You can also use the META generator at SafeSurf to generate a PICS header - a multi-valued, multidimensional ratings scheme for classifying Web pages for use with kid's Web software or PICS-compliant browsers such as MSIE.
Title (Strongly Recommended)
Your documents title will appear in user's hotlists, the banner of most
browsers, and robot-generated lists. It should be a concise, one-line
summary of what the page is about.
Bear in mind that users may not reach your document through your homepage,
but directly using a search engine or link at another site, so the title
should ideally be self-sufficient.
Space-separated list of key words for indexing your document.
Some robots look at keywords in context, so it is best to preserve word order and case, e.g. pizza, Vancouver, British Columbia rather than british vancouver columbia pizza
The description is presented to the user along with
the document's title as the result of a search.
Many robots use the first few lines of text as a description if the Description tag is not present. For documents using frames, it is possible that there is no such text present. For an academic text, this should probably be the abstract.
Legacy value. Some browsers (e.g. Lynx) use this to mail
the document author; e.g. "Joe@blow.org".
The name of the creator of the resource (author,
graphic artist, photographer etc.), e.g.
"Vincent Van Gogh"..
The topic of the resource, or keywords or phrases that describe
the subject or content of the
The entity responsible for making the resource available in its present form.
The organisation hosting the Web page, perhaps.
Persons or organisations other than the Creator who made
a secondary contribution to the work.
The geographic coverage of the resource. For each
distinct area covered, use a separate element.
Placenames from a reference such as the Getty Thesaurus are recommended.
You may use comma-separated names, ( * Syntax in negotiation ) e.g. "Canada, Quebec, Hull", to define a region more exactly, if ambiguity exists (e.g. London, Birmingham, Vancouver, etc.).
It is intended that searchBC be enhanced to
traverse pages with British Columbia in this element.
The geographic location of the resource, if meaningful. x is Longitude,
y is Latitude, in decimal degrees, East positive, North positive.
z is elevation in metres. The WGS84 geodetic scheme (as used in GPS
receivers) should be used, unless an accuracy of less than 200 metres is sufficient.
The form will perform some conversions. Any field may be filled in with a decimal number, so the following are all valid as Latitude:
For a demonstration of language negotiation and charsets, see the Multilingual page.
You may use the browser test script to
discover if your browser is sending an HTTP_ACCEPT_LANGUAGE header.
Charsets may be specified by the server; for instance:
Content-type: text/html; charset=iso-8859-5
Netscape 2.0 works properly with this method; unfortunately, most other browsers break. Netscape 3 will use a META tag to automatically switch fonts (X11 Netscape, at least), and provided the server does not parse HTTP-EQUIV META tags into real HTTP headers, other browsers will ignore it. Thus this method becomes recommended for non-ISO-8859-1 (Western European) character sets, as it will cause Netscape to select the correct font for each page.
SearchBC will index this META tag. The default HTML charset is ISO-8859-1 (Western European 8-bit).
See How to make a Multilingual Webserver for more information about using Charset and Language tags.
The Dublin Core element DC.language uses a 3-character string from
The Other input box in the form accepts a language from this list, e.g. Basque, and looks up the 2 and 3-letter codes in a table.

<META NAME="ROBOTS" CONTENT="ALL | NONE | NOINDEX | NOFOLLOW"> default = empty = "ALL" "NONE" = "NOINDEX, NOFOLLOW"The filler is a comma separated list of terms:
Discussion: This tag is meant to provide users who cannot control the robots.txt file at their sites. It provides a last chance to keep their content out of search services. It was decided not to add syntax to allow robot specific permissions within the meta-tag.
INDEX means that robots are welcome to include this page in search services.
FOLLOW means that robots are welcome to follow links from this page to find other pages.
So a value of "NOINDEX" allows the subsidiary links to be explored, even though the page is not indexed. A value of "NOFOLLOW" allows the page to be indexed, but no links from the page are explored (this may be useful if the page is a free entry point into pay-per-view content, for example. A value of "NONE" tells the robot to ignore the page.

Data entered in the MetaGenerator form is not released to any other
organisation. Currently, it is not saved and is used only for generating
the results page. However, this is not a secure server and data could
conceivably be monitored, the most likely places being on an Ethernet segment
at your site or inside your computer by a trojan horse program.
