Week 9 Notes

1) Martin Bryan. Introducing the Extensible Markup Language (XML)http://burks.bton.ac.uk/burks/internet/web/xmlintro.htm

This article was insightful in that it presented XML as a very accessible tool. I found its distinction of the three mark up types, XML processing instruction, document type declaration, and root elements, clear and focused.

I also enjoyed the discussion of the processes the XML allows: the bridging of multiple files, the ability to identify where images are to be incorporated, the processing control, and the addition of editorial comments. Also insightful was the inclusion of what XML is not: a predefined tag, or a standard template for the creation of documents.

2) Uche Ogbuji. A survey of XML standards: Part 1. January 2004.http://www.ibm.com/developerworks/xml/library/x-stand1.html

I liked how this survey was broken down. I found it both readable and comprehensive. The rest of this section will be notes.

- XML: depends on unicode to define strict rules for text formatting
- Catalogs: define a format for instructions on how an xml processor resolves xml entity identifiers into actual documents.
- XML namespace: provides a mechanism for universal naming of elements and attributes in xml documents.
- XML Base: provides meaning of associating xml elements with URL's in order to be most specific on how relative URL's are resolved in xml processing actions.

3) Extending your Markup: a XML tutorial by Andre Bergholz PDF

This tutorial allowed me to gain a much better sense of the impact of a more meaningful mark up. The article included: XML namespace, stylesheets, and schema. Schema included: doc defintion mark up language, doc content description, schema for object orientation, and xml data.


I was really able to focus on the meaning of XML schema here.

Schema is: an element that can, appear in a doc, provide attributes to that document, define wat elements are child elements (including the number the doc contains).

The tutorial also aided in my understanding of why someone would use XML:

XML is (shortly): easier to describe, it validates correct data, it also defines data, facets and patterns, and it provides the user with no need to learn additional languages- thus allowing for the use of old schemas.

Week 8 Readings

Sorry about this post, it is rather dry.

1) W3schools HTML Tutorial: http://www.w3schools.com/HTML/

I've accessed this website before for a computer science class I took as an undergrad. It is really helpful as it breaks each tag down and gives great examples. I also really appreciate the ability to "try it out." This is a very helpful tool for new HTML users. Below I have included some of the tags I would like to keep reference of. In my use of HTML I have found this pages reference to table tags most helpful.

2) HTML Cheatsheet http://www.webmonkey.com/reference/HTML_Cheatsheet/

This cheatsheet form webmonkey, "the web developer's resource" is very useful. I love that the cheatsheet is a list. It is helpful, easily accessible, and and highly informative. Its selection of frame tags are very helpful as their are greatly detailed, covering a vast array of scenarios. Again, I have added some references I would like to reference.

3) W3 School Cascading Style Sheet Tutorial: http://www.w3schools.com/css/

Aside from the helpful content, particularly the color sheets, the tutorial is interesting in its assertion that HTML was never intended to house style sheets:

HTML was intended to define the content of a document, like:

When tags like , and color attributes were added to the HTML 3.2 specification, it started a nightmare for web developers. Development of large web sites, where fonts and color information were added to every single page, became a long and expensive process.

To solve this problem, the World Wide Web Consortium (W3C) created CSS.

In HTML 4.0, all formatting could be removed from the HTML document, and stored in a separate CSS file. All browsers support CSS today.

4) Goans, D., Leach, G., & Vogel, T. M. (2006). Beyond HTML: Developing and re-imagining

library web guides in a content management system. Library Hi Tech, 24(1), 29-53.

Dev system using MySQL and ASP

New system exceeded their expectations, providing, “greater control over appearance and navigation while still offering customization features for liaisons. When integrating a CMS attention must be given to user issues and technical issues Initial lack of control over content, architecture and organization led to inconsistency. – too diverse, lack of training was at time apparent- doesn’t seem like a good expenditure of time, or money for that matter. Minimal security, not robust-

First web dec librarian hired in 2000- implement web security for Frontpage, also built MySQL applications to manage databases and e journals as well as photographic collections. – however, unregulated creation of guides still continued.

2003- site standards identified four common elements, database technology could now be applied to GSU guides. Away from static HTML into more dynamic and automated system.

