+# Owner URL template
+
+It is possible for a client to build a URL that can be used by the user to see owner's page in their web
+browser. This is useful when a package source wants to show additional information about an owner that may not fit
+within the scope of what the NuGet client application shows.
+
+The resource used for building this URL is the `OwnerDetailsUriTemplate` resource found in the
+[service index](service-index.md).
+
+## Versioning
+
+The following `@type` values are used:
+
+@type value                     | Notes
+------------------------------- | -----
+OwnerDetailsUriTemplate/6.11.0  | The initial release
+
+## URL template
+
+The URL for the following API is the value of the `@id` property associated with one of the aforementioned
+resource `@type` values.
+
+## HTTP methods
+
+Although the client is not intended to make requests to the owner URL on behalf of the user, the web page
+should support the `GET` method to allow a clicked URL to be easily opened in a web browser.
+
+## Construct the URL
+
+Given a known owner ID, the client implementation can construct a URL used to access a web interface. The
+client implementation should display this constructed URL (or clickable link) to the user allowing them to open a web
+browser to the URL and to learn more about the owner. The contents of the owner page is determined by the
+server implementation.
+
+The URL must be an absolute URL and the scheme (protocol) must be HTTPS.
+
+The value of the `@id` in the service index is a URL string containing any of the following placeholder tokens:
+
+### URL placeholders
+
+Name        | Type    | Required | Notes
+----------- | ------- | -------- | -----
+`{owner}`   | string  | no       | The owner ID to get details for
+
+The server should accept `{owner}` value with any casing.
+
+For example, nuget.org's package details template looks like this:
+
+```http
+https://www.nuget.org/profile/{owner}
+```
+
+If the client implementation needs to display a link to the package details for NuGet.Versioning 4.3.0, it would
+produce the following URL and provide it to the user:
+
+```http
+https://www.nuget.org/profiles/nuget
+```
