3. Quote from an early Metadata Practitioner, or is it déjà vu (all over again)
I can not help thinking that the golden age of cataloging is over, and the difficulties and discussions which have furnished an innocent pleasure to so many will interest them no more (Charles A. Cutter, published in 1904)
10/14/2018

4. Reference work relies on good catalog records
“The work of the reference department covers everything necessary to help the reader in his inquiries, including … expert aid in the use of the catalog.”
(Isadore Gilbert Mudge, 1936)
from Guide to reference books. 6th ed.
Chicago: American Library Association

5. What does this mean for us?
Cataloging=Metadata
Metadata can be harvested automatically by indexing robots
Metadata can be embedded in a digital object
Cataloging *is* a Public Service that increases the usefulness of information, it aids “resource description and discovery”  metadata helps people find the information they are looking for
10/14/2018

6. What does this mean for us? Cont.
Managing information (including access/rights management), and the long-term preservation of information (digital archiving)
Metadata is broader in scope than the traditional role of the technical services librarian/Cataloger
Increased collaboration
10/14/2018

7. Cataloging=Metadata
When we catalog a book, a serial, a map, etc., we describe that particular item using a metadata standard, MARC21, together with other rules, like AACR2. We create a catalog record.
The delivery platform, or mechanism for the catalog record is the LMS, the Library Management System (like our Orbis).
Cataloging requires special skills.
10/14/2018

8. Cataloging=Metadata
When we catalog digitized objects, an image of a picture, a manuscript, a finding aid, etc., we describe that particular item, using a metadata standard, DC, TEI, EAD, together with other standards, perhaps AACR2 (or its future version RDA). We create a metadata record.
The delivery platform, or mechanism for the metadata record is the Web, or some other digital management software. The LMS is not designed to deliver metadata records on the web, it is MARC-based.
Cataloging requires special skills.
10/14/2018

9. Sounds similar?
Yes, traditional library cataloging is a form of metadata, BUT THE DIFFERENCE IS IN TECHNOLOGY!
The technical environment has completely changed from the MARC-based system to the Internet, to Web delivery, when applying non-MARC XML-based metadata standards.
Cataloging principles remain very similar whether applying the MARC21 metadata standard or other non- MARC metadata standards.
The new technology brings new sets of rules with itself.
10/14/2018

10. The library’s goal is:
To provide simultaneous access to its traditional library collections as well as its digital collections, in a seamless, integrated manner [searching across multiple data types and databases].
10/14/2018

11. If we didn’t catalog………….
For the user it would mean…………………
10/14/2018

12. Metadata chaos
10/14/2018

13. Metadata is:
A simple and classic definition: data about data or information about information
More accurately: structured data or information about an information resource
Used differently in different user communities according to their needs
Machine understandable information designed to be indexed and retrieved on the Web –not by online catalogs
In libraries a formal scheme used to describe an object/resource (including digital)
MARC21 *is* metadata (ISO 2709) - an international standard used for bibliographic data in library catalogs. It can also be used to describe digital objects (it has limitations)
10/14/2018

14. Metadata does:
Through cataloging – facilitates discovery of relevant information
Facilitates interoperability
Facilitates resource discovery. Same as in a quality catalog record!
10/14/2018

15. A metadata record is…
A file of information, usually presented as an XML document
It captures the basic characteristics of a data or information resource – structured data about data
(same concept as in a MARC catalog record)
Data elements are defined for a metadata record by the rules of a particular standard that is applied
Created and maintained
10/14/2018

16. Different metadata standards for different folks
DC – Dublin Core (ISO15386) :the “CIP” of the digital world – simple
DC can be expressed in XML (RDF/XML) Resource Description Framework
(RDF – a data model designed to integrate multiple metadata schemes)
QDC – Qualified Dublin Core – more sophisticated than simple DC
EAD – Encoded Archival Description created to display finding aids on the web
TEI – Text Encoding Initiative for electronic text (Lite version, too)
10/14/2018

17. Different metadata standards for different folks cont..
MathML – Mathematical Markup Language (an application of XML), represents mathematical symbols and formulae
FGDC – Federal Geographic Data Committee -for maps (although MARC can be used to describe a map, it is not designed to convey complex numeric information for GIS – Geographic Information Systems - data sets)
Onix – Online Information Exchange for book industry, bibliographic, trade used by publishers, an international standard, XML based, libraries may receive Onix records in the future
10/14/2018

