1 RDA Resource Description and Access
N.S. Harinarayana Associate Professor Department of Library and Information Science University of Mysore, Mysore This presentation is based on literature reviews and readings of various documents published either as hard copy or on the internet.

2 RDA: Resource Description and Access
The successor to AACR2 Released in 2010 Primarily web-based (RDA Toolkit), but also in but also in print form at a later stage Text is not read in a linear fashion Text is repeated whenever needed to support Hyperlink Based on concepts from FRBR (Functional Requirements for Bibliographic Records) JSC for the Revision of AACR decided that a change is needed for the current approach. The aim was to have guidelines that will cover description and access for digital as well as monograph resources. This should result in records that could be used in a variety of environments (digital and others). AACR was first published in 1978. JSC working with the editor of RDA is responsible for this new tool. JSC includes representatives of 6 major Anglo-American cataloguing communities 1- ALA, ACOC, BL, CCC, CILIP, LC.

3 RDA: Who is responsible?
Joint Steering Committee (JSC) American Library Association (ALA) Australian Committee on Cataloguing (ACOC) British Library (BL) Canadian Committee on Cataloguing (CCC) Chartered Institute of Library and Information Professionals (CILIP) Library of Congress (LC) Assisted by JSC Secretary and RDA Project Manager JSC reports to the Committee of Principals (CoP)

5 Adopting RDA Who is RDA for? What about training?
Libraries Metadata community Museums, archives, educators, publishers Dublin Core compatibility What about training? NLA will be working with various training agencies in Australia to make the materials available and accessible to all users If you are familiar with AACR2 you should find it easy to use RDA once you have familiarized yourself with its organization and vocabulary. Information on the key changes between AACR2 and RDA will be available to ease the transition, and since RDA will be a web-based tool it will be easy to navigate to the instructions you need. There are a couple of things that you can do in order to prepare for RDA. The first is to familiarize yourself with the concepts and vocabulary that is found in FRBR. The second is to keep up-to-date with RDA developments by reviewing drafts as they become available and monitoring comments about RDA on various list services.

6 New standard : why? Simplify rules
Encourage use as a content standard for metadata schema Encourage international applicability Goes past AACR2 in cataloguing digital resources Flexibility to accommodate newly emerging resources Support flexible catalogues It’s about recording data, not the presentation of this data Provide more consistency Rules will be applied independent of any particular syntax or structure Why do we even need a new cataloging standard? Briefly stated, [click] we now have an opportunity to simplify our cataloging code and [click] to establish it as a content standard for resource description for various metadata schema, and [click] to encourage its use worldwide. We need a new code [click] that will be more consistent across the various types of content and media, and that demonstrates the commonalities of different types of resources. [click] We want to address current problems with rules in AACR2, such as with GMDs (general material designators) and for cataloging digital materials, and [click] we want to change the approach to cataloging, to get back to more principle-based rules that build cataloger’s judgment and are simple to use. We also want a new standard that will encourage the application of the FRBR data model (Functional Requirements for Bibliographic records) and now also FRAD (Functional Requirements for Authority Data). –

7 New standard : why? – cont.
Emphasis on helping users by providing information they need to find, identify, select and obtain information resources Recognizes that libraries now operate in a digital web based environment. Support integration of library catalogue records with those produced by other metadata communities. Find materials corresponding to the search criteria Identify an item as being the one sought for (distinguish between two items) Select an item appropriate to the user’s needs and request Obtain the items by either lending, purchasing or access to an on-line resource. Helps users to understand the relationship between creators and works by clustering bibliographic records for different editions, translations or physical formats of a work. Goes past AACR2 in Identify and define the important things (entities) Identify and define the significant relationships between these entities Identify and define the attributes that characterize the entities

8 New standard : why? – cont.
Address current problems Principle-based To build cataloguer’s judgment Encourage application of FRBR/FRAD

9 BASIC CONCEPTS: Entity, Attribute, Relationship

10 WHAT IS ENTITY? Person

11 WHAT IS ENTITY? Place

12 WHAT IS ENTITY? Object

13 WHAT IS ENTITY? Event

14 ATTRIBUTES Descriptive properties possessed by each member of an entity set.

15 ENTITY SET/TYPE: ENTITY SET : STUDENT
Set of entities of the same type that share the same attributes. ENTITY SET : STUDENT Student A Student B Student C Student D

