation are collected at scale, absorbed into training datasets, and later returned to users as direct answers—often without a visit to the original source. The value of that content does not disappear, but the control over how it is used often does.
At this point, the question is no longer whether AI systems will process your content, but under what terms they do so—and whether those terms are clear, visible, and consistent.
This is the role of the Really Simple Licensing (RSL) standard.
What Is the RSL Standard?
The Really Simple Licensing (RSL) standard, introduced in 2025, is an open, XML-based protocol that allows website owners to publish machine-readable licensing terms for automated agents, including AI crawlers.
Instead of relying on human-readable legal pages or access-only controls, RSL provides explicit usage permissions that software agents can detect, interpret, and respect automatically. These permissions apply to distinct AI activities such as training, indexing, and real-time response generation.
RSL extends the intent of robots.txt by describing how content may be used, not merely whether it may be accessed.
According to the official RSL registry, several hundred organisations are already publishing RSL licences, spanning publishers, community platforms, and technical documentation sites. Adoption continues to grow as AI providers formalise crawler behaviour around declared licensing terms.
For site owners, RSL turns implicit assumptions into clear, published instructions.
What RSL Is—and What It Is Not
What RSL does
- Declares permitted and restricted AI usage types
- Provides a public, auditable record of licensing intent
- Enables consistent signalling across AI crawlers
- Supports future commercial agreements without structural changes
What RSL does not do
- It does not remove content from existing AI training datasets
- It does not block bad-faith or non-compliant crawlers
- It does not guarantee payment on its own
RSL is a licensing signal, not a legal enforcement mechanism. Its value lies in clarity, consistency, and scale, especially when paired with contracts, monitoring, and regulation.
Why robots.txt and legal pages fall short
Existing tools were never designed for modern AI usage patterns.
- robots.txt controls crawler access, not downstream usage
- Legal terms pages are written for people, not machines
- API terms apply only where a direct integration exists
RSL fills this gap by expressing usage permissions in a structured format that automated systems can interpret without ambiguity.
Why Your Business Needs RSL Now
Revenue protection
When AI-generated responses replace visits to your site, the loss appears as fewer leads, subscriptions, or enquiries. RSL allows you to permit discovery while restricting substitution, or to publish terms that support later commercial use.
Legal clarity
As regulators increase scrutiny of unauthorised AI data use, organisations are expected to demonstrate clear licensing intent. Publishing an RSL licence creates a timestamped, public declaration of your position.
Operational consistency
Without a standard, permissions are handled crawler by crawler. RSL replaces this with one declaration that applies across the AI ecosystem.
AI-first discoverability
As AI systems become a primary interface to information, RSL helps ensure your content remains discoverable under declared conditions, rather than silently absorbed.
Removing the Complexity: The RSL Licence Generator
Creating an RSL licence manually requires:
- Correct XML structure
- Understanding the RSL schema
- Careful handling of URL patterns and permissions
For many teams, this overhead delays adoption.
The RSL Licence Generator at https://tools.my247apps.com/rsl/ converts policy decisions into compliant RSL XML through a guided interface. No specification manuals are required, and the output conforms to RSL 1.0.
Important Update: Multiple URL Patterns per Licence
Important: The RSL Licence Generator now supports multiple URL patterns within a single RSL XML file. Each URL pattern can carry its own licence rules and permissions.
This is a significant improvement, because different sections of a site often require different licences.
Examples include:
/blog/*— open for AI training and indexing/docs/*— allowed for AI input/grounding with attribution/premium/*— restricted from AI input and AI indexing/api/*— excluded entirely from AI use
Previously, this required awkward workarounds or multiple files. You can now express granular, section-specific licensing rules cleanly within a single, standard-compliant RSL document.
Key RSL Permission Types Explained
Before generating a licence, it helps to understand the permission categories:
AI Training Use of content for long-term model learning or fine-tuning.
AI Input / Grounding Use of content as live context when generating responses.
AI Indexing Inclusion of content in AI-operated retrieval or answer layers.
Search Indexing Traditional search engine indexing, unrelated to AI generation.
Each permission can be allowed or restricted per URL pattern.
Generating Your RSL Licence
Step 1: Define your content scopes
Add one or more Content URL Patterns, such as:
/— entire site/blog/*— editorial content/docs/api/*— technical documentation/premium/*— paid or restricted areas
Each pattern can now carry its own licence configuration, allowing precise control without fragmentation.
Step 2: Select AI usage permissions
For each URL pattern, choose which AI activities are permitted.
A common configuration:
- Allow AI training and AI indexing
- Restrict AI input/grounding on high-value pages
- Keep search indexing enabled to preserve organic visibility
The generator ensures permissions remain valid and correctly structured in the XML output.
Step 3: Configure payment terms
Select No payment required (Free) for open content.
The same structure supports future commercial terms should you later decide to charge for certain forms of AI use—without changing the underlying format.
Step 4: Identify the rights holder
Add:
- Copyright holder
- Contact email
This transforms the licence from an anonymous signal into a verifiable business declaration, increasing the likelihood of compliance by legitimate AI operators.
Deploying Your RSL Licence
Host the generated XML at a public URL, typically:
https://yourdomain.com/license.xml
Reference it in robots.txt:
User-agent: AI-Bot
License: https://yourdomain.com/license.xml
For broader compatibility, also add it to your HTML headers:
<link rel="licence" type="application/rsl+xml"
href="https://yourdomain.com/license.xml" />
Deployment checks
- The licence file must be publicly accessible
- Do not block it via robots.txt
- Validate the XML structure
- Ensure URL patterns match real site paths
Deployment usually takes minutes. The clarity it provides lasts far longer.
Further thoughts…
AI systems already read your content. Without explicit terms, they also decide how it is used.
Publishing an RSL licence replaces assumption with instruction—and the ability to define different rules for different parts of your site makes those instructions practical.
Generate your RSL licence at https://tools.my247apps.com/rsl/ The tool is free, requires no registration, and produces compliant XML immediately.
Feedback from real-world use continues to shape the generator. If a workflow feels unclear or restrictive, that input directly informs future updates.
Clear terms scale better than private negotiation. RSL provides the structure. The generator removes the friction.
