About the IPT

The Integrated Publishing Toolkit (IPT) is a free open source software tool written in Java that is used to publish and share biodiversity datasets through the GBIF network. Designed for interoperability, it enables the publishing of content in databases, Microsoft Excel spreadsheets, or text files using open standards namely the Darwin Core and the Ecological Metadata Language.You can also use a 'one-click' service to convert your metadata into a draft data paper manuscript for submission to a peer-reviewed journal.

Since v2.2, the IPT has been capable of automatically connecting with either DataCite or EZID to assign DOIs to datasets. This new feature makes biodiversity data easier to access on the Web and facilitates tracking its re-use. You may read more about this and other new features introduced in version 2.2 here.
The core development of the IPT happens at the GBIF Secretariat, but the coding, documentation, and internationalization are a community effort and everyone is welcome to join in. New versions incorporate the feedback from the people who actually use the IPT. In this way, users can help get the features they want by becoming involved. The IPT really is a community-driven tool.
You can see the work that has gone into each iterative version since v2.0.3 (released in November 2011) under the Releases tab. You can check out the Stats page to find out how many institutions around the world are using the IPT today.
