CLF for the Internet - Navigation and Format
Standard 6.3All GoC Web sites must adopt the following five metatags as a metadata standard for description of Web resources: Title, Originator, Language of Resource, Date and Controlled Subject. Metatag Generator Common Look and Feel Metadata Standard Definitions and HTML Examples META Tag Generator is a tool which accepts user input and will generate HTML code according to the standard which can be pasted into an HTML page. These five metadata elements are part of the 15 element Dublin Core Metadata Element Set, the leading international metadata standard for on-line resource discovery. RationaleMetadata is a key tool in describing and managing information assets. It is particularly important to have an effective identification system for information assets since many are invisible, hidden in Web sites or databases, until a user initiates a search to find the assets relevant to a current need. Whether we in the public service or our clients in the Canadian public are the searchers, we need an effective way to use the labels on our information assets to find them when we need them. You can see that the chair you are sitting on is a chair without looking at the bar code label, but an electronic document is invisible until its label or its text is found by a search tool. The benefits of using a systematic way of assigning and structuring metadata include:
For more information see: Selecting and Implementing a Metadata Standard for the Government of Canada InterpretationEssentially information about information, metadata is made up of elements that define standard descriptions of information holdings. This CLF standard is based on Dublin Core and requires GoC institutions to describe Internet resources using five mandatory metatags in document headers: Title, Originator, Language of Resource, Date and Controlled Subject. Link: Common Look and Feel Metadata Standard Definitions and HTML Examples The Canada Site includes a Web crawler that indexes departmental sites to create a searchable central index. As departments create metatags to describe their information holdings, the Web crawler will incorporate these records in the central index. The Canada Site search index will be configured to recognize Dublin Core metatags and use them in ranking and displaying results. 6.3 Best PracticesTo complement the use of these mandatory GoC metatags, Web developers should also ensure that the HTML Title element and two HTML meta elements, Description and Keywords are specified. Authors should use the Title element to identify the contents of a document. Since users often consult documents out of context, authors should provide context-rich titles. The content of the HTML Title tag is displayed as the window header in a Web browser, in bookmarks and in search results. Common search engines may use the contents of the Keywords tag to improve the quality of search results. The contents of the Description tag may be displayed as a summary in search results. The display of these elements is limited in length by browsers and search engines. Departments or Web sites requiring additional metadata elements should use the additional Dublin Core elements as a starting point. In accordance with the Government of Canada Metadata Framework domain specific metadata element sets may be developed with the mandatory Common Look and Feel and additional Dublin Core metadata elements at their core. These guidelines were developed by members of the GOL Metadata working Group during the summer of 2002 and approved at the September 17, 2002 meeting. This document targets departments developing indexing policies for the population of the Common Look and Feel mandatory element <dc.subject>. Two user-friendly web-based guides are now available on the Council of Federal Libraries' site (September 2002) An Implementation Guide
for Metadata Developers offers practical assistance to those responsible for
creating metadata content for federal government Web pages in accordance with the
Common Look and Feel standard. It explains the tasks to be performed, demonstrates
how the required information should be created and directs readers to other
resources. It also provides instructions on how and where to insert the required
source codes into a Web document. How to register a controlled vocabulary or thesaurus for use in dc.subject on federal government Web sites: Registering a Standardized Vocabulary LinksSearch to select subject descriptors: Common Look and Feel Metadata Standard Definitions and HTML Examples |
