The National Information Standards Organization (NISO) has announced the publication of a new recommended practice, Improving OpenURLs Through Analytics (IOTA): Recommendations for Link Resolver Providers (NISO RP-21-2013). These recommendations are the result of a three-year study performed by the NISO IOTA Working Group in which millions of OpenURLs were analyzed and a Completeness Index was developed as a means of quantifying OpenURL quality.
By applying this Completeness Index to their OpenURL data and following the recommendations, providers of link resolvers can monitor the quality of their OpenURLs and work with content providers to improve the provided metadata - ultimately resulting in a higher success rate for end users. The project is summarised in a technical report, IOTA Working Group Summary of Activities and Outcomes (NISO TR-05-2013), which was published along with the recommended practice.
The IOTA Recommended Practice and Technical Report are both available for free download from the IOTA Working Group's page on the NISO website at: www.niso.org/workrooms/openurlquality.
