<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Images that can be used for package deployment have to be tagged in glance in order to enable the UI to filter the list of images to present to a user (and potentially preselect). Currently the tags are defined in the dashboard code (images/forms.py)
which makes things very inflexible; if I can upload an image and a package that consumes that image, I don’t want to have to make a code change to use it.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anyone who can upload images should also be able to specify tags for them. There is also the question of whether a user should be allowed to tag images that don’t belong to them (e.g. a shared image used by a private package), but I think
that can be punted down the road somewhat.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think this needs to be more dynamic, and if that’s agreed upon, there are a couple of approaches:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">1)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Store allowed tags in the database, and allow administrators to add to that list. Ordinary users would likely not be able to create tags, though they could use pre-defined ones for images they owned.<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">2)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Have some public tags, but also allow user-specified tags for private packages. I think this leads to all sorts of tricky edge cases<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">3)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Allow freeform tags (i.e. don’t provide any hints). Since there’s no formal link between the tag that a package looks for and the tags currently defined in code, this wouldn’t make anything more susceptible to inaccuracies<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It would also be worth considering if there’s value allowing multiple tags per image (I’m on the fence).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Personally, I think that 1) would be an improvement over the current situation that’s reasonably easy to implement; that would allow the bare minimum of flexibility without requiring much extra design. The other options would perhaps be
a longer term goal.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thoughts? If there’s general agreement I will turn this into a blueprint.<o:p></o:p></p>
