Adding Metadata in SharePoint
Sometimes you want to store extra metadata in SharePoint for lets say a SharePoint web instance. Serge has a post about this topic; for a SharePoint web you can easily use the Properties property (so obvious, but I wasn't aware of this property!). But I have some doubts for the SharePoint List, Serge recommends to add an extra field. But this field would exist for each item in the list, a little bit overkill I think... :-)