18. Simple Dublin Core: DC (can be embedded in the head of an HTML document)
The Simple Dublin Core Metadata Element Set (DCMES) consists of metadata elements
Title Type
Creator Format
Subject Identifier
Description Source
Publisher Language
Contributor Relation
Date Coverage
Rights
Each Dublin Core element is optional and may be repeated. The Dublin Core Metadata Initiative (DCMI) has established standard ways to refine elements and encourage the use of encoding and vocabulary schemes. There is no prescribed order in Dublin Core for presenting or using the elements.
10/14/2018

19. Qualified Dublin Core: QDC
Refines the 15 DC elements, making them more specific
Some of these are: Title refinement: Alternative
Date refinement: Created
Date.Issued Date.Modified
Format.Extent
Relation refined: Is Version Of
Is Part Of
Is Format Of
QDC includes recommended encoding schemes which help in the interpretation of the element value (eg LCSH)
10/14/2018

20. XML – Extensible Markup Language
Is not a metadata format itself, but can be used to express metadata formats
a language container: a ‘metalanguage’
a W3C – WWW Consortium standard
XML tags have no predefined meaning.
XML is a syntax for data structure standard creation
A flexible text format, important for data exchange on the Web
Unlike HTML it does not specify how to display data on the Web (bold, color, etc). That is done through XSLT – Extensive Stylesheet Language transformations.
10/14/2018

21. Example of a simple XML record
<?xml version="1.0" encoding="ISO " ?> <!-- Edited with XML Spy v2006 (   -->
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>
10/14/2018

22. Same XML record with an error
The XML record is transformed using XSLT – a stylesheet language for XML - to display it on the Web. The record has to be well formed and has to be validated, otherwise it can’t be displayed….
10/14/2018

23. Mappings and crosswalks between metadata formats
Crosswalks facilitate moving metadata from one scheme to another; mapping of the data elements, semantics, and syntax.
They facilitate interoperability and exchange of metadata.
Like translating from one language to another
Examples at :
and
Difficulties betweens crosswalks of different metadata formats (field definitions)
Best practices for standardized records
10/14/2018

24. One size does not fit all
No single standard is suitable for all purposes
Proliferation of standards
Obvious advantages exist to having a single standard for cataloging both digital and non-digital materials
10/14/2018

25. Searching empowered by metadata
Through analysis of resource content
Appropriate thesauri
Designated fields for data exchange and migration
Richer than keyword
10/14/2018

26. METADATA TYPES:
Descriptive (such as author, title, abstract); it is the most standardized -- MARC, MODS, DC
Structural (such as how resource is put together, pages, chapters) –METS (Metadata Encoding and Transmission Standard), XML
Administrative (such as technical information, file type, track history of creation and changes, access/rights management and intellectual property, preservation metadata to archive the resource) –ERMI (Electronic Resource Management Initiative), PREMIS (PREservation Metadata Implementation Strategies)
10/14/2018

27. Descriptive metadata type/format: MARC21
Machine Readable Cataloging record, an international communication standard, ISO 2709
Originally designed in the late 1960’s to aid in the transfer of bibliographic data onto magnetic tape, and to replace the printed catalog cards with electronic form
MARC is not a cataloging code
A carrier for bibliographic information, such as titles, names, subjects, notes, publication information, and physical descriptions of objects
10/14/2018

28. MARC21
Standard for exchanging bibliographic, holdings and other data between libraries.
Allows for data elements for different types of material: a foundation that most library catalogs are built on.
10/14/2018

29. Catalog this! Using MARC21 formats!
Books
Continuing resources (serials)
Integrating resources
Maps
Music (scores)
Sound recordings
Visual materials
Electronic resources
Mixed materials
10/14/2018

30. Levels of description: full, minimal and in-between
Describe a book
Describe a collection, a whole set, separate volumes in the set
Describe a photograph
Describe a chapter in a book
Describe a video
Describe an electronic resource, a digital object
10/14/2018

31. Describing information on the web:
MARC is designed for use in library catalogs, by automated library systems, not for use on the web
MARC can be transformed to be displayed on the web: MARCXML, MODS
To describe other objects on the web: use Dublin Core metadata standard, use XML, use TEI for text, EAD for digital finding aids, etc
10/14/2018

32. MARCXML A framework for working with MARC data in an XML environment
Complete MARC record is represented in XML, no loss of data
Can convert back to MARC easily, no loss of data
All MARC formats (book, map, music, etc) are supported
Customizable for local solutions
10/14/2018

36. MARCXML: Example Where MARC exists within the world of XML
-XML - just a different way of encoding MARC
Tags are preserved in their semantics
1:1 mapping
No loss of data during conversion
Extensible – can be customized
10/14/2018

