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

Top_Level_Item_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

Object_type - Type of object, describes what type of object_id this is. Can be:
content_id - Object_ID is Content_id
blog_id - Object_ID is Blog_id
structure_id - Object_ID = Structure_ID
URL - Object_Id is not used, instead URL specifies full URL
Equivalent to:
tiki_categorized_objects: object_type, tiki_nexus_menu_items: url_type

Object_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

URL - when its non-standard or external object, it specifies full URL to redirect to, this is used when object_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

Note: Possibly get rid of Object_type and replace Object_id in table with Content_ID
