RE: Issues with XML and Semantic Web ?
There are problems with that scenario. Cross-jurisdictional queries are often not enabled by treaty and law. NCIC queries that reach into Canada, for example, can return hits but they cannot be acted on in most cases. So again, there are names and then there are semantics and operations. It is the context (the event types) that often determine the allowable operations. It is necessary to be very clear about this. Otherwise, consultancy leads to RFPs to which vendors cannot respond and agencies cannot procure. The so called 'federated query' is a source of many issues some of which the Markle Foundation pointed out. Even within the CONUS jurisdictions, the problems of crossing private/public boundaries with querying is always to be suspect and held to much higher auditing standards if the querying agency is a law enforcement agency. Otherwise, it is impossible to protect civil liberties. So it becomes a matter of associating the semantics of the ontology to the business rules based on event types (an ontology). This is one approach to the problem of acquiring identity without opt-in as is the case for sensor webs capable of using biometric properties to acquire identity and issue queries. len From: Chiusano Joseph [mailto:chiusano_joseph@b...] In addition to identifying opportunities for information sharing, these artifacts can also identify opportunities for federated queries (perhaps using Enterprise Information Integration - EII). Consider a hypothetical situation in which 2 agencies have arrest information for an individual - but one has it on a domestic basis, and another on an international basis. A federated query between these two data sources - which can be determined by comparing their ontologies and taxonomies - can yield an arrest record for a given individual on an international basis. I have found that in educating unfamiliar folks on these artifacts, it works best to use examples within their own domain. Familiary with their own data and concepts greatly eases the mental transition.
