10
11 * Wiki Talk Pages : And the respective Talk Pages as sub pages or as comments of the respective pages.
12 ( Discussion pages)
13
14 * User Pages : We can use them to create XWiki User objects.
15
16 * Templates : The contents of any page on wiki can be inserted into other pages. Pages that are to be transcluded are called "templates".\\We can treat them as normal Wiki Pages and handle them using include macro.
17
18 * Redirect pages : We can replace the content with the page redirection code.
19
20 * Special Pages : We dont need them.
21
22 * CSS/JS Pages. : We can use Skin Extensions. Save the pages as JSX or SSX objects.

26 ====Files or Attachements====
27
28 The files like images, pdfs and other formats are saved locally in a folder. The main resources folder further has three sub-folders archive, temp, thumb.
29 * Main Folder : Place for latest versions of the files. ( eg : Boston_City_Flow.jpg)
30 * archive : Place for the original image files, that have been replaced by newer versions. (archived pic : 20090610045842!Boston_City_Flow.jpg - Time stamp as Prefix )
31 * thumb : A copy of thumb nail or orginal image.

70
71 MediaWiki can be exported in various formats and tools are available.
72
73 * XML format
74 * Directly from Database
75
76
77 ====XML Format Explained====
78
79 XML dumps contain the content of the wiki (wiki pages with all their revisions), without the **site-related data** (it does not contain user accounts, image metadata, logs, etc).
80
81 A typical XML File :
82
83 {{code language=xml}}
84 <mediawiki xsi:schemaLocation="http://www.mediawiki.org/xml/export-0.3/ http://www.mediawiki.org/xml/export-0.3.xsd" version="0.3" xml:lang="en">

157
158 ====Directly from Database====
159
160 We can directly connect to the database. And create a full import of Wiki. In this case we have access to all the data.
161
162 Whats Available :
163 * Access to complete page content with all revisions.
164 * User Data
165 * Links.
166 * MultiLanguage Support.
167 * Archived and Deleted Page Content.
168
169
170 Whats Not:
171
172 * Database has metadata information of files only. So the user should supply the details of File Resources folder before we map them to XWiki Attachments.
173 (includes Images and other file types. )