37. MODS: Metadata Objects Description Schema
XML-based descriptive metadata standard
A subset of data elements are derived from MARC21, uses language-based tags
Highly compatible with MARC21, (but not a MARC replacement)
Richer than Dublin Core
Uses natural language tags rather than numeric tags
Accommodates special requirements for digital resources
10/14/2018

38. MARC limitations in the digital environment
Lack of expandability due to rigorous record formats (goes back to the production of printed card catalog cards)
Weaknesses in describing bibliographic attributes of digitized resources
Incompatible with other MARC formats
Bibliographic relationships are not easily represented
Can’t be processed directly by web applications
10/14/2018

39. So, is MARC still needed? YES!
But it’s one of the metadata standards we can use – not the only one
OPAC is not necessarily the “center of discovery”
Can be retooled, repurposed, transformed…
Still the best way to describe resources for discovery, identification and retrieval in traditional library catalogs (like Voyager)
10/14/2018

40. MARC21 standards: MARC21 Format for Bibliographic Data
MARC21 Format for Authority Data
MARC21 Format for Holdings Data
MARC21 Format for Classification Data
MARC21 Format for Community Data
10/14/2018

41. Bibliographic record type:
A carrier primarily for bibliographic information about printed or manuscript textual materials, maps, music, serials, visual materials, electronic resources
..or any source of information which can be represented in a catalog record
10/14/2018

42. Authority records:
Are a carrier for information concerning the authorized forms of names, titles, subjects (and subject divisions) to be used in constructing ACCESS POINTS
Describe names and terms which need to be standardized for optimal retrieval of data
Include personal, corporate, geographic names and controlled vocabularies
10/14/2018

43. Value of Authority control
Most efficient and effective mechanism for optimal retrieval of information
Without authority control, access to information can be severely compromised
10/14/2018

44. Holdings records:
Are a carrier for holdings information for three types of bibliographic items:
Single-part
Multipart
Serial (may include copy-specific information, information needed for local processing, maintenance, preservation or version information)
Indicate the number and locations of copies of a resource cataloged in the bibliographic record
10/14/2018

45. Classification records:
A carrier for information about classification numbers and the captions associated with them that are formulated according to a specific authoritative classification scheme
10/14/2018

46. Community Information records:
A carrier for descriptions of non-bibliographic resources that fulfill the information needs of a community.
10/14/2018

47. MARC
In the beginning different flavors….MARC, USMARC, CANMARC, UKMARC, AUSMARC…harmonization  MARC21
Information is stored in a consistent form
Data is manipulated by a computer
Allows for communication between systems
Accommodates extensive data elements
A highly complex communication or data structure standard that provides concise data management
10/14/2018

48. MARC has three components:
Record structure (based ISO2709 and ANSI Z39.2)
Content designation – these are the codes used to tag elements of data within a MARC record
Data content of a record – the object we are coding, a book, a map, etc. according to data formatting standards (AACR, LCSH, LC Classification, DDC, etc.)
10/14/2018

49. MARC supporting documentation
Character sets:
- MARC-8 (8-bit encoding)
- UCS/UNICODE UTF-8 (8/16 bit encoding)
- 15,000+ characters
- Latin, Cyrillic, Hebrew, Arabic, CJK
Code lists: countries, geographical, languages, sources, relators
10/14/2018

50. We’ve got standards!
Standards are: a set of rules and guidelines that provide a common framework
Aid interoperability
ISO – International Organization for Standardization and NISO, W3C, DLF – Digital Library Federation: METS – Metadata Encoding and Transmission Standard: OAI – Open Archives Initiative
ISBN, ISSN, ISMN (music) are ISO standards
ISO/IEC – IT Metadata Registries (MDR)
ISO Format for information exchange
10/14/2018

51. Cataloging standards
Content standards: AACR (Anglo-American Cataloging Rules) –now in it’s 2nd ed. (AACR2)
An international data content standard used by approx. 56 countries around the world for all types of materials collected by libraries. It standardizes the use of MARC
Cataloging rules have gone through many iterations responding to changing needs, first ed. In 1967, nd ed.
Rules in AACR2 cover the description of library materials and also the provision of access points
10/14/2018

52. Change is the only constant…
RDA – Resource Description and Access (not AACR3)
“RDA is being developed as a new standard for resource description and access designed for the digital world” – JSC – to be published in 2007
Will cover all types of content and media
Aligned with FRBR – a conceptual model for how bibliographic databases might be structured (Functional Requirement for Bibliographic Records) and FRAR (Functional Requirement for Authority Records)
FRBR identifies and defines: (1) entities of interest to users of bibliographic records; (2) their attributes; and (3) the relationships that operate between them; work (intellectual) being the top hierarchy, then expression, manifestation, and the item
Separates recording of data and the presentation of data
10/14/2018

