Learn how to create instances of built-in and user-defined classes

\n \n

Built-in classes (such as Container, Item, SELECT etc.) ship with system ontologies in LinkedDataHub while user-defined classes come from ontologies imported by the user (see the user guide on changing the model on how to do that).

Note that in order to create class instances, you have to be in properties mode.

Built-in classes

To create instances of built-in classes, follow these steps:

Click the Create dropdown on the bottom of the page
In the drop-down list that appears click on the menu item of the class you want to create an instance for. An editing form will open.
Fill out the fields in the form that appears. The mandatory properties are rendered in bold, without providing their values you will not be able to save the instance form.
Click Save
In case there were errors such as missing or malformed values, an error message will be shown and the offending property and value will be highlighted. Fix them or you will not be able to save the instance form.

You will be redirected to the document of the newly created instance.

User-defined classes

To create instances of user-defined classes, follow these steps:

Click the Create dropdown on the bottom of the page
Click on Instance in the drop-down list that appears. An editing form will open.
In the resource of Type Instance, click on the Instance typeahead input, type the class name and select the class from the list
Fill out the fields in the form that appears. The mandatory properties are rendered in bold, without providing their values you will not be able to save the instance form.
Click Save
In case there were errors such as missing or malformed values, an error message will be shown and the offending property and value will be highlighted. Fix them or you will not be able to save the instance form.

You will be redirected to the document of the newly created instance.

You can only create instances of classes that have constructors.
