<META>
Tags
<META>
tags enhance a search engine's ability to index HTML documents by placing
descriptive information into specific tags in the document's <HEAD>
division. Most search engines return this descriptive information, thereby
allowing searchers to make decisions about the usefulness of the match.
CERES has adopted the Dublin
Core metadata standard. This is a 15-element
metadata set intended to catalog electronic resources. CERES recommends
the use of the following Dublin Core <META> tags, where
applicable:
- <META name="DC.Title"
content="Title">
This tag contains the name
given to the resource, usually by the Creator or Publisher.
- <META name="DC.Creator"
content="Author or Creator">
This tag contains the
person or organization primarily responsible for creating the
intellectual content of the resource. For example, authors in the case
of written documents, artists, photographers, or illustrators in the
case of visual resources.
- <META name="DC.Subject"
content="Subject and Keywords">
This tag contains the
topic of the resource. Typically, subject will be expressed as
keywords or phrases that describe the subject or content of the
resource. The use of controlled vocabularies and formal
classification schemes is encouraged. For use in the CERES web,
please use vocabulary from the CERES
thesaurus.
- <META name="DC.Description"
content="Description">
This tag contains a
textual description of the content of the resource, including
abstracts in the case of document-like objects or content
descriptions in the case of visual resources.
- <META name="DC.Publisher"
content="Publisher">
This tag contains the
entity responsible for making the resource available in its
present form. Entries here should be things such as a publishing
house, university department, or corporate entity.
- <META name="DC.Contributor"
content="Other Contributor">
This tag contains a
person or organization not specified in the Creator element
who has made signifigant intellectual contributions to the
resource but whose contribution is secondary to any person or
organization specified in the Creator element (ie. editor,
transcriber, and illustrator).
- <META name="DC.Date"
content="Date">
This tag contains
a date associated with the creation or availability of the
resource. This date is to be of the form YYYY-MM-DD.
- <META name="DC.Type"
content="Resource Type">
This tag
contains the category of the resource, such as homepage,
novel, poem, working paper, essay, dictionary, and
technical paper.
- <META name="DC.Format"
content="Format">
This tag
conatains the data format of the resource, used to
identify the software and possibly the hardware that may
be needed to display or operate the resource. For use in
the CERES web, please use a mime type to specify the
format.
- <META name="DC.Identifier"
content="Resource Identifier">
This tag
contains a string or number used to uniquely identify
the resource. An example for a networked resource is
an URL. Other globally-unique identifiers, such as
ISBN are also possible entries for this field.
- <META name="DC.Source"
content="Source">
This tag
contains information about a second resource from
which the present resource is derived.
- <META name="DC.Language"
content="Language">
This
tag contains the language of the intellectual
content of the resource. Where practical, the
content of the field should be chosen from iso639a.txt.
Some commonly used languages are: German (DE),
English(EN), Spanish (ES), and French (FR).
- <META
name="DC.Relation" content="Relation">
This
tag contains an identifier of a second resource
and its relationship to the present resource.
Examples include and edition of a work, a
translation of a work, or a chapter of a book.
- <META
name="DC.Coverage" content="Coverage">
The
spatial or temporal characteristics of the
intellecutal content of the resource. Spatial
coverage refers to the physical region (use
latitude and longitude, bioregion, county,
city, etc.).
- <META
name="DC.Rights" content="Rights
Management">
This
tag contains a rights management statement,
an identifier linking to a rights management
statement, or a link to a service providing
informataion about rights management for the
source.
The following
are not Dublin Core meta tags but may be
useful to you in describing your dataset.
- <META
name="distribution" content="global"
or content="local">
This
tag lets the indexer know whether the
other <META> tags should be
used for global or local indexing. Only
home and/or top level pages should be
assigned content="global" --
assigning this value to all the pages of a
web makes much more work for external
search engines and reduces the value of
the indexed information. Subsequent pages
should contain content="local"
and those <META> tags can
be used by local search indexers (Harvest).
- <META
name="resource-type" content="document">
This
tag makes indexers look at the rest of
the documents <META>
tags. It must be present or else
indexers will only list the content of
the <TITLE> tag.
- <META
name="Reply-to" content="e-mail
address">
This
tag returns an e-mail address in the
index/search result.
