Rod,
Creating new identifiers is exactly what PESI has NOT done!
It has re-used the identifiers from it’s source databases: Fauna Europaea, ERMS/WoRMS & Index Fungorum.
I think the same is true for EU-BON’s taxonomic backbone as they uses PESI.
So maybe we should reformulate the question and ask why GBIF is adding to the identifier soup… :)
Anyway, about the initial question: PESI vs GBIF identifiers.
We have used the short version what you describe: we don’t even need to call the GBIF API to generate the links:
Same example for Prionus Geoffroy, 1762:
http://www.eu-nomen.eu/portal/taxon.php?GUID=urn:lsid:faunaeur.org:taxname:115091
http://data.gbif.org/species/ + [Fauna Europaea species identifier=115091] + /resource/ [GBIF dataset id for FE=13560]
=>
http://data.gbif.org/species/115091/resource/13560
And there is the GBIF link, without calling any API.

And while we’re at it, will someone please explain why every biodiversity informatics project seems to feel that it is essential that it produces its own identifiers, independently of whatever has gone before. Simply contributing to the identifier soup is not helpful.

Dear Anton and colleagues
Might it be possible to pick this issue regarding the taxonomic backbone up, since this concerns EU-BON? I think this is an important issue to assure that GBIF/EU-BON’s names are mapped.
The PESI web site links names to GBIF, so PESI has a mapping between their LSIDs and GBIF. One way to go from a PESI LSID to GBIF would be if PESI provided that mapping in their web services http://www.eu-nomen.eu/portal/webservices.php It’s not clear to me that they do this.
Alternatively, Fauna Europaea has been indexed by GBIF (more than once!), so you could use the GBIF API like this:
1. Given a LSID like urn:lsid:faunaeur.org:taxname:115091, trim off the “urn:lsid:faunaeur.org:taxname:” to leave “115091”
{"offset":0,"limit":20,"endOfRecords":true,"results":[{"key":103283278,"nubKey":1097026,"taxonID":"115091","genus":"Prionus","genusKey":103283278,"datasetKey":"90d9e8a6-0ce1-472d-b682-3451095dbc5a","parentKey":103294043,"parent":"Prioninae","scientificName":"Prionus Geoffroy, 1762","canonicalName":"Prionus","authorship":"Geoffroy, 1762","nameType":"WELLFORMED","rank":"GENUS","origin":"SOURCE","taxonomicStatus":"ACCEPTED","nomenclaturalStatus":[],"numDescendants":6,"references":"http://www.faunaeur.org/full_results.php?id=115091","modified":"2014-06-14T21:04:19.241+0000","lastInterpreted":"2014-11-03T15:22:26.302+0000","issues":[],"synonym":false}]}
The “nubKey” field has the value 1097026, which is the identifier for GBIF’s classification http://www.gbif.org/species/1097026 You can use 1097026 as the key in a query to get the distribution using the GBIF API.
Can you please join and use the GBIF API mailing list for questions relating to the API?
We don’t make explicit use of LSIDs on GBIF.org. I expect what you want to do is lookup the GBIF species key using the species API, and then use that on the occurrence API to get occurrences.
E.g. Given the plant genus Oenanthe you can look up the taxon (name usage) information using:
noting the usageID is 3034893 in the response. You’d presumably either do this on demand or map this to your own backbone periodically. This can then be used to search for occurrences:
Alternatively, if you were to publish your own checklist and have GBIF index it, the taxa would be searchable using your own sourceId:
Best for you to answer Antonio.
We found some problems using the GBIF API to search for occurrences and datasets. I will explain the use scenario:
Using the EU BON taxonomic backbone we will find out the LSID of a given species. Therefore, we want to use this LSID, a universal identifier actually, to ask for datasets and occurrences to each data provider. Using GBIF occurrence API we can search filtering by scientific name or even by taxonKey, but it seems that we can not filter using the LSID.
Is there a way to filter using species LSIDs or even translating these LSIDs to taxonKeys?
