1 Making MODS to Linked Open Data: A Collaborative Effort for Developing MODS/RDF Denenberg, Ray Guenther, Rebecca Han, Myung-Ja Luna Lucero, Brian Mixter, Jeff Nurnberger, Amy L. Pope, Kathryn Wacker, Melanie *Names listed alphabetically IFLA 2014 Satellite Meeting - Linked Data in Libraries

2 Metadata Object Description Schema (MODS) Descriptive metadata standard Designed for descriptions of digital objects Derivative of MARC Expressed in XML, draft RDF ontology available Maintained by the Network Development and MARC Standards Office of the Library of Congress Community input Popular exchange format 2IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

3 Based on MARC, but … Subset of MARC elements L anguage based tags Extensible with other schemas Hierarchical Allows for inclusion of URIs 3IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

9 Challenges Goals Logistics - Closed listserv - GitHub page - Working group calls 9IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

10 Some agreements reached attributes Superfluous wrappers [top level elements] Single vs. Dual properties 10IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

11 Has an enumerated list of values, e.g., text, cartographic, notated music, and etc. in MODSXML Will be represented in MODS/RDF as For example: ypes/Txt 11IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

12 attributes : Suggested not enumerated list, but certain types will be retained as properties (e.g. ownership, funding, thesis, exhibitions) Suggested values: scope, subject, content advice, review not retained : restriction on access, use and reproduction retained 12IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

13 Superfluous wrappers [top level elements] 1. Top level element Not used as a wrapper and will be eliminated in MODSRDF Associated subelements will be treated as direct properties: formreformattingQualityinternetMediaType extentdigitalOriginnote 13IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

14 Superfluous wrappers [top level elements] 2. Top level element Not used as a wrapper Decisions on how to treat subelements: - “superclass” event with subclasses for typical events such as publication, manufacture, etc. -,, as separate properties 14IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

15 Vocabulary Term as Object of a Triple: Single vs. Dual Property Single property URI pto:. a pto:Book; modsrdf:language ;. Single property Literal Used a pto:Book; modsrdf:language "french";. 15IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

16 Dual Properties URI Used a pto:Book; modsrdf:language ;. Literal Used a pto:Book; modsrdf:languageLiteral "french";. Vocabulary Term as Object of a Triple: Single vs. Dual Property 16IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

17 Under Discussion Linking to other entities Titles Defining properties for roles Classification relatedItem 17IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

18 Linking to People, Places, Organizations, Events etc. LC MODS RDF approach: MADS RDF inline Direct approach BIBFRAME approach New Framework 18IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

19 Direct vs. Indirect Direct pto:. a pto:Book; modsrdf:creator ; 19IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

20 Direct vs. Indirect Indirect pto:. a pto:Book; modsrdf:creator ;. a modsrdf:Person; modsrdf:label "Huxley, Aldous, "; modsrdf:variantLabel "Huxley, Aldous (Aldous Leonard), "; modsrdf:variantLabel "Huxley, Aldous"; modsrdf:hasAuthoritativeDescription ; 20IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

21 Titles title types:,,, name/title parse out,,, or as a single string? 21IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

22 Working with Other Library Linked Data Developments Create mapping between MODS (MODSRDF) and selected other library linked data development, e.g., BIBFRAME, schema.org, Europeana... Gather use cases with other library linked data works Develop best practice document for MODS user community 22IFLA 2014 Satellite Meeting - Linked Data in Libraries8/14/2014

23 Questions for Discussion Are you working on similar Linked Data projects? If so, are you having the same discussions/questions? What are your goals/expectations for using Linked Data? Do you have use cases for MODS records as Linked Data? 8/14/2014IFLA 2014 Satellite Meeting - Linked Data in Libraries23
