Hi Roger,

The speciesLink network makes use of regional servers to mirror data from
collections that cannot set up a provider service. Some of them still use
dial-up connections for instance. The following diagram is not up-to-date
but gives an idea of how many collections are using this approach in the


We had to define our own protocol to achieve this. It's based on SOAP and
it has limitations such as only handling tabular data, but it does its
job. We developed a client software in Java which is installed on
providers' machines and has many interesting features. The newest ones
include automatic updates of the software, and the possiblity of choosing
mapping templates for specific collection management systems.

Best Regards,
