918: =end latex
919:
920: Fig. "XML for Map in Figure" shows the XML representation of the
921: resource map shown in Fig. "Example of a Map in the Advanced Editor",
922: which is the format in which maps are stored. In the figure, however,
923: additional graphical map layout information generated by the Advanced
924: Resource Assembly Tool is not displayed. This graphical information is
925: optional to re-generate the same graphical layout when the map is
926: brought up again in the Resource Assembly Tool, and is not needed for
927: any other system functionality.
928:
929: Maps can be generated by tools other than the Resource Assembly
930: Tool. In particular, an author might have some other representation of
931: a course sequence, which can be converted into a map using scripts. If
932: this map then were to be brought up in the Resource Assembly Tool, the
933: Tool would automatically generate a graphical layout for it. Each
934: entry of the map (resources, conditions and links) is stored in a
935: separate tag.
936:
937: Resources and conditionsX<conditions> have to have unique ID
938: numbers. These numbers are automatically generated by the Resource
939: Assembly Tool when the entry is first created, or added to the entries
940: when a map generated outside the Resource Assembly Tool is first
941: retrieved. They can also be assigned by custom scripts or added in by
942: hand.
943:
944: In the XML example, entry 1 is the start resource of the map. When
945: this map is accessed, the source (src) URL of this tag will be the
946: first resource rendered. Entry 2 is the finish resource of this
947: map. This resource will be the last resource in the sequence of
948: resources. Entry 6 is a problem resource with the given URL and title,
949: as well as the priority "mandatory". Entry 19 is a condition, which is
950: used by the link between entries 6, the problem, and 9, a
951: sequence. I<The final syntax for conditions has not yet been
952: determined.>
