NISO publishes recommended practice on metadata indicators for accessibility and licensing of e-content

摘要

The National Information Standards Organization (NISO) has published a new Recommended Practice on Access License and Indicators (NISO RP-22-2015) that defines metadata to be used to indicate free-to-read content and a link to license terms for the use/ re-use of that content. Developed by the NISO Working Group on Access License and Indicators (formerly Open Access Metadata and Indicators), the recommended practice proposes the adoption of two core pieces of metadata and associated tags: and . The first tag would indicate that the work is freely accessible during the specified timeframe (if applicable). The second tag would contain a reference to a URI that carries the license terms specifying how a work may be used.
