I am laying out some foundational work.

I came across two valid syntax of Historian Tag Path:

### short version:

`DB_GW_A01/gw_maker:default]wm01`

### long version:

`histprov:DB_GW_A01:/drv:gw_maker:default:/tag:wm01`

From your experience.  
Which one is more acceptable?

Presuming you meant to have a leading open square bracket on the first one, what you have are the formats for tag bindings in Vision versus Perspective, respectively. The scripting calls for history seem to accept both forms.

Thanks for the input.

If that is the case,  
My guts says, use the long version..

Just for the record.

-drv- means historian driver with syntax `<gateway_name>:<tagProvider>`

what does `"blank":"blank"` means?

`"this gateway":"default tag provider"`?
