What does a good essay answer look like?

Sample question:

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.

Answer explained

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, schiller@vancouver.wsu.edu, 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.

  • 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?

Define Metadata

  • examples
  • uses
  • Why are they important?

  • Linnean taxonomy
  • Dewey Decimal Classification
  • database
  • web search engine
  • semantic data markup

Describe a relational database including
