Joomla Nativity Standards (JNS)

Designing DB

1. Every table should contain published field where it is applicable
2. Every table should contain checked_out and checked_out_time fields if this table records managed in backed.
3. Every table should contain access field where it is applicable

Development

1. Component should be developed in complete MVC model of Joomla 1.5 taking in account all Joomla MVC standards
   
   1. MVC implementation should be done through core Joomla JController, JView, JModel classes.
   2. File structure should conform
2. In administration component should use Joomla core Toolbar to create Functional buttons
3. Every list of records have to have checkin and checkout functionality implemented to prevent double editing record at the same time.
4. Every list of records should have published/unpublished opportunity
5. Every list of records should have access column where it is applicable and its implementation should work in frontend.
6. All error messages should be outputted through JError class

Styling Admin

1. All standard toolbar buttons functions like publish, unpublish save, apply, close, edit, etc should use template images
2. Custom button icon should be in the same style
3. You should think out interface using Joomla interface elements like Sliders, Tabs, Toolbar, ... as much as possible
4. Generating tables and forms standard CSS classes like admintable, adminform, ... should be used
5. Everything component generate and display either in back-end or front-end should be formatted with appropriate core Joomla classes that should guaranty best outlook with any template.
6. Personal formatting may be used but it should not format colors and borders

Styling Frontend

1. All elements rendered on frontend should be formated by core Joomla CSS classes. For example main title: .componentheading, subtitle: .contentheading, data/time: .createdate, .modifydateand so on.
2. Special attention to format tables that list items. Do not forget table classes like .sectiontableheader, .sectiontableentry1, .sectiontableemtry2. I noted that many ignore that.
3. Elements should be placed on the page in general Joomla style.

By one word, user should not think a lot how to adopt component to looks great in his currect template but just install component and use it. I mean that even if user need to edit template just to change positions and order of elements but not color and font size.
