The purpose of this Web site is to explain the usage of the AIXM model and to enable the AIXM community to collaboratively develop guidance material in support to the AIXM implementations and to provide implementations, including information about such implementations. known implementations. Contributions are welcome, both as simple comments and as content proposal, as explained on the how to contribute page.

The site is organised in three high-level areas of interest: AIXM concepts, AIXM applications and AIXM data sources, coding guidelines and extensions. Editorial and text formatting conventions are explained here: editorial conventions.


Site tree

The AIXM Confluence site is organised in "Spaces", each dedicated to a specific topic or sub-topic. Each space is a collection of pages, organised as a tree. A page may have other child pages. For example, editorial and text formatting conventions are explained in a child page of this root page: see editorial conventions.

How to contribute

There are two main types of users. Based on the type of the user, different access permissions are granted.

Anonymous user (no log–in required, read only)

  • The anonymous user has read access to “published” pages, which is most of the site content. However, some pages might be in development and therefore not yet publicly visible.

Named user (log-in required, read-write access)

  • A named user may have Read & Write access, depending on the Space/Page settings
  • A named user can create content (i.e. write/update content, upload images and files, etc.) and also review and comment all the content pages (i.e. draft versions and published versions).
  • Registration: the AIXM Confluence server is hosted by the European Organisation for the Safety of Air Navigation (EUROCONTROL). Log-in is possible for anyone who has an EUROCONTROL extranet account. However, this still require that the corresponding user is added in a specific group. Please use this registration page in order to request access.


There are two ways of providing comments to the content.

  • Inline commenting: highlight a text or part of a text on a page and keep the cursor over it for a second - a "comment' iconImage Removedappears. Click on it, enter your comment and save it.
  • Comment field: In case you have a general comment relevant for the whole content of a page, please enter it comment in corresponding field displayed at the bottom of each page and save it. This way of commenting allows some additional formatting (e.g. text colouring, italic, bold, etc.) and for named users also some additional functions (e.g. upload of images).

Please note that comment fields remain visible even once the comment was resolved. Therefore,the preferred commenting method is to use inline comments, which may be resolved and closed.

You can also edit your already saved comments.

Editorial Workflow

For some pages, a workflow is implemented in order to allow for reviewing the page content before making it publicly available. First a content page is in the draft status, then it should be assigned for review and finally it will be published.

Space Shortcuts

 In case you have the sidebar expanded on the left-hand side, besides the table of content you will find also some Space Shortcuts on top. These may be external (e.g. to or internal (e.g. to other spaces such as the 'AIXM Coding Overview').
