Peter,

We are happy to hear that interest from species2000. The current version =
of the pywrapper that works with TAPIR and BioMOBY unfortunately doesn't =
implement SPICE at all. But I don't hink this will be hard to add (I =
will come back to it later). The previous version, pywrapper 1.x, that =
run with biocase supported SPICE. So I know pretty well how the =
specification works.

With TAPIR there are more powerful configurations possible, mainly =
through the use of "output models". Using this for SPICE will make it =
much easier to implement it. The only thing we would need is an up to =
date XML Schema. Then we will have to create a separate output model for =
each request-type - we could entirely reuse the SPICE schema.

Then there would need to be a small and newly developed "protocol" layer =
for SPICE in pywrapper. That also shouldn't be too bad. Overall I would =
expect something like 2 weeks for the implementation and another week =
for testing and configuring a database like the berlin model.

The only real problem with having a generic and configurable wrapper is =
that taxonomic data is build on tree hierarchies. This is often =
represented as self-references in databases but not always. SO inorder =
to "map" your local database to the SPICE schema it usually takes quite =
some transformation which you often have to do with views, cause generic =
wrappers like pywrapper cant handle this (you cannot simply add some =
custom SQL). So all I wanted to say here is that there still remains a =
bit of the complexity. But you can be sure the wrappers do understand =
SPICE correctly and respond properly - just the data they carry might =
not be making sense if they were badly configured.

Anyway. I would be very happy if we can make pywrapper SPICE compliant =
again. Unfortunately there is not much manpower left from Javier and =
myself this year, so we could only do little things. But we would be =
very happy to assist someone trying to get into the python code and do =
it himself. Its not that hard. Would that be a possibility?

With thanks,
Markus
