<strong>DICE</strong> <strong>Final</strong> <strong>Report</strong><br />

Figures 11 illustrates the exemplar result list named ‘john maynard keynes’ being saved <strong>and</strong> Figure<br />

12 shows that a web page is displayed indicating that the results were saved successfully. An error<br />

message is displayed if the account details can’t be authenticated.<br />

Returning to the COSE interface, shown in Figure 13 we can see that a new resource list named<br />

‘john maynard keynes’ (c.f. Figure 6) appears in the top level folder with a timestamp indicating<br />

when it was generated.<br />

Figure 13. New resource list saved the <strong>Resource</strong> <strong>Discovery</strong> interface<br />

Clicking twice on the named list, as in Figure 14, we can see the results displayed in a similar<br />

format to the results returned in D+, with additional header information indicating the source of the<br />

search (target) <strong>and</strong> the query term. This requires further work to fully capture <strong>and</strong> present result<br />

descriptions (metadata). Whereas D+ renders results by XSL transformations of the results data (in<br />

SRW xml format), results presented in COSE depend on parsing the results data <strong>and</strong> presenting<br />

this as HTML using the D+ style sheet, avoiding the overhead of building the transform engine into<br />

COSE.<br />

Though resource lists have their own COSE icon, there is a lot more work to render them as a fullblown<br />

COSE (learning) objects 10 . However, because they are associated with an HTML component<br />

generated in parallel, they can in effect be retrieved as text components using COSE.<br />

10 This requires updating COSE code to accommodate them as a (page set) component in browsing,<br />

editing, publication, sharing, export, searching, use in various other tools etc., <strong>and</strong> so is beyond the<br />

remit of the project.<br />
