Provenance defects. Current initiatives to effectively manage, share, and reuse ecological data are indicative of the increasing importance of data provenance. Examples of these initiatives are National Science Foundation Datanet projects, DataONE and Data Conservancy, as well as the U.S. Global Change Research Program. Some international academic consortia, such as the Research Data Alliance, have specific group to tackle issues of provenance. In that case it is the Research Data Provenance Interest Group. Within computer science, informatics uses the term 'provenance' to mean the lineage of data, as per data provenance, with research in the last decade extending the conceptual model
