Metadata seems to be used frequently to describe a SharePoint list’s structure. That structure allows the storage of data at the list item level.
How can I specify information about the list itself without relying on an additional column?
Ideally I want something like SPList.Properties [“Mykey”] = “MyValue”
PropertiesXml isn’t settable but is there any way to alter the data it returns?
There is no property bag on the SPList object itself, however you can use the one on SPList.RootFolder. Its SPFolder object has a Properties property.
