This guide gives basic instructions for starting and using the VARS knowledgebase interface. Useful definitions and descriptions can be found in the glossary. If you need extra help or information, see the Contacts section.
Start the program by double-clicking on the VARS knowledgebase icon. This logo will appear while the knowledgebase loads. After the knowledgebase finishes loading, the knowledgebase interface opens.
Do not use your network password as the VARS administrators can view the password you choose.
Browse features include:
Alternately, use the triangle icons to Expand and Collapse the selected node.
Edit features for the primary concept name include:
Add new concept name, or edit values including Parent, Author, ID Code, Rank Name, Rank Level, Reference. A concept name can also be selected for editing via the Edit Menu > Edit Selected Concepts.
Refresh – Reloads the latest data from the database.
Notes on editing concept names:
For internal users, please view our MBARI conventions for Search and Browse here.
Access the Names tab for the selected concept to add or edit the primary concept name and any alternate names.
Primary concept name and author can be updated by changing the appropriate fields and clicking the Update button.
Click New to add alternate names, types (e.g., common, synonym, former), and authors.
Notes about Names:
For internal users, please view our MBARI conventions for Names here.
Templates are a series of related fields that can be used to describe a Concept or object.
They are created once in the knowledgebase and can then be used repeatedly to: a) attach as a “static” property (also known as an attribute or link realization) to any concept name in the Knowledgebase, and b), attach an “instance” property to any real observation made during the creation of annotations.
Templates include the following fields:
Click New to open the dialog window for adding a new Template (Note: Search feature is disabled here as user expected to create a new, unique Template). To change an existing Template, select and edit the field and click Update.
Notes about Templates:
For internal users, please view our MBARI conventions for Templates here.
Properties are created from preexisting Templates.
As described above, Properties are added as a) “static” properties attached to, and always known to be true for, a specific concept in the Knowledgebase or b) as “instance” properties to unique observations made during the annotation process.
There are three types of Properties that can be created:
Click New to open the dialog window for adding a new Property. To change an existing Property, select and edit the field and click Update.
Notes about Properties:
For internal users, please view our MBARI conventions for Properties here.
Any type of media file can be linked to individual concepts in the Knowledgebase. Typically they would be the best representative imagery, e.g., for identification or illustration of particular features.
In the dialog window that appears, enter URL (location of image), Media Type (icon, image, video), Caption, Credit, and check box if it is the Primary image (e.g. best representative for identification).
Notes about Media:
For internal users, please view our MBARI conventions for Media here.
All Knowledgebase changes by all users are tracked in the History. As noted above, concepts with new edits appear red in the hierarchy until they are approved.
For each entry, the following parameters are viewable by all users: Created by and on which date, Approved (Rejected) by and on which date, Action, Field, and New and Old values.
Users with Administrator permission can approve additions, deletions, and edits to the Knowledgebase. To do so, select Reject or Accept each change using the buttons on the bottom right of the screen.
If a concept name(s) or properties are being deleted, additional dialog boxes will appear for the user to make a final confirmation.
If annotations that have been made using the Concept name(s) marked for removal still exist in the database, a final dialog will appear indicating the number of annotations that will be effected by the deletion. The options are to:
