The amount of digital data available to researchers and knowledge workers has grown tremendously in recent years. This is especially true in the geography domain. As the amount of data grows, problems of data relevance and information overload become more severe. The use of semantics has been proposed to combat these problems (Berners-Lee et al., 2001; Egenhofer, 2002). Semantics refer to the meaning of data rather than its syntax or structure. Systems which can understand and process data at a semantic level can achieve a higher level of automation, integration, and interoperability. Applications generally use semantic technology for three basic purposes: (1) semantic integration, (2) semantic search and contextual browsing, and (3) semantic analytics and knowledge discovery (Sheth & Ramakrishnan, 2003).

Situational Enterprise Services
The annotation of an object, relating its concepts to well defined semantics. This allows computer reasoning about the object. A simple example would be to provide a US zip code as a general zip code. On a higher level, the semantic annotation could express information about the functionality of the service.

Semantic Integration for Research Environments
is a piece of (structured or not) human-readable information (which can also be computer-readable) that (1) constitutes a metadata description of the annotation subject and (2) relates to the knowledge domain of the reality modeled by the system (Bechhofer, 2002).
