Week 5 Multimedia Representation and Storage
Data compression is an interesting and semi confusing topic, for me.
Compression: the process of encoding information using fewer bits than the encoding representation. Compression is used to optimize disk space.
In practice, lossless and lossy compression are easy enough to grasp.
Lossless- complete algorithem, through exploitation of statistical redundancy the data can be compressed and decompressed without change or error.
Lossy- data compression through perpetual coding. This form of compression is only acceptable when minimal data loss is acceptable.
The only past experience I have had with compression is the lossless compression of music files onto a cd. At the time, I must admit, I knew absolutly nothing considering the difference between lossless and lossy compression. I am sure that this lack of understanding resulted in some, if not all, of the aggrevation I felt while attempting to compress those music files. This may be in part due to my additional lack of understanding that for compression to be successful both the sender and reciever must both recognize the schemes being used.
2. Data compression basics (long documents, but covers all basics and beyond):

I found this article most interesting in its description of Run Length Encoding (RLE). Before reading this section, I do not believe I was able to grasp the steps of compressing data. Sensibly, Run Length encoding replaces the run (of the character) with a single digit followed by the length of the run.
3. Edward A. Galloway, “Imaging Pittsburgh: Creating a shared gateway to digital image collections of the Pittsburgh region” First Monday 9:5 2004 http://www.firstmonday.org/issues/issue9_5/galloway/index.html
This report offers an interesting glance into the process of working collaboratively on a digitization project. I found most interesting their examination of the challenges they faced in choosing a standard metadata format. I think there resolve to adopt 9 mappings in Dublin Core shows positive paths that can be taken in collaborative projects. Additionally, I like there decision to use the controlled vocabulary of LCSH. Finding common ground in a project with such a scope can be a real challenges, it sounds like they worked well to create a meaningful project.
4. Paula L. Webb, YouTube and libraries: It could be a beautiful relationship C&RL News, June 2007 Vol. 68, No. 6 0
This article discusses the ways libraries could, and have, used YouTube to spread information to their patrons, these include: instructional media, updated user information, and upcoming events.
This article raised a few questions for me, including:
1. Would individual institutions develop a formal guideline for the creation and format of their videos?
2. Who within the library would become responsible for monitoring these videos, let along producing, editing and uploading them.
I have used YouTube to share videos with my family and agree that it is a great venue for sharing. However, moving from video creation to posting does involve work..I wonder who's shoulders this would fall on.
3. Would funding for the work discussed above come out of libraries multimedia budgets, such as those for in house instructional media sessions?

Week 1 reading notes/musings
Readings:
1) OCLC report: Information Format Trends: Content, Not Containers (2004).http://www.oclc.org/reports/2004format.htm
2) Clifford Lynch, “Information Literacy and Information Technology Literacy: New Components in the Curriculum for a Digital Culture” http://www.cni.org/staff/cliffpubs/info_and_IT_literacy.pdf
3) Vaughan, J. (2005). Lied Library @ four years: technology never stands still. Library Hi Tech, 23(1), 34-49.
1)OCLC report: Information Format Trends: Content, Not Containers (2004).http://www.oclc.org/reports/2004format.htm
* Interesting concept of unbundling content
Short discussion on content trends
* Legitimacy of open-source publishing, collaborative entries, e published books, journals (blogs)
* Wordpress, Movable Type
* Expanding economics of micro content
* Old content repurposing
*Portable device multimedia
* Contextual searching
While the articles partial focus is on content legitimacy it lacks a mentioning of information security. This got me thinking about the effort required in sustaining an open source publishing tool. For the user/admin the container represents a value of time and effort. How able is the user/admin able to maintain the platform? To what cost to we sacrifice legitimacy for ease of use? Discussing content as opposed to container incites a need to explore deeper the platforms for open source publishing.
2) Clifford Lynch, “Information Literacy and Information Technology Literacy: New Components in the Curriculum for a Digital Culture” http://www.cni.org/staff/cliffpubs/info_and_IT_literacy.pdf
This opinion paper draws comparison between information literacy and information technology literacy. Drawing from his varied background, Clifford Lynch develops the following summaries of these two aspects of literacy:
Info Tech Lit: Understanding of technology infrastructure, tools that allow for interaction, and the legal and social policy shaping these.
* Lynch finds two perspectives on information technology lit- skills in use of literacy tools (word, etc) and proficiency in the infrastructure.
Info Lit: Content & communication, authoring, research and findings. Variety of content: text, video, etc. Variety of purpose: education, art, etc.
* Lynch comments on the need to develop for oneself an understanding of the policy that drives information in the digital age. This notion raises interesting thoughts on information literacy education, search proficiency, and the changing state of information practices.
3) Vaughan, J. (2005). Lied Library @ four years: technology never stands still. Library Hi Tech, 23(1), 34-49.http://www.emeraldinsight.com/Insight/ViewContentServlet;jsessionid=C5A0E976F56F442F9919082BF1F79360?Filename=Published/EmeraldFullTextArticle/Articles/2380230105.html
This case study by Jason Vaughn examines the progress, challenges, and future of the Lied Library at UNLV. His discussion of the evolution of the library's systems left me completely swimming in software! Sooo..
EzProxy: Remote access (OCLC), providing access to e-information, catalogs
http://www.oclc.org/ezproxy/
DiMeMa (Digital Media Management): Organization controlling CONTENTdm. CONTENTdm allows for the storage, management, and delivery of digital collection. (http://www.oclc.org/news/releases/200633.htm).
This article from OCLC's webpage denotes their acquisition of DiMeMa.
Serial Solutions: ProQuests E-resource access, assessment, and management service. (http://www.serialssolutions.com/).
SFX: Widely used link service providing content based links for "library-defined resources"- Ex Libris (http://www.exlibris.co.il/category/SFXOverview)
Docutek ERes: E-reserve system managed by SirsiDynix. (http://www.docutek.com/products/eres/index.html)
Uniprint: Virtual printing service allowing for remote printing, networked printing, and security. (http://www.uniprint.net/home.asp).
I find Vaughn's assessment of the Lied Library as a leader in practice, planning, and infrastructure too awarding, at times. I have no doubt in the institutions position as an exemplary model for management and planning. However, Vaughn's explanation of the library's funding projects leaves much to desire. Only in the conclusion does he expand on the necessity of collaborative funding as a vital component in the library's future longevity. This absent component leaves the reader wanting for explanation of their current funding endeavors.