16 STUDENT A STUDENT B STUDENT C STUDENT D Mr. A Mr. B Mr. C Mr.D
ENTITY SET : STUDENT STUDENT A STUDENT B STUDENT C STUDENT D ENTITY SET : TEACHER Mr. A Mr. B Mr. C Mr.D

17 What is relationship? Meaningful association among several entities.

18 RELATIONSHIP SET/TYPE:
A set of relationships of the same type.

19 RELATIONSHIP SET : SUBJECT
ENTITY SET : STUDENT ENTITY SET : TEACHER Student A Mr. A Mr. B Student B Student C Mr. C

20 DEGREE OF RELATIONSHIP SET
The number of entity sets that participate in a relationship set.

21 RELATIONSHIP SET : SUBJECT
ENTITY SET : STUDENT ENTITY SET : TEACHER Student A Mr. A Mr. B Student B Student C Mr. C

22 TYPES OF ATTRIBUTES Single and composite: roll number is an example of single attribute as it can not be divided further. Name can be divided further into 3 parts consisting of first name , middle name , last name so it is an example of composite attribute.

23 TYPES OF ATTRIBUTES Single valued and multivalued: The attributes which have single value are single valued attributes such roll number. The attributes which has a set of values are called multivalued attributes. Such as any student can have more than 1 telephone number .

24 TYPES OF ATTRIBUTES Derived attribute: These attributes are derived from the existing attributes of entities. The value of a derived attribute is not stored , but computed when required.

25

26 TYPES OF ATTRIBUTES Descriptive attribute: The attribute of the relationship is called descriptive attribute.

27 Cardinality One to many Many to one One to one Many to many
It expresses the number of entities to which another entity can be associated via a relationship set. One to many Many to one One to one Many to many

28 ONE TO MANY A B a1 b1 b2 a2 a3 b3 a4 b4

29 MANY TO ONE b2 a1 a2 a5 b3 b1 a3 a4 A B

30 ONE TO ONE a1 a2 a3 a4 b4 b3 b2 b1 A B

31 MANY TO MANY a1 a3 a2 b4 b3 b2 b1 a4 A B

32 Key FRBR concepts FRBR Group 1 entities: FRBR Group 2 entities:
An entity relationship model FRBR Group 1 entities: Work Expression Manifestation Item FRBR Group 2 entities: Persons, corporate bodies FRBR user tasks: Find, Identify, Select, Obtain Main purpose is to develop a new standards for describing resources in particular for the digital world. There should be now a clear line of separation between recording of data and the presentation of data. The data recorded to describe a resource has to a) Identify the resource described b) select a resource hat is appropriate to the user’s requirements The actual book, CD, DVD  ITEM Title  MANIFESTATION Format, edition, translations (such as translation language, etc. )  EXPRESSION Who wrote this work? -- WORK Work : ID – Title – Date – etc. Expression ID Title – Form – Date – Language – etc. Manifestation ID – Title Statement of responsibility – Edition – Imprint – Form – Terms of availability – Mode of access, etc Item – ID – Provence – Location

