In the figure, however, +additional graphical map layout information generated by the Advanced +Resource Assembly Tool is not displayed. This graphical information is +optional to re-generate the same graphical layout when the map is +brought up again in the Resource Assembly Tool, and is not needed for +any other system functionality. + +Maps can be generated by tools other than the Resource Assembly +Tool. In particular, an author might have some other representation of +a course sequence, which can be converted into a map using scripts. If +this map then were to be brought up in the Resource Assembly Tool, the +Tool would automatically generate a graphical layout for it. Each +entry of the map (resources, conditions and links) is stored in a +separate tag. + +Resources and conditionsX have to have unique ID +numbers. These numbers are automatically generated by the Resource +Assembly Tool when the entry is first created, or added to the entries +when a map generated outside the Resource Assembly Tool is first +retrieved. They can also be assigned by custom scripts or added in by +hand. + +In the XML example, entry 1 is the start resource of the map. When +this map is accessed, the source (src) URL of this tag will be the +first resource rendered. Entry 2 is the finish resource of this +map. This resource will be the last resource in the sequence of +resources. Entry 6 is a problem resource with the given URL and title, +as well as the priority "mandatory". Entry 19 is a condition, which is +used by the link between entries 6, the problem, and 9, a +sequence. I +=cut
