Tim Lebo Escience Provenance Gregory Todd Williams 1

Question is for the Presentation: Zhao2004using presented by Tim Lebo 9 oct 2008
Question is asked by: Gregory Todd Williams
The Question is: The use of Haystack as a means of showing provenance data to scientists seems like a potentially poor choice. In particular, the interface shown in Figure 5 seems overly complex, making it difficult to easily understand relationships between concepts. A feature of Haystack is mentioned allowing complex graphs to be rendered as "user interface screens that behave like the much more familiar frames of web pages." This alternate UI is not shown, however. Do you think a compelling interface for this type of provenance data could be developed based solely on the schema ontology, or might custom interfaces that rely on the domain specific ontologies be required on a per-project basis?