35 Group 1 entities The “idea” of The Lord of the Rings: Work
e.g., the novel; the “movie”; the score. The realisation of The Lord of the Rings in one or more modes of expression: e.g. “English text”, “French translation”, “performance”, the director’s cut. Expression Manifestation The embodiment of The Lord of the Rings: e.g. CD audio book ISBN-13: ; or Audio Cassette  ISBN In the FRBR entity-relationships model, we have works and expressions – abstract entities of intellectual and artistic content. They are useful to identify in our bibliographic records, because we can use them to collocate or cluster together the things we collect and organize in libraries or display in our catalogs. When we record the intellectual or artistic content, we move from the abstract “work/expression” to a physical entity. As FRBR puts it, a manifestation is the physical embodiment of an expression of a work. In order to record something you have to put it on or in some container or carrier. So, manifestations appear in various “carriers,” such as books, periodicals, maps, sound recordings, films, CD-ROMs, DVDs, multimedia games, Web pages, etc. A manifestation represents all the physical objects that bear the same characteristics of intellectual content and physical form. In actuality, a manifestation is itself an abstract entity, but describes and represents physical entities, that is all the items that have the same content and carrier. When we create a bibliographic record, it typically represents a manifestation – that is, it can serve to represent any copy of that manifestation held in any library anywhere. One example or exemplar of a manifestation is called an item. Usually it is a single object, but sometimes it consists of more than one physical object, e.g., a monograph issued in 2 separately bound volumes or a sound recording on 3 separate CD’s. With an item entity, we are able to identify an individual copy of a manifestation and to describe its unique attributes - this may be information relevant to its circulation or preservation. Work, Exp, Man, It = Group 1 entities. This is all a bit abstract so let’s look at a specific example. CLICK The Lord of the rings is a work. Strictly there are several works called the Lord of the rings. The novel by J R.R Tolkien is the best known, perhaps. But is has been dramatised for radio, screen and stage, and interpreted in music. These creations are treated as distinct, but related works. Lord of the rings is also the title of a critical work by Jane Chance. The work has to be realised through a mode of expression. CLICK This could be textual. Different translations will be different expressions. Different productions of the musical would be different expressions. The extended cut is a different expression from the standard cinema release. Readings by different narrators would be different expressions. For anyone else to experience it, the expression has to be embodied in a some kind of carrier. Click. This is the manifestation. It could be a book , a DVD or, as in these examples a CD and Audio cassette. Click. My copy of the audio cassette is a specific example of one of these manifestations. When you catalogue, you infer the manifestation from a specific item Item An exemplar of a manifestation of, “The Lord of the Rings”, e.g.: My copy!. Group 1 entities Slide by Alan Danskin, British Library

36 FRBR Benefits Collocation Easier cataloging
Better organization of the catalogue Easier cataloging The ability to customize rules to suit a specific type of material. RDA will make it easier to identify basic instructions and ignore detailed instructions that are required for a more complex level of description The ability to retrieve rules for unfamiliar formats and save them as a workflow The ability to add users’ notes online and integrate rule interpretations and any institution policies Source: 16 (added Navita ) Writ points 2 & 3 under “Easier cataloguing” – it’s a one-stop shop affording easy reference to in-house policies, procedures and consultation of rule interpretations. VTLS was the first vendor of integrated library management systems to embrace FRBR and to test their vision of how to implement FRBR. In their presentations they explain their views of the benefits of applying FRBR to their system: They find that with FRBR, the principle of collocation is expressed in a much better way because you have a better and more easily understood organization to the catalog. It’s more intuitive to group the translations and editions and performances (expressions) and the various manifestations of those expressions under the work that is contained in those manifestations. Cataloging is easier with FRBR because the system can take advantage of the FRBR structure to automate the inheritance of identifying information – metadata from the highest levels of linked descriptions. FRBR Work and Expression records need only to be cataloged once. Right now, under traditional cataloging, catalogers have to repeat the Work and Expression elements every time they catalog a new edition of a work. Remember the scenario I showed you earlier of using the authority records for work and expression records with linked subject information….

37 FRBR Benefits Reduction in cataloging load Circulation
Work only catalogued once for all expressions of it Expression only cataloged once for all manifestations of it Item cataloging (already simple) remains the same Circulation Place holds at Work or Expression level rather than only at Manifestation level Source: 16 (added Navita ) VTLS was the first vendor of integrated library management systems to embrace FRBR and to test their vision of how to implement FRBR.

38 Critical Differences (Changes) Between AACR2 and RDA
Level of description Comprehensive description Analytical description Multilevel description Structure GMD/SMD [content: carrier or the physical format] Includes the carrier and type of media Music CD might be displayed as [music recording: CD audio], and Videocassette might be displayed as [moving image: video VHS] Map or Atlas on CD-ROM might be displayed as [cartographic resource: digital] Global edit and replace function will be able to map the existing GMD to its new value in the new field Comprehensive description – used to describe as whole the following type: a) resource issued as a single unit (eg. personal web site) b) resource issued in two or more parts simultaneously (e.g. 3 video cassettes issued as a set) c)resource issued in successive parts e.g. series of sheet maps a magazine published monthly, etc.) d) integrating resource (an updating loose leaf, web site that is updated on a periodic basis) Analytical descrip. Used to describe any of the following types: a) part contained within a larger resource as a single unit b) a part of a resource issued in successive parts (e.g. single vol, of a series c) part of an integrating resource one chapter in an administration manual issued as an updating loose-leaf vol.) Multilevel description : Any resource comprising two or more parts may be described using both a comprehensive description for the whole and analytical description

