EML Best Practices

This document contains current ‘Best Practice’ recommendations for EML content for metadata related to ecological and environmental data. It is intended to augment the EML schema documentation (Jones et al. 2019) for a less-technical audience. This is one component of several resources available to EML preparers. These recommendations are directed towards the following goals:

  • Provide guidance and clarification in the implementation of EML for datasets
  • Minimize heterogeneity of EML documents to simplify development and re-use of software built to ingest it
  • Maximize interoperability of EML documents to facilitate data synthesis
