Re: [cacao] Playbook Types
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.

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

Rich et al - I’m supportive of this change provided the proposed text to explain the template concept vs executable is updated to describe the use of this new property.

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.

Hi All,

On the working call yesterday there was a discussion about section 1.3 of the CACAO working document.  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.
