This page lists extension values for the name="" attribute of the HTML <meta> element. You may add your own values to this list.
  
This page lists the allowed extension values for the name="" attribute of the <meta> element in HTML5. You may add your own values to this list, which makes them legal HTML5 metadata names. We ask that you try to avoid redundancy; if someone has already defined a name that does roughly what you want, please reuse it. Also, please be sure to include ''all'' the items [http://www.whatwg.org/specs/web-apps/current-work/multipage/semantics.html#other-metadata-names required by the spec] ''including a link to a specification'' that specifies the keyword ''as an HTML meta keyword''. Note that URL-valued properties must not be registered as meta names but should be registered as [http://microformats.org/wiki/existing-rel-values#HTML5_link_type_extensions rel keywords] instead. Also note that changes to this registry may not be reflected in validators in real time.

For assistance in preparing a specification, see the [[:Category:Specification editing|specification editing]] category and the [https://github.com/tabatkins/bikeshed/ Bikeshed] documentation.

| Searching for one content publisher's or page publisher's work requires a standard robot-parsable format for the information. This often differs from creator or author when the publisher is an institution. An institutional name, personal name, or other text entry is permissible.<br />One element represents only one publisher. Multiple publishers are to be represented with multiple tags, although multiple publishers are less common than multiple authors or creators; multiplicity is more likely for a legal name and a well-known name.<br />Search engines may index by any component of a name, so a publisher need only enter a name once in one order.

Defines the name of the machine that serves the web page. If you have two servers (Server1 and Server2), you would make two copies of the META tag and designate CONTENT=“Server1” for deployment to pages on the first server and CONTENT=“Server2” for deployment to the same pages on the second server.
 
For a server farm, you can extract the value of the built-in server name and dynamically assign it to the
 
META tag using server-side scripting.

Even though URLs are displayed in addition to page title, the entire URL cannot be depended upon to distinguish one page from another.

<META NAME="WT.ti" CONTENT="title">

| dcterms.subject
| To aid search engines in classifying and to aid directory compilers, an audience most appropriate for the page may be suggested. Subject matter may not be a good clue; for example, an analysis of children's literature may be directed to teachers.<br />A value is free-form case-insensitive text without a comma. Multiple values are to be comma-separated. Singular and plural forms have the same meaning.<br />Recognized values:<br />-- "all" and "everyone", which have the same meaning<br />-- "adult" and "mature" have the same meaning and are for content that only adults may access, but no one responsible for preventing a nonadult or the immature from accessing the page or its content should rely on either or both of these values to do so without other means (not the same as "grownup", which see)<br />-- "child" and "juvenile", which have the same meaning<br />-- "teen"<br />-- "grownup" is not identical to "adult" or "mature" in not implying a precise boundary but is approximately any person who may be able to understand and apply the content (e.g., car driving instruction that may be read by a minor not yet old enough to drive a car but who would likely benefit from somewhat early exposure to the instruction)<br />-- "parent" to include guardian and temporary caregiver<br />-- "teacher" to include professor and ad hoc instructor<br />-- "elementary school student" to include any student below high school<br />-- "high school student"<br />-- "elhi" to include any student in elementary school through high school<br />-- "college student" including graduate and professional school<br />-- "business" including management, finance, and prospective customers (this includes e-commerce and investor sites)<br />-- "health" including any health care provider including alternative and ad hoc<br />-- "patient" for any health care recipient<br />-- "lawyer" including judge, paralegal, and jailhouse lawyer<br />-- "law client" for any prospective recipient of a lawyer's service (not usually a social work client) with ''lawyer'' including paralegal and jailhouse lawyer but not necessarily judge<br />-- "craft" for any craftworker including laborer and artisan<br />-- "artist" including musician, actor, dancer, and sculptor and including creator and performer<br />-- "military" including paramilitary<br />-- "news" including any consumer of rapidly-developing news<br />-- "introductory" and "beginner", which have the same meaning<br />-- "intermediate" and "midlevel", which have the same meaning<br />-- "advanced" and "advance", which have the same meaning<br />-- "scholarly" and "scholar", which have the same meaning<br />-- "popular" generally referring to a writing style<br />-- "older" including retiree<br />-- "institution" including from corporation to conspiracy (such as for management advice)<br />-- "government" including agencies and prospective politicians<br />-- values using any integer or single-digit decimal in the form of "grade 8" or "grade 6.4" including to refer to a reading comprehension level (this generally will not exceed 12 and might be meaningless above 20 so higher values may be interpreted as the highest meaningful value)<br />-- "viewers" for when content (such as a movie) is intended almost entirely to be seen rather than read<br />-- "listeners" for when content (such as music) is intended almost entirely to be heard rather than read but not generally including text-to-speech support<br />-- "tts", "text-to-speech", or "text to speech", which three have the same meaning and which are for a page that has substantial support for TTS or that will be readily understood through TTS without need for such support (TTS is often aided by, e.g., pre-resolving pronunciation ambiguities in page coding)<br />-- values using any numbers in the form of "3-6 years old", whether a range or a single-number value<br />-- values using any decade in the form of "born in 1970s"<br />Unrecognized values such as "botanists", "Texans", and "writers who use red ink" may be used but at a risk that a search engine or directory editor will either fail to recognize it or will interpret it in unpredictable ways, or will in the future.<br />Spellings that are erroneous or slightly different from a recognized value may be interpreted by a search engine or directory editor as representing a recognized value.<br />The absence of the keyword defaults to a value of "all" but without overriding another indication arrived at by other means.

