PPSR_CORE Metadata standards
The collaborative success for citizen science and public participation in scientific research (PPSR) led to the development of the PPSR_CORE Program Data Model Metadata Standard / data sharing protocol. Sharing information across databases maximizes everyone's efforts, getting more "bang for the buck" out of information about citizen science projects everywhere. It leads to current, up-to-date, and synchronized project lists and a broader understanding about citizen science globally.

Over the fall of 2013, organizations supporting citizen science came to a landmark agreement - to share basic information across databases that catalog citizen science projects. The collaborative success for citizen science and public participation in scientific research (PPSR) led to the development of the PPSR_CORE Program Data Model Metadata Standard / data sharing protocol. Sharing information across databases maximizes everyone's efforts, getting more "bang for the buck" out of information about citizen science projects everywhere. It leads to current, up-to-date, and synchronized project lists and a broader understanding about citizen science globally.
The Need
With the proliferation of citizen science, a number of organizations have been cataloging projects to offer support, network practitioners, and/or track outcomes. These efforts are complementary. Up-to-date information about citizen science projects is valuable to both project leaders and researchers, but the task of entering and maintaining this information in multiple places is cumbersome
The Significance
By agreeing to openly share core data fields about projects, the citizen science community benefits:
- project leaders can add and edit information about their project in a single place of choice
- project information can be shared and synchronized automatically across all participating databases
- project updates in one database are reflected, in real time, across multiple databases serving a variety of purposes
those searching for projects can do so from any provider and be confident results contain the most up-to-date information
The Team
Several core founding organizations started the PPSR_CORE initiative (below) and we are now forming an international working group within the Citizen Science Association to continue this important work.
