A bit of context ↩
Alright that intro might make you think I hate AI or something. So, let's get that out of the way because RSL can also help you train AI models if that's your thing too. It's a neutral protocol and one which you can use however you like.
In my case, I'm interested in humans reading my website, learning from it, and maybe dropping a line to me on twitter or twitch to tell me that they liked a post. If an AI bot shows up in my twitch chat, it gets a ban the moment it tries to solicit me and asks me if I have a discord. 1 Similarally, I like paying 5 bucks a month for neocities to host this blog, I don't want bots that never respect guidelines using the fruit of my brainworms, and working in the area of software I work in, I know that folks like OpenAI have some of the worst netizen behavior I've ever seen 2. We're talking stupid nonsense like "I have finished my request for page X of the RSS feed, I shall now request the same page to see if it changed" 3 times a second. 3
Ahem. This post isn't about that. This is about an emerging standard that a number of large media companies are throwing their weight behind and that you should consider adopting if you're a blogger who cares about licensing and that sort of thing. If you don't, that's fine. But if the thought of a large company taking your blog and using it as training data bothers you, you might want to keep reading.
So how do you add RSL to your site? ↩
It's really not hard. There's both a specification here on their website and examples there too. You basically have two options that aren't exclusive of each other:
- Add a License XML file to your site, update robots.txt to reference it
- Add RSL metadata to your RSS feed for your website
I've already done both for my website, so you can look at my robots.txt file 4 to spot the reference to my license.xml file, as well as take a peak at the RSS feed if you want to see what it looks like individually. You might be asking yourself: can I just do one?
Yes. A license XML file and an update to robots txt will probably do the trick. I don't have an RSS feed for my entire site, but I like being explicit about things just in case a crawler finds one and not the other. Not every crawler actually reads or respects robots.txt after all. The nice thing, is that legally speaking, having the license file and wild cards that apply to your whole site mean that if you really wanted to go lawyer up and fight with someone, according to the RSL standards, you can! Anyway. Here's mine:
<rsl xmlns="https://rslstandard.org/rsl">
<content url="/blag">
<license>
<prohibits type="usage">ai-all</prohibits>
<permits type="usage">search view copy share</permits>
<payment type="attribution">
<standard>https://opensource.org/licenses/MIT</standard>
</payment>
</license>
</content>
<!-- Catch-all for everything else -->
<content url="/">
<license>
<prohibits type="usage">ai-all</prohibits>
<permits type="usage">search view copy share listen</permits>
<payment type="attribution">
<standard>https://creativecommons.org/licenses/by/4.0/</standard>
</payment>
</license>
</content>
</rsl>
Okay so what does all that mean? Well the url property specifies
what the license we're defining applies to. This is a scope or a specific set
of pages. For example, if you wanted an AI to train on your /poison
directory but not on your /posts directories, you could setup a
separate section for that with a url="/poison/" that had some usage
settings like <permits type="usage">ai-all</permits> for
just that content section, and a <prohibits type="usage">ai-all</permits>
for the other. See how useful and simple that is?
All the core terms are defined within the namespace with full definitions on the RSL website if you're curious. In the case of my license, you can see that I prohibit all current and future AI related usages for my site's content, but I allow search for robots, which is then further refined by the robots.txt file that also points to the license file:
# Ultimate AI Block List v1.6 20250718 # https://perishablepress.com/ultimate-ai-block-list/ License: https://peetseater.space/license.xml # Allow all other bots full access User-agent: * Disallow: # Block AI bots from all access User-agent: .ai .... User-agent: Zimm Disallow: /
This may seem like they're at odds with each other, allowing bots in one place but not the other
but when it comes to the mixture of these things, the more prohibitive of the two always applies
when we're talking about broadstrokes paths like /. If I specify something more specific like
/blag/ then that will come into play as dictated by section 4.9 of the spec:
When multiple licenses are discoverable for the same asset (for example, both a site-wide license in robots.txt and a page-specific embedded license):
The most specific license (e.g., page-level) takes precedence over broader site-level licenses.
If two licenses define conflicting terms, clients MUST honor the most restrictive combination of rights.
Publishers SHOULD ensure consistency across discovery channels to avoid ambiguity.
As you can see, they explicitly call out the case where both robots and license exists. And it says that publishers (you and me) should try to be consistent, but aren't required to. It's on the consumer to check that they're following the most prohibitive licensing terms available to them based on the combination of rights given through the files.
The neat thing, which doesn't really apply to my blog but could apply to yours if you intend to monetize content, is that the RSL has some RSL license servers already setup that enable the paying of royalties and the like to folks who use the RSL specific licenses. You can see the server attributes neccesary to use those on the RSL Collective website and I imagine a quick dive into the partners and publishers sections can teach you whatever you need to know about the fair pay initiative pushed by the media companies involved with this.
Getting back to the details though, the other important thing in the license xml file that any hobbyist should include is the license itself! By default, most developers probably want to use either MIT or the Creative Commons license. MIT is the one that github gives you when you set up your typical repo that basically functions as an "as is" type license and says that folks need to attribute the use of the content back to you. Good if your main goal is building street cred for that eventual job interview you might need. Creative Commons is similar, but different, one is used with code while the other is used with creative stuff like text, datasets, images, etc. In my case, I've mostly got code in the site, so that gets covered by MIT. The images that I use on the site are mostly from my own screenshot collection or support that blog, and so that gets covered by the CC. None of it is trainable though, just because I took a funny screenshot for my own fair use to enrich the blog posts with transformative amusement doesn't mean that an AI should train on that image.
If you want to be specific on certain posts, then you can add in RSL docs to your RSS feed. For example, if I wanted to post a trainable post for an AI, then I could provide a more specific license so that it applies to the one post and lifts the restrictions my general license has like so in my XML feed:

In this case, becuase the content url is page specific, it applies instead of the catch-all, and then the bot sucking down the content would need to go to the RSL collective's API systems and retrieve a token via the Open Licensing Protocol. Which would then pay me the big bucks every time someone got served information that came from the data the AI learned from me. 5
And yeah, that's basically it!
Final notes ↩
As I said, the RSL is an emerging standard. Some random Chinese bot that wants to steal all your data is going to steal all your data without any regard for this stuff. However, companies that operate in the US and get sued regulary have a pretty vested interest in opting in and obeying this stuff. Especially when you look at the list of companies supporting this initiative:
You'll probably spot some familiar company names in there, and quite a few you've never heard of that probably operate as parent companies of others you have. While it often feels hopeless when you see how AI companies steal entire sites worth of information, this is an actual legal framework that allows companies and potentially individuals to start clawing back their data. Though, in some cases, it may be too late to save the sites original purpose and a "if you can't beat em, join em" strategy is all they have left.
At least with RSL, when you join them, you can get some royalties or prohibit the "good bots" and if they ever acquire or link to your stuff in a way that shows that they obtained the data through other less rsl-abiding channels, you'll have a license file to point to that can be used to tell them to remove the offending content. Hope this helps or sparks some ideas for all my fellow blogosphere friends!
