Secure Web service call example (1)

• Download

This is an example of a workflow that contains a call to a secure Web service that runs behind HTTPS and requires user to authenticate. The first thing you can expect to see is a pop up dialog asking if you trust the Web service to be invoked over HTTPS. You can use testuser/testpasswd as username and password for authentication when running the workflow. To see where the security is being configured, right-click the service in the diagram and select "Configure security" from the menu. You m...

Example workflow for REST and XPath activi... (1)

• Download

This workflow fetches weather forecast for the user-specified location. First of all it uses the provided location name to obtain a WOEID ("Where On Earth ID") of that location, then uses that unique identifier to fetch the weather forecast from Yahoo server. Multiple results may be obtained in case there is no unique translation of the location to a WOEID. REST activity is used to perform HTTP requests and fetch data from remote servers; XPath activity is then used to parse the XML data a...

Example of explicit looping (1)

• Download

This workflow demonstrates how a nested workflow can be called an explicit number of times. Note that the loop iterator does not need to be used in the logic of the loop contents. It can be used as a sentinel (see the conditional workflow)

Example for external tools with zip and unzip (1)

• Download

This workflow only works on a Unix machine. This workflow takes a fixed URL from which a text file is downloaded (output as Original_file). That file is zipped (output as Zipped_File) and then unzipped again (output as Unzipped_File). The orginal file and the unzipped version are then diff'd/

EBI_InterproScan_NewServices (2)

• Download

This workflow performs an interproscan at the EBI on sequences provided as input. The output is provided as text and xml. This workflow uses the new EBI services, which are asynchronous and require looping over the nested workflow (Status) until the workflow has finished. Many of the EBI services now work in this way, so you can use this workflow as an example of the invocation pattern and looping configuration.

calculateFieldline by SINP (5)

• Download

Workflow for Taverna based on the IMPEx-FP7 method calculateFieldLine. This method can be used to return the field lines (calculated by SINP PMM), which start in given points inside the planetary magnetosphere and in different time moments for each point, and the magnetic field along these lines.

calculateDataPointValue by SINP (3)

• Download

Workflow for Taverna based on the IMPEx-FP7 method calculateDataPointValue. This method can be used to return the magnetic field (calculated by SINP PMM) in given points inside the planetary magnetosphere and in different time moments for each point.

getMostRelevantRun by FMI (3)

• Download

Workflow for Taverna based on the IMPEx-FP7 method getMostRelevantRun. This method is intended to help users to find those simulation runs in SMDB's tree.xml file whose input parameters best match the given solar wind conditions. For each simulation run in the tree.xml file the method computes a 'difference index'. This 'difference index' is a sum of individual difference indices (one for each solar wind parameter defined in the input parameter set).

getFileUrl by LATMOS (5)

• Download

Workflow for Taverna based on the IMPEx-FP7 method getFileURL. This method fetches precomputed data, i.e. already calculated values along a given spacecraft trajectory.

getFieldline by LATMOS (3)

• Download

Workflow for Taverna based on the IMPEx-FP7 method getFieldLine. This method computes field lines or stream lines inside the simulation box. The user will provide a set of 3D position coordinates which act as starting points for the field/stream line tracing. The tracing may be performed forwards, backwards or both. The method will return an URL to a VOTable file which contains the field/stream lines as a set of 3D position coordinates and the requested physical quantities at these points.
