Content is king. Context is queen. Together, they rule the web. To make it as simple as possible for users to find the desired content on web sites, typically "related content" is shown in the context of a given topic or page. As a result context dependent information, e.g. related products, responsible contacts, further news, related links and assigned downloads can be better found by visitors.
With Microsoft SharePoint Server 2010 and 2013 managed metadata enables editors to define relationships between SharePoint items, documents, pages and users by simply categorizing or tagging it using centrally managed enterprise taxonomies. Content classification also provides a very flexible way to automatically display related content via search.
Compared to manual linking it makes it as easy as possible for editors to provide consistent context automatically at any time and to keep it current. For visitors the related content can quickly be found. In this way related content can save both, time and money.
Fig.: Sample implementation of the "Related Content Web Part" at this page. The content that is shown on the right hand side is linked automatically using tags / categories of the main page.
The Web Part is a new type of SharePoint applications, so called "search-driven" applications, that uses the advanced search features of Microsoft SharePoint 2010 and 2013 for content organization and presentation. It simply adds "Content Relationship Management" as known from Amazon.com to your SharePoint-based portal.
