926: Fig. "XML for Map in Figure" shows the XML representation of the
927: resource map shown in Fig. "Example of a Map in the Advanced Editor",
928: which is the format in which maps are stored. In the figure, however,
929: additional graphical map layout information generated by the Advanced
930: Resource Assembly Tool is not displayed. This graphical information is
931: optional to re-generate the same graphical layout when the map is
932: brought up again in the Resource Assembly Tool, and is not needed for
933: any other system functionality.
934:
935: Maps can be generated by tools other than the Resource Assembly
936: Tool. In particular, an author might have some other representation of
937: a course sequence, which can be converted into a map using scripts. If
938: this map then were to be brought up in the Resource Assembly Tool, the
939: Tool would automatically generate a graphical layout for it. Each
940: entry of the map (resources, conditions and links) is stored in a
941: separate tag.
942:
943: Resources and conditionsX<conditions> have to have unique ID
944: numbers. These numbers are automatically generated by the Resource
945: Assembly Tool when the entry is first created, or added to the entries
946: when a map generated outside the Resource Assembly Tool is first
947: retrieved. They can also be assigned by custom scripts or added in by
948: hand.
949:
950: In the XML example, entry 1 is the start resource of the map. When
951: this map is accessed, the source (src) URL of this tag will be the
952: first resource rendered. Entry 2 is the finish resource of this
953: map. This resource will be the last resource in the sequence of
954: resources. Entry 6 is a problem resource with the given URL and title,
955: as well as the priority "mandatory". Entry 19 is a condition, which is
956: used by the link between entries 6, the problem, and 9, a
957: sequence. I<The final syntax for conditions has not yet been
958: determined.>
