Land Parcel Identification System

Form User Interface Toolkit
Giselle includes a rich set of tools and components facilitating the development and configuration of applications which support a business process of the client’s organisation. Forms can  be easily defined in an XML file, and rendered in a thick-client Java application or in a HTML web application (Figure 2).

The attribute characteristics of the land parcels and other data entries are edited via a fully configurable user-friendly attribute form. The flexible configuration of the user interface is very important, because it allows for  precise control over the display and behavior of the attribute forms and enables procedural changes and updates of the attribute data constraints to be implemented efficiently, while ensuring the validity of the entered data. Properties of the individual fields, which can be adjusted painlessly via XML configuration, include the following:

• label text and description (shown as tooltip text)
• visibility, enabled/disabled state,
• data type (string, integer, double, date,…) and its length (string) or range (integer, double)
• read-only and not-null,
• default value
• regular expression constraints (allow only certain characters, define custom rules for special strings e.g. postal code)
• list-of-values constraints (values, as well as their colors and description can be read from the database)
• dependencies – constraints for individual fields can change according to values of other fields (e.g. comment should not be empty when selected parcel type is ‘OTHER’)
