<h1 id="rfc.section.1"><a href="#rfc.section.1">1.</a> <a href="#introduction" id="introduction">Introduction</a></h1>
<p id="rfc.section.1.p.1">Security automation assessments (i.e. vulnerability assessment, configuration assessment, etc.) often require enumerations of endpoint attributes to be known before such assessments can take place. As technologies evolve and emerge, enumerations may change and new enumerations come into existence. As such changes to the set of enumerations happen frequently. A problem yet to be solved in security automation is the ability for enterprises to quickly, even dynamically, acquire (or potentially define) enumerations of endpoint attributes and make those enumerations available to the security automation tools operating in their enterprise.</p>
<h1 id="rfc.section.1.1"><a href="#rfc.section.1.1">1.1.</a> <a href="#scope-of-solution" id="scope-of-solution">Scope of Solution</a></h1>
<p id="rfc.section.1.1.p.1">The scope of this solution is constrained to the repository interface, and specifically avoids details about the data models stored in the repository. This is because data models may vary, depending on attribute collection needs. Coarsely, network devices are likely to have models represented using YANG, whereas traditional devices may be represented using OVAL.</p>
<h1 id="rfc.section.2"><a href="#rfc.section.2">2.</a> <a href="#terms-and-definitions" id="terms-and-definitions">Terms and Definitions</a></h1>
<p id="rfc.section.2.p.1">TBD</p>
<h1 id="rfc.section.3"><a href="#rfc.section.3">3.</a> <a href="#repository-interface" id="repository-interface">Repository Interface</a></h1>
<p id="rfc.section.3.p.1">An implementation of a data model repository MUST support the following operations:</p>
<p/>
<ul>
<li>List data models</li>
<li>Get data model X</li>
<li>Add data model</li>
<li>Update data model</li>
<li>Remove data model</li>
</ul>
<p id="rfc.section.3.p.3">Authorizations MUST be considered in an implementation. Listing and getting data models SHOULD be open, but MAY be constrained to authorized entities. Adding, updating, and removing data models SHOULD be restricted to authorized entities only, but MAY be opened to the world. In other words, this document does not take a strong stance on what should or should not be authorized for a given repository.</p>
<h1 id="rfc.section.4"><a href="#rfc.section.4">4.</a> <a href="#repository-data-model-metadata" id="repository-data-model-metadata">Repository Data Model Metadata</a></h1>
<p id="rfc.section.4.p.1">In order for a repository to be queryable, a certain structure of metadata about the data models needs to be described.</p>
<p/>
<ul>
<li>Name</li>
<li>Version</li>
<li>Endpoint applicability</li>
<li>Date created</li>
