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