53. Some other content standards
DACS - Describing Archives: A Content Standard – (replaces APPM- Archives, Personal Papers, and Manuscripts ). DACS extends Ch. 4 of AACR2.
-- Specific rules for describing archives and illustrates how these rules might be implemented in MARC and EAD format. It includes crosswalks to these and other standards.
-- can be used to describe archival materials at any level of specificity, from the collection to the item level.
DCRB – Descriptive Cataloging of Rare Books (concordance of rules between DCRB and AACR2)
FGDC Content standard
10/14/2018

54. ISBD standard
International Standard Bibliographic Descriptions standard - specifies the requirements (a set of rules) for description and identification of information resources
These rules organize the bibliographic description of an item in Areas such as: title, statement of responsibility, edition, publication, physical description, series, notes, standard numbers (ISBN, ISSN)
It is sequential: title must come first, then author..
10/14/2018

55. ISBD punctuation Cataloging rules dictate it
Space / space precedes statement of responsibility, $c in title info (tagged 245)
245 04$aThe plays of Oscar Wilde /$cAlan Bird.
(space before $c is system supplied in many software programs)
Limited space originally on 3x5 catalog cards, ISBD was governed by saving space
These rules are still useful for computer screen displays
10/14/2018

56. Classification standards
Systems of organizing and coding library materials according to their related subject matters
Taxonomic classification – placing the object into a category or a subject index,
List of subject headings – controlled vocabularies eg, LCSH – an integral part of bibliographic control and improved searching accuracy
Classification schemes - eg LC, DDC
Assignment of a class number (according to rules)
10/14/2018

57. Library Management Systems
also called Integrated Library Systems
Built on Database technology (Oracle RDBMS - relational database: all data is stored and retrieved based on relations); and GUI (Graphical User Interface: displays windows, icons through a web browser, ) technology
Based on MARC, built on standards, utilizes the MARC format for storage of data
Keep track of library materials
Have different clients, or modules: Acquisitions, Cataloging, Circulation (keeps track of overdue books), OPAC
Through OPAC can reserve copies online through a web interface
Endeavor:Voyager is an example – other major ones: Ex Libris:Aleph, Innovative: Millennium, Koha ILS, the only open source library software available (
10/14/2018

58. MARC: the pillar of the bibliographic record
Computers can interpret the data in the catalog record
Cataloging staff create and edit MARC records
Other staff working with MARC21 records need to know how to read, understand, use and interpret the MARC record.
Different kinds of bibliographic records
10/14/2018

59. Cataloging – where it all comes together: deciding exactly what it is we are cataloging
Searching locally and the utilities for copy – no match: create original record
Analyzing the resource
Using AACR we determine the information we have to provide for the type of material we are cataloging
Subject analysis and classification
Bibliographic control
Coding information into the format required by the MARC standards
(no surprise! If we didn’t code it, you won’t find it!)
10/14/2018

60. Copy Cataloging or adaptive cataloging:
Searching for copy
Finding exact match – still might want to edit
No exact match, but variant copy – clone record (different edition, etc) – remove all information that does not apply to your resource in hand
Follow rules and local procedures for editing
(If you didn’t add it, you won’t find it!)
10/14/2018

61. Input standards
LC has its established input standard for entering bibliographic data in MARC records – Yale practice is to follow LC (in most cases)
OCLC also has its own input standard if using OCLC to directly input records
Complicated by the varying levels of completeness (fullest, brief, etc) of the record
LC:
OCLC:
10/14/2018

62. Knowledge of MARC tells you:
What data elements your database contains
How they are indexed – if at all
How they can be searched
How they are displayed – if at all
10/14/2018

63. MARC record format:
Leader: first 24 characters of the record, defines parameters for processing the record
Directory: entries that contain the tag used in variable fields, they are constructed by the computer from the bibliographic record. In communication format the fields are not preceded by tags.
Variable field: variable control field: 00X, fixed length data elements, and variable data field: indicators and subfield codes
10/14/2018

65. The Leader:
24 positions from 00 to 23 that provides information to the computer for the processing of the record.
10/14/2018

66. Leader: Encoding level 00/17 example
Blank (#) Full level – LC standard
1 Full level material not examined
2 Less than full level, material not examined
3 abbreviated level
4 core level
5 partial (preliminary) level

