Specifications Not Developed
» Email someone you know about this page.
I wrote and posted some specifications that I don’t think need further development by me, although not necessarily because they are already optimal. Other parties may also have contributed to their content.
Current Status at MetaExtensions
The current status of any HTML meta element name attribute value at the official page of HTML meta element extensions, stated or implied on this page, may have changed without this page having been updated. While, hopefully, this page will be updated accordingly, that cannot be promised. Therefore, any question about the current status should be addressed by examining that official page and its viewable history of revisions (and page differences may be available).
Candidates For Abandonment
The following may each warrant abandonment or have been abandoned. All were for HTML meta elements with the following name attribute values, which are here listed in alphabetical order:
- — addmark — a version was, for approximately five months in and not since, at the official page of HTML meta element extensions; a discussion beginning before the name attribute value is at https://www.w3.org/Bugs/Public/show_bug.cgi?id=6774; the history of the name attribute value there begins at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3624 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3624&oldid=3540) and continues at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3625 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3625&oldid=3624), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3626 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3626&oldid=3625), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3695 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3695&oldid=3626), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3700 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3700&oldid=3695), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3727 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3727&oldid=3705), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3810 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3810&oldid=3732), and at

- — bot- — see list item on this page for “bot-. . .”

(namespace defined by the beginning being “DC.”) — a version is at the official page of HTML meta element extensions (scroll to or search for “DC.” in a Keyword column); the history of the name attribute value begins at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=4088 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=4088&oldid=3824) and continues at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=4758 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=4758&oldid=4526), whether revised or not (it probably was not) in the course of being moved on the WHATWG MetaExtensions wiki page then at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=5908 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=5908&oldid=5604), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=6432 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=6432&oldid=6431), and at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=6557 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=6557&oldid=6519); the reserving of namespaces in lieu of enumerating names is discouraged or forbidden and numerous name attribute values that begin with “dc.” with the prefix being equivalent despite case have been added to the official page of HTML meta element extensions
- — dir-content-pointer — a version is at the official page of HTML meta element extensions (scroll to or search for “dir-content-pointer” in a Keyword column); the history of the name attribute value begins at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3727 (with the differences page at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3727&oldid=3705) and continues at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3810 (with the differences page at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3810&oldid=3732), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=3811 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=3811&oldid=3810), whether revised or not (it probably was not) in the course of being moved on the WHATWG MetaExtensions wiki page then at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=5908 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=5908&oldid=5604), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=6432 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=6432&oldid=6431), and at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=6557 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=6557&oldid=6519); its function is, I think, adequately handled by other elements in HTML 5.1 that may not have been in a predecessor version of HTML when this name attribute value was proposed
Candidates For Lead on Maintenance by Other Parties
Some of the following substantially came from other sources and, for all of the following, other parties are better qualified to maintain them. They were for HTML meta elements with the following name attribute values, which are here listed in alphabetical order:
- — application-name — a version is at the official page of HTML meta element extensions (scroll to or search for “application-name” in a Keyword column); the history of the name attribute value at WHATWG begins at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=10013 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=10013&oldid=10012) and continues at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=10014 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=10014&oldid=10013); the name attribute value has a history in the HTML Living Standard, in HTML 5.1, and at Microsoft; and WHATWG (for the HTML Living Standard), W3C (for HTML 5.1), and Microsoft are better qualified than I am to maintain a specification for this name attribute value
- — Baiduspider (or baiduspider) — a version, referenced as a synonym of another name attribute value, is at the official page of HTML meta element extensions (caselessly scroll to or search for “Baiduspider” in a Keyword column); the history of the name attribute value at WHATWG begins at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=4088 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=4088&oldid=3824) (at this datetime the specifications for “googlebot”, “msnbot”, “slurp”, and “TEOMA” were combined into one and “Baiduspider”, “ia_archive”, and “twiceler” were newly added into the combined specification) and continues whether revised or not (it probably was not) in the course of being moved on the WHATWG MetaExtensions wiki page then at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=5908 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=5908&oldid=5604), whether revised or not (it probably was not) in the course of being moved on the WHATWG MetaExtensions wiki page then at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=6431 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=6431&oldid=6430), at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=6433 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=6433&oldid=6432) (including that at this datetime the name attribute value “baiduspider”, newly re-authored in all lower case, was converted into a synonym of the name attribute value “robots”), whether revised or not (it probably was not) in the course of being moved on the WHATWG MetaExtensions wiki page then at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=6434 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=6434&oldid=6433), and whether revised or not (it probably was not) in the course of being moved on the WHATWG MetaExtensions wiki page then at , at https://wiki.whatwg.org/index.php?title=MetaExtensions&oldid=6776 (with the page differences at https://wiki.whatwg.org/index.php?title=MetaExtensions&diff=6776&oldid=6770); it may have a history at Baidu (particular information on the bot or robot “Baiduspider” (with any case) may be available); and the current owner of the bot or robot “Baiduspider” (with any case) is better qualified than I am to create or maintain a specification for the name attribute value “Baiduspider”

Noncandidate
The creator and author of this page tentatively suggested one possibility for a specification without developing it into a proposal. That was for the name attribute value “rights-standard”. The suggestion is in the last substantive paragraph of the opening post of a Talk topic. One or more other people developed it into a proposal. I am leaving that value to other people to consider and maintain as they see fit.
