The NISO began exploring issues around vocabulary development and maintenance in 2013. In 2014, they proposed three projects around vocabulary use and reuse, documentation, and preservation. These projects examine policies, social considerations, and guidance needed to support stable vocabularies. The groups aim to limit "orphan vocabularies" and provide recommendations for responsible long-term governance, documentation, and adoption of at-risk vocabularies. Educational webinars were held in 2015, and a draft of best practice recommendations is planned for fall 2016 to support interoperability and understanding of vocabulary management issues.
