The final will take place on Wednesday, May 2nd from 8am to 10am our accustomed classrooom, VMMC 111.
What does a good essay answer look like?
Metadata may be the single most important concept discussed in this course. Why all the fuss about metadata? Please write an essay describing what purposes metadata serve and how they are used to organize information and help searchers find what they are looking for. In your essay, please include a detailed definition of metadata and practical examples of how they are used to help people organize and find the information they are looking for.
Factually correct answer
Metadata are data about data.
Metadata are descriptive labels. They explain the context or significance of the data. A simple example of metadata are labels in an address book. When you have a blank entry in your phone's address book the blank lines are where the data will be entered. The descriptive labels are the metadata that tell you what data to enter on which lines.
Answer contextualized with examples
In a database, a common second-order tool, metadata take the form of fields, or the labels that describe the fields. In a standard table, the field labels would be the columns. In a web search engine, the metadata are less structured and more haphazard. Weinberger claimed that "metadata is what you know and data is what you don't know" since any word can be used to find connected words. In address book example used above, "Name" "email address" "phone number" "place of work" are all common metadata labels for an address book, they describe and give explicit context to the data (Nicholas Schiller, firstname.lastname@example.org, 360-546-9171, WSU Vancouver Library) that follows them.
Complete answer, check to make certain all aspects of the question/writing prompt have been answered.
Metadata are used to define fields and explicitly label information in organized systems. Metadata tell the searcher what will be found in a specific area. Without metadata we would just have a chaotic jumble of data without context. We would be forced to examine every individual item in a set in order to know what is in it. For example, without metadata or context the word blues could refer to a range of colors, a kind of jeans, a genre of music, or a melancholy mood. Metadata makes the context for a datum (an individual unit of data) explicit.
Things you will want to be able to write about for the final exam:

- What challenges are commonly faced?
Explain Weinberger’s three orders of order.
- Give an example of each.
- Explain what each is good for (list a situation where this would be the perfect solution to a problem)
- Explain the key characteristics of each (what makes it special)
Explain the process of classification, including:
- The role of authority
- Why do people classify?
- What is a taxonomy?
- Why are they important?
Be ready to explain certain key information organization systems. (order, uses, significance)
- Linnean taxonomy
- Dewey Decimal Classification
- web search engine
- semantic data markup
Describe a relational database including
- table, record, field
- what does this tool do well?
- What kind of problem is this tool unsuited to solve?
- How does one use this tool?
Explain how to effectively search a database of scholarly articles
Explain how semantic markup makes data on the web act like data in a database.
- structured data / metadata standards
- explicit metadata vs. implicit metadata
Describe a web search engine including:
- crawler, index, PageRank
- internal/external meta information
- anchor link text
- What is this tool good at that no other tools can match?
- What kind of problem is this tool unsuited to solve?
Describe a social taxonomy tool such as Delicious, Flickr, Pinterest, or Diigo

- Contrast with a database (also with search engines)
Explain the silverware drawer analogy
“Knowing what you are looking for is just as important as finding what you know you need.”
Bits versus Atoms
- Links vs. things
Tags and Categories
- Compare and contrast in terms of:
- Which order of order?
- bits vs. atoms
- freedom vs. control
“everything is miscellaneous”
- What does this claim mean?
- Evaluate this claim for its relative strengths and weaknesses
Known Item Searching and discovery
Compare and contrast implicit information versus explicit information
What are some advantages and disadvantages to using authority to organize information?
Open up a blog entry titled: Semantic Web Class Exercise.
Answer the following questions:
- What are some direct connections between the HTML 5 Microdata and Schema.org article and the Weinberger text? You are looking to identify three concepts from Weinberger that the article addresses. For each concept, please define or describe according to Weinberger and then describe in detail how the article addresses them. (A hint and an example: items in HTML5 microdata are what Weinberger calls smart leaves.)
The reading for Wednesday April 11 is HTML 5 Microdata and Schema.org.
WordPress Organization Project Instructions have been uploaded to the Instructions and Help Documents page.
Today we are going to experiment with WordPress and putting our post in some sort of order.
Your most basic choices are chronology, categories, and tags.
Chronology is the order of posts. By default they are in reverse-chronological order. This biases the most recent over the older. There is a plugin available that reverses this and allows you to choose a bias for older over newer.
Categories allow you to perform a 2nd order classification. You may diagram a taxonomy and choose categories to represent levels of your order. Categories are neat and orderly. WordPress allows you to place posts in more than one category, so you may also take advantage of the property of digital objects that allows them to be in more than one place at a time.
In today's class (March 28th 2012) we will be watching a talk given by Douglas Rushkoff at the Google campus. He describes his book Program or be Programmed: 10 Commandments for the Digital Age.
As you watch, please take notes in a blog entry and try to capture at least one ethical issue that information users face today. Try to identify something that has a range of possible responses and isn't just a simple binary good/evil distinction.
