+ "IT Mill Toolkit data model is one of the core concepts "
+ "in the library and Property-interface is the base of that "
+ "model. Property provides standardized API for a single data object "
+ "that can be read (get) and written (set). A property is always typed, but can optionally "
+ "support data type conversions. Optionally properties can provide "
+ "value change events for following the state changes."
+ "<br /><br />The most important function of the Property as well as other "
+ "data models is to connect classes implementing the interface directly to "
+ "editor and viewer classes. Typically this is used to connect different "
+ "data sources to UI components for editing and viewing their contents."
+ "<br /><br />Properties can be utilized either by implementing the interface "
+ "or by using some of the existing property implementations. IT Mill Toolkit "
+ "includes Property interface implementations for "
+ "arbitrary function pairs or Bean-properties as well as simple object "
+ "properties."
+ "<br /><br />Many of the UI components also implement Property interface and allow "
+ "setting of other components as their data-source. These UI-components "
+ "include TextField, DateField, Select, Table, Button, "
+ "Label and Tree.";
