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