The very nature of data is changing at a rapid pace. Data curation in hydrology has to be resilient to change so that data collected 100 years ago can be put into meaningful context alongside the data collected 100 years from now. There are too few people taking the long view of data management. Daily pressures for data production overwhelm our capacity to consider the future value of data produced today. This means that we need to pay close attention to the guidance offered by those who take the time to develop best practice approaches for hydrological data curation.
