The Ω-RIDL language provides some syntactic sugar to do this. Combining mandatory and unique results in stating that there should be exactly one instance for the path. For example:

Delivery contains at exactly one Good.
Another form of syntactic sugar puts a uniqueness constraint on both reading directions and a mandatory constraint from left to right:

Product is with exactly one unique ID.
This constraint is typically used for identifiers]]> Tue, 21 Jul 2009 22:00:00 +0200 http://support.collibra.com/knowledgebase/article/AA-00133 Committing your application means explicating its semantics using the lexons in a pattern. It is a three-part specification where you:
Select the relevant lexons that represent the universe of discourse of your application.Constrain the use of the lexons representing the rules in your application as closely as possible.Map the conceptual paths that are constructed by the lexons onto paths using a query language understood by your application.Once you have committed your application it can unambiguously co]]> Tue, 21 Jul 2009 22:00:00 +0200 http://support.collibra.com/knowledgebase/article/AA-00130




While you are building a pattern, you create lexons. A lexon
consist of two terms with a connecting relation (role and corole). Each term
exists within a certain context, usually the location from which this
term is extracted (a document, web-page, schema, ...). This is what we
call the lexical level of the pattern. However, it is important to be
able to link these terms to the conceptual level as well, through concept
definitions.

patterns in your workspace.
You can select which kinds of
resources you want to find, be it Conceptual Patterns or
Terms. Resources can dragged and dropped from the search view to other view or
editors. For example, to add a term or lexon to a pattern, simply drag
it to the pattern that is currently open in the Visual Editor. Th]]> Thu, 16 Jul 2009 10:28:44 +0200 http://support.collibra.com/knowledgebase/article/AA-00108




There are two ways to alter a relations role and corole. 

The first way is by double clicking on the role or corole box (not the
label) and give it a new name when the input field appears.

The second way it is done is by switching tabs at the bottom of the Visual Editor to the Table Editor.

In the Table Editor, go to the lexon which relation you want to alter.

Click on either the role or corole to edit them respectively.

Press the TAB or ENTER-key to accept changes and apply t]]> Thu, 09 Jul 2009 22:00:00 +0200 http://support.collibra.com/knowledgebase/article/AA-00106







At the top of the Visual Editor you will find an icon toolbar which contains the 'Add Relation' icon (). When you click on this icon, a new dialog will appear. The terms that were selected prior to this action will be used to automatically fill this form. Another option to get to this dialog is to right click on a term in the editor and select 'New Relation'.



Fill in the role and corole of the relation (with/of in this example) and press OK. This will add a relation between both t]]> Thu, 09 Jul 2009 22:00:00 +0200 http://support.collibra.com/knowledgebase/article/AA-00110



There are two ways for removing a relation:
Using the Visual EditorUsing the Table Editor
1. Visual Editor
Click on the relation's connection and press RMB.

Select Delete Relation: ...

2. Table Editor
Go to the Table Editor by selecting the other tab at the bottom of the Visual Editor.

Delete the relation by clicking once on the X icon in the right column.
