SMWCon Fall 2013/Effective metadata management of sensor networks using SMW

At KNMI, metadata of observations from the KNMI sensor network is stored in several information systems that are only loosely linked. The collection of provenance metadata by scientists is therefore time-consuming and poses a risk to correct interpretation of observations. Also engineers and inspectors maintaining the network need to access many systems for information and have to keep the (duplicated) information consistent. This can be laborious and poses a risk to data integrity of sensor network information. To provide better access to metadata for provenance of observations and to manage this metadata more effectively, the need for a collaborative metadata management system has been expressed. To meet this need, a project has been started and have selected Semantic Mediawiki (SWM)as platform to establish a collaborative metadata management system at KNMI. At the SWMCon, I will present the steps taken and lessons learned towards this SMW based metadata management for sensor networks at KNMI.
