Notes:
object_type is tikipage, blog, etc

tiki_structures: structure_id, root_structure_id, content_id, level, pos, page_alias, parent_id

tiki_structure_item (primary key is structure_item_id):
structure_item_id, item_type, item_id, url, name, description, created_on, last_modified_on,

tiki_structure_pos (primary_key is combination of tiki_structure_id and tiki_structure_item_id):
structure_id, structure_item_id, parent_id, pos

tiki_structure_item_attrib:
structure_item_id attrib_name attrib_value

Note: Unsure if needed or how to do: tiki_structures: level, tiki_categorized_objects: hits, tiki_nexus_menu_item: perm

Structure_item_id - integer used to specify each line/item in the structure. Equivalent to:
tiki_structures: structure_id, tiki_nexus_menu_items: item_id, tiki_blog_posts: post_id, tiki_categorized_objects: cat_object_id

Structure_id - integer used to specify one structure. Equvalent to:
tiki_structures: root_structure_id, tiki_nexus_menu_items: menu_id, tiki_blog_posts: blog_id, tiki_categorized_objects: category_id

Parent_id - integer specifying top level for multi-level menus & structures; Equivalent to:
tiki_structures: parent_id, tiki_nexus_menu_items: parent_id

Pos - integer which specifies position of the menu relates to ALL other items (no matter what level, within same level highier position is displayed lower and parent_id must have position that is lower then any child). Equivalent to:
tiki_structures: pos, tiki_nexus_menu_items: po

Item_type - Type of item object, describes what type of item_id this is. Can be:
content_id - Item_ID is Content_id
blog_id - Item_ID is Blog_id
structure_id - Item_ID = Structure_ID
URL - Item_Id is not used, instead URL specifies full URL
Equivalent to:
tiki_categorized_objects: object_type, tiki_nexus_menu_items: url_type

Item_id - id of the content for this item, usually same as Content_ID. Equivalent to:
tiki_categorized_objects: object_id, tiki_nexus_menu_items: url, tiki_structures: content_id, tiki_blog_posts: content_id

Note: Possibly get rid of Item_type and replace Item_id in table with Content_ID

URL - when its non-standard or external object, it specifies full URL to redirect to, this is used when item_id is NULL. Equivalent to:
tiki_categorized_objects: href, tiki_nexus_menu_items: url

Name - Short name that will appear when listing this structure instead of original page_name (if not present, original name from structure is to be used). Equivalent to:
tiki_categorized_objects: name, tiki_nexus_menu_items: title, tiki_structure: page_alias

Description - Longer description that maybe used. Equivalent to:
tiki_categorized_objects: description, tiki_nexus_menu_items: hint

Created_On - Date when this structure item was created. Equivalent to:
tiki_categorized_objects: created

Last_Modified_On - Date when this structure item was last modified

Attrib_name - name of the additional attribute (specific to certain structures). This can be: "trackback_to", "trackback_from"

Attrib_value - arbitrary data value


tiki_structure (primary key is structure_id):
structure_id, user_id, structure_name, structure_description, parent_id, created_on, last_modified_on

tiki_structure_types (primary key is structure_type_id):
structure_type_id, structure_type_description, handler_class, handler_package, handler_file

Note: See tiki_content_types for reference as to how handler_class, handler_packages, handler_file would be used

tiki_structure_objects (primary key is structure_object_id):
structure_object_id, structure_id, structure_type_id

Note: ''There is one-one correspondence from structure_object_id and actual object_id (such as
blog_id or nexus_menu_id) that is using the structure. However not all objects that use this structure may have their own object table and since multiple of the same type of objects could be created that use the same strucuture, there is a need for unique structure_object_id. Additionally if structure_object_id was not there and for example nexus_menu was referring directly to structure_id, it would have created a problem when menu is deleted as then you have to specifically check if there are any other menus using the same structure before deleting from tiki_structure_objects table''

tiki_blogs (replaces original, primary key is blog_id):
blog_id, structure_object_id, public, posts, max_posts, hits, activity, heading, use_find, use_title, add_data, add_poster, allow_comments

tiki_nexus_menu (replaces original, primary key is menu_id):
menu_id, structure_object_id, plugin_guid, title, description, menu_type, editable

Note: title and descript can be removed from nexus_menus and tiki_structure title and description used intead, however for menus it might be good to be able to override it and there is nothing wrong with just having it be NULL be default
