 Validation is successful, if real-world data is ingested and the information needs of all users in the product lifecycle are met.

 - Transform input data with the formats ReqIF, SysML v1 and v2, STEP and FMI/SSP. Other input formats may follow.
 - Integrate input data with different formats to an interwoven knowledge graph.
 - Create output data with the formats RDF/Turtle, JSON-LD and XHTML.

 - Bring the data into a standardized form to facilitate machine learning and AI applications.
 
 Major requirements (capabilities and characteristics) must be satisfied:
 - Separate syntax and semantics: The software must not be changed, if the ontology is further developed. 
 - Comply with *web-technology* and avoid propriatory formats.
 - Extend the software using a documented, if possible standardized plug-in mechanism.
 
-Collaboration rules:
+## Collaboration rules:
 - This repository has two protected branches, namely 'main' and 'dev', where 'dev' is the default.
 - The 'main' branch keeps just the released versions. In particular, it has a 'docs' folder which is published by GitHub pages.
 - The 'dev' branch merges all development efforts, until a release is made. Then, a pull-request 'main'<--'dev' is initiated.
 - All development tasks are planned in [GfSE/projects/5](https://github.com/orgs/GfSE/projects/5).
 - When a task (an issue) is assigned and work is about to start, the task status is changed to 'in progress' and a new branch is opened
   from within the task. The branch name will thus begin with the issue number.
-- When the issue is done and all tests pass, a pull-request 'dev'<--'NN-issue-name' is initiated.

   'main' may be initiated as described above.
