The PASTA+ data repository software is actively developed and managed by the Environmental Data Initiative (EDI), a National Science Foundation (NSF) funded project through the Division of Environmental Biology (DEB) under grants #1565103 and #1629233. EDI institutional support comes from the University of New Mexico and the University of Wisconsin, with Principal Investigators Dr. Mark Servilla and Dr. Corinna Gries, respectively. The EDI grant period of performance is from July 2016 through June 2019. Please refer to the project’s website (here) for more information about the Environmental Data Initiative.

PASTA+ began as the Provenance Aware Synthesis Tracking Architecture (PASTA), an informatics project [1] of the Long Term Ecological Research (LTER) Network Office. Initial design and development of PASTA began in late 2009, with the culmination of a production deployment in January 2013 as the core infrastructure of the LTER Network Information System (NIS). The LTER NIS was the de facto and exclusive data repository for research data products of the LTER Network. PASTA supported the upload and archive of ecological data packages (science data and metadata), which consist mostly of tabular data, but may include other products such as audio, imagery, or binary objects. The moniker “PASTA” transitioned to “PASTA+”, along with dropping the acronym for the Provenance Aware Synthesis Tracking Architecture, in July 2016 with the end of the LTER Network Office project and the beginning of the Environmental Data Initiative.

PASTA+ is now the core infrastructure of the EDI Data Repository and supports environmental and ecological data products from the NSF programs for the Long Term Research in Environmental Biology (LTREB), Organization for Biological Field Stations (OBFS), MacroSystems Biology (MSB), and Long Term Ecological Research (LTER). The EDI Data Repository is an open archive and accepts data from publicly funded programs and projects within the United States of America and beyond. As of July 2018, there are 42,800 unique data packages in the EDI Data Repository. EDI also manages two Data Portals, the EDI Data Portal and the LTER Data Portal, which interact directly with PASTA+ software through its REST web-service API and serve as a reference implementations for how to use the API in a web applications. Questions or feedback may be sent to support@edirepository.org. The PASTA+ software may be accessed through our GitHub repository at PASTAplus/PASTA.

[1]Funding for PASTA was derived from both the NSF DEB and the American Recovery and Reinvestment Act of 2009.
