Integrating Semantic Technology with Legacy Databases

A study was conducted to find the optimal approach for integrating semantic technology across the extensive data banks utilized by the Laboratory for Laser Energetics (LLE). In addition to the immense amount of information stored by LLE, there are multiple repositories of data, making it difficult to locate and process information critical to the operations of the laser facilities. Semantic technology facilitates information processing by linking data and associated properties into an ontology model. The use of Java frameworks such as Jena and D2RQ was explored in order to allow this scattered data to be imported into a single ontology without duplicating the information.
