To benefit from the visualization and advanced analysis capabilities of other i2
applications, such as Analyst's Notebook, you can assign relevant data with a semantic type
that identifies the real-world content of the data.
About this task
There are two ways of assigning semantic types. You can either assign a single semantic type when
adding or editing entity types, link types, fields or standard fields by using the
Select Semantic Type For dialogs (as described below), or you can assign semantic
types to all the items in the database schema by using the Semantic Types dialog.
See Assigning Semantic Types to your data for more
information.
You must log on as a database administrator in order to assign semantic types.
Note: When you are assigning semantic types to fields, you cannot assign the same semantic type to
more than one field in the same entity or link type.
Note: You cannot unassign the semantic type of an item in this dialog. You can only assign a
different semantic type. To unassign a semantic type, use the Semantic Types
dialog. Select Tools
>
Database Design
>
Semantic Types.
Procedure
-
If this is the first time you have assigned semantic types in this database, you should load
the Semantic Type Library for your organization.
- Select an Entity Type, Link Type, Field, or Standard Field,
- In the Semantic Type area, open Select Semantic Type
For.
The Search Available Semantic Types box displays
the name of the current entity type, link type, or field. The Ordered Results area suggests some
semantic types that may be suitable for assigning to it, based on a comparison of its name with the
name of the semantic type and any synonyms set up for it. You can review the suggested semantic
types by clicking on a result to display information on the right.
- If none of the semantic types in the Ordered Results area are suitable, you can search
the library. There are two ways of doing this:
- In the Search Available Semantic Types box, enter the word or phrase
that you want to search on. As you type, possible matches are displayed in the Ordered Results
area.
- Browse the semantic types displayed in the tree view.
- When you have located the correct semantic type:
- Select it and click OK to return to the Entity Type, Link Type,
or Field dialog, which displays the selected semantic type.
-
Click OK to save your changes. The assignment is
not completed until you click OK. To cancel the
assignment, click Cancel.
