What is metadata in SharePoint?
Metadata enables users to quickly and easily classify specific data about documents and list items within SharePoint by using list columns.
Content types are a core organizational feature of SharePoint 2010. They are designed to give users the ability to organize SharePoint content in a centralized and meaningful manner. Site columns (metadata) can be encapsulated within a content type to allow for reusable structure or independently added to sites and lists.
At its most basic level, a content type is a collection of settings which can be applied to content. They are reusable since content types are independent of sites and lists. A content type includes site columns to define the desired information.
- Content types take metadata to the next level by providing a way to group a collection of metadata with a specific template.
- The Managed Metadata service offers a new way to look at content types and metadata. It allows you to provide a collection of metadata and content types to all sites within the SharePoint farm.
- With Managed Metadata Services, along with the Enterprise Term Stores, SharePoint administrators can configure a Content Type Hub
- Content Type Hub is responsible for managing content types that can be published to all site collections that are consuming the services provided in the managed metadata service.
- The Content Type Hub is configured once for each managed metadata service. Any site collection to which the Service Owner has access can be configured to be site collection hub.
New Managed Metadata Service Features:
- Column Types: Two new types of site columns can be configured at global level.
- Managed Metadata: You can create term stores that are used to populate various column types within SharePoint.
- Managed Keywords: Similar to managed metadata, with the key difference being that the end user is able to enter new terms into the store.
- Content Types: They allow for standard templates, metadata and workflows to be associated with different list items and document types.
- Metadata services in SharePoint 2010 are implemented through the use of a term store. Within the term store, groups are created. Groups are important because they are used primary as a security boundary. Term sets are the groupings that are used to organize the terms. At the lowest level there are terms, which are the values selected by users in the system.
- Group Properties: Once the group has been created there are tow levels of configurable permissions:
- Group Managers: Add items and assign other users.
- Contributors: Add and configure hierarchy.
- Term Set Properties: Properties can be divided into two areas.
- Ownership: You can configure Owner,Contract, Stakeholder.
- Usability: Submission Policy, Available for Tagging and Custom Sort Order
