The Ecological Metadata Language (EML) is a metadata standard developed by the ecological community for persistence, discoverability, and reuse of ecological data. EML extends the data lifespan allowing new insights and knowledge to be derived many years from now. While the highly detailed .xml structure of EML is necessary to organize and make searchable the metadata content, it confronts the inexperienced data provider with a steep learning curve that few have time to tackle. To overcome this we’ve created the EML Assembly Line, a linear process helping you craft high quality EML yourself! The EML Assembly Line is useful for publishing one-off datasets or providing a foundation for an EML factory. The EML Assembly Line R code package is available for download and development at our GitHub (https://github.com/EDIorg/EMLassemblyline). See you there!

EDI is now registered with the Registry of Research Data Repositories (re3data.org). Our re3data.org entry and DataCite citation record can be found under the following URL: http://www.re3data.org/repository/r3d100010272.
re3data.org is the largest and most comprehensive registry of research data repositories available on the web. It covers data from a wide range of disciplines and from around the world.
DataCite is a leading global non-profit organisation that provides persistent identifiers (DOIs) for research data. Their goal is to help the research community locate, identify, and cite research data.
When data packages are uploaded to the EDI Data Repository, they are first analyzed by a suite of quality checks that are used to report on certain aspects of metadata conformance to best practices as well as on the congruence between the metadata and the data. In early May, EDI added four new quality checks to its suite, bringing the total to thirty-six in all. A team comprised of EDI personnel and other data managers, called the EML Checker Working Group, oversees the design, implementation, and deployment of new and existing quality checks.
The EDI Data Repository, through its underlying PASTA+ web services API, now supports access to data package resource maps compliant with the Open Archives Initiative Object Reuse and Exchange (OAI-ORE) standard (https://www.openarchives.org/ore/). OAI-ORE defines standards for the description and exchange of aggregations of Web resources. A resource map can be accessed from the EDI Data Repository in OAI-ORE format by appending the string “?ore” to the standard web service URL used for accessing a data package resource map. For example, to access the OAI-ORE resource map for data package identifier edi.1.1, use the following URL: https://pasta.lternet.edu/package/eml/edi/1/1?ore.
