</div>I think it actually increases the confusion, and we'd need to build some<br>
central numbering authority to make sure we don't reuse the same number...<br>
<br>
OSSAs (and CVEs) are vulnerabilities, so they are serial events very<br>
related to the time of their publication, hence the numbering. OSSNs are<br>
more like security best practices: and those are permanent, eternal and<br>
their order doesn't matter that much. What you need is a convenient way<br>
to uniquely identify them, and then a mechanism to publish updated<br>
version of them if need be.<br>
<br>
For example you could use a single serial number with a date-based<br>
edition version, like "OSSN 12 (2014-01-20 edition)". That would let you<br>
revisit some topics as the software evolves over time.<br>
<br>
(In summary, OSSAs are like a calendar with events, while OSSNs are like<br>
a reference book with chapters. You would not number book chapters after<br>
the date the chapter was originally written).<br>
<br>
About CVEs: since anybody can request a CVE to be assigned about a<br>
specific issue and everyone has a different opinion on what constitues a<br>
"vulnerability", there have been a number of issues in the past that had<br>
CVE assigned to them and did not trigger an OSSA. They tend to fall into<br>
two categories though: CVE assigned by the VMT but not triggering an<br>
OSSA, or CVE assigned by some other party (generally a distribution).<br>
For that reason I don't think you need to be concerned too much about<br>
CVE assignment. To handle the corner case where one is warranted but<br>
nobody ever assigned one, you can always ask the VMT or this list for one.<br>
