anchor.diff:  == Contents
   
   Contents are similar to tags with one major exception. Contents can not be nested. This means a content does not have a parent child relationship to another content. Only tags have this kind of relationship. A content can only have one parent tag. Contents can be tagged by any number of tags.

  +Contents can be manipulated using the ContentVerticle class.
   
   === Object Relationships
   
  
positive.code: 
  Following a link to a page that does not exist in the current language leads to a mediator page. The mediator page informs the user that the content is not available in the current language, but available in english, german etc.
  
  Links CAN include the target language
  
  
  == Paging
  
  * /tags
  * /contents
  
  Tags have tags and cildren. Both can be filtered and paged individually within the tag or content response.
  
  == Schemas 
  
  
negative.code: A tag must only have a single parent.
  
  The root Tag of a project can not be deleted.
  Schemas can be manipulated using the ObjectSchemaVerticle class.
  Schema updates must directly be synchronized with all affected contents.
  
  == Microschemas
  
  A microschemas is a blueprint for a content element that can be added to a content property. In this way it is similar to a schemas.
  Typical examples for microschemas are image galleries, vcard boxes, text segments.
  Microschemas can not be nested. Content elements that were created using microschemas can be sorted within the context of the parent content property.
  The schema for the content defines property types that can be used when creating a new content. It is possible to set a whitelist of microschemas for a property type. When whitelisting microschemas it is not possible to insert a content element of an microschema type that is not allowed by the whitelist. 
  A microschema can contain references to a binary contents. This is important if a microschemas is used to create a datastructure for an image gallery.
