In MediaWiki looking for following solution. A member of one group must be able to edit only the pages created by members of that group. A member of one group must not be able to edit the pages created by members of another group which this person is not a part of.
make following entry in LocalSetting.php
$wgGroupPermissions['development']['edit'] = true;
$wgGroupPermissions['development']['createpage'] = true;
$wgGroupPermissions['development']['upload'] = true;
$wgGroupPermissions['development']['move'] = true;
$wgGroupPermissions['development']['protect'] = true;
MediaWiki:Group-development(content: Development)
MediaWiki:Group-development-member(content: Development)
MediaWiki:Grouppage-development(content: Project:Development)
# add an additional protection level restricting edit/move/etc. to users with the "development" permission
$wgRestrictionLevels[] = 'development-team';
# give the "development" permission to users in the "development-team" and "development" groups
$wgGroupPermissions['development']['development-team'] = true;
# give the "development-team" permission to sysops (needed so sysops can apply this protection level to pages)
$wgGroupPermissions['sysop']['development-team'] = true;
#It can be implemented using "$wgRestrictionLevels"mediawiki.org/wiki/Manual:$wgRestrictionLevels
