+title: diaspora:// URI scheme
+---
+
+## Server and software independent links
+
+A `diaspora://` URL is used if a user wants to link to another post. It doesn't
+contain a server hostname so it is independent of the senders server. And it
+isn't software specific, it is thought to be compatible with every software
+that is compatible with the protocol, so the receiving software can display
+it as software specific URL. 
+
+The format is similar to the route used for [fetching][fetching], so if the
+receiving server doesn't know the linked entity yet, it can just be fetched.
+
+### Format
+
+`diaspora://:type/:guid`
+
+#### Parameters
+
+| Name   | Description                                    |
+| ------ | ---------------------------------------------- |
+| `type` | The type of the linked entity in `snake_case`. |
+| `guid` | The [GUID][guid] of the linked entity.         |
+
+#### Example
+
+`diaspora://post/17faf230675101350d995254001bd39e`
+
+[fetching]: {{ site.baseurl }}/federation/fetching.html
+[guid]: {{ site.baseurl }}/federation/types.html#guid
