I was going to point you to Teiid's thread on Dynamic VDB's, but you've already been there....
The VDB editing framework, which you are using in 7.0, is not currently exposed in any other way, but it could be. Designer 7.1 will contain additional programmatic logic to re-implement Preview Data functionality and it builds on the framework, but again, does not expose what you need.
Please enter a JIRA feature request including as much of your use-case as possible.

Thank you Barry for the helpful information. As I have requested in a different thread, what I have asked here would be addressed if Admin API's addVDB can be used to deploy dynamic VDB (except for ldap type as per my knowledge). I will wait for the confirmation on the other thread (https://community.jboss.org/message/552440#552440).Thanks,Abraham
