Frequently, I have information or a property that I want to share across all analyses in the library. These may contain expressions or variables to use for axis control, calculated columns, data limiting expressions etc. Rather than having to modify them individually in each of the many similar analyses we have, the ability to create and consume properties at the Library level would be very useful. Creation and control of these properties should require some sort of admin or author level access.
Thanks for an awesome idea Jeremy. It's related to this idea but also more capable: https://ideas.tibco.com/ideas/TS-I-6878
