Re: [myexperiment-hackers] FogBugz (Case 986) Inbox - myExperiment feedback from Jerzyo (address@hidden)

To Jerzy Orlowski,

You can get at all the components for WorkflowVersion 8 with the URL 
http://rdf.myexperiment.org/WorkflowVersion/8/Components.  This is due to 
how the RDF data is generated.  Most of the RDF is generated from database 
calls but getting the components requires a web service that returns all 
the components.  I have been mulling over a way to allow the URIs to 
resolve to the RDF data for each component individually and now believe I 
have a solution.

In answer to your other questions:

The best way to get all workflows of a particular variety is to use the 
SPARQL endpoint (http://rdf.myexperiment.org/sparql) and do the following 
query:

PREFIX dcterms: <http://purl.org/dc/terms/>
select distinct ?workflow ?thetype where {?workflow dcterms:type ?thetype . 
FILTER (REGEX(?thetype,'workflow_type'))}

Replacing workflow_type with application/vnd.taverna.scufl\\\+xml for 
Taverna 1 workflows and taverna2beta for Taverna 2 workflows.

You cannot currently get download (or viewing) statistics.  I have been 
thinking of exposing these figures but we have been in the process of the 
rationalizing them so they do not include hits from bots and spiders.  I 
think this rationalization process has occurred so I will add these to the 
RDF.  Workflows have a dcterms:created property, this is when the first 
version of the workflow was uploaded.  To find the the upload date of the 
current version of the workflow you need to look at the dcterms:created 
date for that WorkflowVersion.

Regards

David Newman
