Real Simple Licensing (RSL) and the Future of AI Data Licensing

by ChatGPT-4o

In September 2025, a pivotal development in the evolving battle over AI training data emerged: the launch of the Real Simple Licensing (RSL) protocol. Spearheaded by Eckart Walther (co-creator of RSS) and backed by publishers like Reddit, Yahoo, O'Reilly Media, and Ziff Davis, RSL introduces a machine-readable standard for content licensing at web scale. Positioned as a successor to RSS — but with legal teeth — RSL marks a significant inflection point in the relationship between content creators and AI companies. This essay analyzes the mechanics and significance of RSL, assesses its suitability across content types and licensing models, explores its limitations, and offers a view on whether it signals a new era for AI-era content licensing.

I. What is Real Simple Licensing?

RSL is a dual-faceted protocol — technical and legal — that allows web publishers to express licensing preferences in a standardized, machine-readable way. Much like RSS allowed syndication of content for free, RSL provides the syntax and infrastructure for setting licensing terms on how AI crawlers may ingest and reuse content. This includes:

• Machine-readable licensing directives embedded in robots.txt or through Schema.org metadata

• Variable licensing terms, including free use, attribution requirements, pay-per-crawl, or pay-per-inference

• Encrypted access to proprietary or paywalled content

• Standardized public catalogs of licensable content

• A central rights management body (RSL Collective) akin to ASCAP or BMI for music licensing

Together, these components aim to transform the open-web status quo — where AI scrapers can exploit content without consent — into an economy of negotiated data rights.

II. Suitable Use Cases, Content Types, and Licensing Models

1. Ideal Use Cases

• Small and Medium-Sized Publishers: RSL provides a collective bargaining framework, enabling smaller players (e.g., bloggers, niche sites, news startups) to benefit from licensing schemes they couldn't negotiate alone.

• Web-First Media Outlets: Sites heavily reliant on content syndication or SEO, like CNET, People.com, or Medium, can monetize what has long been commodified in the AI ecosystem.

• Professional Knowledge Repositories: Publishers of programming guides, legal content, FAQs, or how-to content — often scraped for training AI — gain a structured mechanism to license that usage.

• Enterprise Training Data Providers: Companies offering curated datasets for AI, such as O’Reilly Media or WebMD, can now use RSL to secure licensing for both public web content and paywalled resources.

2. Compatible Licensing Models

• Collective Licensing: Through the RSL Collective, publishers can pool rights and benefit from economies of scale, enabling standardized deals.

• Custom or Premium Licenses: High-value publishers can still negotiate one-on-one deals (as Reddit did with Google) while remaining in the system.

• Creative Commons Alignment: RSL supports licensing that builds on or complements open licenses — allowing flexibility for academic or nonprofit domains.

III. Limitations and Unsuitable Scenarios

While promising, RSL is not a panacea. Several scenarios expose its current fragility or unsuitability:

1. Enforcement and Compliance

AI developers — especially smaller labs, open-source communities, or international actors — may simply ignore RSL. It lacks legal binding power unless combined with active monitoring, watermarking, or litigation. Web scrapers have historically ignored robots.txt directives, and RSL is vulnerable to the same risk.

2. Offline or Legacy Training

RSL only governs content accessed going forward. AI models already trained on historical web data (e.g., Common Crawl, Reddit archives) won’t retroactively owe royalties unless lawsuits compel compensation. For publishers looking to assert retroactive claims, RSL is structurally irrelevant.

3. Ambiguous Attribution and Traceability

Unlike music, where performance tracking is feasible, web content lacks clear signals to prove usage. If a model was trained on millions of documents, how does one trace a specific inference to a specific paragraph? Pay-per-inference models may face technical and legal hurdles unless LLMs become auditable by design.

4. Non-Textual Media

While RSL can embed licensing for text, metadata, and even video, it is less mature for scientific data, datasets in proprietary formats, software code, or machine-to-machine APIs. Publishers like academic journals or data repositories may need extensions to RSL to make it viable.

5. Market Disinterest from Frontier Labs

If leading AI companies — OpenAI, Google DeepMind, Meta — opt out or create rival systems, RSL risks becoming a protocol without a market. Enthusiastic adoption from publishers must be matched with uptake from model developers for RSL to survive.

IV. A New Era of AI-Era Licensing?

Despite limitations, RSL represents a bold attempt to rewrite the rules of engagement between publishers and AI labs. Several factors underscore its potential to usher in a new era:

• Technological Precedent: Like RSS and robots.txt before it, RSL aligns with web-native governance — contracts embedded in protocols.

• Economic Realignment: As web advertising collapses, publishers must extract value from data. RSL could redirect some of the AI boom's revenue back to original creators.

• Legal Pressure: With over 40 copyright cases pending (as cited in the TechCrunch piece), courts may begin to demand or endorse frameworks like RSL as viable alternatives to indiscriminate scraping.

• Public Sentiment and Fairness: RSL aligns with growing concerns about AI extractivism — the one-sided harvesting of human knowledge for private gain. It restores agency.

Yet, its success hinges on critical mass: enough publishers adopting RSL to make noncompliance reputationally risky or legally untenable, and enough AI firms willing to license rather than litigate.

Conclusion and Recommendations

For Citizens: Support publishers and platforms that demand ethical licensing. Push for transparency in how AI systems use your data — including blog posts, tweets, or online comments.

For Businesses:

• Publishers should adopt RSL, join the Collective, and consider watermarking, monitoring, and synthetic web traps to enforce compliance.

• AI developers should proactively engage with RSL or risk legal exposure, regulatory scrutiny, and consumer backlash.

• Startups can use RSL to differentiate by building AI on licensed, high-quality content — potentially yielding safer, more reliable models.

For Regulators:

• Mandate disclosure of training data provenance in LLMs.

• Recognize RSL or similar frameworks as part of AI auditing and risk management.

• Fund or support standardization and enforcement tools around digital licensing and watermarking.

RSL is not a silver bullet, but it is a compelling protocol-era solution to an extractive AI economy. If adopted and iterated upon wisely, it may become the HTML of ethical AI — quietly shaping the infrastructure of a more accountable internet.
