Wings Workflow System Tutorial

We have on-line hands-on tutorial materials for three different types of users of Wings:



Tutorials for Workflow Users

These are users that want to browse and execute workflows that are already pre-defined in the system by others. We give you an easy overview of Wings based on a public ''Portal'' (a place to play around). You can also create your own workflows using components that others have already pre-defined. Wings works in the browser, so there is no software to install if you use our web site and you can get started right away.

Here is an introductory tutorial for a workflow user. The tutorial assumes that you are working on the Wings Portal. It covers the following topics:

  1. Viewing a Workflow
  2. Setting Up a Workflow by Selecting Data and Parameters
  3. Executing a Workflow
  4. Viewing Execution Results

It also describes how a workflow user can take advantage of these unique features of Wings:

  1. Getting Wings to Help Set Up Workflow Parameters
  2. Getting Wings to Help You Find Relevant Datasets
  3. Getting Wings to Manage the Parallel Processing of Collections of Data
  4. Getting Wings to Validate Your Workflow
  5. Getting Wings to Specialize an Abstract Workflow

As a more advanced user, you can also:

  1. Upload More Data


Tutorials for Workflow Developers

These are users that want to create workflows using their own workflow components. For this, we have set up a second public site where you can test your own components and workflows without having to install any software.(requires login, email us to set up an account) .
Here are some tutorials for advanced users that want to create new workflows and workflow components:

There are two ways to start developing your own templates in WINGS:

  1. Create your own domain.
  2. Use templates from other people's domains as a starting point and adapt their templates to your needs.
    • If another workflow developer has already created templates that include parts you wish to repurpose for your own workflow needs, you can download their domain into your user account. This way you can edit, add, and delete parts of workflows without affecting the work of others.
    • In order to transfer a domain, the owner of that domain will have to download the domain from the "Manage Domains" page of their WINGS account. They can then send you a zip file with that domain, which you can then upload into your account from the "Manage Domains" page. Click "Add" and select the option for "Import Domain."
    • You can now edit the domain as you need to, but still make sure to follow the tutorial below and read the user tips.

User Tips

  • General
    • Name choices: Make sure to leave no spaces in the names of categories, components, data types, file names, etc.. Double check that you do not have an extra spaces before saving. If you get an error message when you try to save your work, it is very possible that you have an extra space.
    • Designing ahead: Design the workflow before creating components. This will avoid having to go back and change components and workflows once you have begun creating a new template.
    • Documentation: Make sure to provide documentation for both your templates and your components. Proper documentation allows others to follow and reuse your workflows. Description of needed data sets is also important.
  • Components
    • Changes: If you change a component, and a workflow contains this component, then the workflow must be erased and recreated in order to incorporate the new definition of the component.
    • Collections: When using collections of data, remember to specify the dimensionality of the input and output of the component that the data is going in. When you want to create a split component, make sure to change the dimension of the output to 1-D rather than 0-D.
  • Data
    • Definitions: Define data types before working on component types, because in order to define components you need data types to specify the inputs and outputs.

  1. Manage Data -- add datatypes, upload data, add metadata properties
  2. Manage Components Types -- add categories for components, add abstract component types
  3. Manage Components -- add components, upload component code
  4. Edit Workflows -- create workflow templates
  5. Manage Domain -- set working domain, change execution engine, import system domains

As a Workflow developer, you can take advantage of these unique features of Wings:

  1. Getting Wings to Automatically Select Workflow Components
  2. Getting Wings to Automatically Generate Metadata
  3. Creating Valid Workflow Templates
  4. Interleaving Execution and Planning

Here is a Video to create and run a sample Text Analytics Workflow:

To use the ''Wings Portal'', you would need to:

As an additional aid for workflow developers, we have developed the Basic Component Encapsulation (BCE) methodology for creating workflow components. It helps avoid simple modeling errors, but it is not a requirement for Wings. There is detailed documentation and Example BCE Compatible Scripts
