+### Exec (TODO)
+
+We plan to support an `exec:` scheme,  whose content will be the resulting of running the given command,
+similar to e.g. [🐪 Camel's](https://camel.apache.org/components/4.8.x/exec-component.html) or (vaguely) Web Browsers'

+<!-- TODO ### Git `git:` ? -->
+
+## Parameters
+
+Enola considers certain generic query parameters in URLs it fetches.
+
+These work with most but not all schemes (e.g. `data:` does not permit query parameters).
+
+### Media Type
+
+Adding e.g. `?mediaType=application/json` [overrides the Media Type](../info/index.md#detect)
+which e.g. a server provided in e.g. a HTTP header,
+or that was determined from a file extension.
+
+### Charset
+
+Adding e.g. `?charset=iso-8859-1` overrides (and takes precedence over)
+the Charset from the Media Type (if any) or any HTTP header like mechanisms.
+
+### Integrity (TODO)
+
+We plan
+to support `?integrity=...`
+to verify resource integrity via a [cryptographic digest ("hash")])(https://docs.ipfs.tech/concepts/hashing/)
+using a [Multiformats's Multibase encoded Multihash](https://www.multiformats.io).
+This is similar e.g. to [HTML's Subresource Integrity (SRI)](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity).
