OCLCs Linked Data Initiative:Using Schema.org to Make Library Data Relevant on the Web

摘要

In June of 2012, OCLC announced the next stage of its Linked Data strategy when it revealed that Schema.org markup had been added to WorldCat.org pages under an Open Data Commons license (ODC-BY). This technique provided a platform to present the metadata and holdings for millions of bibliographic items held by tens of thousands of libraries to the large commercial search engines for use in their search indexes and applications. The Schema.org initiative-made up of Google, Bing, Yahoo, and Yandex-provides a core ontology for search engines and other web crawlers to directly make use of this library data. Schema.org represents a cooperative agreement between these major search engines to share a core vocabulary for markup. It helps the search engines to normalize the markup of webpages in a way that reduces ambiguity about what the pages are describing and makes the integration of the data into search engines more efficient.
