Abstract

WP5 of JERICO NEXT has the main objective of enabling free and open access to data having high quality accompanied by information that allow their easy use. This requires well defined architectures, policies, practices and procedures that properly manage the full data lifecycle needs of data producers and data users. In other words, in JERICO NEXT it is essential to assure the quality of data, control, protect, deliver and enhance the value of data and information assets. Quality control of data is an essential component of oceanographic data management. Data quality control information tells users of the data how it was gathered, how it was checked, processed, what algorithms have been used, what errors were found, and how the errors have been corrected or flagged. Without it data from different sources cannot be combined or re-used to gain the advantages of integration, synthesis, and the development of long time series. Information quality means consistently meeting the information customer’s expectations. Information quality means the degree to which information has content, form, and time dimensions which give it value to specific end users. Based on user requirements, ISO standards are providing the quality elements that define the extent to which data sets or data set series can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.
