Part of the article content is outdated since 2022. SVN is not longer in use; railML®'s Gitlab structure is different. Please update this article to reflect recent events or newly available information. Possibly, you will find further details on the discussion page. Coordination (talk) 11:37, 26 September 2022 (CEST)

🗒️ The subject of this article is accessing, setting and naming developer versions. To learn about published railML® versions and about our release policy, see dev:versions.

Current stable release

In order to get the current stable railML^® package, go to the Download section (link to the railML^® website) whilst logged on.

Current stable releases are railML^® 2.5 and railML^® 3.2 respectively.

Exchange a railML^® file based on unstable schemas

The following XML fragment shows how to exchange railML^® files using unstable railML^® schemas.

<?xml version="1.0" encoding="UTF-8"?>
<railml version="2.1r416"
  xmlns="https://www.railml.org/schemas/2011" 
  xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="https://www.railml.org/schemas/2011 https://svn.railml.org/export/416/trunk/schema/railML.xsd">
  ...
</railml>

• Use the last released version number plus the current SVN number: version="2.1r416"
• Use the last released namespace
  • as default namespace: xmlns="https://www.railml.org/schemas/2011"
  • as prefixed namespace: xmlns:rail="https://www.railml.org/schemas/2011" (not shown above)
• Use the appropriate web-based Schema location at railML.org: xsi:schemaLocation="https://www.railml.org/schemas/2011 https://svn.railml.org/export/416/trunk/schema/railML.xsd"

Note on legacy SVN commits

🗒️ In 2021 the railML® development was migrated from SVN () to GitLab (). Identical commits have different numbers on SVN and GitLab respectively. Template:SVN still allows to find SVN commit numbers in GitLab via the search function. For instance SVN commit 416 corresponds to GitLab commit 5f735749. You will be directed to a search page, where the (usually unique) hit can be clicked or the commitment number can be copied. E.g. {{SVN|416|2}} [416] will present a page linking to the page of GitLab commit {{commit|5f735749}} [5f735749].
