The Tripal CV (Controlled Vocabularies) Module provides functionality for managing controlled vocabularies and the terms they are comprised of. The flexibility and extendibility of the chado schema depends on controlled vocabularies. For example, by using a controlled vocabulary for feature types the chado schema can describe features of any type, even those we have not concieved of yet.
After installation of the controlled vocabulary module, the following tasks should be performed:
Set Permissions: By default only the site administrator account has access to create, edit, delete or administer vocabularies and terms. Navigate to the and set the permissions under the 'tripal_cv' section as appropriate for your site. For a simple setup, allow anonymous users access to view content and create a special role for creating, editing and other administrative tasks.
Loading of Ontologies/Controlled Vocabularies: You can access this loader at Tripal Management->Tripal CV->Load Ontology With OBO File', 'admin/tripal/loaders/chado_vocabs/obo_loader') ?>. This loader allows you to choose from a list of common ontologies or enter the URL or location to an OBO file. Even the list of common ontologies is using a URL ensuring you get the most up to date ontology.
NOTE: in some cases, community developed ontologies for your data may not yet be developed. In this case, it is suggested that you begin developement of an ontology using one of the online tools. You might find that many researchers are trying to deal with the same data and are willing to help you in this endevor.
Aside from the data loading described above, the Tripal Controlled Vocabulary (CV) module also provides the following functionality:
Create/Update/Delete A Controlled Vocaulbulary: to create your own controlled vocabulary go to and fill out the form provided. To Update/Delete a controlled vocabulary go to , select the existing vocabulary you want to modify and then edit it as desired. This only modifies the vocabulary itself. See the next section for adding, removing, editing the terms of a vocabulary.
Create a Controlled Vocaulbulary Term: Use , select the controlled vocabulary you want to add terms to and then fill out the form.
