It is anticipated that XML will heavily dominate the next generation of telemetry systems. The syntax of XML-based languages can be constrained by a schema that describes the structure of valid documents. However, the schemas cannot express all dependencies between XML elements and attributes, both within a single document and across multiple documents. This prohibits the XML validation process from being fully automated with standard schema processors. This paper presents an approach that is based on the W3C Semantic Web technologies and allows different vendors and system integrators to independently develop their own semantic validation rules. The rules are equipped with powerful semantics, which allows for specification and validation of complex types of constraints. The approach is not specific to a particular T&E standard and is entirely standards-based.

Development of intelligence products, especially when HUMINT and OSINT are involved, requires sifting through enormous amounts of (mainly unstructured) information. Although SMATs are a great way of achieving progress, most of the SMATs that have been evaluated by the Social Science Board (SSB) thus far have initially fallen in the"poor"and"weak"categories. Thus it is clear that tools that support the development and especially the use of SMATs are needed. VIStology will develop a tool that will take in information represented in RDF and produce visual output that is meaningful to the analyst, called concept map. The problem to be addressed in this research is the transformation of RDF to concept maps so that the resulting concept map is relevant to a specific analyst"s question, includes the appropriate context, and is presented in a more abstract form than the original RDF so that it is easy to comprehend.

In a competitive, dynamic, resource-scarce, and frequently hostile external environment as well as in a complex, diversified, and large internal system, it is increasingly important for organizations to react as quickly and precisely as possible to new and continuously growing challenges. Large organization and the government, in general, and the Department of Defense, in particular, are facing increasing levels of information sharing, exchange, and collaboration coupled with the necessity to maintain high levels of interoperability along with security, trust, integrity, efficiency, consistency, etc. Much progress has been made in recent years towards defining standards that enable improved information sharing and interoperability. New, especially XML based, standards (e.g. SOA) enable disparate systems to communicate with one another. These technologies also enable discovery of services through the use of metadata and related techniques. In this work we propose to take a further step and use ontologies (e.g. OWL based JC3IEDM) to provide semantically-sound techniques for better implementation of information management functions. This will provide the basis for a truly dynamic interoperability that will allow heterogeneous systems to reuse and leverage their capabilities without dramatic changes to their individual structures.

ABSTRACT: It is anticipated that XML will heavily dominate the next generation of telemetry systems. The syntax of XML-based languages can be constrained by a schema that describes the structure of valid documents and allowable values of attributes using data typing facilities. However, even on the syntactical level, the schemas cannot express all dependencies between XML elements and attributes, both within a single document and across multiple documents. This greatly complicates the validation process of XML data used in testing, because the process cannot be fully automated with standard schema processors. VIStology is proposing a solution that is based on Semantic Web technologies and allows different vendors and system integrators to independently develop their own semantic validation rules. Moreover, conflicts detected by the rules can be resolved with support of a solver. BENEFIT: (1) Different vendors and system integrators can independently specify their own validation rules. (2) The rules are equipped with powerful semantics, which allows for specification of constraints that any XML schema language could ever offer. (3) The approach is not specific to a particular T & E standard, it can be augmented to support validation of any XML-based standard. (4) The solution is entirely standards-based and thus should be cheaper for the government acquisition and maintenance.
