algorithms. 1.1.1. ITEMS AND TYPES Unomi structures the information it collects using the concept of Item which provides the base information (an identifier and a type) the context server needs to process in the form of key-value pairs. These properties are further defined by the Item’s type definition which explicits the Item’s structure and semantics. By defining new types, users specify which properties server to filter data to only see relevant data. Base Item structure: { "itemType": item>, "scope": , "itemId": <item identifier>, "properties": } Some

In Wicket header items are HeaderItem (for example JavaScriptHeaderItem) ● A page or one of its component can add an header item overriding its method renderHead: class MyPanel extends Panel { public void renderHead(IHeaderResponse forReference(jqueryuiRef); Priority Header Item ● PriorityHeaderItem: wraps another header item and ensures that it will have the priority over the other items. The item wrapped by PriorityHeaderItem will
