The DIAL Index prototype has been constructed as an integral part of AustLII's World Law Index of law on the Internet, partly for technical reasons, but also because we are of the view that what we call a `multi-threaded index' is one of the likely options for making such an index sustainable at a reasonable cost. The idea is simply that a number of collaborators work together in the construction of a large Internet law index, with each stakeholder concentrating on building (or funding) one part of the index. So, for example, Project DIAL concentrates on the creation of pages of links relating to legislation, and legislation-related resources such as Parliamentary sites and law reform reports. These pages appear in World Law Index clearly identified or `badged' as `Project DIAL Index' pages, as illustrated in the screen examples in these chapters. However, there are many other pages in the index that have been built for other purposes, and these appear identified as general `World Law Index' pages or `badged' as part of some other specific and separately funded project (eg on indigenous legal issues). In both cases the separately funded resources can be separately identified, but this no impediment to the creation of a much larger facility than could be sustained for one project alone.
Similarly, in DIAL Search, there are a number of separately searchable Libraries, most of which reflect the emphasis of certain funding sources on targeting certain types of resources. Users can search `All Libraries' or can search the separate collections.
Editing is via an editable view of the actual pages in the index, as shown below. Selection of one of the editing functions leads to a form for that entry which may then be completed or amended.
 The `Add a Link' facility is at the top of pages in AustLII's World Law Index, but a customised version is yet to be added to the DIAL Index pages.
