Ifinally got around to reading thepreliminary info on MSDN in regards to how SharePoint 2010 will be treating taxonomy and metadata. As most of you know, MOSS2007 had some serious challenges in this regard that caused IAs like me much consternation when trying to implement effective content structures (e.g. no hierarchical metadata, no sharing controlled vocabularies across site collections, etc.).

It would appear that SharePoint 2010 includes many new features under the umbrella ofEnterprise Metadata Management to solve some of these issues. Here are the highlights…

1. Terms &Keywords

SharePoint 2010 has a few types of vocabularies with different levels of control:

Terms: Basic construct – a word or phrase that can be associated with content. A term can become a managed term or a managed keyword.

Managed Terms = A controlled term that can only be created by those with appropriate permissions.Term sets (can also be considered taxonomy facets) are collections of related terms that can be hierarchically structured.

Managed Keywords = User-generated keywords (aka tags) kept in a non-hierarchical list called thekeyword set.

What’s nice is that you can easily turn a managed keyword into a managed term, which essentially sets up SharePoint 2010 as a decent platform to blend taxonomy and folksonomy approaches (more on this later).
