Pack: Trident Example Workflows

Description:

This workflow contains conditional processing. Trident does not have a good visualization for these yet, but it is good to see how conditionals work.

Description:

This workflow reads data from a netCDF file and sends out a message to COVE (collaborative ocean visualization environment). COVE reads the netCDF data and renders that.

Description:

The Cove workflow reads oceanographic NetCDF data, does a simple processing step, writes the data out, then sends a web service message to the COVE visualization tool. It is a four step, sequential workflow.

Description:

This workflow shows both parallel and sequential elements. Input files are read in parallel and the resulting output shared with later activities.

Description:

This WF is a sample which shows support of common programming constructs within Trident. The If workflow has two parts; the condition block which generates a TRUE or FALSE condition and two parallel branches for ‘If’ and ‘Else’.

Description:

This WF reads two netCDF files to two hyper cube data structures. Then this workflow uses the HyperCubeDiffTransform activity to perform difference operation between the values of a netCDF variable read from the two files. The WF generates a difference cube as output.

Description:

This WF reads a netCDF file to a hyper cube data structure. Then this WF applies the mean transform to a variable in the netCDF file. The calculated mean is produced as part of the output.

Description:

This WF shows how to use while constructs in workflows. The condition block generates a true or false condition. The while loop is executed once, each time the condition is true.

Description:

This WF downloads a web page and converts the content from HTML to XSL.
