... data here ...


Response is the standard property XML

<property name="{text}" href="{uri}" etag="{text}">
  <contents type="{text}" href="{uri}">{text}</contents>
  <user.modified id="{int}" href="{uri}">

Implementation Notes

  • The response XML will contain the contents text only for text based mimetypes with values less than 2048 chars in length. Otherwise the contents is available at the URI pointed to by property/contents/@href.
  • A user may only read and write their own properties. Admins can read/write anyones users properties.

C# Sample: Add User Property

The following code authenticates and creates a new user property named 'foo' with a text value. A description of the change is set as well.

Sample code 

Plug p = Plug.New("http://devwiki/@api/deki");  
p.At("users", "authenticate")  
 .WithCredentials("sysop", "password")
p.At("users", "current", "properties")
 .WithHeader("Slug", "foo")
 .With("description", "initial value")
 .Post(DreamMessage.Ok(MimeType.TEXT_UTF8, "My Value"));

Sample response from executing code 

<property name="foo" href="http://devwiki/@api/deki/users/1/properties/foo/info" etag="4463.r1_ts2009-03-20T22:48:15Z">
 <contents type="text/plain; charset=utf-8" href="http://devwiki/@api/deki/users/1/properties/foo">My Value</contents>
 <user.modified id="1" href="http://devwiki/@api/deki/users/1">
 <change-description>initial value</change-description>

Curl Sample: Add User Property

The following command adds a user property with property name "foo" and pairs it with the data from file "bar". The user name is "user".

Sample Code

curl -u username:password -H "Content-Type: text/plain" -H "Slug: foo" -d @bar -i http://mindtouch.address/@api/deki/users/=user/properties

Implementation notes 

curl flags

Basic HTTP authentication. Sends a username and password to server so it can verify whether a user is of privilege to perform specific operation.
-d @file
Specifies a POST request and the data file to send.
Replaces or appends an HTTP header. The "Slug" header designates the property name. The "Content-Type" header specifies the MIME type of the value attached to the property.
Includes the HTTP response header in the output. Useful for debugging.


Properties can contain any type of file, therefore it is important to specify the correct MIME when creating a property. For instance, a text property will require a text/plain header, xml will require application/xml header, a jpeg image will require image/jpg header, and so on.



We want to create a simple text property for the user Batman. The property name is "alterego" and the value is "Bruce Wayne", as outlined in "userprop.txt".


Content-Type: text/plain

Bruce Wayne

Sample Code

curl -u username:password -H "Content-Type: text/plain" -H "Slug: alterego" -d @userprop.txt -i

  • In order for properties to be displayed in "Page Properties" pages, the property name must be prefixed with "", otherwise it will remain hidden.
  • The easiest way to view properties if they do not appear in the UI is by accessing the XML file for the page properties. For example, the XML for the above path is <>.
