Alternate Key in dsl.xml?

[ecruz]

We are using the latest Power Edition, and have a simple question (I hope): is there any way to specify an alternate key in a ds.xml file?

This is our use case: we are using BatchUploader to import records in a CSV where the DS is specified in a custom ds.xml (w/java server side code as well, for some custom validations/behavior). We want to ensure that there is no duplication in one of the fields immediately when the CSV file is uploaded. A primary key is already in place for other fields and that ensures no duplication in that context. An alternate key seems like a reasonable approach to do this, if supported. If there is any other approach that will work here, that would be fine also.

Thanks in advance.

In the BatchUploader case you can do whatever you want by targeting a .ds.xml that has custom Java logic to do translation of keys (or any other date) before saving to the actual target DataSource.
