From the Options menu, choose Templates and Profiles. On the right of the page you will see the available CMDI profiles. You can select from the list or add new ones.
In order to add new profile, select the dialogue box Add URL and paste into it the URL of the profile you want to import. You can find the URL, for instance, in the Clarin website, under the Component Registry. Note that only published profiles appear by their name; otherwise, they are displayed in the list by their ID (something that starts with clarin.eu).
In order to import a profile, it needs first to be selected through the check box. Then, right clicking on the Local Corpus node open the Add menu. Here you will find the names or ID of the profiles that are selected in the list. Choose the one you need. It is now imported and it will appear in your Local Corpus.
