What does this warning message mean?
While copying and pasting contents from external sources into the knol editor, after saving your content you may encounter a warning dialog:
 |
| An unexpected content modification warning dialog |
There are two causes for this warning message: unsafe tag removal, and visible content loss. These will be explained in the next sections.
Unsafe tag removal warning
Your HTML either contains unsafe tags (iframe, embed, styles, script) or extra attributes. They were removed and won't be visible when the page is viewed by others
This message indicates that while saving the HTML contents of the knol editor, we made modifications to that content which may have been unexpected and resulted in a removal of some HTML tags and/or content within those tags. Here is a partial list of tags that we do not allow in Knol HTML contents and are removed whenever they are encountered during a save operation:
- <embed />
- <object />
- <iframe />
- <script />
- <style />
These tags pose security risks to the visitors to your knol. Each of these tags have the potential to expose private authentication information without the visitors' consent. Some of these tags can also deface portions of the knol page in a way that may confuse or disconcert others.
While the embed, script, object and iframe tags can be useful in their ability to inject content from other websites into Knol, we cannot verify that the contents from other websites won't expose a visitor's knol authentication credentials to a potential attacker. We do allow for Google content embedding because these widgets have already passed a security review that deems them safe for use in Google's sites.
The script and style tags can be used to style the content of your knol, but it can also be used to re-arrange, hide or deface the rest of the Knol viewer's user-interface elements. This would hinder visitors ability to navigate within the site and use Knol effectively.
Visible Content Loss Warning
It appears as if some of this content may have been lost during last save operation. We never expect for this to happen, so you may want to make an additional copy of your recent changes just-in-case.
This message is a bit more serious and indicates that a non-trivial amount of visible HTML contents were removed during the normal process of converting the HTML in the Knol editor into a safe, valid form that is presentable to other Knol visitors.
The most common cause of this warning is a removal of content contained within some of the other dangerous tags noted above. If the a warning of this type occurs without the previously noted dangerous tag removal warning, it could mean that some of the content visible in the Knol editor window will not be seen once the editor is closed or when someone else views the knol.
We don't ever expect for content loss like this to occur. If it does, our team is alerted in a timely manner and we will investigate the cause of the potential loss.
What to do when you encounter these warnings
If you are copying and pasting content from another source such as a desktop document editor, you should evaluate whether the formatting or textual loss is acceptable to you.
If it is not, you may try to retain some of your formatting. Here is one technique: Export your files as HTML first, then copy/paste from that editor into Knol. The process of exporting the content as HTML may resolve some of the formatting changes before that content reaches the Knol editor.
You might also try to use the Knol Import tool instead of cut-and-paste.
If you are copying and pasting content from another website, you may consider copying only the text and omit any Video players, Music players or other embedded content which is not permitted in Knol. Have a look at this knol on Embedding objects in your knol for more information on how to safely include YouTube videos, Google Videos and other types of Google objects into your knol.

Something else going on
* All of my work has been confined to Knol's tools and to Google Docs, which I have been using to prep tables of addresses. This should be a very simple task, but it is not. The table feature of Knol sucks. Google Docs table is better, but inconsistent. I have had to edit the HTML for every table in the article. My method is copy and paste from Doc to Knol. The solution of course is to beef up the Knol table tool to make it publishing friendly. If you ask, I'd be happy to describe the need.
* Yesterday, I made many new entries in the article, hyperlinking most of them. Today, the hyperlinks are missing. What gives? Hours of work have been lost. Now I have to rebuild dozens of links, wondering if they will be lost again. And again. Frankly, I'd rather redo the article ONCE and publish it elsewhere.
Don't make me move the article. Please help. Thanks,
Murry
We are sorry to hear about those problems.
We have documentation on known limitations of the table editor, here:
http://knol.google.c
It would be good to at least upgrade the capabilities of the knol table editor to match Google Docs.
For the missing hyperlinks, we can look at the CBCT X-ray document and try to see what we wrong. Was there a particular time, or version number, at which the links disappeared? I
If there is a specific Google Docs file that is failing to import into Knol, can you share that with, or email that to: knolhelp@gmail.com, and we can look at that test case?

From yesterday, take a look at listings under Great Britain/Scotland. There's more than a dozen links, painstakingly researched, that are missing.
And, a bunch more awaiting research at the end of the article. I don't want my research to fail. Thanks for your help. It a pleasure working with you.