39 Critical Differences (Changes) Between AACR2 and RDA – cont.
Punctuation punctuation not integral BUT Can be mapped to existing MARC punctuation or any other Schema used (such as Dublin Core, .HTML, etc.) Retrospective cataloguing is not required as there will be no significant changes Compatible with AACR2 Instructions are not different but grouped and presented differently Retrospective adjustment will be minimal – only where rules on access point creation have changed Terminology

40 Further Changes: Rules for Access Points
Few abbreviations will be used in RDA Bible. O.T. After RDA: Bible. Old Testament Bible. O.T. Job After RDA: Bible. Job Rule of three Selections Lacking collective title There are likely to be a number of changes affecting the describing of religious works. These are the two that were identified in recent announcements. The first is part of a larger change. RDA will contain very few abbreviations. So Old Testament and New Testament will be written in full, when used to represent a work. The second change is to interposing elements. The testament will be removed Names of versions are used, as a present, as are dates. - Added Navita (replace “Now” with “After RDA”)

41 New Terminology AACR2 terms RDA terms Heading Access point
Authorized heading Main Entry Added Entry Authority control Uniform title RDA terms Access point Preferred Access point Primary Access point Secondary Access point Access point control Preferred title Name of the work (to include name of creator when applicable) We’re making an attempt to update the card catalog-based terminology that remains in AACR2. The AACR term "heading" of course comes from the text that was typed at the top or “head” of catalog card. We will be replacing this term with "access point.” So Main Entry and Added Entry headings will become "primary access point", and “secondary Access Point“ although we are still discussing these terms and will explore eliminating the need to declare any access point as “primary” other than for the purpose of naming a work. We’re also moving away from using the term “authority control” toward using “access point control”. The term Uniform Title is problematic because it actually has three different definitions in AACR2 (a standard way of naming the work, like Hamlet; a collective term, like “Selections”; or a unique title to distinguish among works with the same name, as for serials), so instead of using the term “uniform title”, we‘re proposing to use the term ’Preferred title’ which can be for either a work, an expression, or for when we want to cite the manifestation that contains the work and expression.

42 Mandatory Elements of Description
Title Statement of responsibility Edition Numbering Publisher, etc. Date of Publication Title proper of series Numbering within series Resource identifier Form of carrier Extent Scale of cartographic content Coordinates of cartographic content

43 RDA & MARC21 AACR2 and MARC 21 are two different standards designed for two different purposes. AACR2 is largely a content and display standard while MARC 21 is an encoding standard. RDA will contain guidelines for choosing and recording data to include in bibliographic and authority records. MARC 21 is one possible schema for encoding records created using RDA, but it will also be possible to encode records created using RDA in other schemas, such as MODS or Dublin Core. Spell out the acronym for MODS - Navita

44 Examples Harry Potter and the philosopher’s stone / J.K. Rowling. WORK

46 RDA Structure (Content)
Part one: Recording attributes of entities Part two: Recording relationships between entities The two major divisions of RDA are shown here. Part one roughly corresponds to most of AACR2 and Part two is added entries and some aspects of authority records (roughly) – added Navita

47 Attributes of Entities
Sect. 1. Recording attributes of manifestation and item Sect. 2. Recording attributes of work and expression Sect. 3. Recording attributes of person, family, and corporate body Sect. 4. Recording attributes of concept, object, event and place Anything in blue is not part of the first release of RDA. Essentially subject elements are not part of this release. – added Navita

48 Relationships between entities
- Internal relationships Sect. 5 – Primary relationships between a work/expressions/manifestations/items Sect. 6 – Relationships to persons, families or corporate bodies Sect. 7 – Subject relationships By internal relationships I mean relationships specific to the resource being described. So if I’m describing a sound recording. I will identify the work represented and the way that work is expressed as well as the manifestation of that expression. I will also want to include the names of people and corporate bodies associated with the recording. This might be the band that is performing, it could be the publisher, or a conductor or soloist. – added Navita

49 Relationships between entities
- External relationships Sect. 8 – Relationships between different works, expressions, manifestations and items Sect. 9 – Relationships between different persons, families, corporate bodies Sect. 10 –Relationships between concepts, objects, events and places These relationships go beyond the resource being described. If I’m describing a film that is based on a book, then I want to point out the connection between the film and book. That is a relationship between different works. – added Navita