Search engines should respond to this meta tag in a reasonable way, i.e. by removing the page from their main search results after the expiration date (possibly still returning the result in a special search for expired pages as long as the page exists and is not explicitly excluded via <code>robots.txt</code> or <code>meta name='robots'</code> etc.) or simply by indicating to the user that this result is out-of-date.

The content attribute should define the expiration date in accordance with http://www.w3.org/TR/NOTE-datetime . The meta tag should not be used for pages without expiration date.

Label sizes should be proposed here for labels that are not on backing sheets that fit one of the recognized values, e.g., labels on narrow rolls. Blueprint paper sizes should be proposed here.

| The author may be the best expert on the geographic relevance of the content. Leaving that to search engine analysis may be too chancy without search engine optimization, which analysis is difficult to apply by algorithm to, e.g., historical papers and epidemiological studies which may mention locales only once.<br />Absence of the keyword defaults to a value of world (not universe), unless the search engine chooses to interpret the page or larger unit for some other value, probably based on other than just contact information given in the website.<br />The value for this keyword is a semicolon-separated list of one or more place-values, the order of which do not matter. One place-value will use commas to separate, in order, an optional standard natural language symbol applicable to the place-value (when omitted the language applicable to the page will control), a place-class, one or more place-subclasses if any, and one or more place name parts (where, e.g., in "Cape Town, South Africa", "Cape Town" is a place name part but "Town" is not). Spaces after semicolons and commas are optional; spaces within place-values are present when required for each place-value (e.g., "Quezon City", not an invented "QuezonCity").<br />To distinguish names that might otherwise be too similar, place-classes, all lower-case and hyphenatably spaceless, include ''outer-space'', ''region'' (on Earth and crossing or larger than a nation, e.g., southern hemisphere, polar region, temperate zone, or Asia), ''intntl-water'' (an 'international water body'), ''intntl-agcy'' ('international agency' or 'international collection', e.g., all U.N. member nations), ''nation'', ''within-nation'' (limited to only one political level down from nation, e.g., state, province, territory, possession, city not included within other political units of a nation, or any comparable unit), ''city'' (including town, village, hamlet, and any comparable political unit below the level of ''within-nation''), ''addr'' (including address, full-length street, building, institution, and neighborhood without political boundaries), ''pol-unit'' (''pol'' abbreviating 'political') (e.g., a place of disputed nationhood), ''hist-pol-unit'' (''hist'' abbreviating 'historical') (e.g., the Roman Empire), ''feature'' (e.g., river), ''num'' (e.g., latitude and longitude or outer-space equivalent in numbers), and ''ethereal'' (including thealogical/theological, fictional including from modern popular entertainment, and ancient secular mythical, but not including that which is asserted to be a state of mind or existence but not a place, such as nirvana). (Example for one hypothetical page: name="geographic-coverage" content="region, sub-Saharan Africa; nation, Panama; city, Panama, Panama; within-nation, Sao Paulo, Brazil; city, Sao Paulo, Sao Paulo, Brazil; within-nation, Mississippi, United States of America; region, Middle East; region, Midwest, United States of America; hist-pol-unit, Northwest Territory, United States of America; feature, river, Indus; outer-space, Indus; ethereal, ultima Thule; ethereal, Heaven; ethereal, Flatland; ethereal, Valhalla; en-US, addr, Hotel Valhalla, Fredrikstad, Norway; es, nation, Espana" (Indus is both a river and a constellation, illustrating the need for place-classes)).<br />Ambiguity of place-values should be avoided despite convenience in coding because search engines may each interpret them as they see fit, e.g., it would be hard for an engine to distinguish New York from New York.<br />For consistency of spelling, several authority lists should be settled upon, with legal, well-known, and disputed names and common abbreviations all being acceptable; but I'm not proposing one here now (relying on IANA's ccTLD list might be too complex to implement and still assure coding consistency, e.g., occasionally ccTLDs can be phased out and off of IANA's list) (a standard vocabulary possibly usable here is the [http://www.getty.edu/research/conducting_research/vocabularies/tgn/index.html Getty Thesaurus of Geographic Names Online], subject to licensing and charset choice); and promulgating authority lists may best be done publicly by search engine managements, who may disagree with each other.<br />Allowing Unicode for non-Roman alphabet-using locales is desirable, but at present that may raise technical problems, including computer security issues, that are not yet readily soluble.

