Call minutes

Minutes from the ML Schema call May 23, 2016

Decisions:

• to add a link between Run and HyperParameterSetting to reflect that HyperParameterSetting is an input to Run (OpenML follows similar modeling) --> Issue #19
• to make optional that Task is "definedOn some evaluation specification"; instead reverse this relation and make a link from EvalutionSpecification to Task (e.g.: isAssociatedWith) --> Issue #20
• feature & data (issue #15): do no more than there is now and leave it as it is now
• to make optional that Run "has output some model evaluation"
• ML software (issue #18): yes, it is good to incorporate it; at the end we can simply add a class Software and use an external vocabulary / ontology (such as software ontology SWO or https://en.wikipedia.org/wiki/DOAP) to model whatever is needed such as a library name (scikit-learn, RapidMiner, ...), a version, a project name etc.
• use gh-page so it is more convenient to view the documentation
• to decide what to do further with the diagram
• to create an issue on whether (and how) we should model relations' domains and ranges
