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.> |
