987:
988: Fig. "XML for Map in Figure" shows the XML representation of the
989: resource map shown in Fig. "Example of a Map in the Advanced Editor",
990: which is the format in which maps are stored. In the figure, however,
991: additional graphical map layout information generated by the Advanced
992: Resource Assembly Tool is not displayed. This graphical information is
993: optional to re-generate the same graphical layout when the map is
994: brought up again in the Resource Assembly Tool, and is not needed for
995: any other system functionality.
996:
997: Maps can be generated by tools other than the Resource Assembly
998: Tool. In particular, an author might have some other representation of
999: a course sequence, which can be converted into a map using scripts. If
1000: this map then were to be brought up in the Resource Assembly Tool, the
1001: Tool would automatically generate a graphical layout for it. Each
1002: entry of the map (resources, conditions and links) is stored in a
1003: separate tag.
1004:
1005: Resources and conditionsX<conditions> have to have unique ID
1006: numbers. These numbers are automatically generated by the Resource
1007: Assembly Tool when the entry is first created, or added to the entries
1008: when a map generated outside the Resource Assembly Tool is first
1009: retrieved. They can also be assigned by custom scripts or added in by
1010: hand.
1011:
1012: In the XML example, entry 1 is the start resource of the map. When
1013: this map is accessed, the source (src) URL of this tag will be the
1014: first resource rendered. Entry 2 is the finish resource of this
1015: map. This resource will be the last resource in the sequence of
1016: resources. Entry 6 is a problem resource with the given URL and title,
1017: as well as the priority "mandatory". Entry 19 is a condition, which is
1018: used by the link between entries 6, the problem, and 9, a
1019: sequence. I<The final syntax for conditions has not yet been
1020: determined.>