CMS defined: Collecting, managing and publishing content. A database or repository is oversimplifying it.

The content is disconnected from the layout and design elements of the page guides are created in form based environment- helps with inability or lack of experience in HTML. Lib can focus on content rather than presentation. Content definition depends on institution. Reusability is also a key element, material can be reused and added to without disruption. Object-oriented site development.

Allows for enhanced editorial access while still functioning as a limited gatekeeper to provide cohesive visual and navigational standards.

By limiting content style editing, users know what to expect in each guide, ease of use and access is increased.

Tagging allows for lib to create cross referenced user guides. – enhanced the reuse of content. Opportunity to create unique descriptions. Metadata customization gives meaning and additional context.

There are commercial options, open sources options and In-House options.

GSU CMS technology is made up of resource tables, metadata, and personnel metadata tables. Edits are done through administrative forms.

Great examples of directories. Interesting representation of HTML. Librarians can edit resources and web pages while site admins have online forms to edit or add website sections and also assign people and authorship rights. – manages presentational control. This structure has helped to reduce redundancy, lack of cohesion, and has increased user ability of the guides.

The decision to build the database around existing categories was due to cost, staff, and the desire to limit the reworking of the guides. – varying degree of HTML/CSS experience. – reason for migrating was clearly communication. One of the ultimate goals was to build a system that could ultimately be expanded to other departments.

How might we learn from this experience? I would imagine that the very opportunity to include reference guides is out of reach for some less funded libraries. Perhaps the GSU experience can save future libraries the time and funding of reformatting and training.

Week 7 Muddiest Point

I have no muddiest point for this week.

Week 7 Readings

1.Tyson, Jeff. http://computer.howstuffworks.com/internet-infrastructure.htm/printable

This article was really helpful as we have already discussed many of these points in class on Tuesday. Generally, we have not touched on issues presented in the readings and thus, their content is less comprehendible- for me, anyways.
The article aided my understanding in the hierarchy of computer networks. All computers (connected to the web) are part of a network, LAN, WAN. In connecting to the network, each computer receives an IP (protocal) address that allows it to connect to larger preexisting networks. Each region has a POP (point of presence), or place where local users are able to access the network.

I also found the internet backbone section interesting. I was unaware that NSF had created the first network backbone. Additionally, I was surprised to discover that they continued to invest in backbone creation with IBM and MIT; this collaboration resulted in the creation of the T3 Network (1988).

2.Andrew K. Pace (2004). Dismantling Integrated Library Systems. Library Journal, 129(2), p.34-36. Full Text

This article is distinct in its practical, yet frank, tone. I find Pace's evaluation of ILS (integrated library systems) to be genuinely rooted in practical field concerns. His evaluation aids the reader in considering the multifaceted options, downfalls, and opportunities facing libraries due to the advent of increased formats and user requests. His evaluation that, "The vendor should not limit what customers can do with new products based on technical constraints of the standard ILS" is to be highly considered when transitioning into a new ILS platform (or in the act of overlaying a new platform over top the already existing. He leaves libraries with two choices;

"[libraries] can continue to maintain large systems that use proprietary methods of interoperability and promise tight integration of services for their customers. Or, they can choose to dismantle their modules in such a way that librarians can reintegrate their systems through web services and standards, combining new with the old modules as well as the new with each other."

These are vital options to consider, and should include an evaluation of each institutions budgetary constrains, institutional goals, and patron base.

3. Sergey Brin and Larry Page: Inside the Google machine.
http://www.ted.com/index.php/talks/sergey_brin_and_larry_page_on_google.html

I really enjoyed this video. Initially, it was as if I was watching a science fair video- strange, unsettling, and incredibly awkward. However, Brin and Page eventually, and successfully, transitioned from awkwardly placed jokes and broad sweeping global network discussions to the more professionally based examination of their organization. I must say though, the world network program was pretty sweet (and disturbing) to watch. While the video did focus a considerable amount of time discussing Google's philanthropic efforts, they also discussed their business practices geared at embracing employees ideas and strengths as assets.

This is actually a great tool. I really think it could aid in the instruction of library service..esp those of online database searching.
