Headlined of the planned

#HashTable - added storing and fetching to/from database so that database maybe manipulated from wiki and the wiki manipulated from the database. In some tasks #Arrays will be much more efficient, but as a catch-all way of storing values in templates in articles hash tables are an excellent idea.
#ArticleFeedback - ( stars of maximum stars ) for reviews*
#ArticleFeedbackv5 - could be used to collect the feedback to a company

Implementation types of extensions

The implementation strategy(s) employed in building this extension. This parameter is used to create categories that help programmers find examples of various MediaWiki specific implementation strategies or patterns. Although the values of this parameter sometimes coincide with the use case or purpose of an extension, that is not reason for this parameter. If the values you have chosen for this parameter do not adequately identify the purpose or possible use cases, we recommend you add additional category links as needed.

mw:parser - catchall for uncategorized parser extensions. If you have written a parser extension, please use one of the following more specific types:
- mw:link - customized link markup, e.g. mw:...
- mw:parser function - custom parameterized template markup, e.g. {{#name: ... }}
- mw:tag - custom XML tag markup, e.g. <tagname>...</tagname>

BrokenLinks

They on BrokenLinks:

They on CategoryIndex:

This extensions allows you to create categories of pages where the page is added with key value, which can be displayed on the lists of parties or categories used to select subset of pages from category.

Us on CategoryIndex:

Perhaps this could be utilized to enter datas for many pages in single pages and also propagated to all languages

CategoryIntersection - where are the other set operations ?

H

HashTables

mw:Extension:HashTables - Enhances the parser with hash table functions and a function to store all parameters given to a template.

Us on HashTables: BINGO! Now we need only a way to store these in a database and fetch them from the database and we're set for a system that we can edit wiki and get stored in database and edit database and wiki get affected.

Naturally using #Arrays can be much more efficient then a hash table when there is much sequential access of values / keys tables .. Using a hash table to store all things and no arrays certainly makes much more sense then using an array to store all things and no hash tables.

N

NewArticleTemplates

mw:Extension:NewArticleTemplates

They on NewArticleTemplates:

...

Us on NewArticleTemplates:

Obviously does what it says. Enables per-namespace pre-loadable ( into the edit box ) texts for new articles i.e. we can have a skeleton for creating a new product, brand, company, area, country and NGO etc. no need to copy-paste. Whether the template given for an article can be given if not all things are split into separate namespaces is possible is not know.
