 Key-value Storage
 #################
+
+- Key-Value Storage is needed because there are (legacy) applications which require a KVS
+- There are multiple Key-Value Storages allowed per application
+- There must be an update mechanism from different versions of a KVS to another version
+- When are modifications persisted? Configurable?
+- The same KVS should be read/writeable from C++ & Rust.
+- Supported Datatypes: Primitive Datatypes & Non-Primitive Datatypes; To be coordinated with IPC/Communication CTF, to use the same datatypes
+- Tooling to modify/access content of KVS "from the outside"
+- KVS should store default values
+- Integrity of the KVS should be checked

+Abstract
+========
+
+[A short (~200 word) description of the contribution being addressed.]
+
+
+Motivation
+==========
+
+[Clearly explain why the existing platform/project solution is inadequate to address the topic that the Feature Request solves.]
+
+    .. note::
+     The motivation is critical for Feature Requests that want to change the existing features or infrastructure.
+     It should clearly explain why the existing solution is inadequate to address the topic that the Feature Request solves.
+     Feature Request submissions without sufficient motivation may be rejected.
+
+
+Rationale
+=========
+
+[Describe why particular design decisions were made.]
+
+
+   .. note::
+      The rationale should provide evidence of consensus within the community and discuss important objections or concerns raised during discussion.
+
+
+Specification
+=============
+
+[Describe the requirements, architecture of any new feature.] or
+[Describe the change to requirements, architecture, implementation, process, documentation, infrastructure of any change request.]
+
+   .. note::
+      A Feature Request shall specify the stakeholder requirements as part of our platform/project.
+      Thereby the :need:`RL_technical_lead` will approve these requirements as part of accepting the Feature Request (e.g. merging the PR with the Feature Request).
+
+
+Backwards Compatibility
+=======================
+
+[Describe potential impact (especially including safety and security impacts) and severity on pre-existing platform/project elements.]
+
+
+Security Impact
+===============
+
+[How could a malicious user take advantage of this new feature?]
+
+   .. note::
+      If there are security concerns in relation to the Feature Request, those concerns should be explicitly written out to make sure reviewers of the Feature Request are aware of them.
+
+
+
+Safety Impact
+=============
+
+[How could the safety be impacted by the new feature?]
+
+   .. note::
+      If there are safety concerns in relation to the Feature Request, those concerns should be explicitly written out to make sure reviewers of the Feature Request are aware of them.
+      ToDo - Link to the Safety Impact Method
+
+[What is the expected ASIL level?]
+[What is the expected classification of the contribution?]
+
+   .. note::
+      Use the component classification method here to classfiy your component, if it shall to be used in a safety context: (TODO: add link to component classification).
+
+
+License Impact
+==============
+
+[How could the copyright impacted by the license of the new contribution?]
