Need help on designing downstream data sync with OLite

Question

We are trying to build a disconnected desktop application for CRM Sales Application.
For Data Synchronization, we would like to use TRS (Transaction Replay Service) for upstream sync (data from client to enterprise server).
For downstream sync (data from enterprise server to client machine), we would like to see whether we can make use of OLite data sync feature.
The client side db schema will be different from the server side db schema.
We have a web version application built using ADF framework (a list of BC4J objects).
We are going to create the client side db schema based on the shape of Sales View Objects.
e.g. an OpportunityVO (view object) is join based on opportunityEO (table) and customerEO (table to get the customer name). In this case, we are going to have opportunity table at the client side that has all the opportunityVO's attributes defines as table columns.
Questions
1. Can we define a publication item based on a view object? And how ?
2. Can we define a publication item based on a db view (at the server side) that
synch with a db table ( at the client side) ? If so, where do we set the mapping?
3. During the compose phase, we would like to call bc4j object’s api to collect the
data content for client to download, is it possible ? if so, how to do this?
(We would like to use the oLite feature to identify changed records, but we do
want to use bc4j object api to get the data content for client to download.)
Thanks

I haven't given your description of the project and approach a lot of thought yet, but I did see your questions and thought I might point out some help there:
1) Yes, you can define publication items on Views. Section 3.4.1.3.1 in the developer guide discusses this and the requirements of the view.
2) Yes, a publication item defines the base tables for your user. Section 3.4.1.3 in the developer guide is a full discussion on creating publication items programmatically.
Also, you might check into the Mobile Database Workbench for a GUI driven tool to define Publications and Publication Items.
3) I believe what you are looking for here is the MyCompose API. Section 3.6, Customize the compose phase using MyCompose, in the developer guide discusses this.
