  12. Metadata: What is it?
    Metadata is information about information: moreprecisely, it's structured information about resources. This canbe a single set of hierarchical subject labels, such as a Yahooor Open Directory Project category. Or…

    More often, the metadata has several facets: attributes invarious sets of categories. This is often stored in databaserecord fields and tables, especially for product catalogs.
  13. Metadata: What is it?

    Examples of faceted metadata include:
    Music store: songs have attributes such as artist, title, length,genre, date...

    Recipes: cuisine, main ingredients, cooking style, holiday...

    Travel site: articles have authors, dates, places, prices...

    Regulatory documents: product and part codes, machinetypes, expiration dates...

    Image collection: artist, date, style, type of image, theme...
  14. Meta Information
    • <head>
    • <title>Meta Tags For Search Engines</title>
    • <meta name="description" content=“This where theorganization description will go.">
    • <meta name="keywords" content=" This where keywords related to the organization will go">
    • <meta name="rating" content="general">
    • <meta name="copyright" content="2003, BCIT">
    • <meta name="revisit-after" content="31 Days">
    • <meta name="expires" content="never">
    • <meta name="distribution" content="global">
    • <meta name="robots" content="index">
    • </head>
  15. Metadata: Faceted Metadata Search Solution
    A good solution to these problems involves exposing thefacets in dynamic taxonomies, so that the search user cansee exactly the options they have available at any time.

    They can switch easily between searching and browsing,using their own terminology for search while recognizingthe organization and vocabulary of the data.
  16. Metadata: Faceted Metadata Search Solution
    • Features for a good metadata search include:
    • Displaying aspects of the current results set in multiplecategorization schemes
    • Showing only populated categories, no dead-ends (linksleading to empty lists)

    Displaying a count of the contents of each category, warningthe user how many more choices they will see

    Generating groupings on the fly, such as size, price or date

    Drill down by facet, so a diamond buyer could choose price,clarity, size and setting.
  17. Metadata and Search: To sum up
    Be patient! The search engine spiders are extremely slowto index new information that they find when crawlingWeb sites. Don't be discouraged if it takes six months ormore to see the fruits of your labour.

    Individually submit your site to the more popular engines.

    Use a submission engine to target the rest.
