|
|
Fig. "XML for Map in Figure" shows the XML representation of the |
|
resource map shown in Fig. "Example of a Map in the Advanced Editor", |
|
which is the format in which maps are stored. 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<conditions> 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<The final syntax for conditions has not yet been |
|
determined.> |
