Hi Keerthan, thanks for your interest in XWiki & the GSoC. I'll try answering some of your questions below.

Most of the time, the use case will be to import a full wiki rather than subparts, thus links would be preserved. If you want to let users import/export only subarts of a wiki (such as a space or a single page), you should provide them with a warning that some links will be broken rather than trying to import all pages that are linked to. Or you could make importing liked to pages an option. It could result in surprised users if someone tries to export / import one page and ends up with the 76 pages that page linked / was linked to ;-)

Since the most common use case is to import a full wiki, it shouldn't be much of an issue. to Some metadata can be conserved across systems. For instance, the date when the page was created, its edition date and its previous versions might need to be preserved (if that's technically feasible). Thus it basically means taking care of all the information associated with the page other than its content. destionation B You could start by looking at the XWiki 2.0 syntax and see everything it allows. I think that when trying to convert pages from other wikis (specifically Confluence) you will run in the following issue: some pages use macros that are defined elsewhere on the system and won't work correctly when imported in XWiki.

For pure content, you should be able to import it all in XWiki without much of a problem. For content generated by a script, you could try to identify it and then issue warnings in your output such as "this is specific content that couldn't be converted". See my answer above about retrieving the content of linked to pages.

Have you already looked at the content of a MediaWiki, Confluence and XWiki export file?

In XWiki's case, data is stored in a XML format. It might be the same for Confluence & MediaWiki. If it is, you might be able to use XSLT to convert one XML format to another.

the on issues I think that trying to convert everything is too idealistic. In the case of the Office Importer, content that cannot be converted properly is stripped and warnings are issued for unsupported macros for instance. I'll let Asiri tell you more about the Office Importer conversion behavior if needed.

XWiki 1.0 syntax was using the Radeox parser while XWiki 2.0 syntax is using WikiModel. You would definitely be working with WikiModel a lot, improving WikiModel's Confluence & MediaWiki syntax parsers so that they can eventually issue XDOM elements.

to You can get an input file from the Confluence instance you will have installed on your machine. You can also give a look to XE 1.8 default XAR (available to download from XWiki.org) to see what the expected result looks like

Hello, I now have a good understanding of existing works regarding Parser and Renderer for differents wiki syntax within wikiModel. I am coming with some new questions. Does Xwiki provide some kind of API for retrieving a remonte page from another wiki just like using XWikiXmlRpcClient to copy Xwiki Pages ( I followed some previous discussion about Xwiki Batch).

Use Case 1: User provide URL to a wiki page in another wiki and press the export button. The expected result would be : a) the source wiki provide an export tools then we can use this tools to export b) the source wiki does not provide an export tools then in this case we have to find a way to export After exporting we need to get the remote page and then wikiModel API in order to parse and convert into a proper format to the destination wiki.

Use Case 2: The user provide an exported XML from a destination wiki. In this no problem with retrieving remotely the page.

Are they anything wrong with this approach ? Many thanks

Hello Vincent, Thank you for your reply. 2009/4/2 Vincent Massol &lt;vincent(a)massol.net&gt; Thank you. I already had a look, Guillaume sent it to me in one of the previous thread. In order to perform export or import , the created toolI can follow the next few step : Step 1: Ask for operation type ( export or import) Step 2: Ask for information about the source wiki ( wikiType (mediaWiki,Confluence...), address,username, password).In case of the operation is export we know that the wiki type is Xwiki. Step 3: Ask information about page(s) to be exported Step 4: Ask for information about the destination wiki (address,username, password).In case the operation is export we don't need information about address, username,password.

If Import Step 5: Perform import (1) If Export Step 5: Perform export (2) Does the following make sense ? I will give more information about (1) and (2) in the proposal. Thanks, Regards, Keerthan Sure I understand. I said XML because I was looking at mediaWiki and get some xml file but I understand the input format can be of any kind.

Hello Vincent, 2009/4/2 Vincent Massol &lt;vincent(a)massol.net&gt; Apologize for my explanation, It was not quite clear.Step 1 to 4 are not all about providing
