====== ABBI DokuWiki Information ======

For general information on DokuWiki and its syntax:

[[wiki:syntax | DokuWiki Syntax]] 

[[wiki:dokuwiki | DokuWiki Guide]] 


=====  Access Control Management =====

Pages in ABBI DokuWiki can have different access rights depending on the user group. The access rights are:

  * **N**: No right (permission denied)
  * **R**: Only read access
  * **E**: Editing existing pages
  * **C**: Creating new namespaces, creating and deleting pages
  * **U**: Uploading media (e.g., pictures, document) 
  * **D**: Delete pages, namespaces and media

Access rights are ordered (**N**<**R**<**E**<**C**<**U**<**D**) such as higher rights include lower rights.

In ABBI DokuWiki, access right management is based on user groups and namespaces:

^ Namespace     ^              User Groups                 ^^^^
^ :::           ^ @ALL ^ @abbi_ext ^ @abbi_int ^ @abbi_master ^ 
^ :public:      |  R   |  E        |  E        |  D           |
^ :private:     |  N   |  E        |  E        |  D           |
^ :private_iit: |  N   |  N        |  E        |  D           |
^ :wiki:        |  N   |  R        |  R        |  E           |

where the groups are

  * **@ALL**: all non-registered users
  * **@abbi_ext**: registered non-IIT ABBI staff
  * **@abbi_int**: registered IIT ABBI staff 
  * **@abbi_master**: a selected few who understand what namespaces and access control are about :-). 

There is also a **@abbi_admin** group who can do additional things like moving a page or a namespace, installing a plugin, etc.  

Non-IIT staff must register on the [[https://accounts.rbcs.iit.it | RBCS portal]]. Contact <gabriel.baud-bovy@iit.it> if you want to change your access rights.

==== ABBI namespace structure ====

A namespace is similar to a directory or folder, while pagenames are similar to files. In DokuWiki you can use [[https://www.dokuwiki.org/namespaces | namespaces]] to categorize your [[https://www.dokuwiki.org/pagename | pages ]]. 
 
A partial representation of ABBI namespace structure is: 

<file>  
   root namespace (always present)
     │
     └── 'public' namespace
     │       └── 'media' namespace
     │
     └── 'private' namespace
     │       └── 'media' namespace
     │       │
     │       └── 'ble' namespace
     │       │     └── 'media' namespace
     │       │
     │       └── 'fw' namespace
     │       │     └── 'media' namespace
     │       │
     │       └── 'hw' namespace
     │       │     └── 'media' namespace
     │       │
     │       └── 'app' namespace
     │             └── 'media' namespace
     │
     └── 'wiki'namespace                        
     │
     └── 'software'namespace                        

<\file>

By convention, namespaces and pagenames in this wiki are in //lower cases// and //underscores// are be used to separate words.  

The root namespaces ''public'' and ''private'' are used to define access rights. By default, child namespaces inherit access rights from their parent namepage and pages inherit access rights from their namepages. Therefore, all pages under the ''private'' namespace will have a restricted access as defined previously, etc.

The ''media'' namespace is used to store media (e.g. pictures, videos, documents) that are linked from pages in the corresponding namespace.  For example, the picture file ''pic.jpg'' inserted in page '':private:fw:overview'' should be placed in namespace '':private:fw:media''. 

New pages and namespaces are created by creating a link and editing the page. Exactly where the page is created depends on the syntax of the link:

  * Absolute paths in links start with a colon '':'' or with the namespace
  * Relative paths start with a colon ''.''

For example, let's assume that one creates the following links in the page '':private:development''

  - ''%%[[new_page]]%%'' 
  - ''%%[[:private:new_page]]%%''
  - ''%%[[.ff:new_page]]%%''
  - ''%%[[:private:ff:new_page]]%%''
  - ''%%[[ff:new_page]]%%''
  - ''%%[[:ff:new_page]]%%''

  * 1. is relative to the current namespace and will therefore create the page '':private:new_page'' like 2.
  * 3. starts with a colon is is therefore relative to the current namespace and create the page '':private:ff:new_page'' like 4.  In addition, it will create the namespace ''ff'' beneath ''private'' if it does not exist.  
  * Somewhat counter-intuitively, the syntax of 5. refers to an absolute path. It will therefore create page '':ff:new_page'' like 6. In addition, it will create 'ff' in the root directory if it does not exist. 

[[https://svn.rbcs.iit.it/abbi | ABBI SVN]] should normally be used to manage the development of software within the project. However, it might occasionally be useful to upload in the wiki some software to be distributed (e.g. as a zipfile). Software should be placed in the ''software'' namespace. Access right will be managed on a case-by-case basis.
