[kepler-dev] Please anyone help me how display the workflow model result in browser.

[Jianwu Wang]

Hi Rajan,

    For Hydrant, which is one of Kepler Web UI project, it basically 
create a new MoML filter and a set of new classes which extend display 
related actors, like Display and PlotterBase, and rewrite their 
postfire/wrapup/... functions to display them at web page. Before the 
workflow is executed, the new filter should be set to change to display 
related actors. You can find more info of Hydrant at 
http://www.hpc.jcu.edu.au/projects/kepler/wiki/Hydrant.

    You can find the info of other Kepler WebUI projects at 
https://kepler-project.org/developers/interest-groups/webui

Best wishes

Sincerely yours
