I support this proposal. To several people’s point on default – I agree with the proposal that ‘is_executable’ default to false. Getting into the subjective ‘which will occur more’ is both futurecasting as well as perspective. I do agree that, for the use cases I foresee, templates are the most likely playbook to be shared across org boundaries and between systems. But I think ‘false’ should be the default even if people think ‘executable’ playbooks are the more common case. -- Duncan Sparrell sFractal Consulting iPhone, iTypo, iApologize I welcome VSRE emails.

I think the majority will honestly be templates. So something like is_executable is probably correct and a default of false is probably good.

I assume this property would be required (?) and therefore we should decide what the default value (false) would indicate. I suggest that the default value should be the likely majority playbook class/category. So if most playbooks will be templates then is_executable would be a good name and default to false. If most playbooks would be executable then is_template might be better to name the property and that way the default value of false would work nicely.

Some of the important points: The difference between an executable playbook and a playbook template is mostly subjective. There are suggestions to the text to help clarify this. There is no difference between an executable playbook and a playbook template in terms of their properties The term paybook class is confusing, since it is specified using the type property of a playbook. A suggested proposal is to remove the concept of playbook classes, and replace it by a new Boolean property, maybe called “is_executable”, to differentiate between executable playbooks and playbook templates.
