Labeling Schemes

Labeling schemes determine how the label that identifies and represents a record is derived from the fields in the record. For example, person records label might comprise the surname together with the given name, while for vehicle records the label might comprise the manufacturer, model and registered number. You can also include 'free text' in the label, text that does not vary between labels.

About this task

For each item type in a labeling scheme, you can set the label to be used with iBase records, and the label to be used when records are converted to chart items.

Each labeling scheme covers all the entity and link types in the database. If there is more than one labeling scheme, it is because you might want different label formats at different times. You specify which scheme is in use by making it the 'default'.

Note: For certain entity types, Smart Matching in Analyst's Notebook assumes a property semantic type for the label value. Since the semantic type that is assumed cannot be changed, specify an entity type's label to be a property with a suitable semantic meaning. Consider that for some entity types, the assumed property semantic type is a Details kind. The label is then parsed during Smart Matching to locate the various parts of the textual value. Do not assign a Details kind of semantic type to a property that is used for a label. Instead, specify a property that is a part of a Details type, and assign the semantic type with the correct specific meaning. For example, for a Credit Card, specify the label to be the Card Number property, which is a part that is located in a Bank Card Details property. For more information, see the topic Assumed Semantic Types for Labels.

Procedure

To create a labeling scheme:

Select Format > Labeling Schemes > New.
Select the entity or link type to label.
Display the page for the type of label you want to define.
- Standard for the label to be used for iBase records.
- Chart for the label to be used for chart items.
Select fields and text you want to include in the label.

Note: You can see a Sample label. Click Next and Previous to change which record the sample is based on.
Repeat these steps until you have defined standard and chart labels for all the entity and link types as required.
If you have more than one labeling scheme, you must set one to be the default, that is the scheme that is in use at any particular time. To select a labeling scheme as the default: In the Database Explorer window, right-click on the labeling scheme and select Set as Default.
