Week three reading:Metadata
Setting the Stage - Gilliland
-Metadata:data about data
-as information resources increase put online by general public- metadata considerations no longer solely the province of information professionals
-increasingly important to understanding critical roles of different types of metadata to ensure accessibility, authority, inter operable, scalability, preserve cultural heritage information and record keeping systems
*-metadata is the sum total of what one can say about any information object at any level of aggregation
-all information objects have 3 features which can be and should be reflected through metadata
-content:what the object contains or is about and is intrinsic to an information object
-context:who what where when why and how aspects associated with the objects creation and is extrinsic to an information object
-structure:formal notes of association within or among individual information objects and can be intristic, extrinsic or both
-to professionals metadata is the value added information that they create to arrange, describe, track and otehrwise enhance access to information objects
-mark-up languages (HTML/XML) provide standardize ways to structure and express these standards for machine processing
-data structure standards:categories and containers ie:MARC
-data value standards:controlled vocabularies ie:Library of Congress subject headings
-data content standards: cataloging rules and codes ie:AARC/RDA
-data format/technical interchange standards: metadata standards for machine readable ie:MARC21
-Metadata categories:
-administrative:managing collection
-descriptive: used to identify collection
-preservation: preserve and predict access of collection
-use: level and type of use of collection
-technical: how system functions or how metadata behaves
-Primary function of metadata :
-creation, multi version, re-use and contextualization of information objects
-validation
-search and retrieval
-utilization and preservation
-disposition
FYI:
-metadata des not have to be digitalized
-relates to more than the description of object
-can come from a variety of sources
-continues to accrue defining information
-distinction between what constitutes data and what constitutes metadata can be fluid and may depend on how one wishes to use a certain information object
-Why is metadata important?
-increase inaccessibility
-retention to context
-expanding use
-learning metadata for search objects
-mutli-versions
-legal issues
-preservation
An Overview of the Dublin Core Data Model-Miller
-DCMI is an international effort designed to foster census across disciplines for the discovery-oriented description of diverse resources in an electronic environment
-DCMI Requirements:
internationalization
modularization/extensibility
element identity
semantic refinement
indentification of encoding scheme
specification of controlled vocabulary
-there are resources in the world that we would like to describe
-these resources have properties associate with them
-properties are a specific type of resource
-classes of objects are specific type of resource
Addressing functional requirements
-element identity: very important that both writer and reader understand the same meaning for term
-modality/extensibility: name space are simply away to tie a specific use of a word or context to the dictionary/scheme where the intended definition is found
-semantic refinements: RDF processor recognizes the sub-type relationship that exists between two semantic declarations, ie: Michelangelo- as painter and as contributor to Sistine Chapel
-Compound Values: resources may be combined in various descriptive ways, ie: a person may an a name, email, affiliation and also may have various properties characteristics such as creator, publisher, subject associated with them
Working with Endnote
Endnote is a bibliographic software program that is used for literature searches, to develop personal libraries of references and create and format citations for papers/publishing
Uses for Endnote:
-to import citation from saved literature Sachs
-develop a personal library of references
-create and format citation for papers and publications

Wikipedia:Computer Hardware
-collection of physical elements that comprise a computer system
-history:
-1800s-punch card technology
-1880s-punch card data storage, ie:IBM, US census
-1920s-desktop calculating
-1940s-mechanical and electrical analog computers, Stibitz digital computing in binary form,EUVAC
-1950s-IBM 701-first mainframe computer, Wilkes invented micro programming, IBM introduces first disk drive, network to network intercommunication
-1960s-Intel single chip micro processing
-1970s-first person computer with floppy disk
-Mainframe computers aka Big Iron: are powerful computers used by corporate and government organizations for critical applications, bulk data processing, enterprise resource planning (?) and transaction processing
-Mainframe refers to the large cabinets that housed the central processing units and main memory of early computers
-Mainframes reference the difference between high-end commercial machines from less powerful units
-Minicomputers in a class of multi-user computers, class of mid range computers, ie: SPARC and Sun Microsystems
-Personal Computers: general purpose computers used by individuals, intended to be operated directly by an end-user without intervening computer operator.
Wikipedia:Computer Software
-Collection of computer programs and data
-Provides instruction to the tell the computer what to do and how to do it
-Refers to to one or more computer programs and data held in storage of the computer for some purpose
-Program software preforms the function of the program it implements either by direct instruction or serving and input to another piece of of software
-Until 1980s software was bundled with hardware
1985 IBM releases DOS source for free...leading to Microsoft
USER<-->APPLICATION<-->OPERATING SYSTEM-->HARDWARE
Digitization-Is It Worth It? Lee
-Digitization- the conversation of analog media to digital form
-Creation of a still digital facsimile of a source item
-Real unit cost of digitalizing an item could be 3 - 4x the amount estimated
-Benefits of digitization:increased access, preservation, meeting an institutes strategic goals (?)
-Digitization liberates the document from the constraints of traditional access methods
-ROI evaluation cost of launching digitization project vs. resources towards traditional collection development
NYT - European Library Face Problem with Digitization - Carvajal
-Problem faced by European Digital Library is lack of funds to digitalized everything it wants
-What will the business model look like to pair public institutions needs and service with private corporate backing for online digitalizing access?
-How will it be sustainable?
-Goal of the European digitization project is to create a balance to Googles massive corporate digitialization plans
-a non American intrepreation of European literature, history and politics
-European institutions still open to relationship with Google, but many with reservations regarding dynamics of relationship.
Wikipedia:Data Compression
-Involves encoding information using fewer bits than the digital representation would use
-advantage:helps reduce consumption of hard disk space or bandwidth
-negative:must be decompressed to be used that requires extra processing time and may effect running of some software
-loss less compression of algorithms to represent data consistently without error
-Lossy data compression involves perceptual coding
-with existing compression algorithms could currently store 4.5 X more information on existing systems

Introduction
Hello, Patty here. I am a fast-track student from Chicago. I am taking 2600 and 2324 this term.
I have three wonderful children, a great husband, two naughty dogs and an older sister living with me right now. I work full time at a public high school. After I am done posting this assignment I plan on watching the second half of the Chicago Bulls game while drinking a beer with my husband.
