Hi,
Currently, work being done to simplify the running of workflows. It is
planned to be able to run them from a web application so that novice users
of Taverna don't have to use the workbench. This poses the problem of how to
automatically generate an interface for inputting into a workflow and how to
present the results.
The information in a workflow file is not detailed enough to generate an
adequate interface. Work is being done in Manchester and Halle on creating a
meta-language for generating an interface to a workflow and displaying its
output. This meta-language would provide extra information on the inputs and
outputs of a workflow defined by an expert. So, for the inputs it could
provide the following information:
- The UI component for input (text area, checkbox etc.)
- The type of data that was expected (string, integer, file etc.)
- The range of values (x >10, only GATC etc.)
- Pattern checking (must contain �...@’, file extensions etc.)
The output values should be able to define how to display the workflow’s
results e.g. in a table or plain text and describe the layout of the results
on the page.
If anyone has any comments about this project or is involved in something
similar we would be happy to hear about it. Thanks.
Rory
