[OPEN-ILS-DEV] Angular6 update / input needed on template translation options

[Ben Shum]

Hi Bill,

Spinning up a Pootle instance has been on our community to-do list for
awhile as part of our ongoing discussions about the desire/plans to
switch off Launchpad.  I started playing with this during the last
couple conferences locally in a VM on my laptop, but we still have yet
to agree on the exact hosting infrastructures necessary to implement
this for the wider community.  So "quickly" is a matter of getting
everybody back to the table to discuss specific deployment options.

Can you provide us with some sample generated Angular xliff files?
I'd like to do some of my own experiments on the content that we're
going to need to work with.

Also, I found the translate-toolkit help page for xliff2po amusing
where it basically tells us to expect bugs.  I'm wondering if perhaps
this is a problem with the various versions of xliff (1.2? 2.0?) that
seem to be around and perhaps the toolkit not supporting specific
elements in the transitions between PO and xliff at this time.

Thanks for noting the issues though, all the more reason to get Pootle
up and going in my book!
