Asio's query architecture enables users to search and discover cross-relational information from across the network. By starting with the Asio Semantic Query Decomposition (SQD) component and incorporating both the Asio Semantic Bridge for Relational Databases and the Asio Semantic Bridge for Web Services, the resulting query architecture enables users to search and discover cross-relational information from across the network.

The capability to mine information in a single vocabulary has powerful implications. Users are no longer required to dig through the intricacies of various data stores in order to retrieve the information they need. Data relationships and metadata previously understood by only a few operators can now be captured within the system through formal semantics, making them available for access by all users. Steep learning curves do not need to be repeatedly negotiated when new consumers are interested in a particular set of data.

Methodology

The purpose of the Asio Semantic Query Decomposition (SQD) module is to divide a SPARQL query, posed in this unified vocabulary (called the domain ontology), over multiple data sources. Asio SQD is a standalone component with open interfaces that utilize SPARQL. Each data source is represented with its own vocabulary (called the data source ontology) which Asio SQD uses to frame subqueries as decomposed from the original domain query. After creating optimized subqueries in terms of each data source ontology, Asio SQD takes the result sets of each subquery and transforms them into a single response using the domain ontology. It is this response that is returned to the user without exposing any of the particulars of any data store.
