Is it possible to get metadata information from a previous version of a document in a document library using a SharePoint webservice?

I know I can use the _vti_bin/Versions.asmx webservice to get information about a previous version, but can I get the previous versions metadata?

If it's not possible through webservice is it possible using Client Object Model?

Versions web service is no use in your case. You need to use Lists web service (http:///_vti_bin/lists.asmx) and Lists.GetVersionCollection Method

Returns version information for the specified field in a SharePoint list.

So you need to query field by field and as far as I know there is no method to return all field versions at once.

Your code could look something like this:

WSLists.Lists listService = new WSLists.Lists();
listService.UseDefaultCredentials = true;
XmlNode result = listService.GetVersionCollection(
    "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", "[ITEM ID]", "[FIELD NAME]");
string outerXml = result.OuterXml;

and outerXML looks something like this:

<Versions xmlns="http://schemas.microsoft.com/sharepoint/soap/">
  <Version [FIELDNAME]="[VALUE]" Modified="[TIMESTAMP]" Editor="[USER]" />
  .
  .
  .
</Versions>

I never used this approach but I did some tests (on SP 2010 - but I don't think there is difference). I never found good way to easily get all fields for all versions.

And Client Object Model is SP 2010 feature only but except of FileVersion Class I don't see anything similar to 'Get me item versions with metadata'.
