IODF attribute table

The following table describes the names and the properties of the attributes. The first column additionally shows the alias names in parentheses where available.

Notes:
  1. The Access Class for all attributes is normal.
  2. All attribute type names ending with the plural s represent multi-valued attributes. HCD interprets the values as an ordered list. This is important if there are two lists which have corresponding list items.
  3. In a request, a mix of base names and alias names for attributes is not supported.
