from the BioCASE side I can add the following:

BioCASE is a European project and its also the name of the protocol (sometimes written as BioCASe).
The BioCASE portal (software) is referred to simply as the BioCASE portal.
The core of the BioCASE provider software (BPS) is called PyWrapper. This wrapper understands the BioCASE protocol, but also the Species2000/SPICE protocol. So you can use it to serve data in ABCD, SPICE/Species2000, DarwinCore, MCPDH, NaturalCollectionMetadata (NCD) or nearly any other XML standard with some limitations (unfortunately used by SDD).

TAPIR refers only to the protocol. The primary goal of TAPIR is the unification of DiGIR and BioCASE, thus replacing them so that data providers and clients can access our data in the same way. 
There is a full TAPIR provider software available based on the PyWrapper which is called TAPIR PyWrapper. 
There is no TAPIR portal yet or any other client application for TAPIR.

In many discussions currently RDF is considered a better way to share our data. To fully go the RDF way we would have to migrate the TDWG XML schema standards to some sort of RDF schema or ontology. There is still a performance problem with RDF if used with millions of records (equivalent to maybe hundreds of millions of rdf statements). So I dont see RDF being used right now in full production, but its surely a promising way to go.

Personally I am a bit concerned we are about to split the community again - this time into TAPIR and RDF; but maybe thats how technological progress is made...

Much of the confusion has come about I guess because DiGIR 2 is actually a code name for a project that is building a data service application that supports pluggable protocols.  There is no official name for that application, and there is no release (yet).

So to try and help things a little:

DiGIR 2 is a data server application, not a protocol.  The application supports multiple protocols for accessing the data it serves including:

* DiGIR 1.5 (i.e. the current version of DiGIR)
* TAPIR (may not be a full implementation)
* WFS (OGC Web Feature Service)
* possibly SPARQL (an RDF query language)

DiGIR 2 data server is being developed because we do not yet feel that there is a single unifying protocol for our community, and that new protocols may emerge and then different versions of the protocols will be developed.  Having a single data service application that supports pluggable protocols will, we hope, significantly reduce the maintenance and configuration overhead of those interested in serving their data, since one the application is installed, we expect it to be a relatively trivial matter to add protocols or updates to existing protocols.

We will provide more information about the project as updates become available.
