Why are these not useful?

▪ Some fields should be required▪ Some fields should not be repeatable▪ Fields should be entered in a consistent

format▪ Some fields should be from a standard

vocabulary

▪ (It’s hard to ingest a PowerPoint slide into your ILS)

Dublin Core in Kentucky Digital Library

▪ Dublin Core is the core of its metadata

▪ Accepts data / metadata submissions from all over the state

▪ Not enough time / subject expertise to do all description here

▪ Guidelines describe specifics of metadata that should be provided

KDL Guidelines: Which elements?

Required fields must be submitted in order for content to be ingested:

▪ format▪ language▪ Kentucky-specific

subject▪ resource type▪ rights▪ title

Required if available:▪ creator▪ date▪ source

Other elements (EAD):

▪ biography/history▪ scope and content▪ arrangement

KDL Guidelines: Format/Vocabulary

▪ Date: To enhance discoverability and automated maintenance processes, KDL requires the use of ISO 8601 for the entry of the most date fields; in other words, KDL uses the standard form of YYYY-MM-DD. This is used in Date, Terminal Date, Date Range Start and Date Range End fields.

▪ Language▪ Scheme: ISO 639▪ Examples: en, es

KDL Guidelines: How to encode?

▪ Submit fields through online form▪ Type with a certain format▪ Choose vocabulary from a pulldown menu

▪ METS template▪ Framework with descriptive elements / files▪ Block of Dublin Core according to guidelines

Data Model + Application Profile

▪ Dublin Core is a data model▪ Elements / Entities▪ Relationships

▪ Kentucky Digital Library has an application profile▪ Which elements are used▪ Which elements are required▪ Which elements are repeatable▪ Value restrictions – Format? Vocabularies?▪ How to encode in a standard way?▪ (any extras added?)

FRBR + RDA

▪ Functional Requirements for Bibliographic Records (FRBR)▪ Data model▪ Entities▪ Relationships

▪ Resource Description and Access (RDA)▪ Application profile for FRBR▪ Which elements are required (“Core”)▪ How should values be recorded/transcribed?▪ How should records be encoded?

Why bother with a profile?

▪ Why not just implement and index all fields and relationships?

▪ FRBR is HUGE

▪ Recording everything would take forever

▪ Elements can be recorded in different ways

Must specify and prioritizewith an eye to:

▪ Find

▪ Identify

▪ Select

▪ Obtain

▪ Find involves meeting a user’s search criteria through an attribute or a relationship of an entity. This can be seen to combine both the traditional “find” and “collocate” objectives of a catalog.

▪ When a patron enters something sensible, they should find (at least) the title they are looking for

▪ Once they have found something good, similar things should be one step away

Identify

▪ Identify enables a user to confirm they have found what they looked for, distinguishing among similar resources.

▪ A researcher should be able to work from a citation and find the original resource

▪ A copy cataloger should be confident they have found the right record

Select

▪ Select involves meeting a user’s requirements with respect to content, physical format, etc. or to reject an entity that doesn’t meet the user’s needs.

▪ Is the novel in English? Is it in large print?

▪ Is the movie on DVD or VHS?

▪ Is it a basic math text, or research level?

Obtain

▪ Obtain enables a user to acquire an entity through purchase, loan, etc., or electronic remote access.

▪ Online resource records should include working links to the resource

▪ Physical items should have a call number

Why FRBR? (Simpler?)

FRBR model is more complex

Manifestation

FRBR allows more relationships

MANY more relationships(only some reciprocal)

Many works have only one expression and manifestation

A work might have two expressions

FRBRization?

▪ Many catalogs now claim to do “FRBRization”, but…

▪ “FRBR is a matter of display, so it will be handled by the discovery layer.”—An ILS vendor

▪ Manifestation records are identified as being the same work, and displayed as such in search results

Automatically detect relationships?

▪ Uniform titles might help us identify expressions of the same work

▪ Author + Title might help us identify manifestations of the same expression

▪ So we can do some grouping.

Related works?

▪ Sequels/Prequels?▪ Dramatizations?▪ Adaptations?▪ Analysis?▪ Whole/Part relationships?▪ Preceding/Succeeding titles?

Relationships: Single MARC fields

▪ Preceding/Succeeding titles▪ 780 00 ‡t Citizen (Berea, Ky.) ‡w (DLC)sn

85052076▪ 785 00 ‡t Berea citizen ‡w (DLC)sn 85052075

‡w (OCoLC)12249111

▪ Other forms▪ 776 08 ‡i Online version: ‡a Amodio, Mark. ‡t

Anglo- Saxon literature handbook ‡d Hoboken, NJ : John Wiley & Sons Inc., 2014 ‡z 9781118286494 ‡w (DLC) 2013005429

Relationships: More MARC fields

▪ Translations▪ 041 1_ ‡a chi ǂh eng▪ 240 10 ‡a臨濟錄 . ǂl English▪ 500 __ ‡a Translation from the Chinese

▪ Whole/part▪ 100 1_ ‡a Pokras, Barbara.▪ 245 10 ‡a Feeding Mrs. Moskowitz / ‡c Barbara

Pokras. The caregiver / Fran Pokras Yariv.

▪ 700 12 ‡a Yariv, Fran Pokras. ‡t Caregiver.▪ 740 02 ‡a Caregiver.

Relationships: MARC notes fields

▪ Based on:▪ 245 10 ‡a West Side story.▪ 500 __ ‡a Based on: Romeo and Juliet / William

Shakespeare.

▪ Remake of:▪ 245 10 ‡a Gaslight / ǂc Loew's Incorporated ;

directed by George Cukor …▪ 500 __ ‡a Remake of the 1939 motion picture,

Gaslight.

RDA provides more structure for recording relationships

▪ Between works:▪ 245 10 ‡a Nightlight / the Harvard Lampoon.▪ 700 1_ ‡i Parody of (work) : ‡a Meyer,

Stephenie, ‡d 1973- ‡t Twilight ‡w (DLC)2004024730

▪ Between expressions:▪ 245 00 ‡a Total recall / ‡c Columbia Pictures …▪ 730 0_ ‡i Remake of (expression) : ‡a Total

recall (Motion picture : 1990) ‡w (OCoLC)247127957

▪ Relationship designators are from an established vocabulary

Relationship designators have associated URIs

▪ URI = Uniform Resource Identifier▪ Looks like a URL▪ May or may not go to a live web page

▪ Parody of (work)▪ http://rdvocab.info/RDARelationshipsWEMI/

parodyOfWork

▪ Remake of (expression)▪ http://rdvocab.info/RDARelationshipsWEMI/

remakeOfExpression

URIs in a Linked Data environment

▪ If we could control relationships like headings:

▪ (actually storing the URI instead of the label text)

▪ Localization is moved to display▪ English catalogs could display the English label▪ German catalogs could display the German label

▪ No parallel records would be needed – we could use the same records!

‡i Parody of (work) : ‡a Meyer, Stephenie, ‡d 1973- ‡t Twilight ‡w (DLC)2004024730

What is being linked?▪ Some relationship designators refer explicitly to links

between works or expressions

▪ It seems weird to use them to link manifestation records

▪ It is probably not harmful; ambiguous terms are qualified▪ Form of work: novel, play, map, sonata▪ Form of expression: musical notation, musical sound▪ Form of carrier: sound cassette, videodisc

▪ Shouldn’t works and expressions have their own records with identifiers?

How does FRBR help us now?

▪ Some systems are using FRBR concepts (Open Library)

▪ We could derive new records with selected fields

▪ RDA Toolkit is organized by FRBR entities and relationships
