Tips, warnings, and
frequently asked questions
The ambition of this page is to help users quickly find out what
they need to know about open web pages. It consists primarily of
lists of common questions with links to their answers.
Warning: the open pages system is no longer
being maintained and some of its features may no longer work. In
particular, the email features (subscribe and notify) no longer work
reliably and are not recommended.
Editors: Please try to keep this page clean and clear. It is
intended to contain lots of miscellaneous information; we must make
sure that it is easy to find.
Start by looking at the open-page
mission statement and at how
to author a page. Please do take time to read the styleguide
before you begin editing pages. Links to most of the useful pages can
be found at the bottom of each page.
Q: How can I
recover a previous version of a page?
The open page server keeps an archive
of every version
of a page. Click on the "Restore" link at the bottom of the page
to view old versions.
Q: How can I
upload a non-html file? Why can't I upload non-html files?
Open pages are for collaborative
authoring; they are not places to
park read-only content such as PDFs. These should be located
elsewhere and then linked to from the open page. This is not just
a question of resources---it is a separation of functionality.
Open pages try to do collaborative authoring well; this objective would
only be diluted by trying to provide miscellaneous web space as
well.
If you think about it, you may realize that you already have access to
web space that you can use for read-only web content. And if you
can think of no organization that will provide you with reliable free
web space, then perhaps you can understand why an open-page server
might also decline to do this.
Separating read-only web content from the open-page server is
potentially a problem because it will then be managed differently and
may not be reliable. Unfortunately, this problem may be
unavoidable at the current time. The solution is for someone to
provide a service for cheap, reliable, permanent storage of arbitrary
web content. A permanent data
store.
It is an interesting challenge. The person who solves it will
become famous and rich. Creating this service it is not a small
undertaking and is best done separately from open pages.
Q: Why can't I
get rid of the content at the bottom?
The content at the bottom is mandatory for every open web page. It is
automatically appended to every open file.
Q: How
do I set the title of a page?
If you set an </h1> heading in a page then the title will
automatically
be set to that. Or, in the Mozilla editor, rather than
publishing the page, select "Publish As" from the file menu. From there
you can set the title before publishing.
Q: I
tried to publish a page with an image and it wouldn't work.
Do not publish images with spaces,
hyphens, periods, or other special characters in their file names.
Underbars_are_ok. There is also a limit on how big images can be,
maybe 1 megabyte. Else click
here to find out why publishing failed.
Q: How can I make an open page that is private
to a limited group of people?
This is really easy. You just make the page and don't tell people
outside your group about it. These are called unlisted pages
because they are like unlisted telephone numbers---private just because
nobody knows about them. Tell your group members to put the
secret URLs in their
bookmarks, but not as links on their web
pages. If an unlisted page has a public link to it, then it is no
longer unlisted; google will follow it to find the page.
Q: How can I make a semi-private
page---publicly readable, but writable only by a limited group of
people?
These are also called read-only pages and aliased pages.
What you want is a private page with a public face. The page is
made private by giving it an unlisted or
secret URL, as described in the answer to the question
immediately above. The public face is provided by a public alias URL
that effectively forwards to the secret URL. Group members browse
directly to the page via the secret URL and can therefore edit in the
normal way. But others know only the alias, which can't be edited.
The alias URL must be in a special top-level directory "alias".
For example, on the rlai open server your alias URL might be
"/alias/publicnameofpage.html". The
alias URL is created by browsing to it. This is the same
procedure used to create a normal open page, but here in the alias
directory it instead creates a hidden link to another URL (which you
provide). If you provide the secret URL of an unlisted page then
you will have successfully created a semi-private page.
If you link to a semi-private page, be sure to link to its alias URL
and not the secret URL.
Alias URLs don't seem to be working at the moment.
Q: How
can I add a signature mouseover to a page I am editing in Composer?
Find a page that already has a
mouseover, cut and paste it into your page, then doubleclick it to edit
its text.
Q: How can I get rid of the RLAI logo and
text at the top of the page?
You just delete them in Composer, the
Mozilla editor. To have this done automatically, for every page
you create, see the answer to the next question.
Q:
Problem: publishing succeeds but only text is displayed.
You are strongly encouraged to use
only .html as an extension. In almost every other case the content will
be treated and displayed as plain text. You cannot create an executable
program; You may feel free to upload program files, but they will only display as text. Use of the
.htm is allowed, but discouraged.
Q:
Problem: publishing succeeds but the automatic two lines at the bottom
are missing.
You are strongly
encouraged to use only .html as an extension. .shtml will display
properly, but will not have the Open Web features (the automatic
content at the bottom) and will not edit properly. So don't use it. If
the automatic content is not displaying on a new page, change the
extension to .html. If the extension is .html, weird. Please email.
Q:
Problem: publishing succeeds but images are missing.
Rats. This is Mozilla weirdness when
you publish multiple times
with the "Include images and files" box checked. If you are comfortable
working with source code, click on the "<HTML> Source" tab in
composer and fix it there. If not, email
a description of your problem.
Q:
Problem: publishing succeeds but these weird <> tags keep showing
up.
This was a problem with early versions
of Mozilla/Composer. Update to a newer version and it should
mostly go away. Not entirely though, so maybe it is best just to
delete them and move on.
Q:
How can I find out who is subscribed to a page?
The last item in the bottom material
(the numbers) gives information about the page, including the
subscribers (only the first parts of the subscribers' email addresses
are shown).
Q:
How can I find out how many people have read a page?
The two numbers at the end of the page's bottom material are the number
of visits to the page and the number of subscribers.
Q:
What is the funny little blue-gray square that you see so often in open
pages?
This is called a "signature
mouseover". It is just a little image that puts up a text message
when the mouse rests momentarily over it. In open pages they are
often used as an inobtrusive way to sign a web page or portion thereof,
or to indicate the time at which an extension or other change was made.
Q:
How can I find out how many people have read a page?
The two numbers at the end of the page's bottom material are the number
of visits to the page and the number of subscribers.
