  1. INLS 520 Information Organization INLS 520 – Fall 2007 Erik Mitchell

  2. Review • Metadata models • DC, METS • Metadata Standards • Dublin core / qdc • Encoding Schemes • HTML, XML, MARC… • Advanced metadata concepts • Schemas, application profiles INLS 520 – Fall 2007 Erik Mitchell

  3. Today • Core Skills for Library/IS types • MARC Overview • Encoding • Related Standards • Exercise • RDF Introduction (brief) • Introduction to programming (brief) INLS 520 – Fall 2007 Erik Mitchell

  4. Discussion • Read assigned posting from NGC4LIB discussion group. • Share in group & think about the following questions: • What are the core skills that an information organization professional should have? • What is the relationship of Information organization to these “core skills?” INLS 520 – Fall 2007 Erik Mitchell

  5. Anatomy of a bibliographic record INLS 520 – Fall 2007 Erik Mitchell

  6. MARC value standards • Fields & Values • Fields, Indicators, Subfields • More information from OCLC • Content and encoding standards • AACR2 • RDA • Development started in 2004, slated for release in 2009 • An enjoyable article on the development of RDA INLS 520 – Fall 2007 Erik Mitchell

  7. How to enter a title into a MARC record • AACR2 • Transcribe title exactly according to spelling but not necessarily punctuation/capitalization. • If an alternative title is present, precede it by a comma following the regular title • Use a General Material Designation in brackets [] • MARC Standard • Use 245 field – indicates Main title • Indicator 2 – Number of non-filing characters (leading articles) • Subfield a – main title • Subfield b – remainder of title • Subfield h – General Material Designation in brackets [] INLS 520 – Fall 2007 Erik Mitchell

  8. MARC metadata • Definition • Machine Readable Catalog Record • Combination of content, value, and encoding standard • History • Created by Henriette Avram in 1968 • Managed by the Library of Congress INLS 520 – Fall 2007 Erik Mitchell

  9. MARC metadata • The encoding standard • Variable length record • Set leader defines position of fields in record • Fixed fields in leader codifies format information • Variable length fields provide descriptive content • Examples • System ready example record (LC) • Uses of MARC fields by OCLC • More information • More information from LC INLS 520 – Fall 2007 Erik Mitchell

  21. MARC Exercises • Introduction to MARCEdit • If you can’t use MARCEdit – use a text editor & follow this standard: • =245 04 $a content $b more content • Tour of the application • Exercise 1 – create a MARC record • Exercise 2 – decompile/compile MARC records, batch edit INLS 520 – Fall 2007 Erik Mitchell

  22. FRBR Model http://fictionfinder.oclc.org/ http//worldcat.org http://www.frbr.org http://www.ifla.org/ INLS 520 – Fall 2007 Erik Mitchell

  23. FRBR background • Work/item • C.A. Cutter (1890) • Notion of a work • S. R. Ranganathan (1930-late 1960) • Intellectual entity – expressed thought • Physical entity – embodies thought • P. Wilson • Intellectual entity – work • Subject metadata • Physical entity – item • Selected descriptive metadata INLS 520 – Fall 2007 Erik Mitchell Adapted from Jane Greenberg

  24. FRBR components • Work • distinct intellectual or artistic creation • Expression • intellectual or artistic realization of a work • Manifestation • physical embodiment of an expression of a work • Item • a single exemplar of a manifestation INLS 520 – Fall 2007 Erik Mitchell Adapted from Jane Greenberg

  25. FRBR Example • Rolling Stones’ IT'S ONLY ROCK-N –ROLL(1974) (work) • Group’s performance recorded for the album (Expression) • Recording released in 1974 by MCA Records on tape cassette (Manifestation) • Recording released in 1974 by MCA Records on compact disc (Manifestation) • Sheet music released in 1992 (?) INLS 520 – Fall 2007 Erik Mitchell Adapted from Jane Greenberg

  27. FRBR Algorithm (1) • Process • Extract Author • Construct Authority author entry from100, 400 using subfields and 008 data to limit • Extract Title • Construct Authority title entry from 130, 240, 245, etc. Normalize using NACO • Combine these two authorities to create a unique Work identifier • <author>Mitchell, Margaret</author><title>Gone with the wind</title> INLS 520 – Fall 2007 Erik Mitchell

  28. FRBR Algorithm (2) • Results from a sample extraction (From FRBR doc) • <author>/<title> (75.97%) • <uniform title> (1.34 %) • /<title>/[one or more <name>] (17.35%) • /<title>/<control number> (5.34%) • http://www.oclc.org/research/software/frbr/frbr_workset_algorithm.pdf INLS 520 – Fall 2007 Erik Mitchell

  29. Warwick Framework • Origins / Definition • Beginnings: Came out of DC discussions in 1995/6 • Goal: to promote interoperability, define context of the DC metadata, come up with a way of ‘contextualizing’ DC description • Definition: A general model that describes the various parts of a complex object, including the various categories of metadata.-http://www.cs.cornell.edu/wya/DigLib/MS1999/glossary.html • Components • Container • Package • Metadata set • Indirect link • Another container INLS 520 – Fall 2007 Erik Mitchell

