First, make sure the section you want to add data for is available. To change the sections, edit the data structure.
Add objects to section
When creating links by adding objects to sections, there are two workflows:
If you've already added all program items, persons, topics, institutions, etc., but have not linked them yet, you can click Add existing. A new field appears, in which you can either start typing the name of the object (program items, posters, institutions, persons, places), or select the object from a dropdown (classifiers).
If you haven't added all data yet, you can add it directly from the section. Click Create new and select or enter the data of the new object. The new object will automatically get the right type, based on the section it is created in.
Relations between objects are bi-directional and can be created in two ways. You can for example assign a topic to a presentation by:
Adding the topic in the section Topics on the related presentation details page
Adding the presentation in the section Presentation on the related topic detail page.
When creating the relation in one way, the other way is also automatically linked and a section for it will appear in the objects of that type. If you don't want to display the 'inverse' section in the app, you can mark it as hidden.
Move objects in sections
If there are multiple options in a section, you can drag them in the right order with the arrows on the left.
Delete objects from sections
To delete an object from a section, click the trashcan. If you've accidentally deleted it, you can always get it back by adding it again: the object itself is not deleted, just the link.
Lock individual objects and complete sections
Individual objects can be locked by clicking the lock icon in the row. All items in a section can be locked by clicking the lock icon in the header. Locking is particularly useful when you work with (automated) data import: it prevents the locked items from being deleted or updated.
