Extract Policy Components (Specifically hardware devices) from SQL Database

I'm trying to find both where it's stored and how to extract the list of Hardware Devices (name and device IDs) from the database.

I may have narrowed it down to the BASIC_METADATA table, though I'm not sure.

I have found refereces to the names of the devices where the column 'TYPE' is "OpDevice", but I can't make heads or tails of the value in the 'Contents' field.

It appears to be encoded somehow, but the schema document only says for that field "The XML content of the schema object".

Anyone know how to get the actual values?  I need to export that to a spreadsheet.
