Mélianie, if you use the IPT as a hosted service and not in a local network there are several things to consider:

a) it is unlikely that your system admin will open the database ports to the internet. Therefore you will only be able to upload text files into the IPT which you will need to export from the original provider database. The other option you have is to host a copy of the original database as it is in their original database system at GBIF france. This way the IPT can read locally from the DB. But it requires you to host a variety of systems and people to dump their entire database. I would think the ttext file approach is more likely - but maybe a mixed approach would work too.

b) in any case the IPT always reads in an entire dataset, even if only few records have changed. There are some technical and some usability reasons for this

c) the current IPT needs to be linked to a single organisation, so the resource metadata will always point to this single organisation. This is obviously not suited for hosting datasets from across the country. We plan to release a new version 1.1 at the end of march to address this, which is specifically targeted at an hosted environment.

Dear Tim, Andrea and Marcus,

I'm forwarding you a question from Delphine Gasc from GBIF France concerning the IPT. She has asked me to help translate the question so here goes:

GBIF France is planning to install a public IPT installation to test the scenario in which different users could connect their data via a central IPT installation. They are starting with a 'test' data provider who has asked them a question regarding database updates. If they have already connected their database to the central IPT installation and then update it, do they need to send the whole updated database to GBIF France (and GBIF France will then do the replacement) or should they just send the new data points (and then GBIF France should just add these)? What is accepted by the IPT?

Would any of you be able to help clarify this? Or point us in the right direction?

Thanks!

Mélianie

Bonjour Mélianie,

J'espère que le temps n'est pas trop mauvais à Copenhague. Le retour de Madagascar s'est bien passé?

J'ai une question concernant l'IPT, et je ne sais pas trop à qui la poser (ni comment la poser en anglais) donc je fais appel à toi.

Nous envisageons d'installer un IPT public au GBIF France afin de tester l'IPT en situation réelle pour connecter des bases françaises. Le fournisseur qui nous servira de test demande comment se passeront les mises à jour : devra-t-il nous renvoyer toute sa base mise à jour (et donc on fera du remplacement), ou bien simplement les nouveaux enregistrements (et on fera de l'ajout). Je ne sais pas ce qui est accepté par l'IPT.

Peux-tu te renseigner là-dessus pour moi s'il te plait?

Bonne fin de journée Delphine
