Attribute Data

Attribute data is non-graphical information assigned to editable graphical items, SIS Workspace Definitions (SWDs), overlays and datasets.

An Attribute is simply a type of property; it is however different from a system property (which is an integral part of the item, SWD, dataset or overlay).

Once an attribute has been attached to an Item, you can see it displayed in the Properties Control Bar along with the system properties for that Item.

Microsoft Visual Basic customisations can be used to add, modify and remove attribute data with all SIS products.

Once you have created attribute data on an Item, it will be retained even when the item is edited.

Attribute data is stored inside the Item (and not in a separate table). This means attribute data is never "lost" when individual files are deleted.
