Pull quote: “If broadly adopted, the National Library of Sweden’s approach frees us from the eternal lipstick-on-pig question of how best to present eccentric, often inadequate, almost always expensively homegrown data to patrons. Instead, we will put the patron experience first, asking, ‘What data do patrons actually want to see or use, and before we go creating it, does it perhaps exist already in the vast existing web of data?’”

Pull quote: “WorldCat.org is now publishing linked data for hundreds of millions of bibliographic items – that’s a heck of a lot of linked data by anyone’s measure. By far the largest linked bibliographic resource on the web. Also it is linked data describing things, that for decades librarians in tens of thousands of libraries all over the globe have been carefully cataloguing so that the rest of us can find out about them. Just the sort of authoritative resources that will help stitch the emerging web of data together.”

Pull quote: “With the addition of Schema.org mark-up to all book, journal and other bibliographic resources in WorldCat.org, the entire publicly available version of WorldCat is now available for use by intelligent Web crawlers, like Google and Bing, that can make use of this metadata in search indexes and other applications.”

Pull quote: “After five long years, they had 12 million objects in the database. And they were purchased by Google. In the first year after the acquisition, they had 25 million things. What did Google bring to the acquisition, aside from money? Data, of course, of a very specific kind. Before, they were just guessing at what people might want to know (cheese, rivers, highways, etc). With Google’s search data, they *know* what users are after, so they can go about finding and making that information available. With Google’s help, their database has grown rapidly to over 500 million items objects. That’s orders of magnitude larger than previous attempts to educate artificial intelligences like the Cyc project out of the University of Texas. (Though it should be noted that Cyc has some capabilities that the Knowledge Graph does not.)”

Pull quote: “We treat library users as if they are all-knowing; as if they know each author in our catalog, as if the title of the book and the number of pages is sufficient for them to decide if it is a good read or has the information they need. This is so obviously false that I am at a loss to explain how we continue to work under this illusion.”

Pull quote: “It is possible that we can skip the relational database phase of our data development and move directly into a semantic web model. However,  to think that data created following RDA instructions, which is not even suitable for a relational database, could be made usable on the semantic web without major modifications is simply wrong. If we create a bibliographic framework that takes RDA as it has been described and ports that, unchanged, to RDF we will create a data model that does not serve us, does not serve our users, and that cannot reasonably interact with other linked data on the web.”

Pull quote: “Whether or not you think you have any idea what linked data is, any time you click a ‘like’ button on a website or sign up for a social sharing app in Facebook, you are participating in the semantic web. But every time that data link goes behind a Facebook wall, it fails in being open linked data. Just as librarians have always worked to keep the world’s knowledge available to all, we must continue to ensure that potentially important linked data is kept open as well–and with no commercial motive.”

Pull quote: “Under the shift, people who search for ‘Lake Tahoe’ will see key ‘attributes’ that the search engine knows about the lake, such as its location, altitude, average temperature or salt content. In contrast, those who search for ‘Lake Tahoe’ today would get only links to the lake’s visitor bureau website, its dedicated page on Wikipedia.com, and a link to a relevant map. For a more complex question such as, ‘What are the 10 largest lakes in California?’ Google might provide the answer instead of just links to other sites.”
