I still do not quite understand "I need to know wich are all the special annotations that SMW use." Do you mean that you need to know all the *names of special properties* that SMW uses? Or are you interested in their *stored values* for a particular page? A "special property" in SMW is "special" because it has a predefined datatype and an internal ID. Other than this, the special properties are just like normal properties. In particular, there is no fixed set of special properties. Extensions can add their own properties to store special information that they need. There is a list of currently registered special properties together with their type, but SMW does not currently have a method to retrieve this list (it was not needed so far). You can see the default special properties in ./includes/dataitems/SMW_DI_Property.php in method initPropertyRegistration() where this list is initialised. Also note that special properties have an ID and a datatype, but they may or may not have a user-readable label that can be used in the wiki (in queries or annotations). Special properties that are not labelled are used internally to store data that is not directly relevant to the user. So you cannot find all special properties in the user manual: some of them are not visible to users at all. The user labels, if any, are defined in the SMW_Language.php files in ./languages/ and of course they are different for each language. You can use SMWDIProperty::findPropertyLabel() to get the label of a special property in the current wiki language.
