+# SilverStripe RestfulServer Module
+
+## Overview
+
+This class gives your application a RESTful API.  All you have to do is define static $api_access = true on
+the appropriate DataObjects.  You will need to ensure that all of your data manipulation and security is defined in
+your model layer (ie, the DataObject classes) and not in your Controllers.  This is the recommended design for SilverStripe
+applications.
+
+## Requirements
+
+ * SilverStripe 3.0 or newer
+
+## Configuration
+
+Enabling restful access on a model will also enable a SOAP API, see `SOAPModelAccess`.
+
+Example DataObject with simple api access, giving full access to all object properties and relations,
+unless explicitly controlled through model permissions.
+
+	class Article extends DataObject {
+		static $db = array('Title'=>'Text','Published'=>'Boolean');
+		static $api_access = true;
+	}
+
+Example DataObject with advanced api access, limiting viewing and editing to Title attribute only:
+
+	class Article extends DataObject {
+		static $db = array('Title'=>'Text','Published'=>'Boolean');
+		static $api_access = array(
+			'view' => array('Title'),
+			'edit' => array('Title'),
+		);
+	}
+
+## Supported operations
+
+ - `GET /api/v1/(ClassName)/(ID)` - gets a database record
+ - `GET /api/v1/(ClassName)/(ID)/(Relation)` - get all of the records linked to this database record by the given reatlion
+ - `GET /api/v1/(ClassName)?(Field)=(Val)&(Field)=(Val)` - searches for matching database records
+ - `POST /api/v1/(ClassName)` - create a new database record
+ - `PUT /api/v1/(ClassName)/(ID)` - updates a database record
+ - `PUT /api/v1/(ClassName)/(ID)/(Relation)` - updates a relation, replacing the existing record(s) (NOT IMPLEMENTED YET)
+ - `POST /api/v1/(ClassName)/(ID)/(Relation)` - updates a relation, appending to the existing record(s) (NOT IMPLEMENTED YET)
+
+ - DELETE /api/v1/(ClassName)/(ID) - deletes a database record (NOT IMPLEMENTED YET)
+ - DELETE /api/v1/(ClassName)/(ID)/(Relation)/(ForeignID) - remove the relationship between two database records, but don't actually delete the foreign object (NOT IMPLEMENTED YET)
+ - POST /api/v1/(ClassName)/(ID)/(MethodName) - executes a method on the given object (e.g, publish)
+
+## Search
+
+You can trigger searches based on the fields specified on `DataObject::searchable_fields` and passed
+through `DataObject::getDefaultSearchContext()`. Just add a key-value pair with the search-term
+to the url, e.g. /api/v1/(ClassName)/?Title=mytitle.
+
+## Other url-modifiers
+
+- `&limit=<numeric>`: Limit the result set
+- `&relationdepth=<numeric>`: Displays links to existing has-one and has-many relationships to a certain depth (Default: 1)
+- `&fields=<string>`: Comma-separated list of fields on the output object (defaults to all database-columns).
+  Handy to limit output for bandwidth and performance reasons.
+- `&sort=<myfield>&dir=<asc|desc>`
+- `&add_fields=<string>`: Comma-separated list of additional fields, for example dynamic getters.
+
+## Access control
+
+Access control is implemented through the usual Member system with Basicauth authentication only.
+By default, you have to bear the ADMIN permission to retrieve or send any data.
+You should override the following built-in methods to customize permission control on a
+class- and object-level:
+
+- `DataObject::canView()`
+- `DataObject::canEdit()`
+- `DataObject::canDelete()`
+- `DataObject::canCreate()`
+
+See `DataObject` documentation for further details.
+
+You can specify the character-encoding for any input on the HTTP Content-Type.
+At the moment, only UTF-8 is supported. All output is made in UTF-8 regardless of Accept headers.

+/**
+ * Generic RESTful server, which handles webservice access to arbitrary DataObjects.
+ * Relies on serialization/deserialization into different formats provided
+ * by the DataFormatter APIs in core.
+ * 
+ * @todo Finish RestfulServer_Item and RestfulServer_List implementation and re-enable $url_handlers
+ * @todo Implement PUT/POST/DELETE for relations
+ * @todo Access-Control for relations (you might be allowed to view Members and Groups, but not their relation with each other)
+ * @todo Make SearchContext specification customizeable for each class
+ * @todo Allow for range-searches (e.g. on Created column)
+ * @todo Allow other authentication methods (currently only HTTP BasicAuth)
+ * @todo Filter relation listings by $api_access and canView() permissions
+ * @todo Exclude relations when "fields" are specified through URL (they should be explicitly requested in this case)
+ * @todo Custom filters per DataObject subclass, e.g. to disallow showing unpublished pages in SiteTree/Versioned/Hierarchy
+ * @todo URL parameter namespacing for search-fields, limit, fields, add_fields (might all be valid dataobject properties)
+ *       e.g. you wouldn't be able to search for a "limit" property on your subclass as its overlayed with the search logic
+ * @todo i18n integration (e.g. Page/1.xml?lang=de_DE)
+ * @todo Access to extendable methods/relations like SiteTree/1/Versions or SiteTree/1/Version/22
+ * @todo Respect $api_access array notation in search contexts
