[tdwg-tapir] Tapir protocol - Harvest methods?

I guess you wanted something like a graphic representation showing the
number of providers/records using TAPIR versus the same with DiGIR over
the time. I also wanted to see this. The closest thing we can probably do
now is to query GBIF's UDDI registry. Today the figures are:

* 64 TAPIR providers.
* 190 DiGIR providers.
* 157 BioCASe providers.

But I have no idea about how this is changing over the time and I don't
know what happens when a registered DiGIR provider switches to TAPIR (if
the old record gets deleted in the registry or not). I also don't know if
all providers there are active, and we should certainly consider that not
all existing providers (DiGIR or TAPIR) are registered there.

I cannot tell about the other networks, but I know that the speciesLink
network is planning to migrate all local providers to TAPIR. Not sure when
exactly this is going to happen.

There are many ways you can harvest data from a TAPIR service. Markus
mentioned how GBIF is doing this. The easiest way is probably using
filterless search requests with TAPIR paging.
