Internet of Things devices and data sources areseeing increased use in various application areas. The pro-liferation of cheaper sensor hardware has allowed for widerscale data collection deployments. With increased numbers ofdeployed sensors and the use of heterogeneous sensor typesthere is increased scope for collecting erroneous, inaccurate orinconsistent data. This in turn may lead to inaccurate modelsbuilt from this data. It is important to evaluate this data asit is collected to determine its validity. This paper presents ananalysis of data quality as it is represented in Internet of Things(IoT) systems and some of the limitations of this representation. The paper discusses the use of trust as a heuristic to drive dataquality measurements. Trust is a well-established metric that hasbeen used to determine the validity of a piece or source of datain crowd sourced or other unreliable data collection techniques. The analysis extends to detail an appropriate framework forrepresenting data quality effectively within the big data modeland why a trust backed framework is important especially inheterogeneously sourced IoT data streams.
