! 873:
! 874: Fig. "XML for Map in Figure" shows the XML representation of the
! 875: resource map shown in Fig. "Example of a Map in the Advanced Editor",
! 876: which is the format in which maps are stored. In the figure, however,
! 877: additional graphical map layout information generated by the Advanced
! 878: Resource Assembly Tool is not displayed. This graphical information is
! 879: optional to re-generate the same graphical layout when the map is
! 880: brought up again in the Resource Assembly Tool, and is not needed for
! 881: any other system functionality.
! 882:
! 883: Maps can be generated by tools other than the Resource Assembly
! 884: Tool. In particular, an author might have some other representation of
! 885: a course sequence, which can be converted into a map using scripts. If
! 886: this map then were to be brought up in the Resource Assembly Tool, the
! 887: Tool would automatically generate a graphical layout for it. Each
! 888: entry of the map (resources, conditions and links) is stored in a
! 889: separate tag.
! 890:
! 891: Resources and conditionsX<conditions> have to have unique ID
! 892: numbers. These numbers are automatically generated by the Resource
! 893: Assembly Tool when the entry is first created, or added to the entries
! 894: when a map generated outside the Resource Assembly Tool is first
! 895: retrieved. They can also be assigned by custom scripts or added in by
! 896: hand.
! 897:
! 898: In the XML example, entry 1 is the start resource of the map. When
! 899: this map is accessed, the source (src) URL of this tag will be the
! 900: first resource rendered. Entry 2 is the finish resource of this
! 901: map. This resource will be the last resource in the sequence of
! 902: resources. Entry 6 is a problem resource with the given URL and title,
! 903: as well as the priority "mandatory". Entry 19 is a condition, which is
! 904: used by the link between entries 6, the problem, and 9, a
! 905: sequence. I<The final syntax for conditions has not yet been
! 906: determined.>
