STASIS is anticipated to deliver a set of services that will enable businesses to interact with each other at the semantic level. These services will be made up of the following components.

A Beacon is the foundation of the STASIS system. It combines P2P and repository technology and can be deployed in any organisation wishing to use the system. Its purpose is to hold and share the semantically tagged information.

STASIS Beacons will operate in a federated manner as a STASIS Flock. This will allow unknown or uncertain semantic relationships to use the knowledge in all Beacons to help build semantic pathways.

The STASIS Semantic Analysis Tool is used to insert specifications that a company wishes to share on the STASIS network.

The user enters these specifications into the tool (Figure 1, step 1). The information is analysed based on user (e.g. internal to an organisation), sector (e.g. pointers to sectoral standards like RosettaNet) and global knowledge (e.g. ISO and UN code lists), as well as knowledge in the STASIS Flock (Figure 1, step 2). This new annotated specification, the STASIS Record, is then placed into the Flock via a Beacon in a neutral format allowing all others to process and understand it (Figure 1, step 3).

The STASIS Comparator will be utilised once a partner has a STASIS record and primarily when encountering a partner with another record. Both records are compared to search for matches (Figure 2, step 1). The user is prompted about any unclear results to assist in resolving them (Figure 2, step 2). This then creates semantic relationships on which the company can configure their mapping environment.

The STASIS Viewer will allow any party to browse the STASIS network to examine particular semantic structures and how they are being used. This is particularly useful when building new content such as messages or interface definitions. Existing strategies and definitions can be taken advantage of and in turn will bring the user benefit since these semantics are already part of the network making a company easier to establish a relationship with.

It is feasible that over time there will be conflicting information held within the Flock. The final application of the system is the STASIS Distributed Information Purifier. This application will clean the data and relationships ensuring that the system is operating efficiently.
