Hi,
Dynamics CRM 2011 supports a rich REST based endpoint allowing Javascript, Silverlight and other resources to access your CRM data. The latest CRM 2011 SDK contains some (beta) details on the request and response structures needed to perform the CRUD operations.
These CRM 2011 web services also support the OData Protocol and $select, $filter, $orderbyand $top can be applied to a query string request to return ATOM formatted data to your client application. For example, operations against the Contact recordset cover
$Select
Select specific columns from the ContactSet using
https://.../organizationdata.svc/ContactSet?$select=FullName,Address1_Country
or select the Contact Fullname and the Parent Customer record
https://.../organizationdata.svc/ContactSet?$select=FullName,ParentCustomerId
In the resultset, the Parent Customer ID is resolved to a record id (GUID) and, by default, includes the Primary Field of the related record (as we would expect with CRM)
$orderby
The sort order can be specified with the $orderby clause, for example
https://.../organizationdata.svc/ContactSet?$select=FullName,Address1_Country&$orderby=FullName desc
$top
You can also limit the number of records returned using the $top clause, for example the first 5 records ordered by descending FullName is
https://.../organizationdata.svc/ContactSet?$select=FullName,Address1_Country&$orderby=FullName desc&$top=5
$Filter
Search for all the Contacts in the country of Ireland is possible with
https://.../organizationdata.svc/ContactSet?$filter=Address1_Country%20eq%20'Ireland'

Enjoy CRM !!!
