After parsing the information from last week's SharePoint Conference 2009, I've come up with a list of SharePoint 2010 features and enhancements that might make it worth considering an upgrade. Some of these features are in SharePoint 2007 but have been improved in 2010, like the concept of content types. Some of these features are new, like tagging and rating.
Administration
- Services a la carte via Service Applications; Can build your own
- Performance enhancements
- Throttling
- Tens of millions of documents per library
- Multi-tenacy - Keep content separated via application level security
- Claims (SAML) based communication - sort of like Kerberos for external authentication
User Experience and Content Management
- Managed Metadata Service
- Enterprise Content Types
- Tagging and Rating (Taxonomy & Folksonomy)
- Content Organizer (routes content based on pre-set policies)
- Records Management (in place or upload to record center)
- Delete, Hold in-place, Archive with Link options
- Social features, social search, social bookmarking, search for user content
- My Sites: Customizable My Site templates, org chart, user's activity feed
- User Profile Service; Sync data from multiple sources into SharePoint profile
- Unique document IDs
- Visual Upgrade from 2007 sites - gradual or immediate
- Cross-browser support (IE 7+, Firefox, Safari)
- Improved mobile support
- SharePoint Workspace for offline collaboration
- ...and Office online applications
Development
- SharePoint Designer as a respectable development platform
- Visual Studio templates for SharePoint development
- InfoPath and Visio development of web forms and workflow (along with SharePoint Designer)
I plan to post more detailed blog posts on certain topics as time permits. For now this should give you a taste of what's coming in the new SharePoint.
