What does data publishing mean in the context of GBIF?
Making your biodiversity dataset(s) publicly accessible and discoverable in a standardized format
Data publishing within GBIF means making your biodiversity dataset(s) publicly accessible in a standardized format (most of the time, Darwin Core), so that it can be discovered and reused by other people.
What is an IPT?
a tool that helps you publish your data to GBIF
a tool that helps you produce a Data paper
The IPT (Integrated Publishing Toolkit) is a Java-coded software that allows you to upload and publish data to GBIF. It is not to be used as a data management or data cleaning tool.
The IPT can also help you with the process of writing and submitting a data paper, thanks to the EML file it generates automatically when you fill in the metadata for your data resource.
Which Creative Commons licences and waivers are recommended by GBIF for data publication?
CC0, CC-BY and CC-BY-NC
The Creative Commons licences and waivers recommended to publish your dataset(s) to GBIF are CC0, CC-BY and CC-BY-NC. They are widely recognized licenses and/or waivers that align with international open-data requirements for data sharing and re-use.
Please note that you should only choose CC0 or CC-BY waiver/license for your BID-related dataset(s).
What are the three Cores from which you can choose for an IPT resource?
Occurrence Core, Taxon Core, Event Core
You can choose one of the three following Cores for each of your IPT resources: Occurrence, Taxon or Event Core.
The Darwin Core standard also allows you to link extensions to your chosen Core, such as SimpleMultimedia or MeasurementOrFact.
The metadata are filled in a separate section of the IPT and are shared using the EML standard, not the Darwin Core (which is used for data only).
How many Extensions files can a dataset have?
as many as needed
Once you have chosen a Core for your IPT resource, you can add Darwin core extensions to it. You can add only one or several extensions, depending on the type of Core you chose, and which extensions are compatible with it.
Extensions are not mandatory (you can publish a dataset without any extension) but can be useful if you want to share additional information that you could not map with your chosen Core.
