Work Level Record

Create a landing page summarizing content for a work

Work Level Record: Objective

The world’s libraries. Connected.

• The Content Cluster• Enables better work record displays by reducing the number of lines that

display for large works

• Enables a choice of format and presents the formats that could be acceptable substitutes

• Consolidates holdings for identical content 

• The Manifestation Cluster is important

• Consolidates holdings at manifestation level

• In the short term allows the record catalogued in the language of the interface to be chosen for display

• Reduces apparent duplication

• Allows a more accurate count of the number of manifestations in WorldCat (as opposed to the number of records)

 

GLIMIR

The world’s libraries. Connected.

Creates true multi-lingual displays• At work and manifestation levels

• Using all available data instead of “most appropriate record”

• Generates data

Corrects many of the 28 million records coded “und”

Better control and linking of translations

Input to refinement of work clusters

Smarter data storage

Multilingual Bibliographic Structure Project

The world’s libraries. Connected.

• Worldcat.org selects the most appropriate record to show to a user as representative of the work in the short result list and beyond

• The end result will not be very satisfactory from a multi-lingual viewpoint… here’s why

“Most appropriate” questioned

Most appropriate display

Build the display from all available

data

The world’s libraries. Connected.

• Work level data, mined from all associated bibliographic records will be displayed supplemented with expression / manifestation level data as the user drills through the short to fuller versions of the metadata.

Multilingual Bibliographic Structure Project

End user interface will show works and manifestations not bibliographic records; the cataloguing client will also show bibliographic records

Translations

The world’s libraries. Connected.

• The cream of the world’s cultural and knowledge heritage is shared by being translated

• WorldCat contains many rich cataloguing records for these translations

Great works are translated

GOAL: Data mine the really good records to improve clustering, presentation, authority

records and linked data

The world’s libraries. Connected.

• Inconsistencies causing work clusters to be incomplete & less than optimal search results

• Titles without subtitles

• Different forms of uniform title or missing uniform title

• Inverted title

• Different coding of original and translated information

Translations

Generated uniform title authority records will overcome most of these differences without needing to edit individual records

The world’s libraries. Connected.

• Improve FRBR work groups

• Made by data mining

• Contribute to VIAF

• Diffuse via VIAF as linked data

• Possibility to create web page / web service

Generate uniform title authority records

Translation records in VIAF

• Will enrich VIAF significantly

• New elements - translated title and translator

Author Title Expressions in VIAF Translation count in WorldCat

• Records are freely available to the world from VIAF in

• MARC-21

• XML

• RDF (linked data)

• Just links in JSON

• And other formats as introduced

Diffusion of Translation records

• # of manifestations as opposed to # of records

• # of works that have translations

• Top translated authors and works

• And more