| Pages may be revised several times daily. While date-time given to a granularity of a fraction of a second would often suffice, when a page has to be approved more than once before posting, any or no such time may be correct (without this keyword, a comment could be necessary but probably not parsable by an engine). In addition, versions regardless of date may show consecutiveness and can replace a date that must be vague. In that case, a version number may be more useful for searches and so a robot-parsable format is needed.<br />The keyword's value is stated in ASCII digits, is any nonnegative base-10 rational number expressed as an integer or a decimal, with any number of decimal places allowed, and may be padded with any number of leading zeros to support extraction for ASCII sorting.<br />Should this keyword appear more than once, only the first one so appearing is determinative.<br />The versions 0 and 0.''n'', with ''n'' being to any number of places, signify beta versions, i.e., drafts, in the tradition of beta software, while versions 1 and higher ordinarily signify final-release versions. After a final-release version is released, a draft of a later version is not given a version number of 0 or 0.''n'', but is numbered higher than the last final-release version. It is suggested to page authors that draft status, if applicable, be shown in the visibly displayed text of the page, rather than that this meta tag be relied upon as the sole notice of draft status, as it may be inadequate notice if alone.<br />To assign a low page-version such as 0.''n'' or 1, the page's URL, if static, may be used as the relevant premise. Thus, if a page is copied or moved to a new URL, the author may choose to restart page-version numbering from 0.''n'' or 1. If a page's URL is dynamic, e.g., if created on the fly from a script, the page author may prefer to use as the relevant premise for assigning a low page-version such as 0.''n'' or 1 the URL of the script or other technology that generates the dynamic-URL page, placing this meta element containing this attribute within the script or other technology, not within the generating page's head element (the generating page's head element may have its own meta element with this attribute describing the generating page). If one page containing the script or other technology that generates another page has more than one means for generating dynamic-URL pages, each means should contain its own meta element with this attribute. Page-version is thus largely independent of the page's date, although both would likely advance roughly in parallel.

| rights
+
| globrix.priceproximity
| As a page effectively appears in at least two forms, usually one as interpreted and displayed on a device and the other as source code, arguably intellectual property rights that must be asserted must be asserted in ways understandable in both contexts. For example, &amp;copy; is a raw representation that may legally fail as part of copyright notice to someone seeing source code and not the display, important when someone wants to copy source code for use elsewhere and may rely on a defense of innocent infringement (at least in U.S.). While such assertions can be made in a comment element, it may be helpful to have a tag that search engines can parse and index verbatim.<br />The value may include standard and nonstandard notices, invocations of licenses such as GFDL and ASCAP, and any other information. Content is defined as free-form, leaving the page author discretion for the entry.<br />Statements in one tag may discuss several portions of the page differently, e.g., with different licenses.<br />More than one license may be offered, along with the page's relationship to all.<br />Not all statements need be license grants. A statement may state whom to ask for reprint permission or may reserve all rights, for example.<br />Only one meta tag with this keyword may be present. Page authors must not use more than one. A UA finding multiple such tags on one page must ignore all of them.<br />The copyright symbol that would be generated by its character entity is not recommended for legal notice in source code when the word 'Copyright' may be used instead, because the entity may be read in raw form, but use is up to the page author. The same concept applies to any intellectual property rights symbol for which a suitable alternative is available, such as for trademark or service mark.<br />ASCII text would not suffice when a name or notice legally may have to be in a non-Roman alphabet, but no alternative may yet exist in HTML5.<br />Search engine storage may impose a length limit, but, because of legal consequences, if the value's length exceeds a given limit the search index should retain or interpret none of it but only refer to it.<br />The content string may only be copied verbatim in its full length, referred to, or ignored. It may not be, for example, paraphrased, truncated, interpreted, or classified except in addition to being copied verbatim in its full length.<br />Ignoring shall not void, nullify, or alter any rights stated in such tag.<br />For the synonymy, ''IP'', ''IP-rights'', and ''IP-right'' are not reserved; while the abbreviation ''IP'' 'intellectual property' is common among attorneys in the U.S., page authors will more likely be computerate, and the abbreviation may be wanted for 'Internet Protocol'.

