WS-VLAM Tutorial Part I: Hands on the User Graphical Interface Adam Belloum

Outline Part I: Hands on the User Graphical Interface Part II: Port a Legacy application to WS-VLAM Part III: Learn how to use WS-VLAM API

Outline (Part I): The user Graphical Interface Step 1: Start the WS-VLAM Step 2: Create Credential / Delegate credentials Step 3:Execute existing workflow Step 4:Monitor running workflow Step 3: Tools for semantic annotation, virtual file browser, repository, provenance

Step 1: Start the WS-VLAM workflow composer (GUI) As a webstart application – Go to : – Click on the button [ Try-it now ] Requirements: – Your web browser should be configured tostart “webstart application” – JAVA 1.6 need to be installed on yourdesktop/laptop

Step 1. Start the WS-VLAM GUI (1/3) First pop screen: asks for the application touse open WS-VLAM Webstart Application – Choose open – Click OK

Step 1. Start the WS-VLAM GUI (2/3) Click trust Second pop screen: asks you to Trust thesigned WS-VLAM Application

Step 1. Start the WS-VLAM GUI (3/3) Third pop screen: should WS-VLAM workflowcomposer The composer comes pre-loaded demoworkflow, that will be your WS-VLAM “ hello word ”

Step 2. Create/delegate Credentials (1/6) WS-VLAM workflow composer Canvas List of components Property window Monitoring window Action: Click on delegateCredentials Button

Step 2. Create/delegate Credentials (2/6) First popup screen: warning that you are going to send your credentials to aremote service Action: Click on yes

Step 2. Create/delegate Credentials (3/6) second popup screen: Create your proxy credentials window Action: Type in yourcredentialpassphrase Click Create

Step 2. Create/delegate Credentials (4/6) Third popup screen: proxy credentials created window On WS-VLAM composer bottom left corner you will adecreasing timer showing the time before your proxycredential expires Action: Click Ok

Step 2. Create/delegate Credentials (5/6) Option popup screen: If you push the option button in the proxy createwindow You get options proxy option window Action: Change thedefault time Location of theprivate and publickeys

Step 3. Execute workflow (1/1) Option popup screen: If you push the option button in the proxy createwindow You get options proxy option window Action: Change thedefault time Location of theprivate and publickeys

Step 4. monitor workflow (1/3) Monitoring popup window: Default Workflow components tabs Action: Select acomponent tab

Step 4. Monitor workflow (2/3) Component tab: Module status: shows the submission status of thecomponent: NOT SUBMITTERD ACTIVE REGISTERD DONE Action: Select Modulestatus tab

Step 4. Monitor workflow (3/3) Component tab: Std out/Std Err: show standard output/ Error Action: Select std Out tab
