Rule-Based Querying of Distributed, Heterogeneous Data

Tom Lansdale, Peter Bloodsworth, Ashiq Anjum, Irfan Habib, Yasir Mehmood, Richard McClatchey
2009 IETE Technical Review  
Our work thus far has produced a prototype architecture for the querying of heterogeneous distributed data in the medical domain.  ...  A theme that is common to both this domain and the emerging Internet of things is that users often need to query more than a single resource.  ...  An architecture is presented, which facilitates the querying of heterogeneous, distributed data resources.  ...
