|Definitionskos:definition||This Engineering Report (ER) has been produced in conjunction with two other engineering reports from the OGC Testbed 13, the Abstract Data Quality ER  and the Data Quality Specification ER  to capture status quo, discussions, and results in the context of requirements for data quality assessment for Quality of Service in the Aviation Domain. It will, in particular, provide a Data Quality Assessment Service Specification. Much of the ER is presented in the future tense, using terms such as 'shall', in order to express requirements and constraints on future Data Quality Assessment Service implementations. The service specification includes design patterns, extension mechanisms, and service interface considerations.In recent years, the concept of data quality has generated a notable interest among System Wide Information Management (SWIM)  implementers, both organization-specific and global. In the context of SWIM and Service Oriented Architecture (SOA) implementations in general data quality pertains to two major use cases, service advertising and service validation:Service advertisinga service makes known to a potential consumer the quality of the data provided by the service. Based on this information, the consumer can determine whether or not the service meets its needs.Service validationassurance is given that the quality of the data provided by a service is consistent with the quality that is explicitly defined in a service contract or any kind of agreement that may exist between a service provider and service consumer.Both use cases share two common preconditions:An unambiguous definition of the concept of data quality exists.A set of measurable parameters that allow specifying data quality is defined.These are tasks that were performed as part of Testbed 13. The findings of the tasks are documented in the Abstract Data Quality ER (FA001) and the Data Quality Specification ER (FA002).|
