Sorry, don't understand what you are asking for ?
Knovel became a repository of an independent Mathcad English repository.
Knovel today may be another something.
From recollection, that Mathcad English repository started existing
in replacement of the former Mathsoft repository that disappeared
not long after Mathcad 8.
Are you suggesting Smath to access Knovel Metadata ?
...and Smath make a TOC of these Metadata ?
Accessing data between different CAS is very difficult
as there are so many data types ! The most ancient/universal *.dat.

Mind your SNR. A quick search for "Knovel" can shed (even official) light on the relation between SMath Studio and Knovel.

Thanks Mrtin,
At the time Knovel started collecting Mathcad work sheets, they were
recasting some work sheets from the Mathsoft Collaboratory.
Recasting but short of the Edu content.
At this time, Knovel didn't collect some of the most extraordinary Mathcad
from: Paul, Tom, Robert ...

Hard to visit ...

"For a long time our engineering department relied on Mathcad and the Mechanical Engineering Library addon, mainly for Roark's formulas. However, in our recent migration to Prime (for Windows 7-64 support) we thought we'd be able to get the same thing by subscribing to Knovel's Mathcad worksheets. However, it seems Knovel's subscriptions for Mathcad has been very recently been discontinued and they are no longer offering new subs (current subs are slated to be discontinued next year)... "