| subj-. . .
+
| globrix.tenure
| To classify by subject a page's content, a standard subject taxonomy that will be recognized by a search engine or directory will help. Because many such high-quality taxonomies exist, only a prefix is proposed. Over time, particular taxonomies, in print or online, may be recognized here and keywords assigned for each.<br />The keyword will be constructed case-insensitively with subkeywords in the form subj-[nationAbbrev]-[taxonomy]-[edition][-optionalSubedition], e.g., subj-US-MeSH-2009online (perhaps). After "subj-", the second subkeyword will identify the nation where the taxonomy is published or offered as an aid in identifying the taxonomy and does not limit the subject coverage; e.g., a taxonomy published in Japan may be ideal for classifying Canadian botany or Peruvian economy.<br />As subject values may vary between editions of one taxonomy, an edition and optionally a subedition is to be identified in the third and optionally the fourth subkeywords. The subedition, if any, is any update or revision occurring between editions, such that a value drawn from that edition and subedition is stable. The means of identifying edition and subedition should be included in the registration of a keyword.<br />Examples of taxonomies from the U.S. include MeSH (medical) and the Library of Congress Subject Headings.<br />The value identifying a subject for a Web page will be drawn from the cited taxonomy's edition and subedition.<br />If the value should have a style to prevent ambiguity in interpretation, that style is to be registered here for that keyword. Multiple values are expressed with multiple meta elements, one value for each, since comma-separation is probably not compatible with all taxonomies.<br />If a value requires case-sensitivity to prevent confusion, the entry here registering the keyword must accommodate that need with the needs of HTML 5 with an appropriate rule. To that end, a proposal to allow case-sensitivity in meta tags under some circumstances has been offered in the W3C bug reporting system.

Example:
 +
<meta name="RATING" content="RTA-5042-1996-1400-1577-RTA" />

 +
 
 +
include the necessary code to generate a hit to the DCS. The maximum length for each name is 64 bytes.

If your site is hosted on multiple servers, a server cluster, or a server farm, and you want to evaluate the performance of your load balancer, Webtrends can track page views for each server. To do so, populate the following META tag on all pages on each server:
 +
Example:
 +
<meta name="WT.sv" content="My Server">
 +
Defines the name of the machine that serves the web page. If you have two servers (Server1 and Server2), you would make two copies of the META tag and designate CONTENT=“Server1” for deployment to pages on the first server and CONTENT=“Server2” for deployment to the same pages on the second server.
 +
For a server farm, you can extract the value of the built-in server name and dynamically assign it to the
 +
META tag using server-side scripting.
 +
Example:
 +
<meta name="WT.sv" content="Server1">
 +
<meta name="WT.sv" content="Server2">

| '''Tracking Page Titles'''
 +
You may want to modify a page title before sending it to Webtrends in the following cases:
 +
* You are dealing with dynamic content pages identified by URL parameters, and the page title represents the title of the base URL page rather than the dynamic content page.
 +
Unless you modify the page titles, all pages have the same title in the reports.
 +
* All pages have been assigned the same title, for reasons of style or company policy.
 +
Even though URLs are displayed in addition to page title, the entire URL cannot be depended upon to distinguish one page from another.
 +
Use server-side scripts to change the title to something that reflects the content of the pages so that you can identify them in reports. Next, pass the customized page titles to Webtrends, using the following META tag:
 +
<META NAME="WT.ti" CONTENT="title">
 +
Defines the name of the title for this page.

| expires
 +
| <code>meta name='expires'</code> defines the expiration date of the page. This can be used for web pages in preparation for an upcoming event, e.g. a registration form for an exposition or competition, or other cases with a pre-set date when the document will no longer be valid, e.g. a product offer in a special sale or a support page for a product known not to be supported anymore from a given time onward.
 +
 
 +
Search engines should respond to this meta tag in a reasonable way, i.e. by removing the page from their main search results after the expiration date (possibly still returning the result in a special search for expired pages as long as the page exists and is not explicitly excluded via <code>robots.txt</code> or <code>meta name='robots'</code> etc.) or simply by indicating to the user that this result is out-of-date.
 +
 
 +
The content attribute should define the expiration date in accordance with http://www.w3.org/TR/NOTE-datetime . The meta tag should not be used for pages without expiration date. However, for historical reasons, search engines should also interpret other date formats where possible and should be prepared to find values such as "", "0", "no" and "never". Such non-date values are to be interpreted as no expiration date.
 +
 
