2.3. EUROCONTROL eAIP - Publication Process
2.3.1. Default process
This diagram shows the default eAIP production process from XML production to HTML and paper AIP publication. Technologies used on this process are mentioned as well.
The advantage of this process is that the both the browsing format and the printing format are generated from the same XML files, which can be made available to the user.
2.3.1.1. Alternate process
It is also possible that both the XML files and the printing format (PDF) are produced from another source. Structured text editors, such as Adobe FrameMaker, are able to produce export files both in PDF and in XML format. The advantage of such an alternate process is that the generation of the PDF files is straight-forward, as done by the editing tool.
On the other side, the XML export process is usually embedded into the software tool and the editors do not have much control over it. Therefore, the editors must ensure at every issue that there are no discrepancies between the XML/HMTL content on one side and the PDF content on the other side. The users do not have access to the original file sources which were use to produce the XML and PDF format.
2.4. Open source

Chapter 3. eAIP Specification
3.1. Status of the Specification
The eAIP DTD 1.0.3 is the current stable release. This means that it can be used to produce an eAIP or to develop software based on it without the risk of loosing pace with the eAIP DTD development.
Obviously, a stable release does not mean that the DTD will never be changed. Subsequent eAIP development will result in new versions being published:
.
major updates, which greatly transforms the structure of an eAIP document, will receive major version numbers: 2.0, 3.0, etc.
.
changes in the content model that keep the general structure but invalidate previous eAIP will receive minor version numbers: 1.1, 1.2, etc.
.
small changes, which do not invalidate a previous minor version, will have sub-minor version numbers such as 1.0.4, 1.0.5, etc.
At the time of the writing, there were no plans for such changes. Any future changes will be implemented only after consultation with the eAIP Specification stakeholders.
