Overview 3 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

In literature 
 “Dean points out the need of having simple and interoperable subject schema for metadata to ensure usability by non- catalogers and to enable users to search across both discipline boundaries and across information retrieval and storage systems.” � Dean (2004) � 4 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

In literature 
 “Web environment opens up new uses for authority records and new objectives to augment the traditional objectives.” The cataloguing community is moving “from the stand-alone authority files of a single institution, or even from the shared online files towards a goal of sharing authority files among all communities” � Tillett (2004) � 5 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Uniquely identifying a person 
 How do we pull all the information about researchers from various databases and obtain the best possible aggregated data? 10 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Why URIs? 
 Brickley (2011) states that “the strength of a URI- based approach is that the same URI can be given different expressions, allowing semantically different forms to be mapped and rich connections to be made between content.” The governance is required to ensure that the stated relationships are valid and useful in the contexts that they are practically being used. 11 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Background 12 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

How do we get there? � “The Web has evolved and now it offers something more powerful: linked data, which represents each piece of data as a link between two objects. These links, or URIs, enable software reasoners to derive knowledge that is human- specific.” � 13 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Ideal solution Cataloger should be able to control name headings with established form of name not only from LCNAF Think beyond individual systems in terms of global approaches that would connect and enable the exchange of information between all the systems. 14 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Ideal solution ORCID ¡ LC ¡NAF ¡ VIVO ¡ OCLC ¡ And much more … 15 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Ideal solution: not there yet The bibliographic utilities (OCLC and SkyRiver) and the vendor community which includes Integrated Library Systems (ILS), automated authority control vendors, contract cataloging vendors and publishers, are not ready yet to offer a technical environment that enables us to control the name headings that come from linked data products and services. 16 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

The solution VIVO URI … 17 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

VIVO VIVO is an open, shared platform for connecting scholars, research communities, campuses and countries using Linked Open Data. VIVO links data from institutional and public sources to create web profiles populated with researcher interests, activities and accomplishments. 18 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

feturedIn property in VIVO-ISF featuredIn property defined as: “This relates a person to an information resource that contains a featured article on that person” (vivoweb .org/files/vivo-isf- public-1.6.owl) Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

feturedIn property in VIVO-ISF For example if we have a person that is represented in our VIVO instance with the following URI: http:// vivo.northwestern.edu/ individual/nbf813378 and we have an article featuring him in a VIVO instance the relationship is represented as in the image Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

feturedIn property in VIVO-ISF representing the featuredIn relationship between the person and a book, a biography, or any other publication type Is this enough to represent the relationship between a person as a subject? Is this enough to capture the aboutness in the sense it is defined? Do we need a property that will have agent in the range and be defined in the domain of information content entity (ICE) ? 23 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Capturing non-traditional data Enhancing the authority records with the VIVO URIs, or any other URIs, by adding the values in the field 024, first indicator 7 with the value of the URI in subfield a as shown below: 024 7 # $a http://vivo.northwestern.edu/ individual/nbf813378 $2 uri 600 10$a Abbott, James D. $0(uri) http:// vivo.northwestern.edu/individual/nbf813378 24 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Use of ORCID, ISNI, VIAF in authority files Why not use machine readable URIs? 25 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

Back to ideal solution VIVO, OCLC and possible partnership Why not use http://vivo.cornell.edu/individual/ individual22972 We have discussed the possibility of moving towards creating persistent VIVO URIs that resolve at the central VIVO Registry, which represents a hub aggregation of all of the local deployments. 26 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

VIAF, VIVO, NCBI, ORCID and possible partnerships Linking across data sources - Example: sameAs link? VIVO ¡Registry ¡URI ¡ Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal
