Dear Juan,

Unfortunately we have no tool for creating these kind of SQL like queries to the portal. I am sure you are aware that the filters in the occurrence search pages can be applied in combination in numerous ways. The API can go even further in this regard[1], but it not well suited for retrieving occurrence records since there is a 200.000 records ceiling making it unfit for species exceeding this number.

There is going be updates to the pygbif package[2] in the near future that will enable you to launch user downloads programmatically where a whole list of different species can be used as a query parameter as well as adding polygons.[3]

In the meantime, Mauro’s suggestion is excellent. If you can narrow your search down until it returns a manageable download (say less than 100 million records), importing this into a database should be doable. From there, you can refine using SQL queries.

Best,

Jan K. Legind, GBIF Data manager

Subject: Re: [API-users] Is there any NEO4J or graph-based driver for this API ?

Hi,

One solution I have successfully adopted for this is to download the records (either "manually" via browser or, yet better, using a Python script using the fine pygbif library), storing them into a MySQL or SQLite database and then perform the relational queries. I can provide examples if you are interested.

Best regards,

Hola,

Is there any API for making relational queries like taxonomy, location or timestamp?

Thank you and best wishes

Juan
