Re: [netmod] revised-datastores and commonality of schemas

[Kent Watsen <[e-mail]>]

Hi Jason,

All those details would need to be specified by some future templating drafts.  In this draft, there is only the provision for "configuration transformations" to keep that door open.

Hi guys,



Templates are something that may be problematic for this concept of common schemas across the running/candidate/intended DSes and then operational being a superset.



The <running> DS needs to have both the template itself in the schema as well as whatever nodes are used to hold 'exploded' data.  But what about intended and operational ?



For example, imagine we have the following instance data in a candidate & running DS:

1) a template that sets an admin-state leaf to 'enabled' in all interfaces

2) a set of 3 interfaces with a few leafs of config in them (address, etc)



Clearly the schema for the candidate/running DSes contain both the template and the interface schema nodes.



But does the schema for the intended DS actually have the template schema nodes ?   In theory it doesn't *need* to (since templates are exploded between running & intended), and it feels strange to have those in there, but I suppose it could have them.  If they are there, then a read of the intended would show "admin-state enabled" in the template *and* in the 3 interfaces.



Does the operational DS contain the template schema nodes ?  If yes, then I suppose we would consider all templates as 'applied' implicitly ?



Rgds,

Jason
