Not 100% sure I understood your question, but will try to answer:
1. Native QVD read/write support is coming in Expressor v3.11 which is due out this quarter
2. Expressor allows users to define rules / expressions once and then re-use those across different data flows
3. User created artifacts (rules, schemas, composite types, etc) can be checked-in to Expressor's built-in version control and shared across projects
Hope that helps.
Hello Alex - please take a look at this document to see if it answers some of your questions:
Note that in release 3.11 (due out shortly this month) - QlikView QVD Read and Write Support will be available. This will enable you to use the QVE Desktop product, (allowing graphical design, storage, sharing and reusability) to populate your QVD layer, if applicable.
You would then use the QVD layer as you would normally with QlikView.
Please note that if writing to QVX, you can then leverage the QlikView Expressor connector in QlikView Desktop to access the data directly from the Dataflow.
Please take a look at this video for more information.
