What is BIBFRAME
• BF can be seen as a replacement of MARC:• BF can and will serve as an encoding standard for RDA and other content
standards
• But, it’s not only a replacement of MARC:• BF is an environment/model/ontology focusing on bibliographic data

Use Cases
• 15 use cases are defined by the Use Cases and Requirements document: • http://bibframe.
org/documentation/bibframe-usecases/
For library users
For librarians
Requirements and Design Objectives• Web oriented architecture
Linked Open DataExpressed in RDF
• Resource identity• Property identity• Vocabulary evolution• Localized extensibility• Third party value add• Defined serialization to support interchange
Requirements and Design Objectives (cont.)• Minimize ontology mechanics• Web oriented search
SPARQL (though not a requirement)
• Support legacy and existing search technologiesSearch/Retrieval via URL (SRU) / Contextual Query Language (CQL)Z39.50OAI-PMH
• Enabling web triggers• Internationalization

Model
• Work• Instance• Authority• Annotation
http://de.slideshare.net/zepheiraorg/bibliographic-14207718
Work
• “A BIBFRAME Creative Work, abbreviated simply as Work, reflects a conceptual cataloging item.”• But, a BF work is not a FRBR/RDA work:
http://de.slideshare.net/zepheiraorg/alabibframe-lc20130630
Instance
• “BIBFRAME Instances reflect an individual, material embodiment of a BIBFRAME Work that can be physical or digital in nature. “• Each BF Instance is an instance of one and only one BF work.
• A BF Instance is basically a FRBR Manifestation, because information about BF Item largely belongs to BF Annotation.
Authority
• “BIBFRAME Authorities are key authority concepts that are the target of defined relationships reflected in the Work and Instance.”• BF Authority are not to compete or replace existing authority systems,
but to provide a “common, light weight abstraction layer” over these authority efforts to make them more effective.• According to the discussion paper about BF Authority, nine categories
of Authority are currently defined:• Family, Jurisdiction, Meeting, Organization, Person, Place, Topic, Classification,
and Temporal Concept
Authority Implementation 1: current design
Using BIBFRAME authority resources
Authority Implementation 2: “direct” approach
• This method, by linking directly to the authority resource, is desired by most stakeholders;• It can be used for classification,
if LD versions of DDC and LCC are to be used in the future;• However, this approach is less
flexible than the first approach, making it harder for BF to be a “common, light weight abstraction layer”.
Authority Implementation 3: role resource
• This method provides the highest level of flexibility, especially the “ability to handle controlled role information”;• However, it may also
result in unnecessary complexity.
Authority Implementation 4: LCSH
Annotation
• “In general, an Annotation asserts information about a resource; a BIBFRAME Annotation asserts information about a BIBFRAME resource.”• Annotation can be linked to both Work and Instance• Annotation is about institution-specific information
• http://bibframe.org/documentation/annotations/
Use Cases/Types of BF Annotation
• 4 use cases are defined by BF Annotation Model (2nd draft ver.):• Cover art• Holdings• Reviews• Descriptions
• Including summary, abstract, and table of contents
An Example of Holding Information1 <http://xyz.org/bibframeTestCases/Annotations/Annotation/
Holding>a bf:Holding;

5 bf:heldBy < http://id.loc.gov/vocabulary/organizations/dlc> ;
6 bf:subLocation "Jefferson or Adams Building Reading Rooms" ;
7 bf:callNumber "PS3572.O5 B5 1987C" ;

10 bf:copyId "71234" ;
11 bf:circulationStatus "non-circulating" ;
12 bf:accessCondition "Access is restricted; consult library for details" .
Vocabularies
• BF Vocab is still being established.• Constant updates are still going on.
http://bibframe.org/vocab/
Components of BF Vocabulary
• Resource:• Four major classes (WIAA), and their specific types
• Properties:• A resource may have different properties when used with different roles
• Values:• One of the examples is the resource types in the discussion paper
BIBFRAME Resource Types
• Discussion paper• http://bibframe.org/documentatio
n/resource-types/
• Only include subclasses of the CreativeWork class, rather than those of Instance class• The proposed list is a melding of
MODS, MARC and RDA lists
• Language material: Cartography:
• Dataset:
• Notated music: Notated movement:
• Audio:
• Still image:
• Moving image
• Three dimensional object:
• Software/multimedia:
• Mixed material
• Collection:
• Manuscript:
• Tactile:
Observations
• 1. Even though BF seems to have a promising future, it’s still in the very early stage• There is a small but active community; conversations are active• More documents, bridges … need to be designed in the coming years, before
it can actually serve as a replacement of MARC 21, if not more
Observations
• 2. Use cases are important• Nine use cases for BIBFRAME model have been identified from the
perspectives of end users as well as librarians, but…• More need to be identified for each section of BF, especially for annotation
and authority, from broader scopes:• “It seems to me that the decision to be made isn't so much about the structure of the
authority but the anticipated uses, including vocabulary maintenance (as you mention) and linking to other communities that create bibliographic data.” -- Karen Coyle ([BIBFRAME] Authority - Treatment of role data)
• Use cases in local contexts need to be considered for local implementations
Questions
• Is it possible to integrate bibliographic data into the bigger data world?
