[tdwg-content] Latest DwC as TAPIR output model?

Tim,
I think we will use TapirLink for now in which case we need to have the Simple Darwin Core schema implemented in TapirLink.
Any volunteers for doing that?

We will be interested in the IPT version at RC5.

Ta
Paul

You could evaluate the IPT for this yes.

There will shortly be a release of the IPT (the RC4 release which will
be available for first testing next week) which will have some
enhancements and bug fixes and I would recommend waiting for this
before evaluating.  The IPT has a TAPIR interface, although I am not
sure how much it has been tested in live deployments, as GBIF use the
DarwinCore Archive interface to harvest content as it is far quicker.
In addition GBIF, have initiated a major refactoring of the IPT to
address the feedback received in the first year of it's use.
Specifically, users have requested that it be lightened up
significantly (e.g. server requirements), made easier to install and
configure, improve performance and address the intuitiveness of some
of the pages on the user interface relating to the publication state
and the registration.  We are starting a 4 week coding camp on this
tomorrow, and I anticipate testing of certain components to begin
towards the end of September, known as a "pre-RC5 testing phase".
This will not be a complete IPT and we will canvass the community to
determine how much functionality should be supported by the IPT for
RC5.  This means there is potential that the IPT will not support
TAPIR but only the DarwinCore-Archive output format.  Following RC5 we
will only address bugs and halt new functionality additions until the
IPT is considered fully stable and considered to be at a General
Availability state.

If you have experience using, and are happy with TAPIRLink and the
operation of your TAPIR network then TAPIRLink would likely be the
best product to use for the time being, and you might consider
evaluating the IPT either at RC4, or get involved around the time RC5
components are available for testing.  What the IPT provides:
- the publishing of checklist and occurrence information from either
SQL sources or CSV, tab file (etc) upload
- the ability to author dataset metadata documents to accompany the
data, or where the dataset is not digitally available (e.g.
documenting undigitised collections)
- browse a web application in the IPT for each dataset
- register with GBIF associating the dataset with the Institutions of
interest (the physical owners and the virtual hosting institutes)
- Fast full dataset transfer: due to the DarwinCore-Archive output
format, it becomes trivial to transfer an entire dataset in a single
object
- Support "many to one" extensions to the core records (occurrence or
taxon).  Extension definitions may be registered for others to use.

I hope this helps guide your decision.  Please let me know if I can
provide more information on the IPT.

Cheers,
Tim
