# Sites with a broken RSL licence

A site-wide report: one row per host, over the rsl rows the crawl emitted.

## What this report returns

RSL (Really Simple Licensing) puts a License line in robots.txt that points at an XML licence, telling AI crawlers on what terms they may use the site's content.

A row appears here when any of these is wrong, worst first:

-   **License Not Absolute**A License line in robots.txt gives a relative address such as `/license.xml`, but it must be a full URL, so crawlers can't reliably find the licence.**Fix** Write License: `https://example.com/license.xml`.
-   **License Unreachable**The licence a License line points at answered that it isn't there (for example 404), so crawlers find no licence and treat the content as unlicensed.**Fix** Publish the licence at that address, or point the line at where it is.
-   **Malformed XML**The licence file isn't well-formed XML (an element that never closes), so a crawler can't read its terms.**Fix** Validate the file and close every element.
-   **Wrong Namespace**The licence's root isn't `<rsl>` with the RSL 1.0 namespace as its default namespace (an older draft namespace or a prefix instead), so crawlers that identify licences by namespace don't recognise it.**Fix** Start the file with `<rsl xmlns="https://rslstandard.org/rsl">`.
-   **Missing Content**The licence has no `<content>` element, so it licenses nothing.**Fix** Add `<content url="/">` with a `<license>` inside it.
-   **Content Missing URL**A `<content>` element has no url attribute, so a crawler can't tell which content the licence covers.**Fix** Add one, e.g. `<content url="/">` for the whole site.
-   **Content Missing License**A `<content>` element has no `<license>` inside it (terms on their own are not a licence), so the content it names stays unlicensed.**Fix** Add a `<license>` with what you permit, e.g. `<license><permits type="usage">`ai-train`</permits></license>`.

Spec: RSL 1.0, sections 2.2, 3.2, 3.3 and 4.4.1. Sites with no License line don't appear here, because absence is not a failure.

## The columns it shows

Every defect this technology can carry is a column in the grid, worst first, so nothing is hidden behind a filter you have to know to apply.
