SPARQL Endpoint

We have set up a SPARQL Endpoint to access the published workflows.

The SPAQRL Endpoint accepts queries written in SPARQL. For example, if you want to retrieve all the URIs of the published templates, you should copy and paste this query:

select distinct ?template where {
  ?template a <http://www.opmw.org/ontology/WorkflowTemplate>
}

If you want to retrieve all the executions of the templates you can use the following SPARQL query:

select distinct ?run where {
 ?run a <http://www.opmw.org/ontology/WorkflowExecutionAccount>
} 

The SPARQL Endpoint is available HERE

You will find more ellaborated examples here: http://www.opmw.org/node/6

Linked Data Application

We have developed a simple application to browse the published workflows. The application consumes the Linked Data exposed by the SPARQL endpoint, easing the task for the final user. The application has the following features:

Do you want to give it a try? Click here and write the name of the workflow you are looking for. If you don't know one, just press a letter (e.g., "a") and all the workflows with "a" on their name will appear in front of you to.
