Abstract

PURPOSE <br>This TReK requirements document has been organized with a specific implementation approach in mind based on the TReK project concept. A key part of the concept defines TReK as a COTS based system. Many requirements will be met by identifying a commercial product and by providing an interface to the product. Complete specifications for COTS products have not been developed. Instead, detailed capabilities provided through Enhanced HOSC System user applications will be used as the guideline for selecting commercial products. For example, a TReK user should assume that the commercial product selected to cover data display requirements will provide functionality similar to that found in the EHS Display Services applications. One should not assume that it will be possible to find a commercial product that provides an identical set of capabilities with regard to EHS applications. However, the goal is to match the functional capabilities as closely as possible. For these reasons, the TReK requirements document contains language such as "The TReK COTS product shall...". The intent is to identify within the TReK requirements document which requirements will be met with a commercial product.
