Alias for representations in TOC

I’m looking for some ideas on how to use an alias to describe features symbolized using representations in the TOC. The representation name in the TOC is not intuitive to the end user. This data will be used for a dynamic web service and the legend should better describe the data for the end user.

For example, change OBSTRN_A to display as Obstruction or LNDARE2_A to display as Land Area in the TOC.

The visual specification applied to the data was created for paper charting and has hundreds of symbols and representation rules. All of which look great with the exception of how the descriptions appear in the TOC. Is there an easy way (fingers crossed) to change the text that appears in the TOC or map service legend without updating the specification and symbol names?

We have four databases with the same schema and visual specification, each database represents a different scale of data. The changes to update the label in the TOC will need to be applied to all four datasets each with over 250 subtypes. The process will need to be repeatable.

I’m prepared to update the specification since the data will need to maintained over time and as a result the specification will need to be applied to update features. Before I take on this approach, I want to make sure there isn’t a better way to go about this. I’m open to any suggestions. Thanks.

Mapping Center Answer:

There is only one way to handle this issue, and it is actually before you create representations.  If you still have the layer you used to create the representations, you should edit the legend class labels; you can do that either in the TOC or in the Layer Properties dialog's Symbology tab.

Those values will be used as your representation class's labels instead of the actual data values.