  30. Resource Description Framework • Origins • PICS (Platform for Internet Content Selection) • Warwick framework • Initial goal was to code metadata for the web • Definition: • A data model • A set of “statements” about a “resource” • RDF Triple: Description = Resource with Value INLS 520 – Fall 2007 Erik Mitchell

  31. RDF Example • A resource is a uniquely identifiable thing (URI) • Properties are given context (Property Type) INLS 520 – Fall 2007 Erik Mitchell From Miller, 1998

  32. RDF Model Author Webpage: http://ils.unc.edu “Abe Crystal” (Value) Object (Resource) Subject (Property type) Predicate • “The author of the SILS Webpage is Abe Crystal” http://ils.unc.edu has a creator with name Abe Crystal • A literal, a triple, a statement From Greenberg INLS 520 – Fall 2007 Erik Mitchell

  33. How is RDF different? • RDF is a descriptive model that • Allows variable contextualized description • Deconstructs the descriptive process • Allows more granular automated processing of data • Uses exact markup to indicate the context of values (namespaces, schemas) • A simple Example INLS 520 – Fall 2007 Erik Mitchell

  34. Encoding RDF in XML <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dcterms="http://purl.org/dc/terms/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"> <rdf:Description rdf:about="http://purl.org/dc/elements/1.1/">   <dc:title>The Hang: The Island of Black Jeans</dc:title>   <dc:creator>SAKI KNAFO</dc:creator>   <dc:identifier>http://www.stuff.com</dc:identifier>   <dc:date>Sun, 16 Sep 2007 01:04:40 GMT</dc:date>   <dc:description>descriptive content</dc:description>   </rdf:Description> </rdf:RDF> INLS 520 – Fall 2007 Erik Mitchell

  36. DC in RDF • Expressing Simple Dublin Core in RDF/XML (Beckett, et al., 2002) • http://dublincore.org/documents/dcmes-xml/ • *note, remember, you cannot do qualification with this recommendation. • Expressing Qualified Dublin Core in RDF / XML (Kokkelink & Schwänzl, 2002) • http://dublincore.org/documents/2002/04/14/dcq-rdf-xml/ INLS 520 – Fall 2007 Erik Mitchell

  37. Programming 101 • What is a program? • What concepts do we need to understand? • Is XSL a programming language? INLS 520 – Fall 2007 Erik Mitchell

  38. Programming 101 • Definition: • “the act of creating software or some other set of instructions for a computer.” [1] • Examples • Dynamic web sites • Compiled applications (like Firefox) • Small applications that perform a specific task (such as transform metadata) INLS 520 – Fall 2007 Erik Mitchell

  39. Definitions • Programming Language • “A formal language used to write instructions that can be translated into machine language and then executed by a computer.” (definitions) • Scripting Language • Run-time (does not require compilation) • Restricted context (requires a specific environment) • Functional / Object oriented • Definitions • Compiler / Interpreter • A program that builds and executes a program. Compilers create a self-executable file, interpreters read a text script at run-time

  40. Programming approaches • Logical/structural programming • Stream of consciousness • Starts at line 1 • Procedural programming • Uses functions, sub-functions, subroutines • Encapsulation, modularization • Object-oriented programming • Further encapsulation • Uses concepts of inheritance, modularity

  41. Flow of Document Models What is the relationship of the data model to the intended document use in the four following document examples? INLS 520 – Fall 2007 Erik Mitchell

  42. The programming process • Analyze the problem • What do you want your program to do? • What are your users expecting, what data do you have? • Plan program flow/logic • What steps need to occur, in what order? • Useful tools include Step-Form, flowcharts, and pseudocode • Code the program • Create variables, routines, functions • Compile/run the program • Test, verify • Release

  43. Programming 101 - Concepts • General structure • Programs have a ‘flow’ to them • Programs use functions, algorithms, and objects to compartmentalize operations • Programs follow a specific syntax (their own document model) • Programs operate in specific environments (compiled platforms, run-time platforms) INLS 520 – Fall 2007 Erik Mitchell

  44. Programming 101 – Concepts • Control Structures • Looping (while) • Decision making (if) • Variables • Store information for use/reuse • A simple varaible is name=value INLS 520 – Fall 2007 Erik Mitchell

  45. Programming 101 - XSL • Is XSL programming? • What can we use XSL for? • Why are we covering it here? INLS 520 – Fall 2007 Erik Mitchell

  46. XSL Overview • Extensible Stylesheet Language • Components • Defined XML standard which is used in conjunction with a transformation engine to transform XML data • Xquery/Xpath • Capabilities, limitations • Document processing • Semi-functional programming language

  47. XSL Introduction • Styling • XSL - eXtensible Style Language • Querying • XPath • XQuery • XPointer • XLink • Good resources for reference • http://www.w3schools.com/xsl/default.asp • http://www.w3.org/Style/XSL/ • http://www.w3schools.com/css/default.asp • http://www.csstutorial.net/
