  • 1.  Introducing OCLC Meridian

    Posted May 09, 2024 10:08 AM


    I am sharing this message with you on behalf of my colleagues.

    We're excited to announce the availability of OCLC Meridian, a web application and set of APIs that libraries and other organizations that manage metadata for knowledge collections can use to create, curate, and connect linked data entities.

    Meridian enables metadata professionals to:

    • Create and curate linked data in WorldCat Entities. These entities-such as Persons, Works, Places, Organizations, and Events-can be integrated with existing MARC records and connected to other datasets, systems, and services.
    • Connect nonlibrary datasets within your institution or in other disciplines. WorldCat Entities can be created to connect and describe information in any other dataset that supports standard linked data technology, providing centralized linked data descriptions that can inform research, analysis, and discovery across many diverse types of data.
    • Improve library discoverability and relevance. WorldCat Entities data is available for libraries, partners, and services across the web to access in new ways so that important resources and knowledge collections are visible and useful in many more online environments.
    • Emphasize important relationships. Guidance in the WorldCat ontology helps users establish very detailed relationships between entities, making connections that can enhance research, discovery, and analysis.

    The launch of Meridian represents another significant step forward in the evolution of library metadata.
