Information on the Didactalia Encyclopedia

The Didactalia encyclopedia is a tool that allows you to compare important events and characters in history with up to five layers of knowledge at the same time to facilitate global learning and learn more about the context you want to study.

Layer settings

You can configure the different layers to display from the icon of the lines, the second one located in the upper right part of the encyclopedia.

By default, the Historical Context and Science layers are displayed. The Historical Context layer is fixed and always remains at the bottom of the timeline.

You can select the layer or layers that you want to appear on your screen by clicking on the box to the left of each category. In addition, you can choose the order in which these layers will be displayed by dragging them with the icon to the right of each theme.

Within each layer you can choose the elements you want to show: either works, authors or both entities at the same time. In the case of the historical context layer, you can choose between rulers, historical events, political, or all.

The lifelines show the duration of the events. In the case of people, the life line ranges from their date of birth to their date of death, while a historical event ranges from the beginning of the event to its end.

Entity search

Write the name of what you want to find in the predictive search engine located at the top. You must enter a minimum of four characters for different search results to display. Then select the event you are interested in. By default, results will appear from all knowledge layers, even if they are not visible at the moment.

When selecting an entity that is not in a visible layer, the timeline will automatically remove those layers where the event is not found and will show the layers of the searched entity, in addition to the Historical Context layer.

Selected entities can be removed with the "X" button that appears in the search box. You will delete not only the search but also the layers that had appeared with it.

Center navigation

The center navigation button, which appears in the lower right part of the screen, allows you to return to the starting point of the search or selection of an entity, as long as it remains active.

Fix on timeline

At the top right of each timeline event there is a star-shaped symbol that you can click to set them. In this way, the fixed event will not disappear when modifying the timeline zoom and will always remain in the first line.

By clicking on the star icon again, the event will no longer be fixed.

It is possible to set several events at the same time.

Entity file

Double-clicking on the tab of an event in any of the layers shows the detailed information of the entity and a series of utilities:

- Information about the event extracted directly from Wikipedia with a link to said page so that you can expand the information displayed.

- Resources from the Didactalia repository related to the selected event.

- Videos about the chosen event available on Youtube.

- A conceptual map in the form of a dynamic graph with which to deepen the knowledge of the event.

Save timeline

The timeline automatically saves the information from the last session in the browser; that is, when exiting and re-entering the timeline, the last search performed will reappear, the layers that had been activated ...

The browser link collects the parameters of each search or configuration. In this way, this URL can be saved for later or sent to another device where it will be loaded with the same settings.