I Full level – OCLC standard
K Minimal level – OCLC standard
Codes indicate the fullness of the bibliographic information in the record.
10/14/2018

67. Parts of a MARC record Fields and tags Indicators Delimiters
Fixed fields
Variable fields
10/14/2018

68. Fields subfields and delimiters:
Fields – can be mandatory, required if applicable or optional
Can also be repeatable (subfields also)
Subfields are marked by subfield codes and delimiters (the smallest logical units in a variable field) organize the information within a given field – eg $a Money : $b a necessary evil – where $b represents the subtitle. Subfields codes are letters or numbers (eg. 650 $2 example: $2 Source of heading or term: 650 \7
Subfields are specific to each type of field and are controlled by content standards
delimiters can be represented by different characters: double dagger, a $, a # sign
Each field is represented by a 3-digit tag, which identifies the field – eg 245 represents the title information
OPAC labels display names of the field – they are customizable
10/14/2018

69. Indicators
Each tag is followed by two indicators, their values may range from 0-9
Some fields use both indicators
Some fields use one character position only
Some fields use none, the position is blank and is “undefined”
Supply information about the field for indexing
10/14/2018

70. Functions of Indicators
Nonfiling characters $a The Adventures of Safety Frog. $p Fire safety $h [videorecording] / $c Century 21 Video, Inc. VERY IMPORTANT!
Control of notes and added entries $a Fire safety $h [videorecording]
Display constant control – eg. first indicator display a note or not
Source of information/thesaurus – eg. LCSH 650 \0 if limit by searching only LCSH
Further qualification of field content
10/14/2018

71. Control fields
005 – system created, can tell you date and time record was last saved, down to a tenth of a second – you can see if you saved it recently or not
Note that each 006 represents a material type (tabs in Voyager)
10/14/2018

72. 007 - Physical Description Fixed Field:
Contains special information about the physical characteristics in a coded form. The information may represent the whole item or parts of an item such as accompanying material
10/14/2018

73. 007 example (from OCLC manual):
For example, you are cataloging a kit that has: 25 activity cards, 60 artifacts, 3 books, 3 filmstrips, 1 learning guide, 25 study prints, 2 sound cassettes and 14 transparencies. The activity cards, filmstrips, study prints and transparencies share the same physical characteristics, respectively.
Use a separate 007 field for each group of materials (i.e., an 007 for the 25 activity cards, an 007 for the 3 filmstrips, etc.). Since the sound cassettes are not associated with projected material, use a separate 007 field for the sound cassettes.
007k ‡b o ‡d c ‡e o007g ‡b o ‡d u ‡e j ‡h f007k ‡b f ‡d m ‡e o ‡f c 007s ‡b s ‡d l ‡e u ‡f n ‡g j ‡h l ‡i c ‡n e007g ‡b t ‡d c ‡e j ‡h v
activity cards, 60 artifacts, 3 books, 3 filmstrips, 1 learning guide, 25 study prints, 2 sound cassettes, 14 transparencies; ‡c in container 30 x 25 x 13 cm.
10/14/2018

74. 008 – Fixed-length data elements
Otherwise known as the “Fixed Field Codes”
Contains 40 character positions (00-39) that provide coded information about the record as a whole and about special bibliographic aspects of the item being cataloged. These coded data elements are potentially useful for retrieval and data management purposes.
10/14/2018

75. Example of 008 field in OCLC:
10/14/2018

76. Same 008 display (fixed field) in Voyager:
Bib#
10/14/2018

77. Fixed fields are used in “limits” of the OPAC
Limit feature allows users to restrict results of their searches by:
Language (character position 35-37)
Collection
Date
Medium
Item Type
(note:”More limits” must be set BEFORE entering search terms)
10/14/2018

78. 01X-04X – Number and code fields
010 – LC Control Number or LCCN, since 2001 ‘normalized’, pre-2001 had prefixes, like sn now entered as $a sn Invalid LCCNs are entered in $z of the 010 field.
020 – ISBN
022 – ISSN
024 – Other standard identifiers, like a UPC: Universal Product Code barcode
028 – Publisher number, (identifies videorecordings, printed music, sound recordings, etc)
10/14/2018

79. 01X-04X – Number and code fields cont…
035 – System control number, like OCLC $a (OCoLC) (8 digits)
037 – Source of Acquisition (mostly used for subscription information for serials)
040 – Cataloging source – MARC code that identifies the institution that created the record in $a YUS, $c that input record, $d edited the record.
041 – Language codes, when 008 is not enough, for more than one language: eg. $aeng$afre$ager
