130:
131: Fig. "XML for Map in Figure" shows the XML representation of the
132: resource map shown in Fig. "Example of a Map in the Advanced Editor",
133: which is the format in which maps are stored. In the figure, however,
134: additional graphical map layout information generated by the Advanced
135: Resource Assembly Tool is not displayed. This graphical information is
136: optional to re-generate the same graphical layout when the map is
137: brought up again in the Resource Assembly Tool, and is not needed for
138: any other system functionality.
139:
140: Maps can be generated by tools other than the Resource Assembly
141: Tool. In particular, an author might have some other representation of
142: a course sequence, which can be converted into a map using scripts. If
143: this map then were to be brought up in the Resource Assembly Tool, the
144: Tool would automatically generate a graphical layout for it. Each
145: entry of the map (resources, conditions and links) is stored in a
146: separate tag.
147:
148: Resources and conditionsX<conditions> have to have unique ID
149: numbers. These numbers are automatically generated by the Resource
150: Assembly Tool when the entry is first created, or added to the entries
151: when a map generated outside the Resource Assembly Tool is first
152: retrieved. They can also be assigned by custom scripts or added in by
153: hand.
154:
155: In the XML example, entry 1 is the start resource of the map. When
156: this map is accessed, the source (src) URL of this tag will be the
157: first resource rendered. Entry 2 is the finish resource of this
158: map. This resource will be the last resource in the sequence of
159: resources. Entry 6 is a problem resource with the given URL and title,
160: as well as the priority "mandatory". Entry 19 is a condition, which is
161: used by the link between entries 6, the problem, and 9, a
162: sequence. I<The final syntax for conditions has not yet been
163: determined.>
