“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)

“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)

Uniquely identifying a person


10 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

How do we pull all the information about researchers from various databases and obtain the best possible aggregated data?

Why URIs?


11 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

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.

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.”

Ideal solution

14 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

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.

Ideal solution

LC ¡NAF ¡ ORCID ¡ VIVO ¡

And much more …

Ideal solution: not there yet

16

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.

The solution

17 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

VIVO URI …

VIVO

18 Violeta Ilik UDC Seminar, October 29, 2015 Lisbon, Portugal

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.

RDF for VIVO: from CSV to RDF via Karma

feturedIn property in VIVO-ISF

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

featuredIn property defined as: “This relates a person to an information resource that contains a featured article

• n that

person” (vivoweb .org/files/vivo-isf- public-1.6.owl)

For example if we have a person that is represented in

• ur 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

23

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)?

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

Use of ORCID, ISNI, VIAF in authority files

25

Why not use machine readable URIs?

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

Back to ideal solution

VIVO, OCLC and possible partnership

26

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.

Why not use http://vivo.cornell.edu/individual/ individual22972

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

Linking across data sources - Example:

VIVO ¡Registry ¡URI ¡ sameAs link?

VIAF, VIVO, NCBI, ORCID and possible partnerships
