There is a SOAP API available for dataload, allowing you to use a SOAP
library to communicate with the Search Appliance. For an overview of
SOAP, Please see the SOAP API
(here).
The WSDLs for the dataload API can be found on the Profile Tools
page. Providing these WSDLs to whatever tool your language uses,
such as Visual Studio's wsdl.exe program, should generate the
necessary wrapper class.
The parameters are defined within the WSDL itself, and are generally
the same as mentioned above in the Submission Format and
Reply Formats, with a few exceptions:
The entire transactions are wrapped by SOAP envelops and the
top-level elements are called dataload and
dataloadResponse instead of
ThunderstoneReplicationResult, respectively.
The dataload element contains a profile element in
addition to all the Items.
C# Example Project
A C# example project is available that demonstrates using both the
search and dataload SOAP interfaces.
In the System →
Advanced Tools section of the administration interface, choose
Extra Downloads, and then Thunderstone Soap Example. Instructions
are listed on that page and within the zip itself for how to use the project.
