[opencms-dev] when links are moving

[Mathias Lin | SYSVISION]

I am wondering, what is the purpose of the "target" tag in an URI? 
Like in this example, where the attachment is part of a structured content
element, let's say the file is named test.html:

<Attachment>
      <URI>
        <link internal="true" type="WEAK">
         
<target><![CDATA[/sites/com.company.www/_test/downloads/abc.pdf]]></target>
          <uuid>072408c8-4dcd-11de-a07e-00304895511a</uuid>
        </link>
      </URI>
</Attachment>

It seems that the path to the document isn't actually read from the value of
the "target" tag but looked up from somewhere else using the UUID as
parameter?

Because I found that when I move the abc.pdf to another folder, the value in
the "target" tag of the attachment in my test.html is not updated
automatically. But when I open the test.html in the browser and have the
attachment being displayed, the link is displayed correctly.

For example, if I would move the abc.pdf up one folder level and out of the
downloads folder to /sites/com.company.www/_test/abc.pdf, the target value
in my test.html control code still remains
/sites/com.company.www/_test/downloads/abc.pdf, but when viewing the page in
the browser, it will link to the abc.pdf correctly with
/sites/com.company.www/_test/abc.pdf
(Only when I would open test.html in the editor, then save, the target value
would update to the right URL).

So actually everything works fine here, but I am just wondering about the
purpose of the "target" tag then? I also found that I cannot edit the target
value in the control code - when I do, it will always be reverted to the
previous value after I save.
