In reality, many different types of sites deal with content aggregation. Metaphoria, written in server-based Java, organizes references to data rather than the actual data itself. To accomplish this, Meta phoria includes tools that collect and build a repository of metadata links. This repository is then used to access and publish data as needed. Metaphoria's aggregation agents gather input from a variety of sources, including databases, XML documents, and HTML documents.
Syndication is the process of disseminating data.
On the Internet, syndication is often seen in the form of content that Web sites buy from third parties. For example, many Web portals incorporate news headlines as part of their home pages. This news content is generally syndicated from a news provider. In this scenario, the news service is the syndicator and the Web portal is the subscriber. StoryServer provides tools to define, extract, and publish syndicated content.
