Hi Yan, the way you describe is the current way to go. IPNI unfortunately has 2 problems you should be aware of. The dataset in GBIF is a somewhat outdated and has not been updated since 2009. We are working with Kew to publish a new version for a long time, but things progress very slowly.
The other issue is that IPNI really is 3 datasets combined all of which can cover the same name. You should therefore be prepared to find multiple ids for the same name - even on their current website. See http://www.ipni.org/about_the_index.html For example Avena sativa gives 3 hits from IK, GCI & APNI: http://www.ipni.org/ipni/simplePlantNameSearch.do?find_wholeName=Avena+sativa&output_format=normal&query_type=by_query&back_page=query_ipni.html In the future we would like to add a scientificNameID property to the GBIF backbone taxa and populate that with IPNI, IF or ZooBank ids. But that is not available so far.

What?s the easiest way to do this? I can use the standard API, e.g. http://api.gbif.org/v1/species/2705290/related for 2705290 = Avena sativa, which gives me an output that contains several IPNIs (in this case, 164949-3, 391732-1, 27200-2, of which the number 391732-1 seems to be the canonical one, although I can?t figure out how to identify it as such from the GBIF API output) It will obviously be tedious (and unwarranted) to make 2 million API calls. What?s the recommended way to do this?
