Thanks for the summary, this is great feedback. The OGC APIs in general
seem ripe for enhancements and I think some cloud focus is a great idea.
Off the top of my head some other important items in my mind are:
- getting fuzzing going, either as part as OSSFuzz or some other
mechanism (OSGeo infrastructure?)
- converting all source files to C++ - but stopping short of a complete
rewrite
- starting a concerted effort to get our issue list down to a manageable
size - perhaps a bug-a-day initiative
- MapServer 8.0 OSGeo Live support

Some random notes from discussions with various MapServer users and devs at FOSS4G. \
It might help drive discussions at a future PSC meeting. <br> <br>
- OGC Maps API would ideally be the next big MapServer feature, but this would \
require developers and funding<br>
- The R language is popular in the data science community. SWIG supports R so \
R-MapScript bindings could possibly be added in a future version. I can send a \
message to the users-list to gauge interest. <br>
- MapServer is likely to be used as the rendering engine for the pygeoapi backend. \
<br>
- Having to add TEMPLATE "ttt" to layers seems strange to new users. Maybe \
something to look at removing or replacing?<br>
- Both CGI and FastCGI are used in production deployments. FastCGI usage is \
unaffected by the warm-up times for connecting to proj.db in newer versions of PROJ, \
however only CGI can be used in Amazon Lambda deployments. If no reprojections are \
required and inline projections are used, then it may be possible to skip this \
connection (paraphrasing - and possible a misunderstanding on my part, but it could \
be something to investigate). <br>
- From speaking to users, there are a few misunderstandings and gaps in \
docs/tutorials, including:<br>
- how to set up cloud deployments of MapServer<br>
- how multiple Mapfiles are run from a single MapServer instance (there is no \
overhead in having several Mapfiles)<br>
- no tutorials on OGC Features setup<br>
- there are many hidden cartographic features (thanks Lars for your talk that \
highlighted these!)<br> <br>
Finally, people are very keen to try out MapServer 8.0, and lots of people are \
already using that branch. <br> <br>
Feel free to comment or add to any of the above.<br>
