Hi Ariel, all, Ariel Oleksiak schrieb:
1. I understand that there might be several dependencies related to a single job. If so, you assume a conjunction or disjunction of dependencies? In other words, ALL dependencies or ANY of dependencies must be met (e.g. jobs finished) to start a job? In my opinion both cases are sensible and justified so it would be useful to enable determining it in this extension. However, dependencies would have to be probably grouped into groups concerning particular jobs.
yup, true. I just overlooked that, sorry. In our own, proprietary stuff, we handle this. I will incorporate the conjunction/disjunction notion into my proposal.
2. I understand that the condition 'before' means to start a job before other job has been started?
Yes. However, you are right that this is ambiguous. I agree that the best way to handle this would probably be to couple the condition to job states, but...
I think the most general way to express conditions is to allow specifying after which state of other job a given job must start (e.g. after start, finish, failed, canceled etc.). The problem is that as I remember well definitions of job states are not a part of the JSDL specification.
that is the problem. Alas, I don't see a solution for this. Any thoughts on this?
3. Have you considered passing output data from workflow jobs as input data to another jobs in JSDL? To make it independent from chosen nodes there should be a possibility to express input/output files as logical identifiers unique within a workflow.
Yes, I am currently working on this. My idea was to add an ID attribute to the <jsdl:DataStaging> element, which then could be referenced in other <jsdl:DataStaging> elements; I will put this together during the next days and then happily discuss the implications on the list.
