Kepler

I reproduced the bug when i ran two tpc03 workflows.

I think the question is: How is it that these kars contain different workflows that have the same LSID? I think the idea is that's not supposed to be possible, and we shouldn't try to handle such a case (defeats the purpose of a unique id system).

I've spent some time trying to recreate two different workflows with the same LSID, and short of hacking one copy's moml by hand, thankfully I can't. I believe the LSID db keeps track of used LSIDs and their revision numbers, so two copies of the same workflow can 'co-evolve' with unique revision numbers.
Also if you delete the db, the next time you revise a workflow it gets a new LSID, and the original is put in the derived from list.
Another thing I tried was putting an EML 2 Dataset actor inside a composite, and then changing its parameters, to see if somehow these types of changes are getting swallowed. But this incremented the LSID revision as one would hope.

Hi, Derik:

Did you try the two version of kar files which are in the attachment? May they will be helpful.

Thanks,

The problem is that changes to an EML200DataSource instantiated from the Data panel does not increment the workflow's LSID.

So when you drag a Data search result onto the canvas, the actor has a null LSID. Changes to this LSID-less actor don't increment the container's LSID.
Was a plan ever devised for how this should work?

KeplerLSID format:
urn:lsid:<authority>:<namespace>:<object>:<revision>#<anchor>
(https://kepler-project.org/developers/teams/framework/kepler-life-science-identifiers-keplerlsid )

To assign a Data set result an LSID, I imagine we should utilize the metacat url and id. E.g.:
urn:lsid:http://knb.ecoinformatics.org/knb/metacat:knb-lter-kbs.49.13
Is there a better url to use? The authority is defined as "usually the URL of the web service that assigned the namespace".

When the Kepler user changes the actor in some way, this lsid is put in the referral list and a new lsid is assigned.

Except I guess no "http://" in the authority.

After discussion with the group the current plan is to, when dragging out an EML 2 Dataset actor from the Data pane, just assign the actor a new LSID, putting the EML 2 Dataset LSID in the referral list.

One downside of this is that 2 instantiations of the same Data search result actor will have different LSIDS, so future work may have some difficulty determining these are the same actor. But the actor's recordid parameter can be utilized to see which use the same package id.

Fixed at r28927-28.
You'll want to re-instantiate your EML 2 Dataset actors instantiated from a Data search result.
