I was able to figure out the necessary SQL. Sharing the below for any others looking to understand what is completely listed in the software portal.
SELECT
i.Guid [_itemGuid]
, i.Name
, i.Description
,CAST(CAST(State AS NVARCHAR(MAX)) AS XML).value(N'(//item/IsPublished)[1]','nvarchar(max)') [IsPublished]
,i.CreatedDate
,i.CreatedBy
FROM Item i
INNER JOIN ItemClass ic
ON i.Guid = ic.Guid
WHERE
ic.ClassGuid = 'E1C9F80B-5AC5-4970-8722-9E2BBB1E8147' --Altiris.SoftwarePortal.Resources.SoftwarePublishingItem
ORDER BY i.Name
