Xiaoli Li Co-head of Content Support Services University of California Davis Library Canadian Linked Data Summit, Oct 24, 2016

2 Outline What Is BIBFRAME? What IS BIBFLOW? Roadmap (Data Flow)
Discovery Information Flow Cataloging Data Flow If Authority Exists Cataloging Data Flow if No Authority Found

3 PART I: What Is BIBFRAME?
BIBliographic FRAMEwork Initiative

4 What Is BIBFRAME? Library Congress’ project started in 2011
It’s the replacement for MARC can and will serve as an encoding standard for RDA and other content standards AND It leverages the current web technology (sematic web/Linked Data) and uses Resource Description Framework (RDF) modeling practice.

5 BIBFRAME 2.0 Model RDA Work RDA Expression RDA Manifesta-tion RDA Item

6 Goals for BIBFRAME Supply search engines with description in a form they can exploit Use/exploit linking traditional = textual, identifiers semantic technology = URIs URI – Uniform Resource Identifier MARC transition enable reuse of data from MARC provision of transformations to new models Extensibility to new and broader content Accommodate needs for different types of libraries New views of different types of metadata descriptive, authority, holdings coded data, classification data, subject data preservation, rights, technical, archival Reconsideration of the data related activities exchange, internal storage, input interfaces and technique Adapted from a presentation given by Sally McCallum,

7 PART 2: What Is BIBFLOW? BIBframe + workFLOW

8 BIBFLOW Project Is a 2-year project of the UC Davis University Library and Zepheira, funded by Institute of Museum and Library Sciences (May 2014 – April 2016) Its official title is “Reinventing Cataloging: Models for the Future of Library Operations” Is a research project that will address questions like “What impact will adoption of BIBFRAME on technical services workflows in an academic library”? Its primary purpose is to understand ecosystem, test solutions, and provide a roadmap of how libraries can iteratively migrate to linked data without disrupting patron or business services.

9 Ruth Fischer and Rick Lugg, Study of the North American MARC Records Marketplace,

11 This complexity leads to the inevitable conclusion that moving away from MARC into BIBFRAME represents an evolutionary leap for libraries and not a simple migration.

12 What Have We Done? Analyzed cataloging workflows Tested pulling data from OCLC using BIBFRAME Scribe Tested pulling data and URI from LC using BIBFRAME Scribe Explored conversion of MARC records to BIBFRAME LC’s MARC to BIBFRAME Transformation Service Zepheira’s transformation tool (password required) Developed a roadmap

13 PART III: Roadmap MARC to BIBFRAME

14 Roadmap: Primary Stakeholders
Triplestore Human Discovery LD Editing Interface Machine Discovery Vendors ILs

15 Roadmap: Ecosystem (Hybrid: MARC + BIBFRAME DATA)

16 1. Discovery Information Flow

17 Step 1: User Submits Search Query
Discovery Interface User Submits Search Request SPARQL Endpoint Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB Authorities MARCURI Step 1: User Submits Search Query

18 Step 2: Query Results Returned as Thin Local Graph
Discovery Interface SPARQL Endpoint Search Results Returned (Thin local Graph) Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB Authorities MARC URI Step 2: Query Results Returned as Thin Local Graph

19 Step 3: User Requests Detailed Graph for Item
Discovery Interface User Submits Request for Item Detail SPARQL Endpoint Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB Authorities MARC URI Step 3: User Requests Detailed Graph for Item

20 Step 4: Complete Local Graph Returned
Discovery Interface SPARQL Endpoint Full Local Graph Returned Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB Authorities MARCURI Step 4: Complete Local Graph Returned

21 Supplemented by OCLC Schema.org graph
Prior to display, returned graph is supplement with OCLC Schema.org graph data using linked OCLC Work URI Discovery Interface SPARQL Endpoint Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB Authorities MARC URI Step 5: Graph Supplemented by OCLC Schema.org graph

22 Step 6: Graph Supplemented by Authority Graphs
Prior to display, graph is supplemented with authority data linked via local and OCLC graph nodes Discovery Interface SPARQL Endpoint Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB Authorities MARCURI Step 6: Graph Supplemented by Authority Graphs

23 Graph Building (steps 4, 5 & 6)
Triples in the rectangle forms a record view which is displayed to a user via discovery interface

24 Step 7: Holding and Availability Info Added
Discovery Interface SPARQL Endpoint Graph data supplemented with holding and availability data from ILS Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB Authorities MARCURI Step 7: Holding and Availability Info Added

25 Step 8: Completed Graph Displayed to User
Discovery Interface SPARQL Endpoint The detailed view is displayed to the user after the complete graph has been assembled from various sources. Note that the computer is capable of handling each of the steps involved in the process in fractions of a second, so the user does not experience any delay more than now.

37 X Step 4: Attempt to Pull Authority, but no Match Found Discovery
Interface SPARQL Endpoint Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB X Authorities MARC URI Step 4: Attempt to Pull Authority, but no Match Found

38 Step 5: Cataloger Enters new Entity Data
Discovery Interface SPARQL Endpoint Triplestore OCLC ILS BIBFLOW:SCRIBE LD Cataloging DB When a bib and authority cannot be found, the cataloger enters data (name, dates, etc.) directly into the cataloging interface. Authorities MARC URI Step 5: Cataloger Enters new Entity Data

39 Step 6: Push New Descriptive and Entity Data to Triplestore
Discovery Interface SPARQL Endpoint Triplestore On submission, a new item graph and a new Entity graph are created in Triplestore with a unique URI for each. Cataloger submits the graph, including information about the item and the new Entity OCLC ILS BIBFLOW:SCRIBE LD Cataloging Authorities MARC URI Step 6: Push New Descriptive and Entity Data to Triplestore

40 Step 7: Item Graph and Entity Graph Pushed to OCLC for Reconciliation
Discovery Interface SPARQL Endpoint New entity graph and item graph are pushed to OCLC for reconciliation. OCLC service either connects to existing, overlooked bib and authority or creates a new bib and Authority and links entities to the new Authority and work. The reconciliation service provides a publicly accessible (LOD) and machine actionable map of “Same As” relationships between entities and Authorities.
