Integer	fpdt:Integer	A real number that contains no fractional part (e.g. 42).
Link	fpdt:Link	A link from one element to another. The target can be either in this workspace, or in another workspace.
List	fpdt:List	A list is a collection of either text attributes or link attributes.
Lock	fpdt:Lock	A selection of attributes that can be locked from editing. When the lock attribute is activated for an element the attributes selected in the lock attribute cannot be edited and the element cannot be deleted.

URL	fpdt:Url	A link to a specific resource on the Internet (e.g. http://www.ibm.com).
Unique id	fpdt:UniqueId	A text field where the value must be unique. When new elements are created, the unique id attribute is automatically assigned a unique value.
Version	fpdt:Version	A number or character that automatically increases based on changes in other attributes.

fpdt:CheckBox

The primary value is the boolean literal, i.e. the object of the fpdt:value property.

fpdt:Date

The primary value is the date-time literal, i.e. the object of the fpdt:value property.

fpdt:Heading

None.

The is a pseudo-attribute used for organizing other attributes. It has no primary value.

fpdt:Link

The primary value is the resource URI, i.e. the object of the fpdt:link property.

fpdt:Text

The primary value is the XHTML literal, i.e. the object of the fpdt:formattedTextValue property.

fpdt:TimeGrid

TimeGrids are tables of values. These should be represented as RDF where each row, column, and cell is a resource. However, since these are parts of the table, they should be represented as URI references based on the table. The table should be a top level, dereferenceable resource. The value of a TimeGrid attribute is therefore a link to the TimeGrid value. See below for details.

fpdt:UniqueId

The primary value is the string literal, i.e. the object of the fpdt:value property.
