Flexible nature of the current WICID system should allow for the addition of non-census datasets as long as the data is prepared in the required pair-wise origin, destination, variable format

• Flexible nature of the current WICID system should allow for the addition of non-census datasets as long as the data is prepared in the required pair-wise origin, destination, variable format

• Main challenges:

• Re-designing the interface to handle time-series data. Current data are discrete, cross-sectional data

• Some of the datasets (HES for example) present issues related to geographies: Currently, HES destination is a specific point, rather than an area

• Metadata redesign to clearly identify different datasets and characteristics for users

• Incorporation of ‘on-the-fly’ disclosure control routines for datasets like HESA
