Navigating the catalogThe dataset catalog of MOTC portal is accessible from the front office for all users.21On the left side (1), are displayed: the number of available datasets,a catalog sort option to change the order of the datasets,a variety of catalog filters to find specific datasets,different possibilities to download the catalog.On the right side (2), are displayed the datasets. Each dataset is represented by a rectangle calleda “catalog card”. On each card, the dataset’s main metadata are displayed, along with quick linksto visualize the data.Sorting the catalogBy default, a dataset catalog is sorted by last modification date (i.e. the most recently modifieddatasets are displayed in first position, at the top of the catalog).It is possible to change in which order the catalog cards are displayed with the catalog sortingoption below the number of datasets, on the left side of the interface.4

The catalog can be sorted by a total of 10 methods. These methods are based on 5 sortingcriterias, each being available in both increasing and decreasing order. Dataset title: to sort the datasets in alphabetical order or reverse alphabetical orderModification date: to sort the datasets by most recent or oldest modification dateNumber of records: to sort the datasets by biggest or fewest number of recordsNumber of downloads: to sort the datasets by biggest or fewest number of downloadsPop

metadata. These filters should be used to filter the datasets by view (visualizations such as Analyze, Map, Calendar etc.), date, publisher, keyword, theme, language, and any other metadata available as filter category. When searching with the selectable filters, the platform will
