Linking to an unalterable page:

If you wish students to see a page that is permanent, you may create a link in a course syllabus created in Word (or another HTML editor) to the current (or any previous) page, as follows:

  • Navigate to the page; Navigating to CoreChem Density:

http://wiki.chemprime.chemeddl.org/index.php/CoreChem:Density

  • Click on the History Tab
  • Click on the version that you want to link to permanently
  • Copy and paste the URL into your HTML document. For example:

http://wiki.chemprime.chemeddl.org/index.php?title=CoreChem:Density&oldid=3923 This link has a unique Revision Number, in this case 3923, for the page. If a newer version is created, it will have a new identifier.


This process can be automated:

To return the unique Revision Number for any page, substitute its page name in place of "CoreChem:Density" and beginning date in place of "20090505000000" (YYYYMMDDHHMMSS format (year 2009, month May =05, day 05, hour 00, minute 00, seconds 00), in a query formatted like this:

http://wiki.chemprime.chemeddl.org/api.php?action=query&prop=revisions&rvlimit=1&format=xml&rvstart=20090505000000&titles=CoreChem:Density

That will return the Revision Number: 

<?xml version="1.0" ?> 
- <api>
- <query>
- <pages>
- <page pageid="282" ns="0" title="CoreChem:Density">
- <revisions>
 <rev revid="3923" user="Jshorb" timestamp="2009-06-04T22:06:48Z" /> 
 </revisions>
 </page>
 </pages>
 </query>
- <query-continue>
 <revisions rvstartid="3643" /> 
 </query-continue>
 </api>

The Revision Number can be used in the hyperlink:

http://wiki.chemprime.chemeddl.org/index.php?title=CoreChem:Density&oldid=3923
