Visualize Functional Profile
Given the complexity of the models in use, and the large number, users are constantly confronted with the problem of trying to gain an understanding of new domains not familiar to them. Visualizations of models and vocabularies are perceived as essential to this task. The requirement is to provide visualizations that are easy to navigate, that identify the contact points between models and between vocabularies and that allow users to seamlessly move from model constructs to data.
Capability Elaborations
This Functional Profile includes, but is not limited to, the following capability elaborations:
...
Derived From Requirements
- Gap Analysis::Visualize::038 - Visualize and navigate whole models Provide a means to visualize the models that have been loaded into the KR. The UML Model Browser displays the granular details of a model in list format, but there isn't away to visualize and navigate the whole model. The grid portal provides this feature from the metadata, there should be a way to do this when viewing models in the KR. This would enhance a potential new user’s ability to determine if they can use all or part of a model.
- Gap Analysis::CDISC::CDISC-6 - Provide enhanced visualization, browsing and search tools The ability to navigate, search, order, group (predefined & ad-hoc), and compare data element definitions, associations, and code lists is a requirement for defining CDISC standards. In the CDISC SHARE (Shared Health and Research Electronic Library) Pilot it was very difficult to navigate/search/compare definitions; the semantic Wiki did not provide good tooling for these capabilities. There was no ability to display, order, and align any code sets or their associations with data elements. KR Searching capabilities should include ad hoc views, pre-defined views, wild card, and synonym searches, ignore word stems, the exclusion of some results, and the ability to search/view hierarchies. Other search capabilities include control over which objects to search, the ability to view results and data element display by source or other criteria. In addition, the LED displays did not provide enough visual real-estate. This includes the display of horizontal and vertical data structures. A big CDISC problem is that most standards developers are content experts and not information modelers or IT experts. Generally, they are volunteers who meet once a week. They also have a few content curators, technical data modelers as well as technical experts. An easy-to-use asynchronous collaboration environment is central to the success of their CDISC standards work. *Source: * * 5/20/2010 Interview, David Iberson-Hurst * CDISC Share Pilot Report and CDISC Requirements Package 1 - NCI Semantic Infrastructure, 5/28/2010, Section 2.1 & Section 2.2, Section 2.3