 +
Correctly formatted example:
 +
<code><pre><meta name='expires' content='2012-12-31T23:59Z'></pre></code>
 +
 
 +
This tag is not to be confused with and has a different meaning than <code>meta http-equiv='expires'.</code>

| og:description
| Microsoft introduced into Internet Explorer 6 Beta a feature that some website designers wished to preclude from applying in order to prevent public misunderstanding of their websites. The feature allowed a browser to add information but at a risk that users wouldn't know that it wasn't supplied by the website. This keyword was provided by Microsoft for those of us who wanted it.<br />Its value was "TRUE". Microsoft spelled the keyword with some capitals and the value in all capitals but whether capitalization was required for either is unknown; some opinions vary. Since it need be understood by only one browser, and that one a beta version, full standards compliance should not be assumed, and original case may be required. (This tag is used by Google: "<meta content='true' name='MSSmartTagsPreventParsing'/>" appeared (with internal quote marks as singles) in the source code for <http://googleblog.blogspot.com/2009/04/listening-to-google-health-users.html>, as accessed 4-27-09.)<br />Microsoft has apparently removed this instruction from its website on the ground that the beta version is no longer available and is not supported, but that doesn't assure that some users aren't still using the beta browser, perhaps inadvertently. Therefore, designers may wish to continue using the keyword and value and they are preserved here.

| resolutions
 +
| Authoring web sites to use resolution independent images that display beautifully on high-resolution displays should be made as easy as possible for developers and should not require JavaScript to accomplish.
 +
 
 +
To accomplish this, I propose a new HTML Meta Tag, <code>resolutions</code>, that can be used to specify that high-resolution versions of images linked to from the page are available and that the browser should use them in place of the lower-resolution default images if it detects that a user is using a high-resolution screen. The resolutions meta tag lists the device-pixel ratios supported by images in the page.
 +
 
 +
So, for example…
 +
 
 +
<code><pre><meta name="resolutions" content="2x"></pre></code>
 +
 
 +
… means that the developer is telling the browser that she has created 2x resolution images for the images linked to from the current page and named them with a @2x suffix.  
 +
 
 +
To illustrate, if her image tag is as follows…
 +
 
 +
<code><pre><img src="/images/flower.jpg" alt="A flower"></pre></code>
 +
 
 +
… then she has two image files under /images: the low-resolution default (flower.jpg), and a higher-resolution (200%) version named flower@2x.jpg.

(This is the same naming convention already used by Apple in its Cocoa Touch framework for automatically loading in higher-resolution versions of images.)
 +
 
 +
Based on the meta tag, if the browser detects that the user is running at a <code>min-device-pixel-ratio</code> of 2.0, it will automatically ask for the 2x version of the image (flower@2x.jpg) instead of the default image as specified in the image tag.  
 +
 
 +
Finally, so as not to flood external sites with high-resolution image requests, this functionality would only work for local images specified via relative links.
 +
 
 +
<b>Multiple resolutions</b>
 +
 
 +
The resolutions tag can also contain a list of supported device-pixel ratios so as to support even higher-resolution displays when and if they become available in the future.
 +
 
 +
For example:
 +
 
 +
<code><pre><meta name="resolutions" content="2x, 4x, 8x"></pre></code>
 +
 
 +
In this case, the developer would provide 2x, 4x, and 8x versions of all images. So, in the running example, she would make flower.jpg, flower@2x.jpg, flower@4x.jpg, and flower@8x.jpg.
 +
 
 +
<b>Advantages</b>
 +
 
 +
The advantages of this approach are several:
 +
 
 +
<ol>
 +
    <li>Makes it very simple for developers to support high-resolution displays like the iPhone 4's Retina screen</li>
 +
    <li>Does not require JavaScript</li>
 +
    <li>Does not change the default way that things work (if the meta tag is not specified, the browser simply behaves as it always has).</li>
 +
</ol>

This page lists extension values for the name="" attribute of the HTML <meta> element. You may add your own values to this list.

For assistance in preparing a specification, see the specification editing category and the Bikeshed documentation.

If the specification is ready, we ask that you:

  • Avoid redundancy. If someone has already defined a name that does roughly what you want, please reuse it.
  • Be sure to include all the items outlined in the spec including a link to a specification that specifies the keyword as an HTML meta keyword. If a proposal lacks a specification and a version in a complete specification exists, the latter is to be preferred.
  • Alphabetize by keyword, without regard for case, in any table. Sort nonalphanumerics by ASCII value.
  • Not reserve namespaces. Instead, register individual names (known as enumerated values although you don't have to number them).

URL-valued attributes must not be added to this page as meta names but should be registered as rel keywords instead.
